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.
