JIS G3461 STB42 Petroleum Cracking Seamless Steel Pipe

JIS G3461 STB42 Petroleum Cracking Seamless Steel Pipe.Petroleum cracking Seamless Steel Pipe is a kind of long steel with hollow section and no joint around. Petroleum cracking pipes is a kind of economic section steel. It is widely used to manufacture structural parts and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffold used in construction. The manufacture of annular parts with petroleum cracking pipe can improve the utilization rate of materials, simplify the manufacturing process, and save materials and processing hours, such as rolling bearing ring, jack sleeve, etc. at present, steel pipe has been widely used to manufacture. Petroleum cracking tube is also an indispensable material for all kinds of conventional weapons. The barrel and barrel should be made of petroleum cracking tube. According to different cross-sectional area and shape, petroleum cracking pipe can be divided into round pipe and special-shaped pipe. Because the area of petroleum cracking pipe is the largest under the condition of equal circumference, more fluid can be transported with circular pipe.

1. The main production process of hot-rolled seamless steel pipe (main inspection process):
Tube blank preparation and inspection→tube blank heating→piercing→tube rolling→steel reheating→fixed (reduced) diameter→heat treatment △→finished tube straightening→finishing→inspection (non-destructive, physical and chemical, Taiwan inspection)→warehousing
2. The main production process of cold-rolled (drawn) Seamless Steel Pipes:
Billet preparation→pickling lubrication→cold rolling (drawing)→heat treatment→straightening→finishing→inspection

Our products aye widely used in water engineering,petrochemical industry,chemical industry,electric power industry,agricultural irrigation,urban construction.

Used for liquid conveying:water supply and drainage.For gas transport:gas,steam,liquefier petroleum gas.

For structural use:as pile pipe,as a bridge;Pipes for wharves,roads and building structures.
