FLEXIBLE STAINLESS STAINLESS PIPE FOR FLARING 12 MM * (1/2 ")

Corrugated stainless pipes 12 mm for flaring with a manual flare tool for the manufacture of bellows connections with union nuts of any length, which can be used to connect water, steam and gas.

To create a connecting element, you need to put a union nut of a suitable size on the corrugated pipe and flare the first three annular corrugations on the stainless pipe using a roller. The edges of the corrugated pipe should be flat and directed slightly inward in a circle. After rolling, you should get a flat round platform on which any round gasket will fit to seal the connection.

The most used corrugated stainless pipe 12 mm for the manufacture of flexible hoses connection 1/2 nut - nut is sold in coils of 20, 40, 60, 80 meters, the pipe can be either annealed or unannealed.

To create a connecting element, you need to put a union nut of a suitable size on the corrugated pipe and flare the first three annular corrugations on the stainless pipe using a roller. The edges of the corrugated pipe should be flat and directed slightly inward in a circle. After rolling, you should get a flat round platform on which any round gasket will fit to seal the connection.

With such a manual roller, bellows liners can be made from three sizes of corrugated pipes 12 mm, 18 mm, 20 mm, each size will need its own roller.

 Flexible pipes of a bellows type with union nuts, sizes ½, ¾, 1 inches, made of corrugated pipes with a straight through diameter of 12 mm, 18 mm, 20 mm with a manual reel. Corrugated pipes are well suited for connecting water and heating equipment. They are designed for an operating pressure of 15 bar and an operating temperature of up to +250 degrees, depending on the gaskets.
