Buttweld Fitting ASTM A815 S32750 Equal Tee Elbow Conc. Reducer B16.9
TONG CHUANG GROUP specializes in the manufacturing of a wide range of Butt Weld Fittings， including various types such as L/R and S/R elbows， tees， concentric and eccentric reducers， reducing elbows and tees， crosses， and caps. These fittings are sourced from reliable vendors and are highly regarded for their exceptional tensile strength， durability， and precise alloy composition. They are extensively used in industries such as oil and gas， automotive， chemical， pharmaceutical， and cement.
ASTM A815 encompasses two main classes， WP and CR， of stainless steel fittings made of wrought ferritic， ferritic/austenitic， and martensitic materials， available in both seamless and welded construction. Class WP fittings are further divided into four subclasses: WP-S， WP-W， WP-WX， and WP-WU. The fittings can be made from forgings， bars， plates， or seamless/welded tubular products.
The steel used for these fittings is melted using electric furnaces， vacuum furnaces， or electric furnaces followed by vacuum or electroslag-consumable remelting. Forging or shaping operations can be carried out through methods such as hammering， pressing， piercing， extruding， upsetting， rolling， bending， fusion welding， machining， or a combination of two or more of these techniques.
