Grooved Coupling Pipe Fitting

As a major manufacturer of piping solutions, YINUO offers a wide selection of grooved coupling pipe fittings. For over 30 years the company has designed and built malleable steel, ductile iron and mechanical joining systems for the industry.

In 2010 YINUO entered grooved fitting production to meet evolving customer needs. All grooved couplings comply with standards such as EN10242, ANSI, ASME and DIN, ensuring dimensional accuracy and maximum operating pressures up to PN25 and 25 bar.

Along with grooved products, YINUO’s expansive catalog covers valves, flanges, gaskets and other ancillary items. This enables turnkey pipelines to be designed, manufactured and installed with the highest quality components.

Quality is assured through rigorous production protocols and certifications from leading certifying bodies including UL, FM, CE and BSI.



Product Description

Grooved pipe fittings are a type of mechanical pipe joining system commonly used in industrial piping applications. Rather than welding or threading pipes together, grooved fittings connect pipe via interlocking steel grooves cut circumferentially into the pipe ends.

A flexible coupling houses rubber gaskets that compress to form a pressure-tight seal between the grooves. These couplings can be installed without heat and are suitable for joining different pipe materials like steel, ductile iron.

Compared to other joining methods, grooved fittings offer several advantages. They can be installed faster without specialized skills or equipment like welders. The grooved connection is very secure and will not leak or come loose over time. Disassembly and replacement of sections is also simpler if needed.

Product For Grooved Fittings Ductile Iron Flexible Coupling:

Ductile iron flexible couplings are versatile pipe fittings designed to connect and join two pipes together while accommodating slight misalignments and vibrations. These couplings are constructed from ductile iron, a material known for its high strength, durability, and resistance to corrosion.

One of the key benefits of ductile iron flexible couplings is their ability to compensate for axial, angular, and radial pipe movements. They can absorb vibrations, shocks, and expansion/contraction of the pipes, reducing stress on the system and preventing damage. This flexibility allows for easier installation and maintenance, as it can accommodate slight changes in pipe alignment.

These couplings also provide a reliable and leak-tight connection. The internal gasket or sealing element creates a tight seal between the pipes, ensuring no leakage of fluids or gases. This is particularly important in applications where a secure connection is crucial, such as water distribution systems, HVAC systems, and industrial piping.
