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

Coupling, a stainless steel pipeline connector, also known as a flexible joint, ferrule, clamp-type union, clamp band, grooved joint, stainless steel grooved clamp, stainless steel clamp (Victaulic), or groove system. It is mainly used in mechanical pipeline connection systems such as water treatment, municipal water supply systems, high-rise stainless steel water supply, fire protection, and air conditioning systems. The joint features 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. It is suitable for pipelines requiring flexibility. It offers the characteristics of being fast, simple, reliable, economical, vibration-isolating, and space-saving.

Features

Fast: Enables quick pipeline connection, with an installation speed more than four times faster than flange connections, and provides flexibility to prevent leakage due to displacement.

Simple: Grooved pipe couplings are lighter than flanges, require fewer bolts, and eliminate complex procedures such as hole alignment and locking in flange joints. No special skills are needed for installation; operators only need a wrench. Installation alignment is convenient, as the pipe fittings can be rotated freely without deliberate alignment, resulting in fast installation and low labor intensity.

Reliable: The scientifically and rationally designed structure provides the pipeline with reliable and durable triple protection. The coupling flexible joint uses a high-quality rubber ring for sealing and a high-quality C-shaped structure, ensuring that the greater the internal pressure, the better the sealing performance.

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 the transmission of vibrations, with the C-shaped rubber ring fully utilizing its sound absorption and vibration damping functions. Flexible joints can also address pipeline thermal expansion and contraction, eliminating the need for additional expansion or 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 the inconvenience caused by narrow working spaces.
