BACKPrecision seamless steel pipe
Precision steel pipe manufacturers
Description:Precision steel pipe is a kind of high precision steel pipe material after cold drawing or hot rolling, which has high dimensional accuracy, high finish and excellent mechanical properties.
Precision steel pipes are widely used in automobile manufacturing, high-precision machinery manufacturing, aerospace, petrochemical, power, food and health and other industries.
parameters
Product characteristics
high precision : there is no oxide layer in the inner and outer walls, and the dimensional accuracy is high.
high finish : high surface finish inside and outside the tube, no oxide film.
Excellent mechanical properties : can withstand high pressure, cold bending without deformation, flaring and flattening without cracks.
Wide application field : suitable for many industrial fields to meet different needs.
introduction
Production technology
raw material preparation : high quality billet is selected as raw material to ensure that the chemical composition and mechanical properties of the steel pipe meet the standard.
heating and perforating : the billet is heated to the appropriate temperature and pierced through the perforator into a hollow tube.
rolling : The tube is sent to the rolling mill for multiple passes, and the outer diameter, inner diameter and wall thickness are precisely controlled.
finishing : including straightening, cutting, grinding and other steps to improve the dimensional accuracy and surface quality of the steel pipe.
Heat treatment : such as annealing, normalizing, etc., to eliminate internal stress, improve structure and improve performance.
Inspection and packing : After strict inspection, the qualified products will be packed and shipped.
