External corrosion-resistant coating based on extruded polyethylene

Three Layer External Polyethylene Coatings (3РЕ)

This 3 layer corrosion protection high performance coating consists of liquid epoxy layer, polymeric adhesive and high density polyethylene (HDPE).

3 layer PE coating is designed to protect buried underground and subwater oil, gas and water pipelines in environments where superior mechanical protection and high operating performance characteristics are required.

Also it can be used for directional drilling and for road and river crossings becouse of excellent abrasion and impact resistance.

The unique application process of UKRTRUBOIZOL provides almost monolithic coating structure that can not be dislayered and prevents delamination and loss of adhesion. During construction, the coating demonstrates excellent field handling and flexibility characteristics, thus minimizing construction installation costs.

The epoxy layer provides excellent long term corrosion resistance and resistance to cathodic disbondment which reduces the cost of cathodic protection during the operation of the pipeline. The adhesive layer provides superior adhesion between epoxy and PE layers. The polyethylene layer protects the pipeline during transportation, thereby, reducing costly repairs while also providing added in-ground protection against shear forces, chemicals and abrasive soil conditions.

Сonsists of:

The epoxy layer provides excellent long term corrosion resistance and resistance to cathodic disbondment which reduces the cost of cathodic protection during the operation of the pipeline.

The adhesive layer provides superior adhesion between epoxy and PE layers.

The polyethylene layer protects the pipeline during transportation, thereby, reducing costly repairs while also providing added in-ground protection against shear forces, chemicals and abrasive soil conditions.

Properties and Benefits (3РЕ):

Two Layer External Polyethylene Coatings (2PE)​

This 2 layer corrosion protection system combines the proven protective qualities of a polyethylene (PE) outer coating with a special polymeric adhesive.
2 layer PE coating is designed to protect buried underground oil, gas and water pipelines in environments where superior mechanical protection and high operating performance characteristics are required.

2-layer insulation consists of similar components as 3-layer insulation, but it does not have the first layer of insulation, namely: epoxy primer.

Сonsists of:

The adhesive layer provides superior adhesion between epoxy and PE layers.

The polyethylene layer protects the pipeline during transportation, thereby, reducing costly repairs while also providing added in-ground protection against shear forces, chemicals and abrasive soil conditions.

Properties and Benefits (2РЕ):

Three Layer External Polypropylene Coatings (3PP)

This 3 layer corrosion protection high performance polypropylene (PP) coating consists of liquid epoxy layer, polymeric adhesive layer and polypropylene layer.

3 layer PP coating is designed to provide the most effective protection for buried and subwater oil, gas and water pipelines with high operating temperature in environments where superior mechanical protection and high operating performance characteristics are required.
Also it can be used for directional drilling and for road and river crossings becouse of excellent abrasion and impact resistance.

Technical characteristics:

Pipe diameter: 32-1422 mm.

Note:

Technical characteristics of a covering are regulated by requirements of ТУ of the producer or requirements of the customer

Purpose and scope:

PURPOSE OF THE COATING – effective corrosion protection of pipelines and the increased level of protection against mechanical damages, in the conditions of high temperature of operation of the pipeline and environment.

FIELD OF APPLICATION – underground laying of gas pipelines, oil pipelines, product pipelines, etc. pipelines (including – main), sea pipelines, casings (cases) including – large diameter for the arrangement of transitions under railways and highways, technological pipelines of the increased temperature mode of operation.

The unique application process of UKRTRUBOIZOL provides almost monolithic coating structure that can not be dislayed and prevents delamination and loss of adhesion. During construction, the coating demonstrates excellent field handling and flexibility characteristics, thus minimizing construction installation costs.
The epoxy layer provides excellent long term corrosion resistance and resistance to cathodic disbondment which reduces the cost of cathodic protection during the operation of the pipeline.
The adhesive layer provides superior adhesion between epoxy and PP layers.
The polypropylene layer provides the most durable pipe coating available and protects the pipes during transportation, handling and installation, thereby, reducing costly repairs while also providing added in-ground protection against shear forces, chemicals and abrasive soil conditions.
