Pre-insulated pipes introduction


A pre-insulated pipe consists of three parts

The carrier pipe, made of made steel, stainless steel, plastic or copper.

The insulation, made of polyurethane foam (PUR foam) or polyisocyanurate foam (PIR foam), which is specially suited due to its high insulation qualities compared to mass and volume.

On the outside a protective casing of plastic or steel.

The choice of carrier pipe, foam type and foam thickness, as well as the material for the casing, is designed for a specific project together with the customer.

Casing:


As standard, industrial pipes are supplied with a PE-HD (polyethylene) casing, in black.

These casings have many advantages, as they are impact-proof, watertight, resistant to salt and chemicals, hygienic and non-corrosive. Pipes with black PE-HD casings are UV-resistant, as a result of the addition of UV-retardant

additives. Black casing pipes can therefore be used both outdoors

and indoors.

Pipes with black PE-HD casings are always used for buried pipe systems.
