Pipe fittings are core components of building and industrial piping systems, employing innovative machining processes to replace traditional casting methods. Through steel ball stretching technology, precise forming from elliptical holes to standard circular holes is achieved (major axis 44-46 mm/minor axis 20-22 mm, steel ball diameter 49-50 mm). Combined with welding processes, complex structures such as tees, crosses, and five-way fittings can be formed.
The main structure includes a regular polygonal mounting section (such as a regular hexagon) and a planar connection section design. Some models integrate locking blocks, spring limiting devices, and filter backflow prevention components. The products combine high compressive strength (due to the superior crack resistance of the steel pipe substrate), recyclability (increasing material utilization by 20%-30%), and quick assembly/disassembly (using a rotating threaded pin to control the tightness of the connection).
