Pipeline Steel
The series of product is comprised of B, X42, X46, X52, X56, X60, X65, X70, X80, X90 by strength; it can be grouped into longitudinal submerged arc welding (LSAW), electric resistance weld pipe (ERW), spiral submerged arc welding (SSAW) pipe by welding process; it can be divided into oil transportation pipeline, natural gas pipeline, pipeline steel for acid environment and ocean environment by medium and environment. Except for the oil and natural gas industry application, this kind of pipeline can be widely used in water transportation, chemical material, mineral slurry, etc pressure-bearing transportation.
According to different pipe manmanufacturing processes and applications of users, the detail supply technology specification could be different.

- The impact energy in the table above is the average value of 10*10*55mm sample, the allowable single value is not lower than 75% of the average value, and small size sample impact energy is required to count according to the corresponding norm.
- The slight fracture rate of the impact test and slight fracture rate of the drop-weight test is the average value.
