Import Dn125 Concrete Pump Schwing Concrete Pipe Elbow — Buy in Bulk from Supplier in China

The DN125 Schwing concrete pipe elbow is a 90-degree curved fitting designed to redirect concrete flow in high-pressure pumping systems. It is manufactured from high-strength ductile iron with a wall thickness of 10 mm, conforming to ASTM A536 Grade 65-45-12. The internal bore is precisely machined to 125 mm diameter with a smooth finish to minimize friction and reduce wear. Each elbow is engineered to match Schwing pump system flanges, ensuring direct compatibility without adapters.

The product is cast using a sand-mold process with controlled cooling to prevent porosity. The surface is treated with anti-corrosion coating to resist concrete slurry erosion. Typical industry elbows have a bend radius of 1.5 times the nominal diameter, which is 187.5 mm here. The fittings are not plated or galvanized; instead, they rely on dense iron structure and protective paint for longevity. Packaging is in wooden crates, with 60 pieces per crate, as stated in the listing.

This elbow is purchased by large-scale concrete contractors, tunneling firms, and infrastructure builders in Southeast Asia and the Middle East. Buyers typically order in multiples of 60 pieces to match shipping container loads. The product is used in both stationary and trailer-mounted pumps. Trade terms are not specified, but FOB Qingdao or CIF Port of Destination are standard. Buyers should confirm the material certification and surface hardness test results before shipment.

Shandong Shengbang Concrete Pump Parts Co.,Ltd is located in Liaocheng, Shandong Province, China. The supplier is listed as imported with harbor trust tier status, indicating verified export documentation. No company history, production capacity, workforce size, or client references are disclosed. The supplier does not claim ISO certification, nor does it provide response rate or contact availability, suggesting limited buyer communication infrastructure.

The company specializes in concrete pump spare parts, particularly elbows, pipes, and wear plates. It does not manufacture pumps or hydraulic systems. The product line appears focused on Schwing-compatible components, indicating a niche supply role. No factory inspection reports, quality control procedures, or testing equipment details are provided. Buyers should treat this as a component supplier without public operational transparency.
