Buteline Polybutene-1 pipe
|
All pipe in New Zealand is manufactured out of Polybutene-1 (PB-1) using equipment designed and built by Buteline's engineering division. The Pipewinder (pictured right) automatically cuts quality assurance samples which, in addition with Buteline's laboratory testing, ensures consistent production of high quality pipe that exceed even the most stringent world standards. Buteline Polybutene-1 pipe can withstand high temperatures and pressures, is manufactured to meet the exacting Australian and New Zealand Standard AS/NZS 2642, and complies with the AS/NZS 4020 Food Grade Standard.

Buteline manufacture lengths and coils of grey Polybutene-1 (PB-1) pipe in 15mm, 20mm and 28mm sizes.
20mm Recycled Water pipe (in lilac colour) is also available.

Buteline pipe is tested to exacting national and international requirements with regards to compatibility with fittings, resistance to leakage when subjected to bending, resistance to pull out of assembled joints (as proven by The Buteline 'Pipe Pull' Demo -- you can literally tow your car using Buteline pipe), as well as thermal and pressure cycling.
Short term tests are carried out at a calculated pressure based on a given hoop stress pressure depending on the duration of the test. The tests are carried out at 95 ± 1°C for durations of 1 hour and 170 hours.
Long term tests are carried out based on the hoop stress pressures given for operating temperatures between 20°C and 95°C.
Main Advantages of PB-1 Pipe
- Increased flexibility (ie: Less fittings required = save $$ and installation time), lightweight, easier to install
- Does not corrode, and no scale build-up
- Superior strength (40% stronger than PE-X, and almost double the strength of PP-R and PE-RT, as published in ISO9080 evaluation of PE-RT)
- Reduced wall thickness gives larger pipe internal diameter resulting in higher flow rates whilst lowering energy costs
- Silent operation, virtually no water hammer
- Excellent resistance to creep
- The best choice for plumbing in climates where freezing conditions are possible
