Corrosion-Resistant Pipe Coating

OMK manufactures pre-coated medium and large-diameter pipe with factory-installed thermal insulation for above-ground and underground trunkline, process oil and gas pipelines, and public utility and residential heating networks, and process lines as well as municipal heating networks.

Pre-insulated pipe is a package made up of steel pipe, an ID and OD corrosion coating, a layer of PU foam insulation, and an outside protective shell. Optionally, the pipe can be equipped with heat tracers (skin systems) and fire inserts.

Thermal insulation coating increases the pipeline reliability, protects the medium being transferred from low temperatures, reduces heat loss, and prevents the thawing of soils.

The design is two steel pipes of different diameters using the pipe-in-pipe technology
with the annular space filled with an insulating material (polyurethane foam).

The OD joints are covered with thermal insulation material and a protective cover.

Application:

• Prevention of ground thawing
• Stabilization of wellhead position
• prevention of well branch collapse and complications associated with ground cave-ins around wells, including well bore sinkholes during the thawing of subsiding and caving soils as well as permafrost.
