Our X70, X80 pipe bends are widely used in large engineering projects. For example, our X80 1219.2×22, X70 1219.2×22 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.
