Shanghai Metal Corporation is a leading stainless steel capillary tube manufacturer and supplier.

Stainless steel capillary use: automatic instrument signal tube, automatic instrument wire protection tube; precision optical ruler line, industrial sensor, electronic equipment line protection tube; electrical line safety protection, thermal instrument capillary protection and internal support of air core high-voltage cable.

Stainless steel capillary characteristics: It has good softness, corrosion resistance, high temperature resistance, abrasion resistance, tensile strength, water resistance and excellent electromagnetic shielding performance. Stainless steel hoses can be bent freely into various angles and radii of curvature, with the same flexibility and durability in all directions; flexible between stainless steel hose pitches, good flexibility, no clogging and stiffness The stainless steel threading hose has a certain tensile force between the side buckles, so as to prevent the damage of the hose, the line laid inside the hose is exposed, and the axial tensile force can withstand more than 6 times of the nominal inner diameter.

Q: Can you do polished finish for the tubes/pipes?

A: Yes, for welded tubes/pipes, we can do mirror polishing, 600# polishing, 500# polishing, 320# polishing, 240# polishing and so on, brushed finish is also available. For seamless tubes/pipes, normally the surface is pickled finish, while brushed finish is also doable.

Q: What’s your standard package?

A: Our standard package is waterproof plastic bags with wraps. For advanced packing, we can provide round paper tube for each tube, and wooden/metal case for exterior packing.

Q: Where’s your main market?

A: South America, Mid-east, South-east Asia, Europe and so on.

Q: Do you also have the accessories for the tubes?

A: Yes we can provide the accessories too.

Q: What length is your standard length? Can I have the tubes/pipes cut into the length I want?

A: Our standard length is 3meter, 4meter, 5meter, 6meter. If you length is less than 3meter, we will have to run an additional processing for cutting which will bring some more costs. The minimum length is 500mm. For seamless tubes, we can make maximum to 12, 13meters.
