A range of halogen-free, flame-retardant, anti-static (FRAS) pressure pipe has been released by Calair for use in underground coal applications and methane extraction.

The Australian-made pipe is non-corrosive and tested to AS 1180.13A and AS1180.10B.

Calair boasts its new pipe is eight times lighter than equivalent steel piping and can be joined with bronze alloy compression fittings.

Calair managing director John McNab said the new pipes were a result of 10 years of research and development.

The new formulation is designed to overcome hurdles in producing halogen-free and flame-retardant pressure pipe without degrading the product’s overall performance, including impact resistance or pressure capability, McNab said.

Capable of handling typical pressures of 20 bar or more, the low toxicity FRAS range produces no corrosive or toxic flue gases in the event of a fire.

The pipes are colour-coded relating to the content identification of pipes, conduits and ducts, and comply with international safety standards, such as aqua for compressed air and green for water.

The pipes are available in sizes from 12.5mm to 100mm.
