R.J Pipe Restrained Joint
HANYCO provides various types of earthquake resistant ductile iron pipes to increase the safety of water distribution and transmission pipe lines. By using this kind of pipes, our customers capable to protect the applied investments as well as preventing from causality and financial loss.
One basic advantage of Ductile Iron Pipe systems vs. alternative materials is the vast amount and variety of thrust restraint joint options. These restrained joints are used to resist thrust forces as an alternative to thrust blocking. A restrained joint is a special type of push-in or mechanical joint that is designed to provide longitudinal restraint. Restrained joint systems function in a manner similar to thrust blocks, insofar as the reaction of the entire restrained unit of piping with soil balances the thrust force. These special joints offer flexibility and are simply and quickly installed. Push-in restrained joints are available in two basic types of designs: those with restrained push-in gaskets and specially designed push-in restrained joints.
