Minimum requirements for a pipe rail system
The rails (usually heating pipes) must have an external diameter of between 51mm and 45mm
and a wall thickness of at least 2mm. The minimum material specifications for the pipes is as
follows: Steel 37 (S235JR). The supports for the pipe rail system must be no greater than 1.25m
distance from each other. Where piping with a diameter of 45mm is combined with a track width
of 42cm, the distance between the supports should be no greater than one metre. Pipe rail
supports are used that correspond with, or are at least equal to the following specifications:
steel bottom plate 1.5mm thick with a stiffening profile - minimum bottom plate width of 115mm
and a length such that the bottom plate sticks out at least 70mm from the two upright supports
that carry the pipes. The centre to centre distance between the pipes should be at least 42cm.
The pipes must be stable, accurately installed and level with a maximum slope of no more than
2
either in length or in width. The pipes must also be properly attached to the supports and the
concrete track. Loose fitting pipes may not be used! A soil test bore should be carried out using
probing equipment (see policy regulation according to the health and safety catalog in force in
the Netherlands). It should have a so-called cone value on the top layer of more than 0.4 Mpa
(62 psa).
Employing a pipe rail system that is not described in the policy regulation according to the
health and safety catalog in force in the Netherlands is permitted provided that a stability test is
carried out in accordance with the pipe rail system policy regulation according to the health and
safety catalog in force in the Netherlands and where it appears that the combination of pipe rail
trolley and pipe rail system in question is in fact stable. Furthermore, the supports for this
exceptional pipe rail system must have a maximum spacing of one metre and the alignment
variation in both length and breadth must not exceed 2 degrees.
The tubes are similar or at least equal to the specifications given in the table below.

Quality steel 37 (St37)
Wheelbase between 62.5% and 125% of the support distance.
All values for other pipe and tube rail supports should be calculated separately.
