Our product lineup covers both seamless and welded carbon steel pipe, fully produced to mainstream ASTM international specifications, engineered to handle general fluid delivery, pressure piping, high/low temperature service, structural construction and heavy industrial working conditions.
1. Core Product & Standard Overview
Our carbon steel pipes strictly follow globally recognized ASTM specifications, the most widely adopted grades for global engineering procurement:
ASTM A53 Grade B: General-purpose seamless & welded pipe for medium-pressure fluid, structural and plumbing works, available in black finish or hot-dip galvanized option
ASTM A106 Grade B: Premium seamless pipe designed for high-temperature, high-pressure service, dominant for refinery, power plant and steam pipeline projects
ASTM A333 Grade Series: Low-temperature resistant pipe for cryogenic environments and cold-region pipeline layouts
Supplementary matched standards: ASTM A179, ASTM A192, API 5L (Grade B, X42~X70, PSL1/PSL2 options)
We manufacture two primary production types to fit different budget & pressure demands:
Seamless carbon steel pipe (hot rolled / cold drawn, for high-pressure critical service)
Welded carbon steel pipe: ERW, EFW, LSAW, SSAW for large-diameter, general industrial transmission
