Standard-Wall Butt-Weld Steel Unthreaded Pipe Fittings
Butt-weld fittings allow for a smooth connection that provides maximum flow. They have beveled ends that, when flush to pipe, create a trough for a strong, permanent weld. Fittings are also known as Schedule 40. They are for use in noncorrosive environments.

Butt Weld Pipe Fitting Bevel
All welded pipe fittings have bevelled ends to allow for ease of welding. This bevel allows for full penetration weld in most cases. There are two types of bevels;
Plain Bevel and Compound Bevel.
Buttweld Pipe Fitting Specification & Standards
Welded pipe fittings are made as per ASME spec B16.9. ASME B16.9 covers factory made wrought steel butwelding fittings in sizes 1/2" to 48". This standard however does not cover low pressure corrosion resistant buttwelding fittings. See MSS SP-43, Wrought Stainless Steel Butt-Welding Fittings.
Benefits of Butt Weld Pipe Fittings
●Welded connection offers a more robust connection
●Continuous metal structure adds to the strength of the piping system
●Buttweld fittings with matching pipe schedules, offers seamless flow inside the pipe. A full penetration weld and properly fitted LR 90 Elbow, Reducer, Concentric reducer etc. offers gradual transition via welded pipe fitting.
●Option of various turn radius using Short Radius (SR), Long Radius (LR) or 3R Elbows
●Cost effective compared to their expensive threaded or socket weld counter parts.
●Stainless Steel Welded Fittings are also available in SCH 10, allowing a more thinner wall option.
●Stainless Steel Butt Weld Fittings are more common in SCH 10 and SCH 40 configuration.
●Low cost from bulk production will reduce your budget and improve your business.
