Speedfit Barrier Pipe
Speedfit Barrier Pipe is manufactured to BS 7291
Parts 1, 2 and 3 Class S and is Kitemarked.
It is made up of 5 layers,
the centre of which is a
blue coloured oxygen
barrier which prevents the
ingress of air into the
system, thereby reducing
the eect of corrosion on
metal components.
Because of its low thermal
conductivity when carrying
hot water, Speedfit pipe
is cooler and therefore
safer to touch. Relatively
low heat loss through radiation means that a system
retains its heat longer and delivers hot water more quickly
and with less wastage than a metal system.
The pipe is available in coils and straight lengths. Pipe
markings are spaced to aid the making of a good
connection when using a Superseal Pipe Insert.
Pipework sizing
For general guidance on pipework sizing, please refer to
BS EN 806 and complementary guidance document
BS 8558, or the Institute of Plumbing Engineering
Services Design Guide. Speedfit Fittings are suitable for
pipes within ±0.1mm of nominal size. They can be used
with copper pipe to BS EN 1057 or Speedfit plastic pipe.
The Product Range List shows the fittings available for
reducing pipe diameters within the system.
Speedfit pipe is available in straight lengths and coils.
Pipe bending
Gentle bends can be made with pipe clips on either side
of the curve, positioned to maintain the bend radius.
Tighter bends can be
achieved by using the cold
forming bends shown on.
Internal Bending Springs
are available in 10mm to
22mm sizes.
It is also possible to bend Speedfit pipe using a standard
pipe bender. The pipe should not be heated with a
blowlamp or hot air gun.
Minimum bend radii for Speedfit pipe (BPEX and BPB)
are as follows:
Speedfit min radius
Pipe diameter
10mm 15mm 22mm 28mm
With cold
forming bends
30mm 75mm 110mm –
With clips 100mm 175mm 225mm 300mm
BPB min radius
Pipe diameter
10mm 15mm 22mm 28mm
With cold
forming bends
30mm 75mm 110mm –
With clips 80mm 120mm 176mm –
For bends of radii smaller than those shown, standard
elbow fittings are recommended.
