Petroleum cracking pipe

Implementation standard and introduction of petroleum cracking pipe:

Seamless steel pipe for petroleum cracking pipe (GB9948-2006, non-equivalent to ISO 9329/2:1997)

This standard is applicable to petrochemical boiler tube, heat exchanger tube and pressure pipe special seamless steel pipe.

The seamless steel tubes of this standard are divided into two categories according to the manufacturing method of the products. The categories and codes are:

Hot rolled (extruded, expanded) steel tube WH;

WC cold drawn (tied) steel pipe.

Steel grades

10, 20, 15CrMo, 1Cr2Mo, 1Cr5Mo, etc

The delivery status

10 and 20 & lt; Hot rolled pipe final rolling, cold drawn pipe normalizing >

15CrMo< Hot rolled tube final rolling + tempering, cold drawn tube normalizing + tempering >

1Cr2Mo< Hot rolled tube final rolling + tempering, cold drawn tube normalizing + tempering >

1Cr5Mo< Annealing & gt;

Weight calculation formula: common carbon tube: (outer diameter - wall thickness) X wall thickness X0.02466=KG/M

Alloy tube: (OD - wall thickness) X wall thickness X0.02486=KG/M

advantage

1, with the petroleum cracking pipe manufacturing ring parts, can improve the material utilization rate, simplify the manufacturing process, save materials and processing time, such as rolling bearing ring, jack cover, etc., has been widely used in steel pipe manufacturing.

2, petroleum cracking pipe or all kinds of conventional weapons indispensable materials, gun barrel, barrel, etc., to make petroleum cracking pipe. The petroleum cracking pipe can be divided into round pipe and special-shaped pipe according to the different shape of cross-sectional area. Since the area of the oil cracking pipe is the largest when the circumference is equal, more fluid can be transported with the circular pipe.

USE

It is widely used in manufacturing structural parts and mechanical parts, such as oil drill pipe, automobile drive shaft, bicycle frame and steel scaffolding used in construction, etc.

Suitable for oil, refinery furnace tube, heat exchanger tube and pipe seamless steel pipe.
