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 longi-

tudinal submerged arc welding (LSAW), electric resistance weld

pipe (ERW), spiral submerged arc welding (SSAW) pipe by weld-

ing process; it can be divided into oil transportation pipeline, natu-

ral gas pipeline, pipeline steel for acid environment and ocean en-

vironment by medium and environment. Except the oil and natural

gas industry application, this kind of pipeline can be widely used in

water transportation, chemical material and mineral slurry, etc

pressure-bearing transportation. According to different pipe man-

ufacturing processes and applications of users, the detail supply

technology specification could be different.

  1. 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.
  1. The slight fracture rate of the impact test and slight fracture rate of the drop-weight test is the average value.
