High pressure resistance and draw-in prevention are achieved through uniform ring processing without welding!

The rolling ring processing is a method of expanding a pipe into a ring shape. By performing rolling processing without welding the ring and the pipe, uniform ring processing becomes possible. It is compatible with the piping of connecting water supply pipes made of stainless steel pipes. We produce in our factory and provide high-quality, uniform products. Please feel free to contact us when you need our services. 【Features】 ■ Uniform ring processing ■ Compatible with the piping of connecting water supply pipes made of stainless steel pipes ■ High pressure resistance ■ High resistance to pull-out ■ Stable quality due to processing in our own factory ■ Excellent corrosion resistance and environmentally friendly stainless steel *For more details, please refer to the PDF document or feel free to contact us.
