      Function: Widely used in manufacturing structural and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffolding used in construction, etc. Manufacturing annular parts with petroleum cracking tubes can improve material utilization rate, simplify manufacturing process, save material and processing time, such as rolling bearing rings, Jack sleeves, etc. At present, steel tubes have been widely used in manufacturing. Petroleum cracking tubes are also indispensable materials for all kinds of conventional weapons. Gun barrels, barrels and so on need to be made of petroleum cracking tubes. Petroleum cracking pipes can be divided into circular pipes and special-shaped pipes according to the shape of cross-sectional area. Because the oil cracking pipe has the largest area under the condition of equal circumference, more fluid can be transported by circular pipe.
