The core advantage of PVC cyclone single-layer flat quadruple (solvent welding connection) lies in its unique cyclone structure. This design effectively reduces air retention and hydraulic shock inside the pipeline by guiding the water flow to rotate along a specific path, thereby significantly reducing noise and vibration during drainage and improving the smooth operation of the overall system. The product adopts a single-layer flat structure, which reduces the overall weight while ensuring structural strength, making it easier to transport and install. It is especially suitable for engineering scenarios where space is limited or weight-sensitive.
The specifications of the product are D110×110 mm, and the interface size meets the international general PVC drainage pipe standards and can accurately match PVC pipes of the same specifications. Each package contains 8 units, suitable for mass construction projects, helping to improve on-site installation efficiency and reduce material management costs. All dimensions are precision molded and rigorously tested to ensure that each product meets consistent high standards in terms of dimensional tolerance, wall thickness uniformity and connection adaptability.
This product is made of high-purity polyvinyl chloride (PVC) raw materials, and has chemical resistance, UV aging resistance and long-term thermal stability. The material itself does not contain heavy metal plasticizers, meets environmental protection requirements, and is suitable for construction projects with high standards for water quality and environmental safety. The solvent welding connection method forms chemical fusion at the interface through special PVC glue. After the connection is completed, it is almost integrated with the pipe body. It has extremely high sealing and compressive resistance, and can withstand dynamic water pressure and temperature fluctuations for a long time without leakage.
Its flat cross-shaped structure occupies little space during installation, and is suitable for pipe distribution in wall mezzanines, under floors or in densely equipped areas, especially for vertical drainage riser systems in high-rise buildings. The cyclone guide groove is integrated cast during mold forming, and the runner transition is smooth and there are no dead corners, effectively preventing debris from accumulation and blockage, improving the system's self-cleaning ability.
