Collaring

By making a collared T-junction, the need for a T-pipe is removed, thus reducing the number of soldered (copper) or welded (stainless steel) joints.

Collaring

Collaring for soldering, insert pipe notched
A radius is cut out of the connecting pipe (notching) to avoid disturbing the flow in the junction. This method is suitable for both heating and tap water systems.

Collaring

Collaring for fillet welding

The connecting pipe is inserted in the collared pipe but without notching. This method is suitable for installations in heating systems with no special hygiene requirements.

Collaring

Collaring for butt welding

The connecting pipe is not inserted in the collared pipe but welded along the joint after it has been filed down. This method is suitable for installations in tap water systems, as these demand a high level of hygiene.
