Insulation For Pipes Used In The Manufacturing & Process Industries

PAROC Pro Lock simulates overlapping double layers in one application – saving time and money

There are a great number of opportunities within the industrial sector for reducing heat losses. Far too often, specifications from previous projects that are decades out of date are simply adopted without prior consideration.

Better insulation for industrial processes offers many advantages: energy and costs are saved, CO2 emissions are reduced and processes are undertaken in a more efficient way.

Steam and other hot fluids are often channelled through pipelines and installations in industrial plants. For optimal production processes, it is usually desirable that the heat generated is retained. If pipelines and installations are not insulated correctly, heat is lost and significantly more energy is required to maintain the necessary temperature level.

Insufficient maintenance of process insulation can also lead to large heat losses on a yearly basis. High amounts of heat and energy are required for most industrial processes. Within the European Union, the industrial sector accounts for over 27% of final energy consumption.

Optimisation of energy consumption within industrial plants is therefore essential. In every industrial process or plant, owners and operators strive to make investments which will guarantee optimal functionality and efficiency and generate the greatest possible profits.

When operating temperatures exceed 250°C, or required thickness exceeds 160 mm, overlapping double layer insulation is required. Paroc offers double layer solutions, but through innovation also offers its Pro Lock option, which simulates overlapping double layers in one application.
Industrial pipelines are insulated efficiently using the PAROC Pro Lock industrial pipe section.

Expansions of the pipeline at high temperatures are offset by the z-lock cut into the ends and down the length of the section, and heat losses are reduced by up to 25%. Compatible double layer segments may be used for pipe bends, which guarantee optimal insulation for the entire pipeline.

PAROC Pro Lock WR 100 – for long service at up to 350°C. For higher temperatures use PAROC Pro Lock WR 140.
