Installation

  • DE margin for assembly pipe: see table Dimensions DE ± (margin for not ovalized pipe). Check than the pipe, to input in the Quick, 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
  • Flanges: dimensions in conformity with ISO 7005-2, ISO 2531, EN 1092-2.

Assembly and start up

Description

The flange adaptor type PV allows the connection between a flange and a spigot

An adjustment of the pipe length is possible in the adjustment area (±e).

During the fitment of the pipe (measurement X) in central position the flange adaptor enables an angle of 4°.

Transport

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

Storing

The flange adaptors 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 flanges to be connected are clean and not damaged. The pipe to be connected must be perfectly round.

Assembly

  • Implementation of the connection (screws and flat tightening seals to be supplied on site).
  • Unscrew the nuts (2) and remove the counterflange (3) and the tightening seal (4).
  • Write the measurement X on the spigot of the pipe.
  • Slide the counterflange (3) and the tightening seal (4) on the spigot of the pipe.
  • Slide the pipe right into the flange adaptor. If possible it would be necessary to make the assembly in average position.
  • Slide he tightening seal (4) and the counterflange (3) against the body (1).
  • Connect the body (1) and the counterflange (3) with the nuts (2) tightening them in cross.
  • The flange adaptor is then ready for operation.
