Seamless Hot Expanded Steel Pipe For Fluid Transportation

Q355B low-alloy high-strength steel is adopted, and the pipe diameter covers 219-426 mm. It is made of seamless tube blank by medium-frequency heating, diameter expansion, sizing and straightening, finishing and nondestructive testing. The steel pipe is seamless, with high density, stable mechanical properties, strong bearing capacity and good sealing performance. It is suitable for the transportation of various fluid media such as water, oil and gas, and is widely used in industrial pipe networks, municipal engineering and long-distance transportation systems, with safety, reliability and long service life.
