180 Return Bend Alloy Steel ASTM A234 WP5 10" Sch 40 ASME B16.9
Alloy Steel WP5 Pipe Fittings
Best quality180 Return Bend are available in various dimensions and
degrees. Based on the demands of customer, the 10" Sch 40 pipe
bends are made of alloy steel ASTM A234 WP5 according to ASME
B16.9. The quality is guaranteed by our skilled workers.
180 Degree Return Bend, also called U-Bend, is a pipe fitting that
used to change the direction of flows. It is applied in oil and gas
plants, chemical and petrochemical plants, refineries and renewable
energy plants, mostly in heat exchangers. It is welded onto the
pipes so that provides a joint that leak proof, stable and less
possibility for corrosion.
