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.

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.

Alloy 41 has exceptionally high strength at temperatures in the range of 1200 to 1800°F (649 to 982°C). The alloy is a precipitation-hardening type and strength is developed by various solution annealing and aging heat treatments. In the annealed condition, the alloy is ductile and has essentially the same forming characteristics as 18-8 stainless steel and other nickel-based alloys. It is stronger, however, and has a greater resistance to forming. The alloy has been formed with success on drop hammers, expanding mandrels and stretch former.

Alloy 80A is a wrought, age-hardenable nickel-chromium alloy, strengthened by additions of titanium, aluminum and carbon, developed for service at temperatures up to 815°C (1500°F).
