The cast iron pipe soil pipes are manufactured according to ISO***4, EN**7. ASTM and CISPI**1 Standards 
1. Long-lasting. More than **0 years life span. 
2. Smooth finish inner and outer interface. Excellent anti-seismic features, suitable for anti-seismic protection in high buildings. 
(1)Whatever axial deformation, within *5mm, causes no leakage. 
(2)Traverse vibration deflection reaches *1.5mm with no leakage. 
(3)Gently interfaced by lining neoprene rubber washer and stainless steel hoop, providing good seal and permitting vibration within *5 degree, causes no leakage. 
3. Centrifugally cast. Even wall thickness, fine structure, smooth surface, no casting drawbacks such as sand holes or mixed dregs. 
4. Low noise. These noiseless pipes provide residents with a quiet environment. 
5. Simple and convenient to install and maintain. Installed pipes are beautiful and decorative. 
6. Light weight. Compared with sand cast pipes, layout length increases ****0%. 
7. High strength. Resistent to breakage chemicals and weather.
