Installation Manual - Future Pipe Industries

The temperature of the heating blanket should be at least 90°C for applications of medium below 65°C and
125°C for medium temperatures between 65°C and 90°C for the Easy fit adhesive.
For detailed instructions we refer to the Wavistrong Easy fit Adhesive Instructions, enclosed in the Wavistrong
Adhesive set.
Curing time for Easy fit adhesive is one hour (see fig. 4.3.a. page 12) and one hour warming up time.
Curing time starts after the surface of the pipe has reached the required temperature underneath the heating blanket.
During curing the joint should be insulated for example by using an insulation blanket and seal off the pipe ends to
prevent draughts through the pipe.
Because of their configuration, flanged joints and laterals are difficult to cure from the outside by using a heating
blanket. They can be cured with the following alternative procedure:
A Roll up the heating blanket and place it on the inside of the pipe at the machined end. Fill the space inside
the blanket with heat resistant material to ensure that the blanket is pressed against the pipe wall.
The electrical cables must not be inside.
B Heat the joint on the inside with a hot air gun / paint stripper or infra red device. Control the temperature with
a digital temperature gauge. For laterals, the branch and the nearest joint must be cured first. The remaining parts
can be cured with a heating blanket.
Do not move the joint during setting of the adhesive! This can result in failure of the joint.
After the cured joint has cooled down it may be loaded.
Note In many cases the number of site joints can be reduced by prefabrication (spoolbuilding) in the factory.
