The CSA B70 standard is a core Canadian national standard for Cast iron pipes, fittings, and means of joining. It specifies technical requirements for no-hub cast iron pipes, including dimensions, wall thickness, mechanical properties, and epoxy coating quality.
Why Choose Epoxy Cast Iron Pipe Compliant with CSA B70?
- Long-term Corrosion Protection The internal and external epoxy resin coating significantly improves resistance to acids, alkalis, and abrasion, offering a much longer service life than traditional asphalt-coated pipes.
- Low-Noise Drainage Cast iron has high material density, which effectively reduces water flow noise. This makes it an ideal choice for quiet environments such as hotels, hospitals, and high-end residential buildings.
- Fire Safety Epoxy cast iron pipes meeting CSA B70 are classified as Class A non-combustible materials, emitting no toxic smoke in the event of a fire.
- Reliable Connection The no-hub connection system, combined with stainless steel couplings and EPDM rubber joints, ensures easy installation and excellent sealing performance.
