​While UPVC pipes form the backbone of modern plumbing networks, it's the UPVC accessories that give these systems their versatility and longevity. These meticulously engineered fittings—elbows, couplings, valves, and adapters—serve as the critical junctions where direction changes, flow control, and system integrations occur.

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 pipe, with its high strength, high toughness, excellent pressure and impact resistance, good corrosion resistance (combined with standard protective coatings), reliable sealing, long service life, and outstanding seismic performance, has become an indispensable "artery" in modern urban and industrial infrastructure. It primarily serves critical areas such as water supply, drainage, fire protection, industrial fluid conveyance, and hydraulic engineering. It is a fundamental material ensuring public safety, effective water resource utilization, and the normal functioning of cities.

In industrial production and infrastructure construction, carbon steel pipes have become the core carrier for the transportation of liquids, gases and other media with their high strength and wide adaptability. Their performance stability and cost advantages make them occupy an irreplaceable position in many fields and are important basic materials to support industrial operations and engineering construction. ​

​All those who are engaged in engineering procurement know that Carbon Steel Pipes and Stainless Steel Pipes are the two most commonly used metal pipes. Although they both look like iron pipes, their performance and price are quite different. Choosing the right one can save a lot of money.

The core sealing of a gate valve relies on the tight fit between its wedge or parallel disc and the valve seats. In theory, when the disc is fully lowered, it should block the fluid passage. However, in practice, solid particles in the fluid (such as sediment, welding slag, or scale) can easily become trapped between the disc and the seat sealing surfaces. Even very small particles can prevent the disc from fully seating, leaving microscopic gaps on the sealing surface and causing leakage. This phenomenon is particularly common in pipelines with unclean fluids.
