Instead of pipe groove processing, the ring is welded to enable stronger fastening of large-diameter pipes.
It is a product that welds rings instead of pipe grooves to allow stronger fastening of large diameter pipes.
It is mainly applied to buried pipes such as water pipes, and ring joints have a gap and bending angle at the end of a unique pipe according to the standard It absorbs changes in pipe length due to expansion, expansion, and vibration to relieve pipe fatigue.
It is designed to be suitable for seismic design in pipe pipes over 350A.
