U-1(g) U-1(g)(1) Unfired steam boilers shall be constructed in accordance with the rules of Section I or this Division [see
UG-125(b) and UW-2(c)].
U-1(g)(2) The following pressure vessels in which steam is generated shall not be considered as unfired steam
boilers[不能被认为是非火焰直接加热蒸汽锅炉], and[并且] shall be constructed in accordance with the rules of this
Division:
(a) vessels known as evaporators or heat exchangers;
(b) vessels in which steam is generated by the use of heat resulting from operation of a processing system
containing a number of pressure vessels such as used in the manufacture of chemical and petroleum
products;
(c) vessels in which steam is generated but not withdrawn for external use.
Table U-3 Added ISO-148(Part 1, 2, & 3) to Table U-3 [在表 U-3中增加 ISO-148(第 1, 2和 3部分)]
Charpy Pendulum Impact Test Part 1: Test Method, ISO 148-1: 2006 [Charpy摆锤冲击试验,第一部分:试验
方法, ISO 148-1:2006]
Charpy Pendulum Impact Test Part 2: Verification of Test Machines: ISO 148-2:2006 [Charpy 摆锤冲击试
验,第二部分:试验机的验证, ISO 148-2:2006]

UG-84(b)(1) is revised to add ISO-148 (Parts 1, 2 & 3) as
acceptable for impact test procedures and apparatus in
addition to SA-370.
It was discovered that there are virtually no ASTM strikers
available for use throughout Europe, Asia or Australia. It was
also learned that the ISO striker profile has no real effect on
absorbed energy values up to 74 ft-lbs. In materials with
toughness in excess of 75 ft-lbs, the ISO striker is slightly
more conservative and will produce absorbed energy values
that are slightly lower than those obtained using the ASTM
striker. Lateral expansion values will vary no more than .001
inch when based on acceptance criteria of .015 inch lateral
expansion. Based upon these facts it is proposed that impact
testing in accordance with ISO-148 also be permitted in
UG-84(b)(1).
[UG-84(b)(1)已经修改,除了 SA-370 以外,对于冲击试验的程序
和设备,允许采用 ISO-148(第 1, 2和 3部分)
.]
UG-11(c) (5) UG-11(c)(5) added under UG-11(c) “Welded Standard Pressure Parts for Use Other Than the Shell or Heads of a
Vessel." [在 UG-11(C)下增加 UG-11(C)(5) ”除容器筒体或封头以外的标准焊接承压件”]
(5) The Manufacturer of the vessel to be marked with the Code Symbol shall be satisfied that the parts are
suitable for the design conditions specified for the complete vessel in accordance with the rules of this
Division and that the requirements of (1), (2), (3) and (4) above have been met for each welded standard
pressure part.
[负责打容器规范钢印的制造厂应该获得确认,即这些零件适合符合本规范要求的容器设计要求, 并且上述(1),(2),(3)
和(4)的要求也得到满足.]
The addition of UG-11(c)(5) is proposed to address a concern
that the vessel Manufacturer needs to verify that welded
standard pressure parts comply with the rules of this Division.
Similar words are already provided at the end of UG-11(a) and
UG-11(b).
与 UG-11(a), UG-11(b)最后部分的叙述相一致,即容器制造厂要
验证标准焊接承压件符合规范的要求.
UG-14(b), (b) Except for flanges of all types, hollow cylindrically-shaped parts [up to and including NPS 4 (DN l00)] may be
machined from rolled or forged bar,[用轧制或锻制的棒料机加工] provided that the axial length of the part is
approximately parallel to the metal flow lines of the stock. Other parts, such as heads or caps [up to and including
NPS 4 (DN 100)], not including flanges, may be machined from rolled or forged bar. [可以用轧制或锻制的棒料机加
工] Elbows, return bends, tees, and header tees shall not be machined directly from barstock.
This change would make UG-14(b) consistent with UG-14(a),
SA-182 A06 5.4 and 6.5; SA-403 A06 4.1, 5.12 and 6.4, and
Code Case 2148, which do not have any requirement for
“hot-rolled bar” and would permit other cold-rolled bar.
Annul Code Case 2148 six months after publication of the
changes
与 UG-14(a)保持一致, 不要求”热轧棒料”.

