A Butt Weld Pipe Fitting is defined as a part used in a piping system, for changing direction, branching or for change of pipe diameter, and which is mechanically joined to the system. There are many different types of fittings and they are the same in all sizes and schedules as the pipe. Buttweld fittings are widely uses in the petroleum, smelting, foodstuff, power, papermaking, chemical, medical equipment, aviation, boiler heat exchanger, and other fields.

There are many different types of butt weld fittings. We offer all of the most varieties, including the following:

• Bend, End Cap, Coupling, Elbow, Nipple, Branch Outlets, Reducer, Stub Ends, Tee, 45 Elbow, Reducing Elbow, Reducing Tee, Barred Tees, 90 Elbow LR & SR, Concentric Reducer, Eccentric Reducer, 180 Return Bend, 3R & 5R Bends, Cross, Lateral, Reducing Lateral, Swage Nipple

Advantage of Using Buttweld Fittings

• Buttweld fittings allow strong, and leak-proof, piping connections
• They minimize pressure drops and the turbulence inside the pipeline
• These type of fittings have a long service life
• Butt weld pipe fittings are low cost alternative to forged fittings and are more easy to deploy

Stainless steel 304(SS304) is the most basic stainless steel known as 18-8 grade with higher chromium and low carbon content. The low carbon content restricts carbide precipitation during welding as well as minimizes its susceptibility to intergranular corrosion. Stainless steel 304L(SS304L) is an extra low-carbon variation of SS304 with a 0.03% maximum carbon content that eliminates carbide precipitation due to welding. Both SS304 and SS304L have excellent resistance to a wide range of atmospheric, chemical and petrochemical, and food industry corrosions. Usually, they can be used in applications with the maximum temperature of 1650°F[900°C] exhibiting good oxidation resistance.

304L alloy’s lower carbon content helps minimize/eliminate carbide precipitation during the welding process. This allows 304L stainless steel to be used in the “as-welded” state, even in severe corrosive environments.

If you were to use standard 304 stainless in the same way, it would degrade much faster at the weld joints.

Basically, using 304L eliminates the need to anneal weld joints prior to using the completed metal form—saving time and effort.

In practice, both 304 and 304L can be used for many of the same applications. The differences are often minor enough that one isn’t considered massively more useful over the other. When stronger corrosion resistance is needed, other alloys, such as grade 316 stainless steel, are usually considered as an alternative.
