Product Details

Small outer diameter precision steel pipe is with smaller diameter and high precision which small order quantity is allowed. The manufacturing technique is cold rolled or cold drawn which makes the surface of precision steel tube smooth and bright and the mechanical property is better. Based on those good qualities, small OD precision pipe can be used in making machines, hydraulic equipment, automobiles components, steel sleeve and bearings.

more details of product

Small size seamless precision steel pipe is produced by solid billet through inspection and clear surface defects cut into the required length then centering on the tube billet perforation end face and then sent to the furnace heating on the punching machine in perforated revolve and progress at the same time under the action of roll and head. The tube billet internal gradually formed cavity capillary then sent to plug mill continue rolling finally after all the machine all the whole wall thickness and the sizing machine to meet the specification requirements. The use of continuous rolling pipe unit production hot rolled the small diameter steel pipe is more advanced methods. If you would like to get a smaller size pipe and better quality of small diameter steel pipe then must adopt the method of cold rolling cold drawn or both combined cold rolling is usually conducted on two-high rolling mill. The small diameter precision steel tube is in variable cross section round hole groove and fixed cone in the head of the ring groove rolling. The cold drawing usually on a single or double chain cold drawing machine extrusion method is heated tube billet in airtight extrusion cylinder hole rods and extrusion then extrusion from smaller extrusion die. This method can produce smaller diameter of precision steel pipe.
The characteristics of small size precision steel pipe
1. The outer diameter is much smaller.
2. High precision to do small batch.
3. Cold drawn finished products of high precision, good surface quality.
4. The small size precision steel pipe transverse area is more complex.
5. Steel pipe is superior performance, dense metal.
6. Cold drawn finished products of high precision, good surface quality.
