Characteristics of seamless pipe

seamless tube process performance test: flattening test, tensile test, impact test, flaring test, hardness test, metallographic test, bending test, nondestructive testing (including eddy current X-ray and ultrasonic testing).

Seamless pipe chemical analysis: the chemical composition of the material for chemical analysis, chemical composition to meet the standard requirements.

Seamless pipe pressure and hydrostatic test is for pressure tube by into the hydrostatic test, which do not maintain the prescribed pressure value not less than 5 seconds, not to disclose, the regular supply hydraulic pressure test is 2.45MPa pressure The pressure test is P = 0.5MPAa.

The corrosion test: industrial corrosion-resistant steel pipe according to standard regulations or agreement between the corrosion of steel pipe corrosion resistance test, no intergranular corrosion.

Seamless pipe Specification, standard and identification

Seamless pipes are extensively applied for the nuclear device, gas, petrochemical, ship building and boiler industries. Seamless pipes dominates 65% of market share in Chinese boiler industry.
