Grooved pipe fittings, as crucial components of modern pipeline connections, can be broadly categorized into flexible coupling joints and rigid coupling joints based on their structural characteristics, playing a key role in fire protection, water supply, and drainage systems.
Rigid coupling joints provide a fixed connection for pipelines, preventing relative displacement and ensuring the stability and alignment accuracy of the pipeline system. They securely lock the pipe in place using rigid clamps and are suitable for pipe sections requiring strict alignment and fixed support.
The GB5135 standard clearly defines the performance, testing methods, and usage requirements for grooved pipe fittings, ensuring the reliability and safety of products in fire protection systems. The appropriate selection of flexible or rigid joints requires comprehensive consideration of the pipeline system’s operating pressure, temperature variations, vibration environment, and installation requirements.
DINSEN, as a professional supplier of grooved pipe fittings, offers a full range of high-quality products compliant with the GB5135 standard. DINSEN flexible grooved fittings feature a special rubber sealing ring and reinforced clamp design, ensuring long-term sealing reliability while allowing for moderate pipe displacement. Meanwhile, DINSEN rigid grooved fittings, with their high-strength groove design and precision manufacturing process, provide a robust connection for piping systems.
Proper selection and application of grooved fittings not only improves the safety and reliability of piping systems but also significantly reduces installation and maintenance costs. DINSEN products are widely used in fire protection, water supply and drainage, and industrial piping, creating value for customers through superior quality and technical service.
