Product Desciption
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
Pipe sizes:
Internal coating and it's performance:
-- Material of coating: epoxy or coking bituminous
-- Thickness of coating: 120 microns
-- Resistance to salt solution(5%): no change under normal temperature within 30 days
-- Resistance to chemicals: no change in water (PH2-12) at 23ºC within 30 days
-- Resistance to temperature: no change in 95ºC water within 24 hours
-- Resistance to cold and hot water cycle: 1500 times at 15ºC-93ºC switch
External coating and it's performance:
-- Material: epoxy or red painting
-- Thickness of dry paint film: 40 microns up
-- Thickness of coating: 40 microns up
-- Adhesion: comply to ISO2409 Grade 2
-- Resistance to fire: inflammable
Hydrostatic pressure test:
Mechanical & Chemical analysis:
Note:
1. Free from impact during delivery and installation.
2. Protect inner and outer coatings against sharp articles.
3. Check whether there is block in pipe and fittings before installation,
If there is, clear it firstly.
4. Joints like clamp should guarantee no shape cracking, thread damage and gasket damage.
