ASME B73.2-2016

Specifications for Vertical In-Line Centrifugal Pumps for Chemical Process

Published by: 2017-04-14 / 2017-04-14 / 47 pages
This Standard is a design and specification standard
that covers metallic centrifugal pumps of vertical shaft
single-stage design with suction and discharge nozzles
in-line. This Standard includes dimensional interchangeability
requirements and certain design features
to facilitate installation and maintenance and enhance
reliability and safety of B73.2 pumps. It is the intent of
this Standard that pumps of the same standard dimension
designation from all sources of supply shall be
interchangeable with respect to mounting dimensions,
size, and location of suction and discharge nozzles (see
Table 1). Maintenance and operation requirements are
not included in this Standard.

ASME PTC 34-2017

Waste Combustors with Energy Recovery

Published by: 2017-03-20 / 2017-03-20
The object of this Code is to provide a test procedure
for evaluating the performance ofwaste fuel combustors
with energy recovery using the boiler as a calorimeter.
These procedures apply when the variability and waste
fuel composition results in a lack of confidence in
obtaining representative samples for laboratory
analysis.

This Code is used to determine (a) the thermal efficiency of system combusting waste fuels (b) the thermal capacity (heat input per unit time) of systems combusting waste fuels (c) the higher heating value (HHV) of waste fuels. The rules and instructions given in this Code apply to all waste combustor systems with energy recovery. Test methods of this code apply to solid, liquid, or gaseous waste fuels. Instructions are given to determine the thermal capacity and thermal efficiency of waste combustor systems by applying the concept of using the boiler as a calorimeter. In addition, the HHV of the waste fuel can be determined by weighing the waste fuel that has been consumed during the test.

Stress Intensity K Factors for External Surface Cracks in Thick-Walled Cylinder Vessels

Published by: 2017-02-07 / 2017-02-07 / 176 pages
This report describes the analysis methods and results for external surface crack stress intensity K solutions
in thick-walled cylinders. The 1040 cases include a range of geometry ratios and crack size ratios for
external axial and external circumferential surface cracks, axial full-width cracks, and 360? circumferential
cracks. These K solutions extend the K factor solutions available in the 2007 API 579-1/ASME FFS-1
Annex C tables. The results are reported as non-dimensional geometry factors that are tabulated in the
appendices along with plots of all the result cases.

Screw and Washer Assemblies-Seams (Inch Series)

Published by: 2017-01-23 / 2017-01-23 / 30 pages
This Standard covers general and dimensional data
pertinent to the various types of screw and captive
washer assemblies, otherwise known as SEMS. SEMS
products may include screws, tapping screws, or bolts
in sizes No. 0 through 1/2 in. diameters in various grades
and materials. The word SEMS is recognized in the
United States as a generic term applicable to screw and
washer assemblies. Also included in this Standard is
Nonmandatory Appendix A illustrating the relative
proportions of plain and conical washer SEMS.

Personnel Lifting Systems

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.

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.
