Product Description

Product Description

Zhengde Precision steel pipe is a key material used in manufacturing high-precision and high-performance mechanical equipment. It has excellent physical and mechanical properties and is widely used in aerospace, automobile manufacturing, petrochemical and other fields.
 Material characteristics: 1. High precision: Precision steel pipes have high diameter accuracy and wall thickness accuracy, and can meet the accuracy requirements of various mechanical equipment. 2. Excellent mechanical properties 3. Good corrosion resistance 4. Excellent processing performance
 Production process: The production process of precision steel pipes mainly includes steps such as cold drawing, cold rolling and cold extrusion.
1. Cold drawing: The most common production process of precision steel pipes is cold drawing, which means cold processing of hot-rolled steel pipes, and drawing them to make the diameter and wall thickness meet the requirements.
2. Cold rolling: The cold rolling process is to cold process the hot-rolled steel billet. Through multiple passes of rolling and drawing, the size of the steel pipe is gradu.
 Application fields
Precision steel pipes are widely used in aerospace, automobile manufacturing, petrochemical and other fields, with the following typical applications:
1. Aerospace field: Precision steel pipes are used to manufacture high-pressure, high-temperature hydraulic systems and gas systems such as aircraft engines, missiles and rockets.
2. Automobile manufacturing field: Precision steel pipes are used to manufacture key components such as automobile chassis, engines and transmissions to improve the safety and reliability of automobiles.
3. Petrochemical industry: Precision steel pipes are used in oil and natural gas extraction and transportation pipelines. They have the characteristics of high pressure resistance and corrosion resistance to ensure the safe operation of petrochemical equipment.
4. Machinery manufacturing field: Precision steel pipes are used to manufacture various precision instruments, meters and mechanical parts, such as high-precision bearings, instrument cases, etc.ally adjusted and controlled.
3. Cold extrusion: The cold extrusion process is to heat the steel billet to an appropriate temperature and then extrude it through a special die to form a hollow pipe. The cold extrusion process can produce precision steel pipes with uniform wall thickness and high internal and external surface finish.
