In case of using pipes to transfer usable hot water - steel galvanized pipes according to DIN-2444 are used.
All pipes used in production have metallurgical certificate for parameter compliance with standard requirements.
In a preinsulation technological-preparatory cycle, steel pipes are cleaned by means of shot peening, which significantly increases adhesion of polyurethane foam with a steel pipe.

Rigid polyethylene PEHD pipes, according to standard PN-EN 253, galvanized sheet pipes according to PN-81/H-92125, coiled spirally (SPIRO type), aluminium sheet pipes manufactured according to PN-87/H-92833, are used as casing coat depending on needs. Polyethylene pipes used to improve adhesion of polyurethane PUR foam with a casing coat are activated by means of electro-crowning method. Reputable national and foreign companies, ensuring highest quality, are suppliers of materials and resources assigned to production of preinsulated products.
