Overview
Product overview
A Lap Joint Flange is a versatile component used to connect pipes or fittings. This flange consists of two parts: the flange ring, typically made of carbon steel, and the stub end, crafted from a material compatible with the connected pipe or fitting. The flange ring features bolt holes around its perimeter, allowing it to be securely bolted to another flange or equipment.
Product Range
We offer these flanges in various international standards, including JIS 10K, PN16, and PN10.
Conclusion
