Duplex Steel 2205/2507 Material Coupling Joint Grooved Pipe Coupling Joint Duplex Steel Coupling Joint

Coupling (COUPLING), a stainless steel pipeline connector, also known as a flexible joint, ferrule, clamp-type union, clamp, grooved joint, stainless steel grooved clamp, stainless steel clamp (Victaulic), groove system. Mainly used in water treatment, municipal water supply systems, high-rise stainless steel water supply, fire protection, air conditioning systems, and other mechanical pipeline connection systems. The joint adopts a flat-end design, utilizing the fit clearance between the joint key shoulder and the pipeline to achieve flexibility. While ensuring strength, the joint does not fully clamp the pipeline, allowing for some axial and radial displacement. The flexible design of the joint can accommodate pipeline deviations without affecting its performance. Suitable for pipelines requiring flexibility. It features fast, simple, reliable, economical, vibration isolation, and space-saving characteristics.

Features

Fast: Can quickly connect pipelines, with installation speed more than 4 times faster than flange connections, and flexibility to prevent leakage due to displacement.

Simple: Grooved pipe couplings are lighter than flanges, with fewer bolts, eliminating complex procedures like hole alignment and locking in flange joints. No special skills are required for operation; workers only need a wrench. Easy alignment during installation, allowing the pipe to rotate freely without deliberate alignment, resulting in fast installation and low labor intensity.

Reliable: Scientifically and rationally designed to provide reliable and durable triple protection for pipelines. The coupling flexible joint uses high-quality rubber ring seals and a high-quality C-shaped structure, ensuring better sealing performance under higher internal pressure.

Economical: Compared to traditional flanges, grooved pipe couplings can save 20%-40% in total construction and cost.

Vibration Isolation: The pipe end can block noise and prevent vibration transmission. The C-shaped rubber ring fully absorbs sound and dampens vibrations. Flexible joints can also address pipeline thermal expansion and contraction, eliminating the need for additional expansion and contraction joints in the entire system.

Space-Saving: The space occupied by grooved pipe couplings compared to flange connections is in a ratio of 2:3. The tightening bolts are non-directional, particularly overcoming inconveniences caused by narrow working spaces.
