Titanium ASME SB-338 GR 7 Tube Boiler Wall Thickness 0.89mm Straight Tube Annealed
We supply seamless Grade 7 titanium alloy tubes for boiler and heat exchanger fabrication. Diameter 3/4 inch(19.05mm), with wall thickness 0.89mm, and the length in custom request. Round, straight, and annealed seamless tubes in titanium Gr7, with high quality and competitive price, meet the short time deadline. Grade 7/3.7235 Ti-Pd alloy(UNS R52400) is highly resistant to corrosion in reducing acids and localized attack in hot halide media.
The process properties and mechanical properties of Grade 7 titanium tubes are similar to those of industrial pure titanium tubing, but GR7 pipes are mostly used as transport pipelines for high-acid and high-corrosion liquids in the chemical industry. The addition of palladium improves the corrosion resistance in oxidizing media, especially the resistance to crevice corrosion. Therefore, Gr7 titanium tubes are widely used in hydrochloric acid, sulfuric acid, phosphoric acid, nitric acid, chloride corrosion media.

Gr7 Titanium Alloy Metal Material General Introduction
Ti-0.2Pd (Grade 7) Titanium alloy with addition of small quantities of precious metals palladium and pure industrial titanium The palladium of the alloy improves not only the corrosion resistance in reducing medium, but also its corrosion resistance in oxidizing medium. In high temperature and high concentration of various chloride media, Ti-0.2Pd alloy has the strongest anti-crevice corrosion resistance. Ti-0.2Pd has various properties similar to industrial pure titanium, so the alloy is widely used in chemical industry, especially petrochemical industry.
