  • What connection methods are there for ductile iron pipes？

  • What is the principle of a control valve?

    The core function of a control valve is to precisely regulate process parameters such as fluid flow rate, pressure, level, or temperature within a pipeline. It achieves this by altering the size of the internal flow passage cross-sectional area. Imagine a water faucet on a pipe: opening it wider increases the water flow, while closing it reduces the flow. A control valve operates similarly, but its control is far more precise and is typically operated remotely by an automated system.

  • What is PVC-M pipe?

    PVC-M pipe, fully termed Modified Polyvinyl Chloride Pipe for Impact Resistance, represents an advanced evolution of traditional PVC-U (unplasticized polyvinyl chloride) piping. Its core breakthrough lies in polymer toughening technology, which introduces elastomer particles (such as chlorinated polyethylene CPE or acrylic copolymer ACR) into the PVC matrix to form a "sea-island" composite structure. This modification enhances impact strength by 3-5 times and increases elongation at break by over 50% compared to PVC-U, fundamentally addressing the inherent brittleness and susceptibility to sudden fracture in conventional PVC-U pipes.

  • The role of valves in urban water supply

    Valves play a very important role in urban water supply systems. Generally speaking, valves are used to control the direction, speed and pressure of water flow to ensure that water can flow smoothly to various areas and buildings in the city. Valves can also be used to close or open pipes, maintain and repair water pipes, adjust water pressure, and respond to emergencies (such as leaks or pipe ruptures).

  • The working principle of gate valves and how to select gate valves

    Gate valves use a vertically moving gate to control flow. Their core strengths are near-zero pressure drop when fully open and bidirectional capability, making them ideal isolation valves for complete shutoff with minimal flow restriction. However, they operate slowly, cannot regulate flow, are bulky, and must never be partially open to avoid damage.Selection depends on media properties, pressure, temperature, size, space, operation (manual/automated), and cost to determine type (wedge/parallel, rising/non-rising stem) and material.

  • What is GT Type Ductile Iron Pipe?

    The sealing principle of the GT type interface of GT type ductile iron pipe is similar to that of the T type interface. As the internal pressure of the pipeline increases, the tighter the contact surface between the rubber ring sealing sleeve and the socket, the better the sealing effect.
