LINK GS PFA25 for ductile iron pipes

• DE margin for assembly pipe: see table Dimensions DE ± (margin for not ovalized pipe). Check than the pipe, to input in the Link, is not ovalized more than 3mm and that the DE dimension with ovalization is not out of the margin. If not it is necessary to proceed re-rounding pipe (see catalogue WATER MAINS for DUCTILE IRON PIPES and FITTINGS)

• Possible adjustment: dimension X ±e (50mm DN 300-2000)

• Angular deflection in degree + or – 2 degrees

 Warning: this coupling will only be installed in a valve chamber. Do not install it in buried version

Description

The coupling type PS allows the assembly of two spigots

Transport

The transport of the pieces must be done professionally in order to avoid damages on the material.

Storing

The coupling must be protected from bad weather and pollution. During a long storage period a protection against UV is necessary.

Assembling in the pipe network

It is necessary to control that the pieces (pipes) to be connected are clean and not damaged.

Assembly

• To remove the two tightening rings and the tightening seals.
• It is necessary to write the measurement X on the spigot.
• The tightening flanges (1) and the tightening seals (5) slip on the pipes spigots.
• To position the coupling type PS (2) in the space between the two spigots by respecting distance X on the two sides.
• The assembly joint-pipe-joint will be perfectly centered compared to the two spigots to be connected.
• To bring closer the two tightening flanges (1) as well as the two tightening seals (5) towards the pipe of the coupling (2) by centering them.
• To tighten in cross of the tie rods so that centering is optimal to obtain homogeneous tightening.
• Tightening must be progressive to obtain the required tightening torque.
• The coupling is then ready for operation.
