The manufacturing process of seamless steel pipe is relatively complex, but it has excellent physical properties and good processing performance, so it occupies an important position in the oil, natural gas and other industries. Seamless pipes on the market can be divided into two categories: hot-rolled seamless pipes and cold-drawn seamless pipes. The manufacturing process of the former is to heat the steel to a certain temperature and then punch it through a punch; the latter is made by changing the hole shape. Since the process is slightly complicated, the price is relatively expensive.
Petroleum seamless pipe is a long steel material with a hollow cross-section and no seams around it. Petroleum cracking pipe is an economical cross-section steel material.
It is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile drive shafts, bicycle frames, and steel scaffolding used in construction mobile pictures. Using petroleum cracking pipes to manufacture ring-shaped parts can improve material utilization, simplify the manufacturing process, save materials and processing hours, such as rolling bearing rings, jack sets, etc., which have been widely manufactured with steel pipes. Petroleum cracked tubes are also an indispensable material for various conventional weapons. Gun barrels, barrels, etc. are all made of petroleum cracked tubes. Petroleum cracking pipes can be divided into round pipes and special-shaped pipes according to their cross-sectional area shapes. Since the area of petroleum cracking tubes is large under the condition that the circumferences are equal, circular tubes can transport more fluid.
