Cast iron pipes are manufactured by centrifuqal castinq process and pipe fittings by sand casting process. Our products quality is fully in accordance with the European Standard EN877, DIN19522 and other standards.
EN 877 is the product standard for cast iron drainage pipe systems DN 40 up to DN 600, This standard specifies product requirements and test methods to guarantee cast iron pipe system quality, dimensions and wall thickness, mechanica
properties (like water pressure, tensile strength and brinell hardness), appearance. Also EN877defines the coatings for epoxy cast iron pipes, fittings and couplings, making a difference between normal building drainage (installation within a building, in concrete or outside onto a building) and underground installation.
Why choose DS cast iron drainage pipe system?
Cast iron drain pipe system which fully meets the European standard EN877:2021, owns a wide range of advantages:
1. Eco-Friendly & Long Lifespan
- Made from 100% recyclable materials, saving natural resources.
- Can be reused for the same purpose without losing performance.
- Proven lifespan exceeding 50 years thanks to excellent mechanical properties.
2. Fire Protection
- Non-flammable and non-combustible—releases no gases or toxic smoke.
- DS pipe couplings with EPDM gaskets help control smoke during a fire and prevent its spread.
- Cast iron components can even be recovered and reused after a fire.
3. High Mechanical Strength
- Made of grey cast iron with flake graphite for high strength, wear resistance, and temperature tolerance.
- Excellent corrosion resistance and high damping capacity.
- Unlike uPVC/PVC, DS products do not soften, deform, or become brittle under intense temperature changes or sunlight.
4. Low Noise
- Dense cast iron walls block airborne sound, creating a silent drainage system.
- No costly sound insulation measures are needed.
- Ideal for hospitals, hotels, offices, and apartments. hotels, offices and apartment blocks
5. Anti-Corrosive Epoxy Coating
- All DS pipes and fittings are finished inside and out with a corrosion-resistant epoxy coating.
- Prevents fouling and corrosion, even in humid or tropical conditions.
- Resists household chemicals like organic acids and caustic soda.
- Smooth interior surface prevents blockages and allows solid waste to pass easily.
- Widely used worldwide in laboratories, hospitals, factories, and homes.
6. Easy to Install & Maintain
- DS couplings connect pipes and fittings using simple tools—quick and labor-saving.
- Highly durable, requiring minimal maintenance over the building’s lifetime.
- Ideal for locations where repair or replacement is inconvenient.
- When repairs are needed, simply remove the couplings and rubber gasket for low-cost, easy service.
