The aim of ASME is to promote art, science and allied science and the practice of mechanical and multi-disciplinary engineering. ASME has developed several codes and standards to enhance public safety and productivity of Engineers. The ASME standards are the sort of technical guides for the designers, manufacturers and users regarding the usage of the product. Some of these standards are written in few paragraphs, while others may run into multiple pages.

Who is ASME? Founded in as the American Society of Mechanical Engineers, today ASME International is a non-profit educational and technical organization with more than , members worldwide. The aim of ASME is to promote art, science and allied science and the practice of mechanical and multi-disciplinary engineering.

ASME has developed several codes and standards to enhance public safety and productivity of Engineers. The ASME standards are the sort of technical guides for the designers, manufacturers and users regarding the usage of the product. Some of these standards are written in few paragraphs, while others may run into multiple pages.

ASME codes set the guidelines for the mechanical engineers to follow to common system of manufacturing not only in US but also in the countries that have adopted ASME standards. However, the manufacturers, inspectors and installers cannot be forced to use the ASME codes and standards, as they are only the guidelines. They will become compulsory only if they have been included in the contract. The ASME standards are effective because they have been universally accepted.

Their use makes communication between the manufacturers and users faster and more effective. Further, the customers will get the same product no matter where they purchase from if they are standard products.

For example, if you have purchased a Weld Neck flange in Houston, if it is standardized item, no matter where you purchase a Blind flange from, it will fit on the flange purchased in Houston. Notes: A Standard can be defined as a set of technical definitions and guidelines that function as instructions for designers, manufacturers, operators, or users of equipment.

A standard becomes a Code when it has been adopted by one or more governmental bodies and is enforceable by law, or when it has been incorporated into a business contract. Its purpose is to assure installation interchangeability for Valves of a given material, type size, rating class, and end connection.

These fittings are designated as Class , , and for threaded end fittings and Class , , and for socket-weld end fittings. These gaskets are dimensionally suitable for use with flanges described in reference flange standards ASME B This Standard covers spiral-wound metal gaskets and metal-jacketed gaskets for use with raised-face and flat-face flanges.

These gaskets are dimensionally suitable for use with flanges described in the referenced flange standards. It includes requirements for welding bevels, for external and internal shaping of heavy-wall components, and for preparation of internal ends including dimensions and dimensional tolerances.

Coverage includes preparation for joints with the following: no backing rings; split or noncontinuous backing rings; solid or continuous backing rings; consumable insert rings; gas tungsten arc welding GTAW of the root pass. Wafer or flangeless Valves, bolted or through-bolt types, that are installed between flanges or against a flange are treated as flanged-end Valves. Alternative rules for NPS 2. Coverage is limited to the following: a Welding Neck flanges Classes , , , , , and b slip-on and threaded Class Flanges may be cast, forged, or plate for blind flanges only materials, as listed in Table 1A.

Requirements and recommendations regarding bolting and gaskets are also included. They have also added Blinds to these two specs. You may note that these specs include only Weld Necks and Blinds.

If you need help deciding which flange best suits your application feel free to contact me. The dimensions are suitable for blanks made of materials listed in Table 1. This standard covers induction bends for transportation and distribution piping applications e.

Process and power piping have differing requirements and materials that may not be appropriate for the restrictions and examinations described herein, and therefore are not included in this Standard. Customary units are provided. This Standard is limited to flanges and flanged fittings made from cast or forged materials, and blind flanges and certain reducing flanges made from cast, forged, or plate materials.

Also included in this Standard are requirements and recommendations regarding flange bolting, flange gaskets, and flange joints. It covers fittings of any producible wall thickness. This standard does not cover low pressure corrosion resistant buttwelding fittings. For ease of use, product threads and gauging are contained in the Standard. There are no changes to the thread or gage designs.

The word pipe is used as distinguished from tube to apply to tubular products of dimensions commonly used for pipeline and piping systems. In contrast, the outside diameters of tubes are numerically identical to the size number for all sizes.

Pipe dimensions of sizes 12 and smaller have outside diameters numerically larger than the corresponding size. The suffix "S" in the Schedule Number is used to differentiate B

ASTM A53 steel

Jump to navigation Jump to search ASTM A53 is a carbon steel alloy , used as structural steel or for low-pressure plumbing. It is commonly available with national pipe thread ends or with plain cut ends. It can be used for steam, water, and air conveyance. It is also weldable and can be used in structural applications, although ASTM A tube, which is available in the same NPS sizes, is sometime preferred. It shall be permissible to furnish pipe having other dimensions provided that such pipe complies with all other requirements of this specification.

WaveMatrix 2 for Dynamic Testing. In order to minimize variability of results and to get the best possible numbers for these rigid coupons, it is necessary to use a machine that has accurate guidance and is as stiff as possible — in all directions, and powered grips that clamp asmt specimen the same way for each and every test. Precise alignment of the grips is ensured by the use of an AlignPro alignment device — this device alows for precise adjustment of the angularity and concentricity of the grips under both no aetm and loaded conditions. Strain measurement can be done via clip-on extensometry over applicable temperature rangesbonded strain gauges logging strain via the test machine strain channelsor video extensometry, through aitk optical grade window on the front of the chamber.

ASTM F 963-17 Requirements

It includes recommendations and precautions for descaling, cleaning, and passivation of stainless steel parts. It includes several alternative tests, with acceptance criteria, for confirmation of effectiveness of such treatments for stainless steel parts. Appendix X1 and Appendix X2 give some nonmandatory information and provides some general guidelines regarding the selection of passivation treatments appropriate to particular grades of stainless steel. This specification makes no recommendations regarding the suitability of any grade, treatment, or acceptance criteria for any particular application or class of applications. These tests include the following practices
