1. What are the advantages of Butt Weld Fittings over Flanges?...

    - Flanges connect pipes by bolting them together, whereas butt weld fittings connect pipes by welding them together. - Depending on size, butt weld fittings require 10% to 75% less material than a flanged connection, which means lower material cost and lower weight. - Welded construction permits greater freedom in designing a layout; this system uses less space, is more compact, and has greater strength. - Butt weld fittings provide optimum flow characteristics, without pockets or sharp corners, creating less frictional resistance, no pressure loss, less turbulence, …

  2. What is a Butt Weld Fitting...?

    - 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. - 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. - Other types of fittings can be threaded or socket welded. - They are essentially made from a piece of pipe, cut to length, heated and bend using various techniques.