Explanation

UG-35.2(d) UG-35.2(d)(1) Quick-actuating closures that are held in position by a locking mechanism designed for manual
operation shall be designed such that if an attempt is made to open the closure when the vessel is under
pressure, the closure will leak prior to full disengagement of the locking components and release of the
closure. The design of the closure and vessel shall be such that any leakage shall be directed away from the
normal position of the operator.
(中文翻译略)
It has been pointed out the paragraph UG-35.2(d)(1) can
misinterpreted to require a closure to leak when the locking
mechanisms are still fully engaged. This is not the intent of
this paragraph. The paragraph is intended to make sure that if
someone ties to open a closure which is under pressure that it
will leak before the locking mechanism is fully disengaged and
the closure is released. The re-wording clarifies this design
requirement. In addition was pointed out that the designer of
the closure may not know the location of the operator since he
may not be the designer of the vessel or system. The
re-wording clarifies this requirement
没有技术上的修改,只是叙述更清楚.
UG-36(b)(1) UG-36 Openings in Pressure Vessels
…
(b) Size of Openings
(1) Properly reinforced openings in cylindrical and conical [锥型] shells are not limited as to size except with the
following provisions for design. The rules in UG-36 through UG-43 apply to openings not exceeding the following: for
vessels 60 in. (1500 mm) inside diameter and less, one-half the vessel diameter, but not to exceed 20 in. (500 mm);
for vessels over 60 in. (1500 mm) inside diameter, one-third the vessel diameter, but not to exceed 40 in. (1000 mm).
(For conical shells, the inside diameter as used above is the cone diameter at the center of the opening) [(对
于锥型筒体, 上述所指的内径是开孔中心处的锥体直径)]. For openings exceeding these limits, supplemental rules of
1-7 shall be satisfied in addition to UG-36 through UG-43. Alternatively, openings in cylindrical or conical shells
exceeding these limits may be designed for internal pressure using the rules of 1-10 in lieu of those given in
1-7(a) and / or 1-7(b). [作为另外一种方法,在圆筒体或锥形壳体上的超过这些限制的开孔也可以以内压按照附录 1-10
的
来设计,而不必按照附录 1-7(a) 和/或 1-7(b).]
Added new appendix 1-10 for alternative method for design of
large openings and revised UG-36(b)(1) to refer to it.
Clarified that cones are also included in the reinforcement
design rules in these sections. A note is also added to
Appendix 1-7(b)(1) limiting application of the 1-7(b) rules to
cones with a half apex angle not exceeding 30 degrees
澄清了补强设计也适用于锥体. 在附录 1-7(b)(1)中增加了一个
注解以说明附录 1-7(b)的规定仅适用于锥体半顶角不超过 30度
的情形.
新增加了用于大开孔设计的另一方法附录 1-10.
UG-37 UG-37(h) added under UG-37 REINFORCEMENT REQUIRED FOR OPENINGS IN SHELLS AND FORMED
HEADS [新增 UG-37(h)]
(h) The reinforcement rules in this Division are applicable for internal or external pressure and do not
address the requirements for openings under the action of externally applied loadings (such as pipe
reactions). When externally applied loadings are to be considered, see U-2(g).
[(h)本规范的规定适用于内压或外压,并没有规定适用于承受外部栽荷的开孔的要求(外部载荷指例如管子反作用力).如
果考虑外部栽荷,参见 U-2(g)]
The reinforcement rules in Section VIII Division 1 are
applicable for internal or external pressure and do not address
the requirements for openings under the action of externally
applied loadings (such as pipe reactions). This item was
proposed because of several requests for interpretation that
asked what opening reinforcement rules were applicable
under loads other than pressure. This proposed action does
not change any Code requirements, it merely provides
information that may useful to the designer.
澄清本规范的开孔补强规定适用于内压或外压,不适用于承受外
部栽荷的情形.
UG-37 Text in UG-37(a) revised:
UG-37 REINFORCEMENT REQUIRED FOR OPENINGS IN SHELLS AND FORMED HEADS
(a) Nomenclature. The symbols used in this paragraph are defined as follows:
…
The reinforcement rules of UG-37(a) are not clearly defined
for the case of ERW or autogenously welded pipe or tube. The
definition of “tr” in UG-37(a) implies that the seamless
allowable stress values should be used in the calculation of

E = 1 (see definitions for tr and trn)
E1 = 1 when an opening is in the solid plate or in a Category B butt joint; or
= 0.85 when an opening is located in an ERW or autogenously welded pipe or tube. If the ERW or
autogenously welded joint is clearly identifiable and it can be shown that the opening does not pass thru
this weld joint, then E1 may be determined as using the other rules of this paragraph; or

the required thickness “tr”, even though the shell is
constructed of ERW or autogenously welded pipe or tube.
Past Interpretations VIII-1-92-25R and VIII-1-98-12 also
support the use of seamless allowable stresses for the
calculation of “tr” in ERW or autogenously welded pipe or
tube.
The proposed changes require that “E1” is taken as 0.85 for
all shells constructed of ERW or autogenously welded pipe or
tube, unless it can be shown that no part of the opening
passes thru the ERW or autogenously welded joint. In the
case where the ERW joint is readily identifiable and it can be
shown that the opening does not pass thru the ERW weld
joint, then “E1” may be determined using the other definitions
of “E1” given in paragraph UG-37(a).

