for use in mining and industry
MATERIAL polyethylene liner, steel pipe
APPLICATION in rooms and underground workings classified as “a”, “b”, “c” levels of methane explosion hazard and “A” or “B” levels of coal dust explosion hazard and other industrial plants
RANGE from DN88.9 to DN610 mm, pressure to PN160
Two-layer steel and plastic pipes and fittings, consisting of an external steel pipe and an internal polyethylene liner tightly fitted to a steel pipe or fitting. Black or galvanized steel pipes can be seamless or seamed according to European standards. Pipe ends may be solid, loose, or specially made by roll or cut grooves for Victaulic-style joints. The thickness of the steel pipe wall and the thickness of the polyethylene liner depend on the pressure in the installation and the type of transported medium.
STAL/PE pipes and fittings can be made with a polyethylene liner in the following version:
Pipes are designed for the construction of transport installations:
Before using STAL / PE pipes for the transport of chemical agents, the resistance of polyethylene and the material of the seals to this chemical agent should be taken into account. STAL / PE pipes cannot be used for the transport of methane in underground workings of hard coal mines. ELPLAST + can make internal polyethylene lining of steel pipes and fittings supplied by the customer.
