As soon as
dry natural gas was introduced into a gas company's cast iron pipes,
the irreversible process of drying out of the jute packing in the
pipe joints was started. This inevitably leads to gas leakage within
a very short time. Any movement of the pipe due to traffic or ground
movement accelerates this process by squashing the lead caulking.
The proven,
permanent solution to cast iron leaks!
Don't replace
cast iron pipes. Make them as good as new by encapsulating the
joints with PLCS.
Over the
last 30 years, millions of joints have been encapsulated.
Tests by
Cornell University (for the New York Gas Group) and British
Gas prove 50 years minimum life expectancy.
The joint
is encapsulated in a tough, flexible synthetic rubber that is
permanently adhered to the pipe, yet allows the joint to move.
A 6" bell
joint can be sealed in less than 15 minutes.
Used by
more than 60 major gas utilities in the USA.
