Seamless Steel petroleum Pipe

Seamless Steel Pipe 1.Widely used in fluid transmission 2.Over 100 specifications 3.API certificate

Seamless Steel Pipe

Seamless steel pipe has outstanding homogeneity in the circumferential direction and is thus highly resistant to internal pressure and torsion. Taking advantage of this feature, its widely used for transmission of petroleum, natural gas, drilling, pumping and other fluids. Products include over a hundred specifications for the various applications in regular, pressure, submarine, low-temperature, high-temperature corrosion-resistant and other pipelines.
