Thick layer fast setting Two component polyurethane coatings applied mainly for the insulation of exterior surfaces of main pipelines, fittings and armature immersed in fresh (Im-1, according to ISO 12944-2) or sea water (Im-2), and also buried in soil (Im-3).

Coatings of Welepipe series refer to materials based on polyurethane with 100% dry residue, which proven themselves as the most perfect insulation coating of known polymeric liquid anticorrosive compositions for protection of underground and underwater steel and reinforced concrete structures.

By isolating and anticorrosive properties, adhesion and impact resistance, cathodic disbonding and other indicators, coatings based on polyurethane composition Welepipe meet the requirements of standards EN 10290, State Standard 51164 and State Standard 4219, which define conditions as for polyurethane exterior coatings applied in a liquid state and for protection of pipelines against corrosion.

On-site application
Field application

Main advantages

  1. Can be applied both in the factory and in the field conditions.
  2. Can be applied with a thickness up to 3 mm in one technological cycle without slipping, streaks and other coating defects.
  3. When applying by spraying the material is quickly cured (10 minutes at T = 23°C), which allows storing pipes almost immediately after application of coating.
  4. Have high adhesion, both to steel (>18 MPa), and to concrete (>3.5 MPa – concrete destruction) surfaces and can be applied without bonding primers.
  5. Have a high impact strength (>20 J) and abrasion resistance (100-130 mg loss of weight in 1000 cycles - 1 kg of load - wheel H-17).

WG-Welepipe

is a two-pack, solvent free, high build polyurethane coating applied by preheated plural component airless spray application unit with a proportioning pump. Designed for maintenance-free protection of exterior metal and concrete surfaces of pipes and their joints, fittings, slide valves, reservoirs and tanks as well as other structures immersed in water, buried / underground or laying above-ground. Coating has temperature resistance up to 60°C and gel time to 120 seconds.

WG-Welepipe XF

is a two-pack, solvent free, high build polyurethane coating applied by preheated plural component airless spray application unit with a proportioning pump. Designed for maintenance-free protection of exterior metal and concrete surfaces of pipes and their joints, fittings, slide valves, reservoirs and tanks as well as other structures immersed in water, buried / underground or laying above-ground. Coating has temperature resistance up to 60°C and gel time to 45 seconds.

WG-Welepipe BG

Is a two-pack, solvent free, high build polyurethane coating for manual application. Designed for application over the small areas such as joints, fittings, slide valves etc., as well as repair of the main layer of Welepipe coating such as mechanical or other damages.

WG-Welepipe JW Primer

Is polyurethane one-component, ready to use primer and adhesion promoter for coating system. Recommended to use as a primer for plastic, fiberglass reinforced plastic and similar surfaces in order to promote adhesion of the following paint system.

WG-Welepipe JW
