PURPOSE:

Pre-insulated pipes and fittings manufactured by JIZZAX POLIMER PLAST LLC
are pipe-in-pipe type structures consisting of a steel pipe that transports water, steam, oil, gas or other products.

APPLICATION:

Upon agreement with the design organization, it is permitted to use insulated pipes in a polyethylene casing in impassable channels.
It is also permitted to use insulated pipes for pipelines transporting other substances (oil, gas, etc.).
At the customer’s request, any insulated fittings (bends, compensators, tees, PE casing, etc.) are manufactured.

All products are equipped with wires of the ODK system (to prevent the possibility of an accident on the heating main, pre-insulated pipes in a polyethylene casing are laid at a depth of 50-70 cm.

This standard applies to steel and shaped products with thermal insulation made of polyurethane foam in a polyethylene casing or with a steel protective coating (hereinafter referred to as insulated pipes and products) intended for underground laying of heating networks (in a polyethylene casing – using a trenchless method, with a steel protective casing – in through channels and tunnels) and aboveground laying of heating networks (for pipes with a steel protective coating) with the following design parameters of the coolant: working pressure of no more than 1.6 MPa and a temperature of no more than 140 ° C (an increase in temperature of no more than 150 ° C is allowed within the schedule of high-quality regulation of heat release 150 ° C – 70 ° C).

ADVANTAGES

Service life of thermal insulation pipes and fittings for over 30 years
The tightness of the polyethylene shell eliminates corrosion from groundwater and electrocorrosion (stray currents)
Reduction of losses in heating networks by more than 2 times compared to traditional types of insulation
Reduction in the cost of laying the pipeline (simpler and cheaper than expensive reinforced concrete structures)
