| The best motivation to design any
new product is the need to solve a problem. Steel pipe is an ideal
solution to meet the needs of trenchless underground pipe installations.
The problem is that construction efficiency is hindered by the expense
of lost production hours and the questionable integrity and specialized
payroll associated with in-field welding of joints. The invention
of the Permalok Interlocking Pipe Joining System provides a dramatic
advancement to the quality of tubular steel construction by providing
a pre-installed precision joint connection which is quickly, easily
and permanently mated during field construction.
Permalok eliminates the need for in-field welding and the down
time associated with it. The Permalok connection is specifically
designed for the trenchless excavation industry because it is flush
with the interior and exterior surfaces of the pipe. Joint quality
is further enhanced because the Permalok connection is consistently
round, true and perpendicular to the pipe axis. Its unique stepped
profile makes stabbing and aligning easy and quick. What’s
more, the Permalok design, combined with the use of a sealant such
as RTV Silicone, will not leak even under considerable pressure. |
