The rate of these Alloy Steel WP9 Elbow Butt Weld Pipe Fittings increases with increases in the sulphur dioxide content of the atmosphere (such as might occur in industrial areas). In pure un – aerated acid, corrosion rates of Alloy Steel WP9 Equal Tee are low for all concentrations at atmospheric temperatures. In hot or concentrated solutions, rates of these Alloy Steel WP9 Cross Butt Weld Pipe Fittings are usually too high for reasonable service life. The salts in Alloy Steel WP9 Reducermay develop when hydrochloric acid comes in contact with iron and copper.

Alloy Steel WP9 End Cap Butt Weld Pipe Fittings can be welded by all common welding techniques, although oxyacetylene and submerged arc welding processes are not recommended when the fabricated item is to be used in corrosive service.
