6 Inch Schedule 40 304 , 304L , 316 , 316L Weld Fittings Tees ASME/ANSI B16.9
Buttweld 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. Buttweld fittings is a butt-welded connected pipe fittings, it is easy for installation and maintenance. There are many different types of fittings and they are the same in all sizes and schedules as the pipe.
Buttweld fittings (BW fittings) whose dimensions, dimensional tolerances et cetera are defined in the ASME B16.9 standards. Light-weight corrosion resistant fittings are made to MSS SP43.
Description:
1. Stainless steel elbow and stainless steel tee is the most important butt weld pipe fittings, they are fabricated by seamless stainless steel pipes or steel plate and get beveled end for butt-welding.
2. A butt weld pipe fitting is designed to be welded on site at its end(s) to connect pipe(s) together and allow change in direction or pipe diameter, or branching or ending.
3. This fitting then becomes part of a system for transporting fluids (oil, gas, steam, chemicals, …) in a safe and efficient manner, over short or long distances.
