MULTITHERM - your partner for many years has been manufacturing plastic pipes and fittings.
MULTIPLAST - to inspire we are still generations of engineers, architects and builders.
Use: For sanitary, heating, industry, cooling water, compressed air, agriculture and water treatment plants.
Scope: In accordance with ÖNORM B 5174 bar at 20 ° C / 20 and at 60 ° C / 10bar
Example: Change in pressure and temperature conditions can be read because of the creep curve, the operating time.
Processing: The installation of MULTI PLAST is the traditional method and installation is simple, fast and clean. The combination technique is performed by Polyfusion socket fusion with metal transition pieces.
Dimensioning according to ÖNORM B 2531/2
| sampling point | flow rate | demand value | ||
| (Qs = l / s) | (Qm = l / min) | (BW) | ||
| bath tube enema, bath shower | 0,400 | 24,0 | 2,50 | |
| shower | 0,250 | 15,0 | 1,00 | |
| basin, sink | 0,170 | 10,5 | 0,50 | |
| cisterns, urinals | 0,125 | 7,5 | 0,25 | |
| sink, kitchen sink | 0,250 | 15,0 | 1,00 | |
| handshower | 0,175 | 10,5 | 0,50 | |
| dishwasher | 0,250 | 15,0 | 1,00 | |
Dimensions: after addition of the flow rate (taking account of simultaneity) or addition of the already designed load value, the pipeline will impact on pre-dimsioned moderate. From economy to the flow velocity 1 m / s to be, out of deference to the flow noise but
2 m / s are not exceeded. In special cases, max. 3 m / s are permitted.
Pressure drop:
The diagram can be determined, the pressure loss in pipes
MULTIPLAST diagram is valid for water at 10 °C.
For the temperature range 0 - 70 ° C is the calculated or to multiply the pressure drop-table-value taken from the respective temperature factor from the two tables. For the individual resistances of fittings can approximate the values in the table below. The individual resistors are available for connections to determine lump sum. As a guideline, it can be assumed to 5% on the total pressure loss, a surcharge of 3%.
