Installation
Range of diameters DN25-DN300
Application

The grooving process can be made in two ways:

  • through embossing – the pipe wall is pressed between rolls (material deformation),
  • through cutting – the pipe wall is cut circumferentially (removing the material).

Below is a list of steps to follow in case of installing grooved connectors. If additional steps are required for certain models, they can be found in the technical section of KAN-therm Groove Catalogue.

Check and prepare pipe ends

To achieve the optimum quality of the sealing, the outer surface of the pipe ends must be free of any dents, protrusions, rolling marks or other surface defects such as loose paint, deposits, dust, chips, grease or rust.

Check the seal

Make sure that the supplied seal is suitable for the intended application. The stripe colour determines the seal type.

Grease the seal

To make it easier to insert the pipe and install the connectors without pinching, apply a thin layer of grease available in the KAN-therm Groove offer to the lips of the seal and the outer coating of the seal. Any other suitable lubricant may be used, unless it has properties that could lead to seal damage.

Mount the seal

Mount the seal on one end of the pipe, so that the end of the pipe is visible. No part of the seal should extend beyond the end of the pipe.

Connect the second pipe

Measure and match the two ends of the pipes you want to connect. Slide the seal over the ends and centre it between the grooves of the pipes joined. No part of the seal should enter the pipe
grooves.

Mount the seal

Mount the seal on one end of the pipe, so that the end of the pipe is visible. No part of the seal should extend beyond the end of the pipe.

Twist both halves of the clamp

Mount both halves of the clamp at the same time. Ensure that the wedges of the coupling engage in the grooves

.

Insert bolts and place nuts

Insert all bolts and tighten nuts by hand.

Make sure that the oval bolt head is locked into the bolt hole in the connector housing.

Tighten the nuts

Tighten the nuts alternately and with equal force until the protrusions of the clamp touch each other (metal-to-metal contact). 

Tighten the nuts a quarter or half turn to make sure that the bolts and nuts are tight against the attachment.

The use of a torque spanner is not required.

Tighten the bolt nuts

Always tighten the nuts to the required torque with a torque spanner. 

Usually after tightening the bolts and nuts, you can see gaps between the clamp protrusions. 

The gaps between the protrusions should be the same on both sides of the connector.
