Stainless Steel Breather Valves Manufacturer

The TIG welded tube (Tungsten Inert Gas welded) represents the highest quality welded tube, featuring precision welding with minimal heat input, narrow weld bead, excellent weld penetration, and superior mechanical properties approaching seamless tube performance. TIG welding produces clean, oxidation-free welds ideal for high-purity applications, pressure vessels, and critical service. ERW welded tubes (Electric Resistance Welded) utilize high-frequency electrical current to join tube edges through resistance heating, offering economical production with good strength and consistent quality for general industrial applications.

Laser welded tubes employ focused laser beam energy for welding, creating extremely narrow, precise weld seams with minimal heat-affected zones and exceptional weld quality. This advanced process enables manufacturing of small-diameter, thin-wall tubes with outstanding dimensional tolerances and surface finish. Plasma welded tubes use plasma arc technology for high-speed welding, combining quality with productivity for medium to large diameter tubes.

The sanitary welded tube (also called hygienic welded tube) features TIG welding with internal and external weld bead removal (scarfing), followed by bright annealing and electropolishing to achieve smooth, crevice-free surfaces meeting 3-A Sanitary Standards, ASME BPE, and FDA requirements. Bright annealed tubes undergo controlled atmosphere annealing producing shiny, oxide-free surfaces without additional pickling or polishing—ideal for pharmaceutical and food processing. Electropolished welded tubes receive electrochemical surface treatment removing surface material to achieve Ra values of 0.25-0.8 μm, enhancing corrosion resistance and cleanability.

Square welded tubes and rectangular welded tubes serve structural applications, architectural features, frames, and support systems. Capillary tubes (small diameter, thin wall) are used in instrumentation, heat exchangers, and medical devices. Additionally, SS 304 welded tubes provide excellent corrosion resistance for general industrial, architectural, and food processing applications at economical prices, while SS 316 welded tubes offer superior chemical resistance, pitting resistance, and chloride resistance for pharmaceutical, marine, and aggressive chemical environments due to their molybdenum content.
