Pipe Bend

Our X70, X80 pipe bends are widely used in large engineering projects. For example, our X80 D1219.2×22, X70 D1219.2×22 hot-bending bends for West-to-East Gas Transmission Project and Sichuan-to-East Gas Transmission Project have earned trust and praise from our customers.
Our commonly used raw materials are X70 and X80. But our pipe bends can also be made from API 5L GRADE B, X42, X46, X52, X56, X60, and X65.

BENDING RADIUS (R): R=3D、4D、5D、6D、7D、8D、9D、10D。
BENDING ANGLE (θ):15o、30o、45o、60o、90o、135o和180o,and also could manufacture according the angles given by the clients.
STRAIGHT LENGTH (L): The length between two ends general from 300mm-1500mm, and also can product according to the clients' requirement to product.
END BEVEL: according to the bevel of welding pipe fittings construction
WEIGHT: WEIGHT (Kg)=[0.0433(D-T)TRθ]/100000+L(the weight of two ends straight bend)

Seamless bend: 1/2"~24" DN15~DN600
Welding bend: 6"~60" DN150~DN1500
