The self-anchored ductile iron pipe adopts a special mechanical design to weld the ring to the socket end to achieve reliable anchoring performance, while retaining the flexibility of the joint, with good flexural performance, which can replace the function of the constraint block and realize the design without constraint blocks.

When considering durable piping solutions for residential, commercial, and industrial projects, UPVC (Unplasticized Polyvinyl Chloride) pipes and HDPE (High-Density Polyethylene) pipes have become the preferred choices worldwide.

An All Flange Tee is a specially designed pipe branch connection characterized by its defining feature: all three ports—both ends of the main pipe run and the perpendicular branch outlet—are equipped with flanges. This configuration distinctly differentiates it from other tee fittings that may feature threaded, socket weld, or plain ends.

The Y-type strainer stands as the most widely used mechanical filtration device in industrial piping systems, its name derived from the distinctive Y-shaped configuration of its housing. Its core function is to intercept solid particulate impurities within fluids (such as rust, welding slag, pipe scale, or process residues) through an internal strainer screen, thereby protecting downstream equipment (pumps, valves, flow meters, heat exchangers, etc.) from wear or blockage. The operating principle involves: fluid entering the strainer housing via the inlet, flowing through an angled cylindrical screen where contaminants are trapped on the inner surface, while clean fluid passes through the mesh openings to the outlet. Accumulated debris can be removed by manually or automatically opening the drain valve at the bottom.

Ductile iron pipes widely use flexible joints for connections. These joints allow the pipe to deflect and expand/contract within a certain range to accommodate ground settlement or temperature changes.
