Typical application key word :

Advantage of bright annealing precision tubes&pipes of TINSI-STEEL

1.More precise dimension

TINSI steel using the high quality industrial raw materials pipe produced by ourselves and advanced three-roller-precision-cold-rolling technology, making the close dimension controls.  tinsi-steel using precision rolling or precision draw processing repeatedly more times for high precision requirements tubes.so that tinsi tube more characterized by precise diameter tolerance ovality, eccentricity and controlled hardness for superior performance of precision systems.

2. Better mechanical property

TINSI using bright annealing method, the temperature of furnace can reach more than 1350℃, and the tolerance for the setting and real temperature can be controlled within +/-10℃, which is impossible for the traditional annealing.

3. Superior surface finish

The traditional annealing method is performed in a so called open furnace, where the atmospheric oxygen causes scaling of the heat treated materials, which makes the surface rough. We tinsi steel usually uses bright annealing process to produce stainless steel precision tubes,the heat treatment is performed in a so called closed furnace. The heat treated materials is protected by an inter gas atmosphere, which guarantees the oxygen cannot enter the furnace or come in to contact with the materials and react to form scale on or tarnish the materials. The surface finish is clean, bright and precision, which is an excellent starting point for further process, like electro-polishing and mechanical polishing.

4. Perfect inspection method and inspection equipment

TINSI more dimension test and strict quality control  in production,and ensure the quality to meet various requirements of each tube, we also more strict test such as PMI test, Hydraulic, inner cleaned by sponge, dimension test, and surface test.

What’s more, TINSI offer precision drawn tubing that the quality is similar to precision rolling, but has more advantage on price.

Bright annealing Irreplaceable application in stainless steel tubes&pipes of TINSI-STEEL

The surface finish is clean, bright and precision, which is an excellent starting point for further process, like electro-polishing and mechanical polishing.

Especially for the tube with length more than 12 meters, the traditional pickling tube is very hard to clean the inner surface, however, with the bright annealing method, the tubing is much cleaner, smoother on both inner and outer surfaces.And tinsi-steel also used for small diameter capillary and needle tube to ensure the inner hole is clean
