Product Description

The Arfanti grooved piping system is one of the most advanced, versatile, economical and reliable systems available today. After the pipe ends are grooved a gasket is stretched over the pipe ends. The coupling segments are then placed over the gasket and the bolts and nuts are fastened resulting In a secure and leak free joint.

A coupling can be installed 3-4 times faster than a comparable welded or brazed joint and there is no need fora flame or welding torch on the job site. A coupling can be installed by fastening a pair of bolts and nuts while using only a wrench or spanner, whereas a comparable flanged joint requires the fastening of many bolts and nuts with a pair of wrenches.
The grooved system allows for easy material take-offs and unlike a threaded system, there is no need to allow for added pipe length for thread engagement. With the removal of just a few bolts one can easily access the system for cleaning, maintenance, changes and or system expansion.

Coupling Housing 
Ductile Iron: Standard coupling housings and fittings are made of ductile Iron conforming to ASTM A536 Gr.65-45-12. The properties of Grade 65-45-12 ductile iron are as follows;65,000 psi (448 MPa) tensile strength, 45,000 psi (310 MPa) yield strength and 12% elongation.

BULTS AND NUTS
Domestic famous materials, Oval Neck bolts and heavy hoxagon nuts at ASTM A183/ISO 898,GRADE 8.8,HOT GALVANIZED.
JUNT products utilize oval neck track bolts and heavy duty hex nuts,available either in UNC threaded or ISO metric threaded*. The oval neck track bolts mate into the oval holes in the housing segments to allow for easy tightening using only a single wrench/spannerMain Parts


Rubber Gaskets
EPDM,SILICON RUBBER,PRE-LUBRICANT
During assembly the gasket is first stretched over the pipe ends which forms the initial seal. As the housing segments are installed and secured the pressure responsive gasket is slightly compressed to form a leak-tight joint. The strength of the seal is further enhanced by internal line pressure that creates downward pressure on the lips of the gasket.
