Designed for industrial compressed air pipe applications

DuraplusTM Air-Line pipe is corrosion-resistant and features metal-to-ABS special adapter fittings, single and multi-port wall brackets, high-efficiency dropper bends, and blue color coding for easy identification. Compressed air, a major source of industrial energy, is being used increasingly in both the manufacturing and processing industries. Its distinct advantages of cleanliness, flexibility, safety, and economy of use (compared with other energy sources) are fully exploited.


DuraplusTM Airline is manufactured from a specially formulated Acrylonitrile Butadiene Styrene (ABS) blend that has a high-performance co-extruded liner which greatly enhances its mechanical and chemical properties. DuraplusTM ABS Air-Line fittings are manufactured using an alloy blend of ABS and liner material, ensuring high performance of the whole system. DuraplusTM ABS Air-Line is designed for industrial compressed air pipe applications such as:

  • Plant air
  • Ventilation
  • Valve actuation – control systems
  • Food and beverage – CO2 delivery
  • Robotic installations

DuraplusTM ABS Airline is designed for industrial compressed air pipe applications where the extremely high impact resistance and ductility of the material offer some insurance against internal and external shock loadings and site abuse conditions. Its unique combination of ABS properties – non-toxicity, purity, corrosion and chemical resistance, toughness, low hydraulic resistance, and the ability to perform over a wide temperature range of 40°F – 120°F (4°C – 49°C), ensures excellent in-service performance and system life.

The pipe shall be manufactured from an Acrylonitrile Butadiene Styrene (ABS) blend, with a co-extruded liner. Fittings shall be manufactured from an ABS blend.

Material for both pipe and fittings shall be designed with a 2 to 1 safety factor for a 30-year lifespan when operated under continuous pressure. Pipe and fittings are capable of withstanding a continuous working pressure of 185 psi at 73°F (1275 kPa at 23°C) in accordance with ASTM D2282 and also carry a DIN 4102-B2 fire rating.

The material shall have an Izod impact resistance value of no less than 8.5 ft. lb/in at 73°F when tested in accordance with ASTM D256, method ‘A’. The pipe bore contains a co-extruded liner and fittings are manufactured using an alloy blend of ABS and the liner material.

Pipes shall be manufactured by IPEX and designed in metric sizes that comply with the dimensional requirements of DIN 8062, and ISO 161/1.

Fittings shall be of the socket type, designed for solvent welding as supplied by IPEX.

Fittings shall be designed and manufactured to withstand the continuous pressures applicable to the maximum pressure rating of the pipe. The sockets and fittings shall have a 0.50° taper, the diameter decreasing from the mouth to the root.

The valve body, stem, ball, and unions shall be made of Duraplus ABS compound which shall meet or exceed the requirements of cell classification 43234 according to ASTM D3965.

Ball valves shall be a double-blocking type with O-ring cushions under the PTFE seats, in-line micro-adjustment capability, and incorporate a spanner wrench in the handle.

The valve body shall also be made of glass-reinforced polypropylene (GRPP) obtained from homopolymer polypropylene (PPH).

The valve disc shall also be made of ABS compound.

All butterfly valves shall have non-wetted stainless steel shafts and a wafer or lug design with ANSI 150 flange connections. The liner shall completely isolate the valve body from the process flow and act as a flange gasket on both sides of the valve.

All joints shall be made with Blue Duraplus Air-Line ABS solvent cement as supplied by IPEX. The solvent cement shall be designed to withstand continuously applied pressures up to 185 psi at 73°F

The design and installation of ABS pressure systems shall be performed in accordance with the recommendations detailed in the Handling and Installation section of the DuraplusTM Air-Line System Technical Manual and in local and national regulations where applicable. To ensure the full integrity of the completed system, all components shall be supplied by IPEX.
