How The Butt Weld Fittings Connect?
Butt weld fittings are designed to be welded to the pipes, creating a strong and leak-proof connection. The term "butt weld" refers to the type of welding used to attach the fittings to the pipes. This welding method involves two pieces of metal being placed together end-to-end and welded along the joint, resulting in a smooth, continuous connection.
Stainless steel 304/L Butt weld cap is used to mount at the pipe end by butt welding connection, so to block the pipeline and form liquid or gas tight seal.
Installed at the end of a pipe to block the flow. Stainless steel 304/L Butt weld cap is used for sealing or closing off the end of the pipe.
Standard Of Butt Weld Cap
The standard of butt weld cap is ASME/ANSI B16.9 which is also available for other butt weld fittings.
This standard covers the dimensions and the tolerances of carbon, alloy and stainless-steel butt weld fittings. It also covers all dimensions, tolerances, ratings, testing, and marking for factory-made.
ASME 16.9 Steel pipe caps are usually welded onto end of pipe that blcok off the piping line system, it has same funtion with plugs and blind flanges. It is available in material of carbon steel, stainless steel and alloy steel.
Butt weld cap dimensions is from 1/2" to 48" and thickness covers Sch 10S, Sch 40, Sch 80, Sch 160, STD, XS, XXS. We can manufacture Stainless steel 304/L Butt weld cap in stanadrd of ASME B16.9, MSS SP 43, DIN, JIS and EN.
ASTM A403 WP304L Stainless Steel Butt Weld Fittings
ASTM A403 WP304L stainless steel butt weld fittings is one of the most widely used steel fittings in the world for many reasons. WP304/304L is cheaper than most other stainless steel products and therefore is cost effective. It is an authenticate stainless steel and has chromium content in it. ASTM A403 WP304/L butt weld Fittings come under the standard ASME B16.9 and diameters ranging from 1/2 inches to 48 inches. The chemical has 18% chromium and 8% nickel in the composition and has good corrosion resistance and strength.
The ASTM A403 WP304/L material have high operating temperature range up to 870 degrees Celsius. So they can be used in high heat applications. The low carbon content in the material makes it better for welding applications. The A403 WP304/L butt weld cap is one of the many pipe fittings such as elbow,tee, reducer, and cross.Shanghai zhucheng is a large manufacturer and supplier of these stainless steel 304/L butt weld fittings.