UG-42(a)(2),
(c) & (e),
UG-42 REINFORCEMENT OF MULTIPLE OPENINGS
a) (See UG-39 for multiple openings in flat heads.) (a) When any two openings are spaced at less than two times their
average diameter, so that their limits of reinforcement overlap [see Fig. UG-42 sketch (a)], the two openings shall be
reinforced in the plane connecting the centers, in accordance with the rules of UG-37, UG-38, UG-40, and UG-41 with
a combined reinforcement that has an area not less than the sum of the areas required for each opening. No portion
of the cross section is to be considered as applying to more than one opening, nor to be considered more than once
in a combined area
(1) The available area of the head or shell between openings having an overlap area shall be proportioned between
the two openings by the ratio of their diameters.
(2) For cylinders and cones [对于圆筒和锥体] if the area of reinforcement between the two openings is less than
50% of the total required for the two openings, the supplemental rules of 1-7(a) and (c) shall be used.
(3) A series of openings all……..
c) Alternatively, any number of adjacent openings, in any arrangement, may be reinforced by using an assumed
opening enclosing all such openings. The limits for reinforcement of the assumed opening shall be those given in
UG-40(b)(1) and (c)(1). The nozzle walls of the actual openings shall not be considered to have reinforcing value. For
cylinders and cones [对于圆筒和锥体] when the diameter of the assumed opening exceeds the limits in
UG-36(b)(1), the supplemental rules of 1-7(a) and (c) shall also be used.
e) When a series of two or more openings in a cylindrical or conical [或锥体] shell are arranged in a regular pattern,
reinforcement of the openings may be provided per the rules of ligaments in UG-53.
This item was established to make revisions to UG-36, UG-42
and Appendix 1-7 clarifying that cones are also included in the
reinforcement design rules in these sections. A note is also
added to Appendix 1-7(b)(1) limiting application of the 1-7(b)
rules to cones with a half apex angle not exceeding 30
degrees

UG-84 CHARPY IMPACT TESTS
UG-84(a) General. Charpy V-notch [V型缺口] impact tests in accordance with the provisions of this paragraph shall
be made on weldments and all materials for shells, heads, nozzles and other vessel parts subject to stress due to
pressure for which impact tests are required by the rules in Subsection C.
UG-84(b)(1) Impact test procedures and apparatus shall conform to the applicable paragraphs of SA-370 or ISO-148
(Parts 1, 2 and 3) [或 ISO-148 (第 1, 2 和 3部分)]
ISO-148 allows the usage of both Charpy V-notch and
U-notch testing. Inclusion of ISO-148 into the code will require
the words "V-notch" be added to UG-84(a) to ensure that
Charpy V-notch testing is used exclusively.
Include ISO-148 (Parts 1, 2 & 3) for CVN testing procedures &
apparatus (ISO Striker). A recent incident has led to the
discovery that the impact testing apparatus used throughout

most of the industrial world (Europe, Asia & Australia) is not in
compliance with SA-370/ASTM E23 because the Striker
profile on the ISO machine has a different profile than the
profile designated by ASTM. Outside the USA most
companies and testing laboratories are using the ISO impact
testing apparatus in accordance with ISO-148 Therefore, any
impact testing that is performed outside the USA cannot be in
strict accordance with UG-84 as it is currently written. It was
discovered that there are virtually no ASTM strikers available
for use throughout Europe, Asia or Australia. It was also
learned that the ISO striker profile has no real effect on
absorbed energy values up to 74 ft-lbs. In materials with
toughness in excess of 75 ft-lbs, the ISO striker is slightly
more conservative and will produce absorbed energy values
that are slightly lower than those obtained using the ASTM
striker. Lateral expansion values will vary no more than .001
inch when based on acceptance criteria of .015 inch lateral
expansion. Based upon these facts it is proposed that impact
testing in accordance with ISO-148 also be permitted in
UG-84(b)(1).

