Butt weld fitting

　　A butt weld fitting is two pieces of materials butted against each other and welded. Several different methods exist for beveling the two pieces for good weld penetration. Both flat stock and pipe or tubing can be butt welded. Generally, the weld is ground flush with the material surface.

　　Socket weld fitting:

　　A socket weld fitting involves two different sized pieces of pipe. The smaller one is inside the larger pipe. The weld is completely around the outside circumference of the larger pipe.

　　A Socket Weld fitting is a pipe attachment detail in which a pipe is inserted into a recessed area of a Valve, fitting or flange. In contrast to butt weld fitting, socket weld fitting is mainly used for small pipe diameters (Small Bore Piping); generally for piping whose nominal diameter is NPS 2 or smaller.

　　To join pipe to Valves and fittings or to other sections of pipe, fillet-type seal welds be used. Socket-welded Joints construction is a good choice wherever the benefits of high leakage integrity and great structural strength are important design considerations.

　　We are capable of manufacturing various pipe fittings. Our main products scope: api5l erw pipe and oil casing. We have been in this line for over 20 years. Our products are exported to many countries and regions, such as Southeast Asia, the Middle East, Europe and America etc.
