Published by: 2016-12-16 / 2016-12-16 / 38 pages
B30.23 applies to hoisting equipment and accessory equipment covered within certain volumes of the ASME B30 Standard, that is used to lift, lower, or transport personnel in a platform, by wire rope or chain, from hoist equipment, or by a platform that is mounted on a boom of the hoist equipment. The lifting of personnel is not allowed using some ASME 30 Standard equipment. The ASME B30 volume addressing the hoisting equipment to be used shall be consulted for the applicability of the ASME B30.23 volume.

ASME B16.11-2016

Forged Fittings, Socket-Welding and Threaded

Published by: 2017-01-20 / 2017-01-20 / 33 pages
Upon request from industry and government, ASME has been defining piping safety since 1922.
This Standard covers ratings, dimensions, tolerances, marking and material requirements for socket-welding and threaded forged fittings. These fittings are designated as Class 2000, 3000, and 6000 for threaded end fittings and Class 3000, 6000, and 9000 for socket-weld end fittings. B16.11 is to be used in conjunction with equipment described in other volumes of the ASME B16 series of standards as well as with other ASME standards, such as the Boiler and Pressure Vessel Code and the B31 Piping Codes.

Careful application of these B16 standards will help users to comply with applicable regulations within their jurisdictions, while achieving the operational, cost and safety benefits to be gained from the many industry best-practices detailed within these volumes.

Intended for manufacturers, owners, employers, users and others concerned with the specification, buying, maintenance, training and safe use of wrought and forged fittings with pressure equipment, plus all potential governing entities.

ASME B16.23-2016

Cast Copper Alloy Solder Joint Drainage Fittings–DWV

Published by: 2017-01-16 / 2017-01-16 / 94 pages
This Standard establishes specifications for cast copper alloy solder joint drainage fittings, designed for use in drain, waste, and vent (DWV) systems. These fittings are designed for use with seamless copper tube conforming to ASTM B306, Copper Drainage Tube (DWV), as well as fittings intended to be assembled with soldering materials conforming to ASTM B32, or tapered pipe thread conforming to ASME B1.20.1.

This Standard is allied with ASME B16.29, Wrought Copper and Wrought Copper Alloy Solder Joint Drainage Fittings – DWV. It provides requirements for fitting ends suitable for soldering.

This Standard covers:
(a) description
(b) pitch (slope)
(c) abbreviations for end connections
(d) sizes and methods for designing openings for reducing fittings
(e) marking
(f) material
(g) dimensions and tolerances

ASME MFC-7-2016

Measurement of Gas Flow by Means of Critical Flow Venturi Nozzles

Published by: 2016-08-31 / 2016-08-31 / 58 pages
This Standard applies only to the steady flow of single-phase gases and deals with devices for which direct calibration experiments have been made, sufficient in number and quantity to enable inherent systems of applications to be based on their results and coefficients to be given with certain predictable limits of uncertainty. The critical flow venturi nozzles dealt with can only be used within limits that are specified, for example nozzle throat to inlet diameter ratio and Reynolds number. This Standard specifies the geometry and method of use (installation and operating conditions) of critical flow venturi nozzles inserted in a system to determine the mass flow rate of the gas flow rate of the gas flowing through the system. It also gives necessary information for calculating the flow rate and its associated uncertainty. This Standard applies only to venturi nozzles in which the flow is critical. Critical flow exists when the mass flow rate through the venturi nozzle is the maximum possible for the existing upstream conditions. At critical flow or choked conditions, the average gas velocity at the nozzle throat closely approximates the local sonic velocity. Information is given in this Standard for cases in which: (a) the pipeline upstream of the venturi nozzle is of circular cross section; or (b) it can be assumed that there is a large space upstream of the venturi nozzle. The venturi nozzles specified in this Standard are called primary devices. Other instruments for the measurement are known as secondary devices. This Standard covers primary devices; secondary devices will be mentioned only occasionally.

ASME BPE-2016

Bioprocessing Equipment

Published by: 2016-10-14 / 2016-10-14 / 354 pages
The ASME BPE Standard provides requirements for
systems and components that are subject to cleaning
and sanitization and/or sterilization including systems
that are cleaned in place (CIP’d) and/or steamed in
place (SIP’d) and/or other suitable processes used in
the manufacturing of biopharmaceuticals. This Standard
also provides requirements for single use systems and
components used in the above listed systems and components.
This Standard may be used, in whole or in part,
for other systems and components where bioburden risk
is a concern.

ASME PTC 46-2015

Performance Test Code on Overall Plant Performance

Published by: 2016-10-25 / 2016-10-25 / 306 pages
This Code applies to any plant size. It can be used
to measure the performance of a plant in its normal
operating condition, with all equipment in a clean and
fully functional condition. This Code provides explicit
methods and procedures for combined cycle power
plants and for most gas, liquid, and solid fueled Rankine
cycle plants. There is no intent to restrict the use of
this Code for other types of heat cycle power plants,
providing the explicit procedures can be met. For
example, the performance equations and test methods
herein are applicable to the steam cycle portion of a
solar plant, or of a nuclear plant steam cycle. Refer to
ASME PTC 47 for power block thermal performance test
procedures associated with an IGCC plant (Integrated
Gasification Combined Cycle).

This Code does not apply to component testing, for
example, gas turbines (ASME PTC 22) or steam turbines
(ASME PTC 6 or ASME PTC 6.2) or other individual
components. To test a particular power plant or cogeneration
facility in accordance with this Code, the following
must be met:
(a) a means must be available to determine, through
either direct or indirect measurements, all of the heat
inputs entering the test boundary and all of the electrical
power and secondary outputs leaving the test boundary;

(b) a means must be available to determine, through
either direct or indirect measurements, all of the parameters
to correct the results from the test to the base reference
condition;
(c) the test result uncertainties should be less than or
equal to the uncertainties given in subsection 1-3 for the
applicable plant type; and
(d) the working fluid for vapor cycles must be steam.

This restriction is imposed only to the extent that other
fluids may require measurements or measurement methods
different fromthose provided by this Code for steam
cycles.
