Style WRI-LC gaskets provide a seal at relatively lower seating stress. This means that our design requires less bolt load to seat, yet still has the recovery like a standard spiral wound. The SWRI-LC gasket is typical to 150# and 300# class flanges, where users have a concern with insufficient potential of pre-load. But, the density of the SWRI-LC gasket can be varied to meet virtually any requirement. Electronic controls on DELTAONE' SpiraSeal machines assure high quality precision welding with equal spacing, the correct number of metal plies on the gasket inside periphery, proper ratio of metal to filler, proper number of metal plies on the outside and spot welds on the O.D.
