LONG EXTRA joints are used for repairs of pipe failures in case that pipe rupture occurs, or as substitution for existing joint if there is a leakage on connection.
Basic advantages of using LONG EXTRA joints are:
- the defect is repaired without cutting the pipe (for minor leaks and without turning off the water);
- with one coupling, a defect can be eliminated on any pipe of the same nominal diameter, regardless of the material of the pipe;
- the permissible angular deviation of the connecting pipes is up to 5°;
- they are used for larger damages (300-500 mm) depending on the nominal diameter of the pipe;
- to eliminate one defect, one coupling is sufficient (and not two as in the case when the pipe is cut);
- if there was damage to the sealing surface of the pipe in the place where there was a "Žibo" ("Gibault"), "Vitlak", "Dalma" (or some other) coupling by simple assembly LONG EXTRA of the coupling, the defect is eliminated, without cutting that part of the pipe, because the distance between the coupling seals is LONG EXTRA larger than with the above couplings.
As an improved and particularly innovative solution, after almost a quarter of a century since the initial presentation of these couplings, we have created a new way of sealing the couplings LONG EXTRA (and all further derived products based on these couplings), which you can see more about in the section EXTRA LINK GASKET.
