LINEAR THERMAL EXPANSION CALCULATOR

Determine the linear thermal expansion when designing PP-R piping systems to account for changes in pipe length.

Head Loss Calculator

The pressure loss tools gives the head loss and flow rates of the pipe based on the desired flow rate.

Permissible working pressure

Using aquatherm PP-R-pipes for heating or air conditioning applications the pressure- and temperature conditions according to table “Permissible Working Pressure” are valid. The following table shows the operating conditions related to pressure and temperature as a basis for pipe and pipe connections. These figures refer to potable water installations based on a theoretical service life of 50 years.

The determination of the allowable pressures resulted from the specific conditions to which pipe system components in the drinking water domestic installation are exposed to.
Limiting factors such as increased flow rates, the use of disinfectants, increased content of oxygen, etc. were considered by the use of the appropriate safety factors.
For fittings of butt-welded pipe segments a reduction factor of 0.75 (reduction of the table values by 25 %) is effective.

Fire load

The values required for determining the fire load within a fire section are calculated from the total of all flammable materials located within this area. The calculation for establishing the combustion heat V [kWh / m] for a fire section in the event of an outbreak is dependent on dimensions and materials.

The basis used for the calculation of pipes made of PP-R is the lower calorific value

Hu = 12,2 kWh/kg (as per DIN V 18230 T1) in conjunction with the mass of material mpipe [kg/m].

The integrated layers of faser in aquatherm faser-composite pipes also are considered.

Depending on the calculation procedure, the fire load is worked out with reference to the burn-up factor. This value is designated as mFaktor and is taken as 0.8 for polypropylene.
