Specifications

Our company is a specialized manufacturer, supplier and distributor of flanges of national and international standards.

 

Threaded Flanges can be fitted to the pipe without welding, though a seal weld can sometimes be used. They are suitable for small diameter high pressure services. At larger diameters, the difficulty in machining the thread on to both the flange and pipe makes them unviable. They are also not suitable for areas having high external loads, particularly torsion.
