THERMAL INSULATION OF RIGID EXPANDED POLYURETHANE PIPES FOR TEMPERATURE MAINTENANCE
With the aim of reducing heat loss in pipes made of steel, GRE, or any other material, pipes are coated with a polyurethane foam.
This thermal coating prevents PARAFFIN precipitation and the buildup of HYDRATES.
In the case of heavy crude oils, this coating allows the temperature to be maintained in pipelines without the need for external heat. This coating keeps viscosity of the crude oil low and reduces the chances of clogging, which results in lower operative costs.
Technical and cost-effectiveness arguments that support the use of thermal coating. Technical article written by PSS staff and published by the IAPG (Instituto Argentino del Petróleo y Gas) Newsletter Petrotécnica in February 2019.DOWLOAND REPORT
PSS uses a quality assurance system in accordance with ISO 9001 version 2015. This quality assurance system meets strict international rules, such as the European guidelines EN 253, among others.
POLYURETHANE as an insulation material on pipelines is applied in a CONTINUOUS process with cutting-edge equipment. This production method offers several advantages: higher quality, homogeneity, efficiency, and control during production.
The thermal insulation is protected by a HIGH-DENSITY POLYETHYLENE external layer, which is "applied" directly onto the insulation material (polyurethane). This ensures a high adherence of the coating layers, which provides mechanical resistance and guarantees a correct insulation during the life cycle of the project.
Application of thermal insulation in accordance with EN-253 rules.

Above the ground or underground pipelines
Optionally, and for more severe conditions of use, electric heat tracing ducts can be installed.
