Import Dn125 Twin Wall/Single Schwing Concrete Pump Elb — Buy in Bulk from Supplier in China

The DN125 twin wall/single Schwing concrete pump elbow is a dual-layer component with an outer structural shell and an inner wear-resistant liner, designed for high-pressure concrete delivery systems. It is engineered for compatibility with Schwing and similar pump models, featuring a 125mm nominal bore and a 90-degree bend with a standard 275mm centerline radius. The twin-wall construction enhances durability under abrasive conditions while reducing overall weight compared to solid high-chrome fittings.

The inner liner is typically made from high-chrome cast iron or tungsten carbide composite, while the outer shell is constructed from low-alloy carbon steel such as Q345. This design provides impact resistance and structural support without the cost of a fully wear-resistant body. Standard tolerances for such fittings include ±0.5mm on outer diameter and ±1.5° on bend angle. The product is available in 45-degree and 90-degree variants, with both long and short radius options to suit different pipeline layouts.

This elbow is primarily purchased by construction contractors operating concrete pumps in high-rise buildings, bridges, and tunnel projects where downtime is costly. Buyers often replace these components as part of routine maintenance cycles. Trade terms are not specified in the listing, but export packaging is likely palletized with anti-rust protection. Buyers should confirm whether the product is manufactured in-house or sourced from third-party foundries, as this affects consistency and warranty.

Hebei Dayu Feiteng Wear Resisting Pipe-production Co., Ltd. is based in Shijiazhuang, China, with a harbor trust tier indicating verified export experience. The company name suggests a focus on wear-resistant pipe production, implying involvement in manufacturing rather than pure trading. The listing does not specify production facilities, workforce size, or certifications, and response metrics are zero, indicating limited buyer communication capacity.

There is no mention of in-house casting capabilities, quality control procedures, or client references. The supplier does not claim ISO certification, third-party testing, or R&D investment. While the name implies manufacturing, the absence of technical documentation or production details suggests the entity may act as a trader consolidating components from multiple foundries. Buyers should treat this as a sourcing partner with unverified production control.