UG-90(b)(19) UG-90 GENERAL
(b) The Manufacturer has the responsibility of assuring that the quality control, the detailed examinations, and the
tests required by this Division are performed. The Manufacturer shall perform his specified duties. See UG-92 and
10-15. Some, but not all, of these responsibilities, which are defined in the applicable rules, are summarized as
follows:
…
(19) providing for retention of radiographs (UW-51), ultrasonic test reports (12-4), and Manufacturer’s Data
Reports (UG-120), and other documents as required by this Division (10-13). [和本规范附录 10-13规定的其它文

Revise Appendix 10-13 to require the retention of pertinent
records by the Manufacturer for at least three years after
signing of the Manufacturers Data Report.

UG-117(f); UG-117 CERTIFICATES OF AUTHORIZATION AND CODE SYMBOL STAMPS
UG-117(f) Evaluation for Authorization and Reauthorization. Before issuance or triennial renewal of a Certificate of
Authorization for use of the U or UM Stamp, the Manufacturer’s facilities and organization are subject to a joint review
by a representative of his inspection agency and an individual certified as an ASME Designee who is selected by the
concerned legal jurisdiction. A written description or checklist of the Quality Control System which identifies what
documents and what procedures the Manufacturer will use to produce a Code item shall be available for review.
A written report to the Society shall be made jointly by the ASME Designee and the Inspection Agency employed by
the Manufacturer to do his Code inspection. This report is then reviewed by the Subcommittee on Boiler and Pressure
Vessel Accreditation, which will either issue a Certificate of Authorization or notify the applicant of deficiencies
revealed by the review. In such a case, the applicant will be given an opportunity to explain or correct these
deficiencies.
The changes allow the Manufacturers to be audited more
comprehensively.
Revise UG-117(f) to make the retained records available to
the Authorized Inspector (AI) supervisors or Review Teams for
the purpose of performing reviews for the issue or renewal of
Certificates of Authorization.

Certificates of Authorization will be endorsed to indicate the scope of activity authorized. Authorization may include
field operations if the review team determines that these operations are adequately described in the quality control
manual, and this determination is accepted by the Society.
Before issuance or renewal of a Certificate of Authorization for use of the UV or UD Stamp, the valve or rupture disk
device Manufacturer’s or Assembler’s facilities and organization are subject to a review by a representative from an
ASME designated organization. A written description or checklist of the quality control system, which identifies the
documents and procedures the Manufacturer or Assembler will use to produce Code pressure relief valves, shall be
available for review. The representative from an ASME designated organization shall make a written report to the
Society, where the Subcommittee on Boiler and Pressure Vessel Accreditation will act on it as described above.
The purpose of the review is to evaluate the applicant’s Quality Control System and its implementation. The applicant
shall demonstrate sufficient administrative and fabrication functions of the system to show that he has the knowledge
and ability to produce the Code items covered by his Quality Control System. Fabrication functions may be
demonstrated using current work, a mockup, or a combination of the two. Additionally, retained records as
required by this division and the Quality Control System, shall be made available to the Authorized Inspector
Supervisors or the review teams designated by the ASME. [另外, 本规范和质量控制体系要求的保存的记录必须

UG-116(e) &
UG-116(e)(1)
UG-116 REQUIRED MARKING
(e) When radiographic or ultrasonic examination has been performed on a vessel [当射线或超声波探伤已经运
用于一台容器上时] in accordance with UW-11, marking shall be applied under the Code Symbol as follows:
(1) “RT 1” when all pressure-retaining butt welds, other than Category B and C butt welds associated with nozzles
and communicating chambers that neither exceed NPS 10 (DN 250) nor 11⁄8 in. (29 mm) wall thickness [except as
required by UHT-57(a)], satisfy the full radiography requirements of UW-11(a) for their full length [在全部长度上
满足 UW-11(a)全部射线探伤的要求]; full radiography of the above exempted Category B and C butt welds, if
performed, may be recorded on the Manufacturer’s Data Report; or
Nameplate markings as listed in UG-116(e) are currently only
applicable if the vessel has been radiographed and
UG-116(e)(1) states that the marking “RT1” can only be used
if the welded joints have been radiographed over their entire
length. UG-116(e)(2), UG-116(e)(3), and UG-116(e)(4) state
that the markings “RT2”, “RT3”, and “RT4” must be used on a
vessel if the radiographic requirements have been met for
their respective markings even when ultrasonic examination
has been used for the closure seam per UW-11(a)(7). Code
Case 2235-6 allows ultrasonic examination of other welded
joints other than the closure seam in lieu of radiograph
