Tubing, casing and line pipes of steel with internal corrosion-resistant coating

Purpose of coating

Protects the inner surface of tubing string, casing pipes and couplings as well as line pipes against corrosion.

Field of application

Coated tubing string is designed to be used in injection and development wells operating in flowing mode or equipped with electric centrifugal pumps, as well as in wells of injection system.

Coated casing pipes are intended for fixing oil and gas wells with extended service life. Coated line pipes are used for construction, reconstruction and repair of production and technological oil, gas and water pipelines.

Types of internal coating depending on operating conditions

• standard 80;
• thermo 120;
• thermo 150 and more.
• (Maximum operating temperature is 80, 120, 150 °С).

Range of pipes with coating

• Tubing string - from 60 to 114 mm;
• Casing pipes - from 114 to 340 mm;
• Line pipes - from 60 to 530 mm;

Coating design

• one-layer based on high-viscosity materials;
• two-layer based on powder materials.

Coating properties

• resistant to oil, fuels, industrial water and sewage;
• resistant to the damaging effects of stray currents;
• high degree of adhesion of the coating to the steel surface;
• high mechanical strength.
