Bright Annealed Tubes

Bright Annealed Tubes Description

The traditional annealing approach is performed in a so referred to as open furnace, where the atmospheric oxygen reasons scaling of the heat treated materials, which makes the surface rough. HUASHANG STEEL has developed a one of a kind bright annealing process, the heat treatment is carried out in a so-called clsoed furnace. The warmth handled materials is covered by means of an inter-fuel atmosphere, which ensures the oxygen cant enter the furance or come in to contact with the substances and react to shape scale on or tarnish the materials. The surfaceend is clean, bright and precision, which is a top-notch beginning point for similarly system, like electro-polishing and mechanical polishing.

Especially for the tube with size greater than 12 meters, the ordinary pickling tube is very hard to clean the internal surface, however, with the bright annealing method, ourbright annealed stainless steel tubingis much cleaner, smoother on both inner and outer surface. We,pipe fittings manufacturers in chinause bright annealing method, the temperature of furnace can reach greater than 1350℃, and the tolerance for the putting and real temperature can be controlled Within ±2℃, which is not possible for the regular annealing To ensure the quality, all tubes are done 100% PMI, 100% Hydraulic test, 100% inner cleaned by sponge, 100% dimension test, and 100% surface test.

What is more, our quality of precision drawn tubing is same to precision rolling but has more advantage on price? We are using the advanced cold drawn technology from Japan and Korean, making the close dimension controls Huashang steel tubing used for instrument tubing, chromatography tubing, hydraulic tubing, high-pressure tubing, cleaned tubing, multi-core tubing. Type of tubes is welded tubing and seamless tubing.

Straight Tubes Bright Annealed Tube Advantages

1. Superior Surface Finish
2. Better Mechanical Property
3. More Precise Dimension
