No-Hub Cast Iron Drainage system, pipes and fittings are complied to the requirements of CISPI Standard 301 or ASTM A-888.
All pipes used in this system are using the centrifugal casting process.
The pipes and fittings are connected with couplings. The couplings consist of a stainless steel shield, clamp assembly and an elastomeric sealing sleeve conforming to the requirements of ASTM C564.
Dimensions and tolerances (in inches) of spigots and barrels for hubless pipe and fittings.
Pipe may be with or without a spigot bead.
pipes and fittings are coated externally and internally with a bitumen coating or epoxy coating.
Characteristics of Pipework System:
•Durability exceeding expected life of the building.
•Resistance to corrosion from fluids and gases commonly found in a plumbing drainage system.
•Noncombustible and does not contribute to the spreading of flames.
•Resistance to abrasion.
•Ability to withstand temperature extremes.
•Ability to withstand traffic and trench loads.
•Low coefficient of expansion / contraction.
•Joints which resist infiltration and exfiltration.
•Strength and rigidity.
•Resistance to noise transmission.
