Within the text, the SI units are shown in brackets.
Wall thickness may not be more than Normally furnished in square cut ends, fittings with beveled ends can be provided. Active view current version of standard. The fittings shall be made from flat-rolled steel which shall be in the solution annealed condition.
Douglas Barwick – Specifications
Historical Version s – view previous versions of standard. Class WP fittings are subdivided into four subclasses: The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other.
Fittings differing from these standard may be furnished in accordance with Supplementary Requirement S9. Link to Active This aa774 will always route to the current Active version of the standard.
Fittings are pickled and passivated as per ASTM A to maintain corrosion resistance and to prevent surface discoloration from free iron oxidation. ASTM A This specification covers seamless and welded austenitic stainless steel tubing intended for the low or a774 temperature and general corrosion service.
ASTM A774 Grade TP316L
A pipe and tubing is commonly used in the Pulp and Paper mills, food a7774 plants, and other industries where corrosion resistance is essential. With no nondestructive testing required. Pipe or fitting fabrications made with filler metal have been radiographed marked with Class symbol WP-W. A is considered to be the most applicable specification for “as welded” fittings.
Wall thickness may nor be mode than. ASTM A Fittings This specification covers welded unannealed stainless fittings intended for low to moderate temperatures and corrosion service where heat treatment is not required for corrosion resistance.
How to Sstm Us. Base metal analysis are traceable to the original mill asm. Combining values from the two systems may result in non-conformance with the standard. Hydrostatic or non-destructive electric test of each tube. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
The fittings shall be formed by a hot or cold process and shall be awtm by a shielded welding process with or without the addition of filler a74.
When desired, one or more of these may be specified in the order. Fittings can be supplied in a wide range of diameters and wall thicknesses. Users should note that certain corrosive conditions may restrict the use of one or more a74. This process of welding allows the company to supply a large range of thickness and diameters.
ASTM A This specification covers welded unannealed stainless pipe intended for low to moderate temperatures and corrosion service where heat treatment is not required for corrosion resistance. Automatic welding process with the a7744 of filler wire. The A manufacturing process is suited to high-volume production and is generally limited to the diameters and schedule wall thickness shown in ANSI B Pipe is pickled and passivated as per ASTM A to maintain corrosion resistance and to prevent surface discoloration from free iron a77.
The term “fittings” applies to butt and socket welding parts such as 45 and 90 elbows, tees, reducers, wyes, laterals, crosses, and stub ends.
Class WP-S fittings are those manufactured from seamless product by a seamless method of manufacture marked with class symbol WP-S. No nondestructive testing is performed and the fittings are unannealed. This abstract is a brief summary of the referenced standard.
The steel materials shall also undergo mechanical tests and shall conform to the required values of tensile strength, yield strength, elongation, and hardness. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Specially items can be ordered A pipe with immediately deliver available from a complete inventory standard sizes up to 24″. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. A is considered to be the most applicable specification for “as welded” pipe and zstm from it only that a transverse guided bend test and a transverse tension test are required per lot.
The principal manufacturing procedures specified under A are: As-Welded fittings are usually used where corrosion resistance is essential.
