Underground
Insapipe

Insapipe is a factory fabricated and insulated underground piping system designed for direct burial into an unlined trench. The product is manufactured generally to British Standard 4508 for "Thermally Insulated Underground Piping Systems" and EN253. The system consists of any type of process pipe conveying hot or cold fluids, centralised within a high density polyethylene outer casing. Insapipe is fully dedicated to, compliant with, and has been assessed as being an AS/NZS 9001 Certified.

Pre-insulated lengths

Pre-insulated Lengths

The annular space between pipe and casing is machine filled with polyurethane foam which expands and, upon setting, forms a totally uniform insulation around the pipe. As an option, for chilled water and other non cyclic applications, kitsets for bends and tees are available for fabrication on-site, should these prove more suitable for particular sites with unknown route parameters

Pre-insulated fittings & jointing

Expansion Bends (90deg)

Expansion Bends (90 degree)

An expansion bend is used where the pipe direction must change at 90° or allowance for thermal expansion is required. Designed to take up to 20mm of thermal expansion

Straight Tees

Straight Tees

A straight tee is used where a branch from the mainway pipe is required. Branch diameter is always smaller or equal to the mainway diameter.

Cross over tees

Cross over tee

A cross over tee is used where a branch from the mainway is required to clear a pipe adjacent to the mainway pipe. Branch diameter is always smaller or equal to the mainway diameter.

Mini-bends

Mini-bends

A mini-bend is used where the pipe direction must change at 15°, 45° or 90° (or custom angle to suit your requirements). Mini-bends must not be used to cater for thermal movement.

Anchors

Anchors

An anchor is used to prevent any movement at a particular point in the pipe run, thereby forcing thermal movement away from the anchor which can then be taken up by expansion bends or offsets.

Straight joint kit U/G

Straight joint kit U/G

The straight joint kit comprises a metal sleeve, rivets, jugs, mixers & polyurethane foam A & B to insulate the joint, heat shrink sleeve & patch to completely seal the outer casing to provide an effective waterproof seal.
