Seamless steel pipe is made of the whole round steel, and the steel pipe without weld on the surface is called seamless steel pipe. Seamless steel pipes are mainly used as drilling pipes for petroleum geology, cracking pipes for petrochemical industry, boiler pipes, bearing pipes and high-precision structural steel pipes for automobiles, tractors and aviation.

Tensile Test — NPS 8 and larger — either transverse or longitudinal acceptable Smaller than NPS 8 — weighed in lots.
Larger sizes — by length.
Flattening Test — NPS 2-1/2 and larger.
Bending Test (Cold) — NPS 2 and under.
Shipping--- by container (Apply to a few or common quantity) or in bulk ( Apply to huge quantity)
