Materials
All materials comply with RoHS directive and are Halogen and Cadmium free:
Triple layer pipe
Fittings made from grey, RAL 7037 PP-C (Polypropylene Co-polimer).
Method of connection:
All products are connected by means of push-fit insertion, with single-lip high quality seals made of SBR-NR, for guaranteed sealing and leak-proof performance.
Pipe markings
On each pipe, the following details will be clearly printed at least once every meter, with indelible ink: Producer – HULIOT, system type, dimensions, materials, stiffness level, date of manufacture and Standards Institute symbols.
Fittings markings
Every fitting will marked with all required information as follows: Producer – HULIOT, system type, dimensions, materials, stiffness level, number of the applicable standard and category of application, date of manufacture and Standards Institute symbols.
Temperature performance
- Hot water resistance:
- 95°C for long term (3000 hours/50 years = 10 min/day).
- 60°C for permanent load (90,000 hours/50 years = 5 hours/day).
Chemical resistance
System materials are resistant to aggressive discharge media in the range of pH 2 to pH 12 according to DIN 8078. As listed in the chemical resistance list. Download PDF version of the chemical resistance list.
The list specifications used as a general guidance as to the chemical resistance of the material and cannot simply be applied to all applications. They shall not be used as a guidance to determine the possible effects on the reagent. Mechanical behavior can be impaired in cases where tension and the presence of chemicals occur simultaneously (tension-fracture corrosion).
Fire resistance
The HT system tested and certified by SKZ and MPA NRW institutes according to DIN 4102-1 classified B2 or B1.
