Construction

A335 P5 P9 alloy steel pipe is an alloy structural steel made by hot rolling process.

ASTM A106 seamless steel pipe includes two processes: cold drawn and hot rolled. Among them, cold drawn has higher dimensional accuracy than hot rolled, and the surface of hot rolled steel pipe is relatively rough. The large-diameter seamless steel pipe is hot-rolled steel pipe, and the small-diameter is cold drawn.

API 5L X70 PSL2 pipes are widely used in the oil and gas industry, including oil and gas fields, refineries, natural gas transportation and other fields.

ASME SA-556M Grade C2 seamless pipe is a high-temperature seamless steel pipe produced in accordance with the American Society of Mechanical Engineers (ASME) standard SA-556M.
