Butt welding is a technique which is mainly used to connect parts which don’t overlap and are nearly parallel. Butt welding is economical and reliable way for joining pipes together done by gradually heating up the two weld ends with a weld plate under a specific pressure. This process is very suitable for prefabrication and producing special pipe fittings products. Butt weld fittings connect pipes by welding them together to provide them greater strength and compatibility to allow change in direction or pipe diameter, branching or ending to cover long and short distances.

A buttweld fitting is a weldable pipe fitting that allows for change of direction of flow, to branch off, reduce pipe size or attach auxiliary equipment. Forged Steel buttweld fittings are manufactured in accordance with ANSI / ASME B16.9.

Butt Weld Fitting Cheat Sheet

1) Client calls butt weld fittings in A105:

Most regular carbon steel buttweld fitting material is A234WPB. It is identical to A105 spines, however there is no such thing as A105 or A106 butt weld fitting

2) Client asks for "Standardized" butt weld fittings:

This is also a misconception since flanges are accessible in A105 and A105 N, where N remains for standardized. However, there is no such thing as A234WPBN. A few manufacturers standardize their butt weld fittings as a standard system and such demand require checking singular material test testaments to confirm if standardized heat treating procedure was finished. Client requiring "standardized" butt weld fittings should request WPL6 fittings which are high yield and are standardized as a standard strategy

3) Client forgets to specify pipe plan:

Buttweld fittings are sold according to pipe measure yet pipe size must be indicated to coordinate the ID of the fitting to the ID of the pipe. On the off chance If no schedule is mentioned, we will assume a standard wall is requested.

4) Difference between True Schedule 40 and SCH 40:

Pipe fittings 12 inch or bigger require indicating if fitting is standard wall (most normally referred to sch 40) or a genuine schedule 40 is required. This is required since schedule 40 don't compare to standard wall for pipe sizes 12" and greater. A genuine sch 40 will be thicker than standard wall for pipe fittings 12" or greater.

5) Difference between SCH 80 and True Schedule 80:

For pipe sizes 10 in or more, sch 80 don't compare to XH. Client must indicate in the event that they need SCH 80 or XH wall.

Stainless Steel buttweld pipe fittings are accessible in schedule 10s: Customer ought to determine in the event that they require standard wall (sch 40s) or a more slender or thinner wall sch 10s stainless steel butt weld fitting.

6) Client neglect to say welded or seamless butt weld fitting:

Butt weld fittings are accessible in both welded and seamless arrangement. A seamless butt weld carbon steel or stainless steel fitting is made of seamless pipe and is by and large more costs. Seamless pipe fitting is NOT basic in sizes greater than 12". Welded pipe fittings are made of ERW welded carbon steel or stainless steel pipe. They are available in sizes ½" to 72" and are more affordable than seamless fittings

7) What does Short Radius (SR) or Long Radius (LR) implies?

You will regularly hear SR45 elbow or LR45 elbow. The 45 or 90 angle to the point of the twist for buttweld fitting to alter or change the direction of flow. A long radius elbow (LR 90 Elbow or LR 45 elbow) will have a pipe curve that will be 1.5 times the size of the pipe. In this way, a 6 inch LR 90 has bowing or bending range that is 1.5 x ostensible (nominal) pipe size. A short radius elbow (SR45 or SR90) has pipe twist that is equivalent to the measure of fitting so a 6" SR 45 has bowing range that is 6" ostensible pipe size.

8) What is a 3R or 3D elbow pipe fitting?:

First, the term 3R or 3D are utilized synonymously. A 3R butt weld elbow has bending radius that is 3 times the ostensible pipe estimate. A 3R elbow is smoother than SR or LR fitting.
