Projects
Many years of large-scale project experience in various fields（Oil & Gas, Construction, Power Energy, Marine & Offshore, Water Treatment, Exploration & Drilling Services, Pipeline & Petrochemical etc.）, professional project team is responsible from receiving until the end of the project.
Precision steel pipe is a kind of seamless steel pipe material with high precision inside and outside bright after cold rolling treatment. Because there is no oxide layer on the inner and outer walls of the precision steel pipe, no leakage of high-level bearing, high precision, high smoothness, cold bending without deformation, flaring, flattening without cracks, etc., it can be done after the final annealing. So it is mainly used for production startup or hydraulic Component products, such as cylinders or oil cylinders, can be
Process characteristics of precision steel pipes: high-quality carbon steel, finish rolling, non-oxidizing bright heat treatment (NBK state), non-destructive testing, the inner wall of the steel pipe is brushed with special equipment and subjected to high-pressure washing, the steel pipe is treated with rust-proof oil for rust prevention, and both ends are sealed Make dustproof treatment.
Features: The inner and outer walls of the steel pipe have high precision and high smoothness. The steel pipe has no oxide layer after heat treatment. The inner wall has high cleanliness. The steel pipe bears high pressure, cold bending does not deform, flaring and flattening without cracks, and can be subjected to various complex deformations and mechanical processing. The color of the steel pipe: the amount of white belt, with high metallic luster.
The main purpose of precision steel pipes: precision steel pipes are widely used in automobiles, motorcycles, electric vehicles, petrochemicals, electric power, ships, aerospace, bearings, pneumatic components, seamless steel tubes for medium and low pressure boilers, etc., and can also be applied to steel sleeves and bearings , Hydraulics, machining (seamless mechanical steel tube) and other fields.
Main standards: DIN2391, DIN2445, EN10305, DIN1629, DIN1630, ASTM A179
Main material of precision steel pipe: ST35 (E235), ST37, 4ST459 (E255), ST52 (E355)
Main delivery status: NBK (+N), GBK (+A), BK (+C), BKW (+LC, BKS (+SR)
