BACKPrecision seamless steel pipe
Cold-drawn precision steel pipe
Description:Cold drawing process: Cold drawing is the core of cold drawing precision pipe production. In the low temperature state of the steel pipe, the steel pipe is continuously stretched through the mold to further reduce the size of the steel pipe and improve the precision and surface finish of the steel pipe. During the cold drawing process, it is necessary to precisely control the tension, speed and temperature parameters of the cold drawing machine to ensure that the steel pipe is gradually deformed under uniform stress without cracks or defects.
parameters
Domestic main implementation standards
GB/T 3639: This standard specifies in detail the size, shape, weight and allowable deviation of cold-drawn or cold-rolled precision seamless steel pipes, technical requirements, test methods, inspection rules, packaging, marking and quality certificates. It is suitable for mechanical and structural components with high requirements for steel tube accuracy and surface quality. In addition, the standard also pays special attention to the inner diameter accuracy and roundness of the steel pipe to ensure its application performance in hydraulic and pneumatic systems.
Second, the main implementation of foreign standards
EN 10305: This series of standards consists of several parts, each for different types and applications of precision steel pipe detailed regulations. Among them, EN 10305-1 stipulates the technical delivery conditions of cold-drawn seamless steel pipes; EN 10305-2 specifies the technical delivery conditions for cold-drawn welded steel pipes; EN 10305-4 specifically specifies the technical conditions for the delivery of cold-drawn seamless steel pipes for hydraulic pneumatic systems.
