Conpipe International B.V. products

Internal cement-lining of pipesystems protects the inner steel surface from corrosion and provides excellent hydraulic properties. High purity of the cement, sand and potable water are the perfect elements for a protective lining in drinkingwater systems. High sulphate resistant cement types in combination with high density and low permeability of the cement-lining make Conpipe’s cement-lining extremely suitable for conveying (sea)water that contains aggressive elements. Cementlined pipesystems, mainly used in drinkingwater, coolingwater and firewater applications, are relatively cheap and have a very long lifetime.

In-Situ lining can be done anywhere in the world. Equipment and crew are sent to the site for lining of sections of pre-installed underground or above ground pipework. The lining will meet the same requirements as lining applied in the shop. Pipes over 24” and up 120” in diameter are lined by the so-called man-entry method. The machine operator travels along the pipe with the lining machine. The cementmortar is sprayed against the pipewall and smoothened by a rotating trowel blades or static dragtrowel.

Conpipe International has facilities for the application of coating systems for the interior and exterior of steel pipelines. The products used are generally high technology paints based on epoxy or polyurethane polymers, or other lining materials such as glassflake with resins such as polyester, vinylester or Fusion bonded epoxy powder linings. Depending on the service requirements. Typical applications include heavy-duty service conditions. Excellent resistance to immersion in salt-water, extreme temperature area’s and wear and tear.

Conpipe International’s high quality rubber lining pipework with several types of high quality rubber is the optimal protection for metal under severe conditions. In- and external blast cleaning, internal rubber lining, vulcanising and external paintcoating are standard manufacturing activities that are carried out in-house.

Highly corrosive medium carrying pipework require high quality linings to protect the steel. Conpipe International offers expertise in manufacturing and lining of steel pipework, ranging from nps 1/4” to 24”, to international standards providing a long service life. Plastic linings in PTFE / PFA / PP / PVDF can be applied.

Corrosion and erosion drastically reduce the life-time of the steel pipework and equipment in many industrial applications. Durable linings are required to protect the steel from chemical attack and wear. Underground pipelines need protection against corrosion. Conpipe has production facilities for external polyethylene coating of pipes and fittings. The steel surface is cleaned by blast cleaning to SIS 055900 grade SA2.1/2.
