Petroleum cracking pipe is a kind of strip steel product with hollow section and no seam joint around. As an economic cross section steel material, petroleum cracking tube is extensively used in manufacturing structural and mechanical parts, such as petroleum drill rod, automobile transmission shaft, bicycle frame and steel scaffold used in construction. JST petroleum cracking pipe can also be used as seamless steel tube applicable in refinery, heat exchanger, pipeline and other applications.

Advantages of Petroleum Cracking Tube
  • We use petroleum cracking pipes to make ring-shaped work pieces. This can improves the material utilization rate, simply the manufacturing procedures, and save material and processing time.
  • Petroleum cracking tube can be used for producing rolled bearing ring and lifting jack kit.
  • This seamless pipe is also an inevitable material in conventional weapons. We can use petroleum cracking pipes to produce gun barrels.
  • According to the shape of cross sectional area, it can be divided into round pipe and special pipe. On the premise of same perimeter, round petroleum cracking tube can convey more fluid.
