IP-PLUS welding ring
The consumable that stays in the joint. Selected by pipe system material and nominal diameter. Delivered in airtight packaging.
Welding system
The IP-PLUS system and installation
The welding ring and the welding unit form a complete package for welding socket joints on site, without special components.
System parts
Two parts, nothing more
Welding unit
A fully automatic welding transformer that feeds the ring with the defined welding voltage and supervises the welding time. One unit serves the whole ring range.
Multi-Voltage
The unit adjusts the voltage, not the installer
IP-PLUS rings are welded with the Multi-Voltage method: the welding unit defines the welding voltage and varies it during the weld. This keeps the processing window as wide as possible even as conditions, pipe size and ambient temperature vary.
The practical benefit on site is simple: the installer never selects parameters by hand or estimates the welding time. The unit runs the cycle and signals when it is complete.
Some unit models also weld conventional electrofusion couplings with the traditional heating-coil method, so one unit covers the whole site.
What to expect from the unit
- Automatic control of welding parameters
- Supervision and confirmation of the welding cycle
- Coverage of the full ring size range in use
- Option to weld conventional electrofusion couplings
- Site-ready enclosure and supply voltage

Installation
The work steps in order
The sequence below is generic. Always follow the installation instructions delivered with the product and the welding unit's manual.
-
Cutting and chamfering
The pipe is cut square and the end chamfered. The chamfer helps the pipe slide into the socket past the ring.
-
Cleaning
The pipe end and the socket's inner surface are cleaned of dirt, sand and moisture. Cleanliness decides the quality of the joint.
-
Fitting the ring
The package is opened only at this stage. The ring is pressed into the sealing chamber in place of the rubber seal, terminals facing outwards.
-
Assembling the joint
The pipe spigot is pushed into the socket up to the insertion mark. The pipe must be in straight alignment with the socket.
-
Welding
The welding unit's cables are connected to the ring's terminals and the cycle is started. The unit controls voltage and time automatically.
-
Cooling and inspection
The joint cools unloaded for the specified time. It is then inspected visually and the line can be backfilled.
Three things that decide
- Cleanliness. Dirt and moisture on the joint surfaces are the most common cause of a failed weld.
- Insertion depth. The pipe is always pushed exactly to the insertion mark.
- Cooling time. The joint must not be loaded or moved before it has cooled.
Documentation
Welding cycles are worth recording in the project's quality documentation: joint ID, ring size, date, installer and the unit's confirmation. This keeps every joint traceable for the lifetime of the line.
