Polybutene pipes enjoy a broad acceptance among engineers, architects, planners, building contractors, installers and homeowners for heating, cooling and potable water installations. That’s because the ease and reliability of installation in combination with its exceptional resilience over a long lifetime make polybutene (PB-1) an ideal choice of carrier pipes for both indoor and outdoor applications.

Polybutene pipes for universal, reliable service

PB-1 carrier pipes ensure uncomplicated efficiency in various climates and applications worldwide, from indoor cooling systems in Panama to large-scale potable water networks in the Netherlands. It is the best in class for energy efficiency, pressure and temperature rating, making it ideal for pressurized hot and cold water installations.

50+ years performance with PB-1 carrier pipes

The high resistance of polybutene to stress, corrosion, frost, chlorine and aggressive water ensure a lifetime from 50 – 100 years (depending on the application). In domestic applications, polybutene pipes absorb and suppress sound and are not subject to 'water hammer' particularly in areas with high water delivery pressures.

Assortment

Our flexible range of polybutene carrier pipes is available in OD 16 to OD 110 mm, in sticks (3m or 6m) or coils up to 75m. For diameters of OD 125 up to 225mm, our PB-1 pipes are semi-flexible and available in sticks of 6m and 12m, depending on the diameter. We also offer PB-1 pipes with oxygen barrier (up to OD 90mm) to avoid corrosion with metallic parts in boilers and control manifolds.

Simple and safe installation with PB-1 carrier pipes

The flexibility, weldability and light weight of polybutene pipe systems have revolutionized how hot and cold water systems are installed. It requires no bending tools, no naked flame, and no fluxes or chemicals. Electrofusion, poly-fusion and butt-fusion welding techniques ensure homogeneous, durable and record-breaking system welding in respect to ease, speed and reliability of installation.

Prefabrication for large-scale networks

For district applications such as potable water networks, Thermaflex can deliver fully prefabricated and factory-tested polybutene networks. This reduces the amount of on-site welded connections by 70% of traditional designs. This comes with multiple benefits:

  • Minimize installation risk
  • Reduce handling and trench time
  • Stay on budget and planning
  • Control installation and overhead costs

Comprehensive installation support

  • Welding training
  • On-site installation support
  • Installation manuals
  • Pre-check of design and parts during order
  • Tools & accessories (discover them here)
