Types of Flanged Fittings

The flanged fittings produced by our company mainly include the following types:

DI Flange Fittings
Our DI Flange Fittings ensure secure pipeline connections. They join pipes perfectly. These fittings feature flanged ends. Use them in water systems. Install in industrial plants.

Ductile Iron Double Flange Duckfoot Bend Elbow
This Ductile Iron Double Flange Duckfoot Bend Elbow changes flow direction. It supports vertical to horizontal transitions. The unique design prevents settlement issues.

DI Loosing Flange Fittings
DI Loosing Flange Fittings provide flexible connections. They allow easy pipe alignment. These fittings simplify maintenance work. Use them in tight spaces.

Advantages of Flanged Fittings

Simple to Assemble and Connect

Plumbing professionals can use flanged pipeline fittings to connect to pipelines and other parts more simply. Flanged pipeline fittings connect pipes much better than threaded fittings like adapters.

Simple to Maintain and Flexible

Flanged pipeline fittings are also extremely flexible. They can reach regions that conventional pipeline fittings frequently fail to achieve. For example, flange pipeline fittings are ideal where the elimination of pipelines, adapters, or hose lines is essential.

Strong Assembly

Another advantage of flanged pipeline fittings is that they can tolerate vibrations, shocks, and pressure changes. They are, therefore, less likely to get damaged than conventional hydraulic fittings. Moreover, flanged pipeline fittings are much less likely to make pipelines loose and provide a way to leak out.

Applications of Flanged Fittings

Industrial Piping Systems: Ductile iron flange fittings are extensively used in industrial piping systems, including those in chemical processing, power generation, and manufacturing facilities.

Water and Wastewater Systems: These fittings are employed in water and wastewater treatment plants to connect pipes of different materials and sizes.

HVAC Systems: Ductile iron flange fittings are utilized in heating, ventilation, and air conditioning systems to connect pipes and ducts.

Fire Protection Systems: They are used in fire protection systems to connect pipes and sprinklers.

Marine Applications: Ductile iron flange fittings are suitable for use in marine environments due to their corrosion resistance.

Installation Steps For Flanged Fittings

Preparation
In the preparation step, the preparation happens by gathering the required tools and materials. These tools and materials are mentioned above, such as threading machines, flange, and safety gear. Before starting the process of installing flanges on ductile iron pipes, inspect the entire flange and pipe thoroughly for any debris or defects.

Alignment
Make sure that the flange and the pipe are perfectly aligned. DI pipe flange assembly is a step that needs precise operations. The alignment of components is essential to achieve a reliable connection in the piping system. The alignment and orientation of the flange need to be taken care of carefully.

Insertion
Insertion of the flange is a crucial step. After the threading process is done, the flange must be carefully screwed onto these threads at the end of the pipe. This insertion is done using the wrench or the spanner that was provided in the preparation step. The flange should be tightened correctly, but it must not be over-tightened.

Bolt Tightening
A primary step in installing flanges on ductile iron pipes is inserting and tightening the bolts. Bolts should be inserted through the holes that are on the flanges and the part they are getting installed to. A wrench or spanner must be used to tighten these bolts in the pipe flange bolting procedures.

Gasket Placement
This step is taken when the flanges require a gasket. If the gasket installation on DI pipes is essential, the gasket is placed between the flange and the part it is getting connected to. Make sure the position of the gasket is correct when installing it. The main reason a gasket is used is to enhance a leak-proof seal.

Final Checkup
As the final checkup, a thorough inspection must be applied. Any signs of potential issues such as misalignments or leaks have to be determined. A pressure test can be of great help if necessary. By following these safety and security inspections, a reliable piping system is ensured.

FAQ

Q: What materials are flanged fittings made from?

A: Flanged fittings are commonly made from ductile iron, carbon steel, stainless steel, or cast iron. The material of flanged fittings is selected based on pressure, temperature, and fluid type to ensure long service life and safe operation.

Q: What sizes do flanged fittings support?

A: Flanged fittings are available in a wide size range, usually from DN50 to DN2000. Different sizes of flanged fittings allow use in small pipelines and large municipal or industrial projects.

Q: What gaskets are used with flanged fittings?

A: Flanged fittings usually use rubber gaskets such as EPDM or NBR. The gasket creates a tight seal between flanged fittings and pipes, preventing leakage under pressure.

Q: Can flanged fittings be reused?

A: Yes, flanged fittings can be reused if the fitting and flange face are in good condition. Replacing the gasket allows flanged fittings to be reinstalled safely in many cases.

Q: Are flanged fittings suitable for high pressure?

A: Flanged fittings are suitable for medium to high pressure systems when the correct pressure class is selected. Proper bolt torque and gasket choice help flanged fittings perform safely.

Q: Can flanged fittings be customized?

A: Yes, flanged fittings can be customized by size, pressure class, coating, drilling standard, and logo marking. Custom flanged fittings help match specific project needs.
