A335 Pipe Material & Manufacture:
ASTM A335 is a ASTM standard specifies Seamless Ferritic Alloy Steel
Pipe for High-Temperature Service. ASTM A335 pipe ordered to this
specification shall be suitable for bending and similar fusion welding,
and for forming operations.
ASTM A335 seamless
pipes.For pipes 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.
Selection will depend upon design, service conditions, mechanical
properties, and high-temperature characteristics.
Each pipe shall be examined by a non-destructive examination method in
accordance to the required practices. The range of pipe sizes that may
be examined by each method shall be subjected to the limitations in the
scope of the respective practices. The different mechanical test
requirements for pipes, namely, transverse or longitudinal tension test,
flattening test, and hardness or bend test are presented.
