ABOUT BULGE SYSTEM:

 

Connection theory:

You can see the Bulge connection theory chart( attached picture ) or the installation example in page 03 and page 09 of our Bulge system catologue.  It shows the connection and sealing principle by screwing down the fitting and nut so as to press the O-ring( EPDM) to seal by the bluging ( which we use our bulge tool to expand one joint on the pipe).

Advantages of Bulge fittings：

 Advanced loose joint technology, not only possesses the performance of convenient installation and maintenance, but also provides measures to prevent any possible leakage.

■Double thick O-ring gasket, double safety assurance

■Qualified EPDM gasket, standing 110℃ high temperature, long life-service

■Strong connection strength, the highest tensile strength except welding connection way

■Thread and flange connection, suitable for domestic habit, high installation quality

■Fast installation, no need of threading to the pipes, saving 60% time of welding way

■Smart installation tool is convenient to use in pipeline well, hung ceiling and other narrow room

■Loose joint is easy to unload, change and maintain
