COMPLETE PIPE SYSTEM 01 — 04Fittings &
Fittings &
Jointing Systems
Pipe, fitting and connection are selected as one engineering system. The jointing method depends on pipe construction, diameter, pressure or sealing duty, access, equipment and the approved field procedure.
Connection interfaceFabricated PE fittingProject-specific configuration
SF / 01Match the connection to structural demand, sealing duty, field access and equipment.
Use the applicable installation, inspection and acceptance procedure for the confirmed configuration.
02 / JOINTING METHODSDifferent products use
Different products use
different connections.
These photos and diagrams show the connection routes, not a universal joint specification. Confirm compatibility and the approved installation procedure for the selected pipe.
01 THERMAL FUSION
Butt Fusion
Review material, wall configuration, machine range, alignment, heating and pressure-control requirements.
02 ELECTROFUSION
Electrofusion Coupling
Confirm diameter, pressure class, preparation, installation clearance and fusion parameters.
03 ELECTROFUSION
Electrofusion Band Joint
An external electrofusion band for compatible structured-wall pipe joints. Confirm the approved joint design and installation procedure.
04 MECHANICAL SEAL
Spigot-and-Socket Joint with Two Sealing Rings
Review watertightness, insertion depth, angular deflection, bedding and field installation procedure.
05 INTERFACE
Flanged Joint
For valves, equipment and transitions where pressure, bolts, backing rings and gaskets are coordinated.
06 FABRICATION
Extrusion Welding
Used for applicable fabrication and non-pressure structural work under an approved procedure.
03 / FABRICATED COMPONENTSComplete the pipe system,
Complete the pipe system,
not only the straight pipe.
Project scope may include bends, tees, reducers, branches, flanged transitions, manholes or chambers where manufacturing capability and design information are confirmed.
04 / CONNECTION REVIEWSend the pipe and
Send the pipe and
site conditions together.
Product, diameter, pressure or sealing duty, joint quantity, working space, power, equipment, drawings, inspection and destination.
