Flexible Flange Adaptor(For DI Pipe Only)

A flexible flange adaptor for DI pipe is a specialized pipe fitting used to connect ductile iron (DI) pipes to other components in a piping system. Here is an introduction to it:

Structure

Body: Usually made of high-quality ductile iron, which provides strength and durability to withstand high pressure and heavy loads in the pipeline. It may have an FBE (fusion bonded epoxy) coating or epoxy painting on the surface to enhance corrosion resistance.

Gasket: Made of materials like NBR or EPDM, which is placed between the flange surfaces. It provides a flexible and watertight seal, preventing leakage and absorbing vibrations and shocks.

Bolts and Nuts: Commonly made of carbon steel with galvanized zinc plating G4.8/G8.8, or stainless steel such as SS304/SS316. They are used to connect and fasten the flanges of the adaptor and the DI pipe.

Features

Flexibility: Can accommodate axial, lateral, and angular deflections of the DI pipes, compensating for thermal expansion and contraction, settlement, and vibration in the pipeline system.

Easy Installation: The design is relatively simple. It only requires a few simple tools to slide the adaptor over the end of the DI pipe and then tighten the flange bolts to complete the connection.

Sealing Performance: The rubber gasket forms an effective seal, ensuring that the fluid in the DI pipe does not leak out and maintaining the integrity of the pipeline system.

Corrosion Resistance: The ductile iron body with anti-corrosion coating and the corrosion-resistant gasket material enable the adaptor to have good corrosion resistance in different working environments.

Applications

Water Supply and Drainage Systems: In municipal water supply pipelines and drainage networks, it is used to connect DI pipes to pumps, valves, water meters, and other equipment to ensure reliable water transmission and drainage.

Irrigation Systems: In agricultural and landscaping irrigation projects, it connects DI pipes to sprinklers, drip irrigation devices, and other components, adapting to different installation requirements and terrain changes.

Industrial Piping Systems: In chemical, petroleum, and other industrial fields, it is used to connect DI pipes in process pipelines, facilitating equipment maintenance and pipeline expansion.
