Import Cast Iron Soil Pipe — Buy in Bulk from Supplier in China

The No Hub Cast Iron Soil Pipe supplied by Richang Qiaoshan Trade Co., Ltd. is manufactured to meet ASTM A888, CISPI 301, and EN 877 standards, with nominal diameters ranging from 50 mm to 300 mm and wall thicknesses conforming to standard pressure ratings for gravity drainage systems. Each pipe is cast using grey iron with a minimum tensile strength of 150 MPa and features a smooth internal bore to reduce flow resistance. The no-hub design allows for flexible jointing using rubber gaskets, eliminating the need for traditional lead or cement seals.

The material composition follows standard grey cast iron grades used in plumbing, with carbon content between 2.8% and 3.6% and silicon levels from 1.8% to 2.8%. This ensures good machinability and vibration damping, critical for noise reduction in high-rise buildings. Surface finish is typically sand-cast with a light oil coating to prevent rust during transit. These pipes are not galvanized or coated with epoxy, as the inherent corrosion resistance of cast iron in soil environments is sufficient for long-term performance.

These pipes are primarily purchased by contractors in commercial construction, municipal infrastructure projects, and large residential developments across Southeast Asia and the Middle East. Buyers commonly order in full container loads with packaging on wooden pallets, secured with steel bands. Standard lead time is 30 to 45 days after order confirmation, and trade terms are typically FOB Qingdao or CIF destination port. Buyers should confirm the pipe’s certification documentation matches the referenced standards before shipment.
