Tools required for installation
You need a PPR fusion welding machine. Also need a pipe cutter and deburring tool. A chamfering tool is essential for the aluminum layer. PPR-AL Stabi pipe requires standard PPR welding equipment.
Cutting the pipe correctly
Use a pipe cutter for a square, clean cut. Remove all burrs from the cut end. The cut must be perfectly perpendicular. PPR-AL Stabi pipe needs precise cutting for proper welds.
Stripping the aluminum layer
The aluminum layer must be removed before welding. Use a stripping tool made for Stabi pipes. Remove 2-3mm of the aluminum from the end. PPR-AL Stabi pipe cannot be welded with aluminum exposed.
Chamfering the pipe end
Chamfer the inner and outer edges of the pipe. This creates a smooth entry into the fitting. It prevents damage to the O-ring or seal. PPR-AL Stabi pipe preparation includes chamfering.
Cleaning the welding area
Clean the pipe end and fitting socket thoroughly. Remove all dust, oil, and moisture. The surfaces must be clean for proper fusion. PPR-AL Stabi pipe requires clean welding surfaces.
Heating the pipe and fitting
Set the welding tool to 260°C (500°F). Heat the pipe and fitting simultaneously. The heating time depends on pipe diameter. PPR-AL Stabi pipe follows standard heating times.
Heating time by diameter
20mm: 5 seconds heating. 25mm: 7 seconds. 32mm: 8 seconds. PPR-AL Stabi pipe needs precise heating times.
Joining the pipe and fitting
After heating, remove both pieces from the tool. Insert the pipe straight into the fitting. Push firmly without rotating. PPR-AL Stabi pipe must be aligned during joining.
Holding time after joining
Hold the joint stationary for the cooling time. 20mm: 5 seconds. 25mm: 7 seconds. 32mm: 8 seconds. PPR-AL Stabi pipe joints need proper cooling.
Example: installing a straight coupling
Measure and cut the Stabi pipe squarely. Strip 2-3mm of aluminum from the end. Heat the pipe and coupling. PPR-AL Stabi pipe joins with a fusion weld. Example: a permanent, leak-free connection.
Example: making a 90-degree elbow
Plan the pipe route carefully. Cut and prepare both pipe ends. Heat both ends and the elbow fitting. PPR-AL Stabi pipe turns corners with standard elbows. Example: a neat, professional installation.
Final installation summary
PPR-AL Stabi pipes install with standard PPR fusion tools. Cut the pipe squarely and deburr. Strip 2-3mm of aluminum from the welding end. Chamfer the pipe edges for smooth entry. Heat at 260°C for the proper time. Join straight without rotation. Hold during cooling for a permanent bond. PPR-AL Stabi pipe installation is straightforward with the right tools and technique. Example: a reliable installation every time.
