ASME SA 335 Grade P91 Alloy Steel Seamless Pipes

ASME SA 335 Grade P91 Alloy Steel Seamless Pipes

ASME SA 335 Grade P91 Specification

ASME SA 335 Grade P91 Alloy Steel Seamless Pipes are Carbon Steel Pipes with subsequent addition of chromium, molybdenum and sometimes vanadium are known as chrome moly Pipes. ASME Specification alloy steel Pipes are used for high temperature service applications. Seamless Alloy Steel Pipes according to ASME SA 335 Grade P91 are reheated and furnished in full annlealed,isothermal annealed or normalised quenched and tempered condition. ASME SA 335 Grade P91 Alloy Steel Seamless Pipes have a typical chemistry with additions of 8.00-9.50 Chromium and 0.85-1.05 Molybdenum. Bearing minimum tensile strength of 415 Mpa ASME SA 335 Grade P91 Pipes have a minimum yield strength of 205 Mpa.

Dimensional Standards of ASME SA 335 Grade P91 Alloy Steel Seamless Pipes

FEDERAL

WWP-404c is similar to ASTM A-53 except that Government inspection and continuous identification marking of electric weld and seamless is mandatory. It covers black and galvanized welded and seamless pipe for flanging, bending, and coiling and for use with fresh water, oil, steam, air, and gas on shore plus a limited number of shipboard uses. Sizes 1/8 inch through 24 inch.WWP-406c is a federal specification comparable to ASTM A-120 (withdrawn 1988). Mills can certify that A-120 pipe in a distributor-s stock meets all the requirements of WWP-406c.

A.W.W.A.

C-200 covers black welded and seamless pipe intended for the conveyance of water in sizes 6 inch and larger. Specification prescribes hydrostatic test pressures for sizes of pipe covered. Tensile, flattening, and bending tests are required.
