Raccords symetriques Guillemin

Symetrical couplings Guillemin

The Guillemin-coupling is a symetrical system and apt for a large variety of applications.
Its success is mostly because of the form, which enables perfect and easy closure.

Half-coupling ringed shank, half-coupling with male or female threaded, half-coupling reduced grooved shank, half-coupling stainless steel buttweld, reduction coupling with locking rings, caps and gaskets.

Application areas for symetrical couplings Guillemin

Guillemin couplings are widely used for the transport of liquid or viscous hydrocarbons, bitumen included, chemicals or powders, except for liquefied gases and steam.

Pressures

Maximum service pressure : 16 bar.
Pressure's test : 24 bar.
Minimum breaking pressure : 48 bar.

Temperatures

The operating temperature range of fittings with nitrile butadiene rubber (NBR) seals is -20 ° C to + 65 ° C.
