Buteline manufactures pipes in various sizes up to and including 32mm from two materials. Polybutene-1 (PB), which was developed over 40 years ago for use as hot and cold domestic plumbing pipe, is a proven solution for the conveyance of clean healthy drinking water. In addition, Buteline has adopted Polyethylene as a cost effective alternative plumbing material for cold water only installations. Polyethylene is accepted worldwide as one of the preferred materials for the transport of potable water, and has been in service for over 60 years.
The pipe is manufactured with Buteline equipment, designed and engineered by Buteline's equipment division. It has the capability to run 5 metre lengths of pipes and to automatically cut Quality Assurance samples, ensuring pipe quality is monitored and maintained throughout the manufacturing process.
Buteline's manufacturing equipment and technology ensures the
manufacture of consistently high quality pipe. Combined with Buteline's laboratory testing, this ensures that all pipe exceeds
even the most stringent world standards.
Buteline Pluming System has won world acclaim for their advanced engineered design and capabilities.
