B16.9 Buttweld Fitting ASTM A815 S32750 Equal Tee Elbow Conc. Reducer
YUHONG GROUP is engaged in manufacturing of a wide range of Butt
Weld Fitting that is available in varied types such as L/R &
S/R elbow, tee, concentric and eccentric reducers, reducing elbow
& tee, cross and caps.
Sourced from reliable vendors, these fittings are highly
acknowledged for their high tensile strength, durability and
accurate alloy composition. These find application in several
industries such oil & gas, automobile, acid & chemical,
pharmaceutical and cement industries. We are known for our butt
welding fitting pieces.
ASTM A815 covers two general classes, WP and CR, of wrought
ferritic, ferritic/austenitic, and martensitic stainless steel
fittings of seamless and welded construction. Class WP fittings are
subdivided into four subclasses: Classes WP-S, WP-W, WP-WX, and
WP-WU. The material for fittings shall consist of forgings, bars,
plates, or seamless or welded tubular products.
The steel shall be melted by electric furnace, vacuum furnace, or
electric furnace followed by vacuum or electroslag-consumable
remelting. Forging or shaping operations shall be performed by
hammering, pressing, piercing, extruding, upsetting, rolling,
bending, fusion welding, machining or by combination of two or more
of these operations.
