FAQ
What is ASTM A234 WPB material?
ASTM A234 WPB is a carbon steel material specification used for butt weld pipe fittings in moderate and high-temperature services.
What is the difference between LR and SR elbows?
LR elbows have a radius of 1.5 times the pipe diameter, while SR elbows have a radius equal to the pipe diameter, making them suitable for tighter installation spaces.
What standard are these fittings manufactured to?
These fittings are manufactured according to ASME B16.9, the international standard for factory-made wrought butt weld fittings.
Can Haihao Group customize pipe fittings?
Yes. Haihao Group can manufacture customized fittings according to customer drawings, materials, wall thicknesses, and project requirements.
