Bending Tube


Our pipe bends are widely used in large engineering projects. For example, our X80 X70 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 A53GR. B, A106B, API 5L GR. B, X42, X46, X52, X56, X60, and X65, also could be made from alloy steel and stainless steel.
