The OFRA couplings free joint made of glass-fiber reinforced polyester, chemically bonded to an EPDM rubber gasket on the entire width of the coupling.
The OFRA coupling is suitable for all degrees of working pressures. It withstands a maximum pressure of 32 atmospheres and also total vacuum.
GRP pipes can be connected with Fibertech manufactured GRP connectors, bandaging connectors, segmental connectors for connecting fittings, mechanical connectors, manhole connectors.
The connector enables angular deviation connections. The allowed angular deviation:
Pipe Diameter Deviation in Degrees Celsius
· Between 300 and 600 mm - 2.0 degrees Celsius
· Between 650 and 1000 mm - 1.5 degrees Celsius
· Between 1100 and 1500 mm - 1.0 degrees Celsius
· Between 1600 mm and upwards - 0.5 degrees Celsius
The connectors are manufactured and tested pursuant to US Standards - ASTM D4161.
