ASTM A335 Alloy Steel Seamless Pipes

Alloy Steel contains substantial quantities of elements other than carbon like chromium, silicon, nickel, manganese, molybdenum, tungsten, vanadium as well as limited amounts of other commonly accepted elements like sulphur, manganese, silicon & phosphorous. Addition of these alloying elements is usually done for purpose of increasing hardness, strength as well as chemical resistance of the end product.

Mechanical Tests Specified

Transverse or Longitudinal Tension Test and Flattening Test, Hardness Test, or Bend Test

For material heat treated in a batch-type furnace, tests shall be made on 5% of the pipe from each treated lot.  For small lots, at least one pipe shall be tested.

For material heat treated by the continuous process, tests shall be made on a sufficient number of pipe to constitute 5% of the lot, but in no case less than 2 pipe.

Notes for Hardness Test:

P91 shall not have a hardness not exceeding 250 HB/265 HV [25HRC].

Notes for Bend Test:

For pipe whose diameter exceeds NPS 25 and whose diameter to wall thickness ratio is 7.0 or less shall be subjected to the bend test instead of the flattening test.

 

Other pipe whose diameter equals or exceeds NPS 10 may be given the bend test in place of the flattening test subject to the approval of the purchaser.

 

The bend test specimens shall be bent at room temperature through 180 without cracking on the outside of the bent portion.

 

The inside diameter of the bend shall be 1 inch [25 mm].

Hydrostatic Test

Each length of pipe shall be Hydro tested, at option of manufacture nondestructive electric testing can be used.
