Dedicated Flange Adaptor covering a similar range to the straight coupling , are manufactured to join plain ended pipe to flanged valves,fittings,flow meters and pipes.Flange drillings are available to all international standards or to customer specifications.Dedicated couplings join pipes of the same outside diameter,such couplings can be manufactured to suit both metric and imperial dimensions for Steel,Ductile Iron pipes etc.
Design Features
◆ Long Life Sealing
- The elastometic sealing gasket can supply more than 25years lifetime.
◆ Easy to Adapt
- Available to many installation condi- tions,like underwater,kinds of ditches in any weather.
◆ Excellent Coating Protection
- The normal painting for universal
fittings is RAL5017 fusion bond
epoxy coated powder which with
good anticorrosion characteristic,
and the bolts and nuts are Dacromet coating,which with good anticorro- sion,thermostability characteristic.
