High precision cold drawn tube
當前位置:首頁 > Product Center > High precision cold drawn tube >
high-precision cold-drawn pipe (precision drawn pipe) is a high-precision steel pipe material that uses cold-drawn seamless pipe as raw material for tolerance control and surface brightening. Precision cold-drawn pipes have the characteristics of high precision, high smoothness, good inner wall cleanliness, steel pipes can withstand high pressure without leakage, cold bending without deformation, expansion, flattening without cracks, etc., and can be subjected to various complex deformations and mechanical processing. The chemical composition of precision cold drawn tubes is carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, and chromium Cr.
high-precision cold-drawn tubes are mainly used for automobiles, motorcycles, refrigeration equipment, hydraulic parts, bearings, pneumatic cylinders, and other customers who have high requirements for steel tube accuracy, smoothness, cleanliness, and mechanical performance.
The difference between high-precision cold drawn tube and cold drawn tube:
1. The main feature of ordinary seamless steel pipes is that they have no welding seams and can withstand greater pressure. Products can be rough cast or cold drawn parts.
2. Precision cold-drawn pipes mainly have strict tolerances and roughness on the inner hole and outer wall dimensions, and have high precision.
