| Home > What is Permalok? | ||||||||||||||||||
| Permalok is a steel pipe
solution which employs a patented interlocking press fit connecting
system for joining pipe sections in the field. Our precision-machined
joint is quick, easily made up, permanent and leak proof. The connection
is completed directly in line and put together using the existing jacking
frame on your trenchless equipment or the force from your ramming machine.
Permalok provides a dramatic advancement to trenchless construction by eliminating the need for in-field welding. In addition, Permalok reduces equipment and crew down time and eliminates the need for repairs of coatings or linings at welding areas. Permalok utilizes silicon sealant to lubricate the grooved profile of the connection, which then performs as a gasket creating a water-tight connection. Its unique profile is machined to tolerances of less than 0.010 of an inch, which creates a joint of consistent quality and integrity that is leak resistant even under considerable pressure. The combined advantages of the Permalok system make it the ideal piping solution for Microtunneling, Pipe Ramming, Pipe Jacking, Auger Boring and Horizontal Directional Drilling.
