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

Cast iron soil fittings from Richang Qiaoshan Trade Co., Ltd. are manufactured to meet ASTM A888 and EN 877 standards, with nominal diameters ranging from 50 mm to 300 mm. These fittings include elbows, tees, wyes, and reducers, all cast from ductile iron with a minimum tensile strength of 420 MPa and elongation of at least 10%. The internal surface is machined to a smooth finish, reducing flow resistance and minimizing buildup in wastewater systems.

The material composition conforms to standard ductile iron grades with magnesium-treated nodular graphite, providing improved impact resistance over traditional gray iron. Wall thicknesses follow standard pressure ratings for gravity drainage systems, typically 5.5 mm for 100 mm diameter and proportionally thicker for larger sizes. These fittings are coated with bituminous or epoxy-based internal and external protection, suitable for burial in aggressive soils or high-moisture environments. They are not galvanized and are not intended for pressurized systems.

These fittings are primarily purchased by civil contractors, municipal utility suppliers, and commercial builders in Southeast Asia, the Middle East, and Eastern Europe for sewer and stormwater infrastructure. Orders are typically placed in container quantities, with standard packaging in wooden crates or bulk pallets. Lead times average 30 to 45 days after deposit, and trade terms commonly include FOB Qingdao or CIF destination port, with payment via T/T or L/C.
