The penetration of the pin on the plug is approximately 150mm allowing efficiency without impairing the break up 15 in its longitudinal axis, thus accepting small landforms without causing additional stress to the pipe and mainly double security sealing pressure due to double welding. In this type of joint, once housed the pin inside the plug, spatula will be placed in the annular space between pipe and pipe-based mastic one bite and accelerated fiberglass resin, a polymerized first time the inner weld or seal welding is now completed.

The second outer weld or solder glass felts made with resin and accelerated width proportional to pipe diameter and thickness corresponding to withstand the working pressure required, never less than the wall thickness of the pipe. Thousands of feet of pipe installed in private industry and public works bond with this system supports the concept that this system is more efficient.
