      STRAUB-PLAST-PRO
Axial restraint connection of PE80 and PE100 pipes
Axially restrained full set allowing a quick and simple installation of pressure pipes made of polyethylene(PE). The full sets are available for pipes in dimension SDR 11 (63.0 - 110.0 mm, PN16) and SDR 17 (>110.0 -355.0 mm, PN10). STRAUB- PLAST-PRO is particularly suitable for water, waste water, industrial plants and maintenance applications.
STRAUB-PLAST-PRO is applicable, whenever pipes cannot be connected by conventional technologies, like electro fusion. The unique full set offers the great advantage that pipes can easily be connected, without the need for an external power supply and pipe end preparations, even under demanding external circumstances.
The pipes made of PE 80 or PE 100 are connected with a combination of liner and two connectors. STRAUB-PLAST-PRO is highly resistant to corrosion, thanks to the usage of first class materials.
PE pipes with added protective layer and diffusion barrier
layer are normally used, when drinking waterlines have to be installed in contaminated soils. If the pipes are connected in a conventional manner, it is essential that the aluminum layer is removed. This operation is not necessary if STRAUB-PLAST- PRO will be used. STRAUB-PLAST-PRO connects such barrier layer pipes easily and safely without any pipe end preparation.
PE80 and PE100 pipes according to DIN 12201 / DIN 8074
