Butt weld pipe fittings allow for changing the direction of flow, reducing pipe sizes and attaching auxiliary equipment.

A common example using welded pipe fitting is a pipe reduced by concentric reducer, welded to a weld neck flange and connected to an equipment. Figure below represent complete collection of butt welded pipe fitting

• 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.

All butt weld fittings have beveled ends as per ASME B16.25 standard. This helps create full penetration weld without any extra preparation needed for the butt weld fitting.

Butt weld pipe fittings are most commonly available in carbon steel, stainless steel, nickel alloy, aluminum and high yield material. High yield butt weld carbon steel pipe fittings are available in A234-WPB, A234-WPC, A420-WPL6, Y-52, Y-60, Y-65, Y-70.  All WPL6 pipe fittings are annealed and are NACE MR0157 and NACE MR0103 compatible.

Steel pipe fittings advantages

The quality of raw materials is good, the quality of finished products is superior; Shenlong steel pipe fittings are 100% non-destructive testing, short delivery time and can be set according to the drawings.The customerized quantity(even one piece) can be mostly satisfied.

Steel pipe fittings quality inspection:

1. Our factory has its own "experimental testing center".CNAS Laboratory Accreditation Certificate

2.Control quality strictly.The first pass is the quality inspection on the production line,The second pass is full inspection of the  production quality .

3.We have got internationally recognized certificates, ISO, CE, LR,Philippine certificate,also support third-party testing,as SGS, BV, etc.
