Historical Version s – view previous versions of standard. Work Item s – proposed revisions of this standard. This specification covers two grades of electric-resistance-welded aatm pipe intended for conveying gas, vapor, water or other liquid.
ASTM A and ASME SA Carbon Steel Pipes and Tubes
The steel shall be made by either or both basic-oxygen or electric-furnace processes. Steel may be cast in ingots or may be asfm cast. The pipe shall be manufactured from flat rolled steel in individual lengths or continuous length by electric-resistance or electric-induction welding without the addition of extraneous material.
The weld seam of electric-resistance welded pipe to Grade B pipe shall be heat astn after welding or processed in such a manner that no untempered martensite remains.
Tensile and chemical requirements of the steel are provided. Specimens of the steel pipes are subject to flattening test and hydrostatic test.
A nondestructive electric test, either electromagnetic eddy current or ultrasonic test, may be preferred as an alternate to the hydrostatic test.
This qstm is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.
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. Pipe having other dimensions Note 1 may be furnished provided such pipe complies with all other requirements of this specification.
A135 Grade A & B Tubing
The pipe is intended for conveying gas, vapor, water or other liquid; only Grade A is adapted for flanging and a153 Note 2. The suitability of pipe for various purposes is somewhat dependent upon its dimensions, properties, and conditions of service, so that the purpose for which the pipe is intended should be stated in the order. The pipe may be furnished either nonexpanded or cold expanded at the option of the manufacturer. When pipe is cold expanded, the amount of expansion shall not exceed 1.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance aastm the standard. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Note 2 — This provision is not intended to prohibit the cold bending of Grade B pipe. Link to Active This link will always route to the current Active version of the standard.
