What are the construction methods of glass fiber reinforced plastic paint anticorrosive pipes?
Epoxy coal tar coating consists of two main components with epoxy coal asphalt composition, is a (epoxy) B (curing agent) two-component coating, with good adhesion, toughness, moisture resistance, water resistance, chemical resistance, has the properties of prevent various ions through the film, and is coated with objects with the expansion of shrinkage characteristics. The paint film never falls off or cracks.
Epoxy coal tar pitch is a kind of anti-corrosion form with high cost performance. The engineering test shows that the epoxy coal asphalt is used as cathodic protection.
Oil and gas pipelines used for twenty years, basically no corrosion phenomenon. As part of a group of coal tar epoxy primer and topcoat are based on epoxy resin and coal tar as the main film-forming material, add a variety of anti rust paint, insulating filler, toughening agent, leveling agent, diluent, anti settling agents and other materials, the B component is modified amine curing agent or curing agent the main material, adding fillers. When the product is sold, the A and B parts are supplied together, and the mixture is mixed in proportion during construction.
