Description

Brief introduction:
This product is widely used in building drainage system because of it's excellent performance in noise suppression, fire resistance, low thermal expansion and chemical resistance. At the same time, it is solid and durable and easy to install. Drainage system include socketless centrifugal cast iron pipe, socketless fittings, joints and sealing ring.

Manufacturing method: centrifugal casting.

Product advantages:
1. Durability with long time service life
2. Inflammable, free from toxic matter
3. Anti-corrosion and resistance to aging
4. Lower expansion and contraction
5. Lower noise
6. Aseismatic because of it's flexible and high tolerant body
7. Anti-leakage and seep
8. Easy to be installed
9. Good design and appearance
