Stainless Steel Precision Tube

Precision steel pipe is a high-precision steel pipe manufactured by cold drawing or hot rolling. Its dimensional accuracy, surface finish and mechanical properties are better than those of ordinary steel pipes. It is widely used in machinery, automobiles, aerospace, petrochemical and other fields.

Processing of our precision steel tubes

Production usually involves the following main steps:
1.Material selection: Select high-quality steel billets, whose chemical composition and mechanical properties must meet the quality requirements of precision steel tubes.
2.Heat treatment: According to different steel grades and uses, corresponding heat treatments such as annealing, normalizing, quenching, etc. are carried out to improve the organizational structure and mechanical properties of the steel tube.
3.Cold drawing or hot rolling: The cold drawing process can achieve higher precision and better surface quality, while the hot rolling process is more suitable for the production of large-diameter precision steel tubes.
4.Straightening: Straighten the steel tube to ensure that its straightness meets the requirements.
5.Surface treatment: Various surface treatments such as polishing, pickling, plating, etc. are carried out as needed to improve the corrosion resistance, wear resistance and appearance quality of the steel tube.
6.Inspection: The steel tube is strictly inspected to ensure that it meets various technical indicators.

Details of our precision steel tubes:

1. Dimensional accuracy: The dimensional accuracy of precision steel tubes is very high, and the tolerance is usually between ±0.01mm and ±0.05mm.
2. Surface roughness: The surface finish is high, and the Ra value is usually between 0.4μm and 1.6μm.
3. Straightness: Good straightness and small curvature.
4. Mechanical properties: Good strength, hardness, toughness and plasticity.

Sampling testing will be conducted on each batch of products.

Surface treatment of precision steel tubes:

Polishing: Make the surface bright and smooth to improve the appearance quality.
Wire drawing: Form a fine texture, beautiful and wear-resistant.
Sand blasting: Make the surface rough and increase friction.
Electroplating: Increase surface hardness and corrosion resistance.
Coating: Such as painting, plastic coating, etc., to improve corrosion resistance and wear resistance.

Materials of precision steel pipes:
The materials of precision steel pipes are varied, the most common ones are:
1.Carbon steel: has high strength and hardness, and relatively low cost.
2.Alloy steel: has higher strength, hardness, wear resistance and corrosion resistance.
3.Stainless steel: has excellent corrosion resistance.

Applications of precision steel pipes:

Precision steel pipes have a wide range of applications, for example:
Hydraulic system: used to make hydraulic cylinders, hydraulic pipelines, etc.
Pneumatic system: used to make pneumatic cylinders, pneumatic pipelines, etc.
Machinery manufacturing: used to make various mechanical parts.
Automobile industry: used to make automotive parts.
