Chemical pipes those have high requirements concerning corrosion, temperature and pressure are produced from glass fiber reinforced with thermoplastic liner.
Design of pipes according to SFS 3274 and collars according to SFS 2617. Dimensions of pipes made of PRP-Plastic Oy are in table. Dimensions of collars made of PRP-Plastic Oy are in table.
The pipes does not weight much, requires no maintenance and is easy to clean. Due to the smooth internal area the pipe resistance is low.
Depending on the working conditions thermoplastic liner is chosen:
PVC __ poly (vinyl chloride)
PP____ polypropylene
PE-HD_ polyethylene, high density
PVDF__ poly (vinyldene fluoride)
ECTFE_ ethylen / chlortrifluorethylen
FEP___ perfluoro (ethylene / propylene)
PFA___ perfuoro alkoxyl alkane
Due to the excellent physical properties of GRP and the chemical resistance of thermoplastic liner, these pipes can used in higher temperature and pressure.
The main applications are:
- chemical industry
- textile, paper and chemical pulp industry
- water treatment systems
- industrial pickling plants
- electrotype plants
- chlorine electrotype plants
- power plants
