Precision Capillary Seamless Tube

Capillary tube is a special, precise and high-quality round metal tube made by fine rolling and fine drawing.

It usually refers to the tube under OD6.0mm.

It is divided into capillary seamless tube and capillary welded and cold drawn tube.

Generally speaking, compared with welding cold-drawn tube, capillary seamless tube has higher and stricter requirements on manufacturing conditions, process, detection, inspection, performance, shape and dimensional accuracy control, and is more suitable for high-end, precision and harsh conditions of the application.

Ultra Thin Wall Seamless Tube

Thin wall & ultra thin wall seamless tube refer to the ratio of wall thickness and outer diameter less than 6% seamless tube.

They are generally formed by intermediate annealing and multi-pass cold rolling of two or three high mills.

Small outer diameter can be obtained by reducing the wall drawing process.

According to customer's special surface requirements, the tubes can be polished by different processes.

Micro ID Thick Wall Seamless Tube

Micro ID thick wall seamless tube is a small caliber non-standard tube.

It is generally made by finishing rolling, fine drawing or other special processes, with distinctive features of high bearing capacity and high strength, suitable for gas transmission, oil transmission or other special purposes which usually have high internal pressure and high strength.

Precision Conical Seamless Tube

At present, most of the conical tubes on the market are welded tube, heat expansion tube or extruded tube.

Welded conical tube is made by CNC precision cutting and cold pressing of metal sheet.

Seamless conical steel pipe is a conical hollow round pipe with different diameters at both ends made of seamless steel pipe as raw material.
