Product 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 life2. Inflammable, free from toxic matter3. Anti-corrosion and resistance to aging4. Lower expansion and contraction5. Lower noise6. Aseismatic because of it's flexible and high tolerant body7. Anti-leakage and seep8. Easy to be installed9. Good design and appearancePipe 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 switchExternal 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: inflammableHydrostatic pressure test:Product Name Diameter mm Max testing pressure MpaNormal testing pressure MpaCentrifugal drainage pipe 50-200 0.8 0.42Centrifugal drainage pipe > 200 0.5 0.42 Mechanical & Chemical analysis:Tensile strength ≥ 180MpaBrinell hardness ≤ 260HBForce test No leakage in 5 minutes under stable pressureRing crush test ≥ 380MpaThermal expansion 0.0105mm / mk (0oC-100oC)Heat conductivity rate 50-60w / mk (20oC)No deformation of pipe with foreign heat under temperature 400oCNo corrosion of pipe because of medium with PH value 2-12Chemical analysis S ≤ 0.1 P ≤ 0.3 C:3.3-3.8 Si: 2.2-2.7 Mn: 0.4-0.7Note: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.About US:
