ASTM A234 WP22 Steel Fitting, Elbow 90DEG LR BW ASME B16.9
The alloy steel pipe ftting is fabricated with alloy elements in
such as Chrome, Molybdenum, Nickel alloy, Hastelloy alloy,
Monel, Inconel, and etc. To get a higher pressure ratings, better
strength, good corrosive resistance, and longer durability.
It is widely used in oil and gas pipelines, chemical industries,
power plants, nuclear power sites, and in server conditions.
Alloy steel pipe fttings includes buttweld fttings, alloy steel
long radius bend, alloy steel forged fttings and so on.
The alloy steel buttweld fttings adopts ASTM A234 standard, has
WP1, WP5, WPI1, WP12, WP22,WP23 and WP91 grades.
Class level in CL1, CL2, CL3.
ASTM A234 alloy steel pipe fttings inlcludes alloy steel elbows in
long and short radius, alloy steel eccentric & concentric
reducer, alloy steel caps & crosses, alloy steel couplings, alloy
steel tees, alloy steel nipples, alloy steel caps and etc more
forms. It has seamless, welded and fabricated types.
For alloy steel forged fttings, it adopts ASTM A182 standard refers
to steel pipe flanges. Material standard in ASTM A182 FI,
F5, F9, F11 Class 1, F12 Class 1, F22 Class 1ETC.
