ASSEMBLY AND DISASSEMBLY

Self-Restrained Dismantling Joint Type JPL DN80-1200

Product family
Couplings and assembling
  • The self restrained dismantling joint JPL, (reduced number of tie bars compared to the standard version JP) allows installation in insertion or removal of an equipment between two fixed flanges of a pipeline.
  • The sliding system can reach a +/- 20mm to +/- 40mm 50 mm displacement according to the DN.
  • For this type of self restrained dismantling joint the locking of the valve to the pipeline is made by the tie bars and the gland.
  • This piece is designed and manufactured in alimentary quality for potable water and irrigation.
  • They have a mobile MALE PART and one fix FEMALE PART. Between these two parts there is an intermediate flange allowing a good closing and making a good seal in contact with seal joint.

Range
The self restrained dismantling joint JPL exist in a range from DN80 to 1200 PN10 and PN16, for pressure PFA10 - PFA16

Before assembly

Check the final assembly length of the self restrained dismantling joint.

The tightening will be carried out with a torque wrench.

Assembly

  • Position the self restrained dismantling joint in its location, ensuring that the position of the holes in the flange coincides with the position of the holes of the elements to be connected.
  • Place the gaskets in the flat faces of the flanges to be connected.
  • Tighten the nuts and lock nuts of the main tie bars in the order indicated in the table below. The tightening torques to be applied are shown in the table below.
  • Tighten the nuts of the intermediate tie rods (sealing) in the order indicated in the diagram below. The tightening torques to be applied are shown in the tables below.
