Buteline Polybutene-1 (PB-1) pipe for the United Kingdom has a barrier layer applied during extrusion to prevent the ingress of air into the system, which can cause corrosion of metal components of circulated water heating systems (such as radiators and boilers). This barrier layer is mandatory in the United Kingdom.
Polybutene-1 (PB-1) is not a hybrid material and was specifically developed for use with hot and cold potable water. It can withstand high temperatures and pressures. It is a proven solution for the conveyance of clean healthy drinking water.
A thin layer of Ethylene Vinyl Alcohol (EVOH) is applied during the manufacture of pipe by co-extruding the EVOH together with a layer of specially formulated adhesive, directly onto the external surface of the pipe. This prevents oxygen transfer from the external air to the water carried within the pipe. EVOH is particularly suited to protecting plumbing pipes from oxygen infiltration due to its ability to maintain its barrier properties over a very wide temperature range.
Buteline pipe meet the exacting British Standard BS 7291 and is fully WRAS approved.
Buteline offer lengths and coils of grey Polybutene-1 (PB-1) pipe in 10mm, 16mm, 22mm and 28mm sizes.
25m and 50m coils of 10mm Polybutene-1 (PB-1) pipe are available in white.
