What does a higher SDR class mean in practice?

Thermoplastic materials are widely used for the transport of water, gasses and other fluids. The outstanding performance, durability and physical-mechanical characteristics as compared to traditional pipe materials such as steel, copper and in some cases even concrete, have generated an increasing interest in the use of thermoplastic materials over the past decades.

LyondellBasell is one of the worlds’ largest suppliers of thermoplastic polymers (including PB-1) for pressurized and non-pressurized pipe applications.

Benefits, such as being corrosion free, light weight and offering easy installation together with reduced maintenance costs make thermoplastics technically and economically attractive, particularly in demanding pressurized hot and cold water systems.

Unfortunately, there are many examples of pipe systems that did not fulfil the design expectations; Have you ever come across corroded pipe systems that started to leak or even burst long before their expected lifetime? Or, have you experienced premature rupture of plastic pipe systems, even when they were thought to be properly designed? And have you thought about the financial impact of unplanned maintenance or even complete shutdowns over the lifetime of the pipe system?

The subject of this webinar is Polybutene-1 (PB-1), a thermoplastic material which has been in the market for more than 40 years and which is particularly used in demanding pressurized pipe systems. Through an easy to understand step-by-step approach the extraordinary characteristics of PB-1 are compared with the well-known and widely used thermoplastic alternatives.

PB-1 is the most technically advanced thermoplastic material for the transport of hot and cold water, offering the opportunity for reduced installation and operational costs over the lifetime of the pipe system.

This webinar will provide you with insights when considering PB-1 for your next pressurized hot and cold water pipe system or infrastructure project.

The Bottom Line

Specifying PB-1 piping systems offers:

  • Substantial material saving opportunities, while at the same time increasing the capacity of the system
    – thinner walls
    – increase of the available inside cross section area
  • A higher degree of design freedom for projects including District Energy grids
    – opportunity for using smaller outside pipe and fitting diameters
  • A clear opportunity for reduced integral installation cost and operating cost
    – smaller pipe support frames
    – use of less insulation material
    – smaller pumps running at reduced energy consumption
    – lighter overall weight for easier handling and lower shipping costs
  • The capability to utilize all available jointing techniques
  • Best in class acoustics including the lowest level of water hammer
  • The ability to be fully recycled

Polybutene-1 is often referred to as Polybutene, Polybutylene, PB-1 or PB.

Polybutene-1 is not sold by PBPSA members for use in pipe applications intended for use in North America, and those parties require their customers or distributors not to sell products made from PB-1 into pipe applications for North America.
