Buttweld Fitting ASTM A815 S32750 Equal Tee Elbow Conc. Reducer
B16.9
YUHONG 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.
