Advantages of Seamless Steel Pipe

Light Weight

Seamless steel pipe is light weight, its weight is only 1/5 of square steel.

Corrosion Resistance

Seamless steel pipe is resistant to corrosion of acid, alkali, salt and atmospheric environment, high temperature, good impact resistance and fatigue resistance.

Tensile Strength

The tensile strength of seamless steel pipe is more than 8-10 times that of ordinary steel, and the modulus of elasticity is better than that of steel.
