Permissible operating overpressures

When using aquatherm PP-R pipes in heating or air conditioning systems, the pressure and temperature conditions according to the table “Permissible operating pressures” are valid. With regard to pressure and temperature, the operating conditions for pipes and pipe connections are to be based on the following table. These values refer to drinking water installations based on a fictitious service life of 50 years.

 

Operating overpressure Temperature Annual operating hours
Cold water 0 bar – 10 bar
faltering		 ‘ 25°C 8.760 h
Hot water 0 bar – 10 bar
faltering		 25°C – 60°C 8.710 h
    60°C – 85°C 50 h

 

The permissible pressures were determined with regard to the special conditions to which piping components in drinking water house installations are exposed.

Limiting factors such as increased flow velocities, the use of disinfectants, increased levels of oxygen, etc. were taken into account by applying appropriate safety factors.

For fittings made of butt-welded pipe segments, a weakening coefficient of 0.75 applies (reduction of the table values by 25%).

Comparision of the water content per meter

SDR = Standard Dimension Ratio (diameter/wall thickness ratio)
S = Single-layer pipe structure
MF = Multi-layer pipe structure – Fibre-reinforced
MF RP = Multilayer pipe structure – fibre-reinforced – with increased compressive strength

Fire load

The values required to determine the fire load within a fire compartment are derived from the sum of all combustible materials located in that area. The calculated verification of the combustion heat V [kWh/m] of a fire compartment in the event of a fire depends on the dimensions and materials.

Calculation basis aquatherm PP-R pipes made of PP-R is the lower heating valueHu 

= 12.2 kWh/kg (according to DIN V 18230 T1) and the material mass mPipe [kg/m].

For the aquatherm fibre composite pipes the integrated layers of fibres are additionally considered.

Depending on the calculation method, the fire load is calculated taking into account the burn-up factor. This as mFactor  is 0.8 for polypropylene.
