- Blind (BL) Flanges: Used to seal pipe ends, useful for inspection and maintenance of pipe systems.
- Socket Weld (SW) Flanges: Suitable for small pipe diameters, easy to assemble and disassemble.
- Slip-On (SO) Flanges: Easy to weld, suitable for non-critical applications.
- Lap Joint (LJ) Flanges: Flexible and convenient for systems requiring frequent disassembly.
- Orifice (FWO) Flanges: Specially designed for installing measuring equipment such as orifice plates.
- Long Welding Neck (LWN) Flanges: Designed for easy connection to pipes in high temperature and corrosive environments.
Pressure classes
Our flanges are available in various pressure classes, ranging from 150# to 2500#. Whether you have a low-pressure or an extremely high-pressure application, we have the right flanges for your project.
Flanges that conform to DIN/EN and API standards
Along with our extensive selection of products that conform to ANSI standards, we also supply flanges that comply with DIN/EN and API standards. Which means you can be assured of international quality standards for your specific project requirements.
