Chemkor Pressure pipelines Bend 11° with socket, uPVC, SDR 26, 1,0 MPa, d - 315 [Code number: 2181062]
Details
|
2181062 |
69 064 rub |
Purpose of application:
- For domestic and drinking water supply
- For residential and industrial buildings, as well as agricultural enterprises
- For industrial pipelines intended for the transportation of gases and technical liquids, semi-finished products, raw materials, industrial waste and other materials to which PVC-U is chemically resistant
- For vertical internal gutters
- For pressure sewerage (if it is not possible to divert sewage by gravity)
Characteristics:
- High resistance to UV radiation - under the influence of ultraviolet, the physical and mechanical properties of the material do not change;
- Resistance to microorganisms, fungi and bacteria;
- Fast installation;
- Socket connection (sealing ring made of EPDM);
- High resistance to alkalis, acids and surfactants;
- The temperature of transported liquids can vary from the freezing point of the effluents themselves to +60 °C (a short-term increase to +95 °C is possible);
- The ignition temperature is +482 ° C - it does not melt, the material is almost non-toxic, does not form burning drops, practically does not emit smoke;
- Refers to the flammability class G1 (GOST 30244-94);
- Warranty period: 2 years from the date of manufacture (if the rules of transportation and storage are observed);
- Service life: up to 100 years.
It is painted in grey.
The working pressure is 1,0 MPa.
