XTRME FIX is the modern metal-to-metal press connection for industrial applica-tionsXTRME FIX, the modern metal-to-metal connection technology, is a real alternative to welding which is often dangerous and elaborate. No special training is required for the installer. No qualifi cation for welding is required. The training is carried out by KE KELIT staff .

XTRME FIX is the problem solver when quick connections or repairs are required in existing or new systems, in areas where little space is available, during bad weather, or when the medium remains in the system. A perfect connection can be made in a few seconds.

A force of up to 50 tonnes is exerted to permanently press the metal-to-metal connection without any gaskets.XTRME FIX press tools guarantee that every press connection is of the same quality

Advantages

Safe and clean connection compared to welding

Press connection comple-ted in a few seconds

Metal-to-metal connection

Withstands high pressure and temperature

Work possible in any weather

Connection can be made without complete draining of the medium from the system

No special training required

Permanent connection, pressed with a force of 50 tonnes

Temperature range: -55°C to 400°C

Measure the pipe size and the wall thickness and check whether they are within the tolerances.

Cut the pipe at a right angle. If the pipes have been pre-insula-ted remove the insulation.

Chamfer the inside and outside of the pipe. Use a sanding belt to remove loose fl akes of rust, scratches and dirt. Do not use an angle grinder.

Use the marking gauge to mark the pipe at the appropriate pla-ces. If necessary, mark the end of the un-pressed fi tting so that a visual check of the joint can be made after pressing.

Insert the pipe into the full depth of the fi tting.

Place the press tool on the fi tting. Check that the pull ring in the tool fi ts to the nut of the fi tting. Close the tool until it is locked into position.

The pressing procedure is started by pressing the button on the hydraulic unit. It stops automatically.

A perfect connection is achieved in a few seconds. A visual check of the connection is suffi cient. The press ring should be aligned with the shoulder of the fi tting and the marking should be visible.
