Features of polybutylene pipes (PB pipes)

Semi-permanent life-span

PB pipes are semi-permanent as they provide higher tensile strength, rupture-resistance, abrasion-resistance, heat-resistance and durability, and especially suitable for the domestic usage as they are resistant to low temperatures when compared with other materials.

Corrosion-resistance

As the PB pipes are not to be corroded by concrete and salt, they are usable for the curing of concrete as well as for undergr ound piping work, They will not suffer any corrosion or rust even in a case where chemicals are used. Compared with other products with other materials, the PB products provide excellent chlorine-resistance, making them suitable as the piping ma terials for the water supply.

Heat-, pressure- and creep-resistance

PB pipes are superb in terms of elastic modulus, making them strongly resistant to breakage due to cold weather, as well as excellently resistant to heat and low temperatures. They are also excellent in terms of creep-resistance compared with other resins.

Light and flexible

PB pipes are good in terms of light weight and bending properties, making it easy to transport and work with them in a tight space. As they can be bent smoothly, they provide superb effects when used for the piping work for heating floors.

Suitable for the centralized heating

PB pipes are resistant to a wide range of temperature difference and pressure, making them suitable for the centralized heat ing system of high temperature and pressure.

Convenient workability

PB pipes are an innovative piping system that can be installed simply without tools, highly contributive in reducing the constr uction period and saving labor and construction costs as well.
