Description
Overview:
Universal boltless coupling, elbows, tees and line caps.
The Dresser Universal POSI-HOLD pipe joining system is a unique concept for providing seal and restraining pipe connections for any combination of steel and P.E. pipe. This boltless coupling features an advanced pipe joining design with fully independent seal and restraining capabilities that eliminate the need for expensive welding or heat fusion equipment. Plus, there is no need for specially trained field personnel.
The boltless design eliminates the mechanical assembly of external fasteners that provide the backbone in both sealing and restraint of bolted products. Costly trench excavation is minimized by negating the need for large bell-holes required to uniformly tighten bolted products in the ditch. Using a portable hydraulic pump, the joint assembly is made from above the ditch in the matter of only a few short minutes, thus substantial savings in labour, construction, excavation and joint assembly time are realized.
