Butt weld fittings is one of the most popular connection type in pipeline systems. It always been required in large quantities in different industries, and especially for the large diameter pipelines. What is Butt Weld FittingsButt weld is to connect pipes or fittings ends by welding. It’s a weldable steel pipe fitting that would allow to branch off, allow for change of direction of flow, attach auxiliary equipment, or reduce the size of the pipe. We aware the beveling is very important processes in the whole production procession of butt-welding pipe fittings, we always make beveling according to the standard … Continue reading Weld beveling for flange and fitting
The socket weld is a pipe attachment detail in which a pipe is inserted into a recessed area of a valve, fitting, or flange. The joint construction is a good choice wherever the benefits of high leakage integrity and great structural strength are important design considerations. Advantages of Socket Weld Pipe Fittings The socket weld pipe fittings can be used in place of threaded fittings, so the risk of leakage is much smaller. Socket weld pipe need not be beveled for weld preparation. The weld metal can not penetrate into the bore of the pipe. Construction costs are lower than with butt-welded joints due … Continue reading Why is the Gap needed on Socket Welds
