- Precision pipe is the carbon, alloy or stainless steel pipe with high precision sizes. Usually it has been made through hot rolling or cold drawn (cold rolling) processes. The internal and external diameter could control within +/- 0.01 mm. In the guarantee of anti-bending strength and torque strength same, the weight of precision pipe is lighter.
- Because precision steel pipes have no oxide layer on the inner and outer walls, can withstand high pressures without leakage, have high precision, high smoothness, no deformation in cold bending, no cracks in flaring and flattening, etc., they are mainly used to produce products with pneumatic or hydraulic components, such as cylinders or Oil cylinder. |
- Implementation standards: DIN 2391, DIN2445, EN10305, DIN1630, DIN1629, ASTM A106, ASTM A179, JIS G3445, etc.
- Steel grade: 10#, 20#, 35, 45, 40Cr, 25Mn. 37Mn5, St35(E235), St37.4, St45(E255), St52(E355), etc.
- Application areas:
1. Automobile manufacturing field: Precision steel pipes play a very important role in automobile manufacturing. They are widely used in engine air intake, exhaust systems, fuel supply systems, etc. Because the precision steel pipe has a smooth surface and no oxide scale and burrs on the inner surface, it can effectively reduce energy loss and life loss, improve engine efficiency, and be more environmentally friendly.
2. High-precision machinery manufacturing field: Precision steel pipes are also widely used in high-precision machinery manufacturing fields. For example, processing equipment such as high-speed milling machines and machining centers require high-precision bearing systems. These bearings are typically made from precision steel tubing, which ensures the equipment can be machined quickly and accurately.
3. Aerospace field: In the aerospace field, precision steel pipes are also widely used. The high requirements for materials in the aerospace industry give precision steel pipes a huge advantage in this field. For example, in manufacturing engines for jet turbine aircraft, very precise materials and components are required to ensure engine performance and stability.
4. Petrochemical industry: In the petrochemical industry, precision steel pipes are also one of the indispensable materials. Refineries, fertilizer plants, etc. need to transport, store and process various chemical substances, and suitable pipelines have become the most important part of the system, including many types of precision pipes such as low-temperature wall thickness pipes and high-temperature alloy pipes. is widely used.
In addition, precision steel pipes are also widely used in other fields, such as pharmaceuticals, electronics, construction, electric power and other fields.
