Steel backing rings

Steel backing rings is an important mechanical part, mainly used to connect two or more pipes, equipment, etc. It is usually a disc with holes, which can be used to accept bolts or other connectors to achieve fixation and connection between different parts. In pipeline engineering, Steel backing rings are often used in conjunction with PVC Stub End because they can ensure the safety and stability of the pipeline system.

Function

The main function of Steel backing rings is to achieve a tight seal through bolt tightening to prevent the leakage of fluids such as gas and liquid. This sealing mechanism relies on the holes on the flange plate. By inserting the bolts, the two flanges are tightly connected, and a gasket is added in the middle to increase the sealing effect.

The operation of Steel backing rings is relatively simple. You only need to tighten or unscrew the screws to complete the connection or disassembly, which is especially important in emergency repairs. The simple operation process not only saves time, but also reduces the difficulty and cost of maintenance.

Advantages

1. Pressure resistance and corrosion resistance: Steel backing rings can withstand high pressure and corrosive environments, which makes it widely used in various industrial environments. Whether it is petroleum, chemical, food processing, or sewage treatment, it can perform well and ensure the stable operation of the system.

2. Excellent sealing performance: The two pipes or equipment are connected by bolts, and a sealing gasket is added in the middle to ensure the tightness of the connection and prevent fluid leakage. This design not only improves safety, but also reduces resource waste and environmental impact.

3. Wide range of use: Due to its durability, easy installation and maintenance, it is widely used in various industrial pipeline systems. Whether it is high temperature, high pressure or low temperature, corrosive media, steel flanges can provide reliable connection solutions.‌

JUNNUO can supply various PVC fittings with SDR11 and SDR17 from DN63mm to DN1200mm include: flange, stub end, equal tee, reducing tee, ball valve, coupling, reducer, end cap, 45 degree elbow, 90 degree elbow, etc.

Brief Detail:

PVC pipe fittings are widely used for water supply, petroleum, gas, chemical industry, water treatment, environmental protection, pharmaceutical and other fields, with the feature as follow:

• Light weight: Each unit weight is only 1/6 of cast iron pipe, so it is very convenient to transport.
• High strength: Could bear 45Mpa at maximum.
• Low resistance: Inner wall of the pipes are smooth, no dirt and no blocking. Could reduce 30% loss than cast iron pipe.
• Corrosion resistance: With good high acid resistance, alkali resistance, chemical resistance and electrochemical resistance, thus, there will be no corrosion in the process of use.
• Easy to installation: Use glue connection and flange connection, which will be convenient to installation and seal reliable.
• Long service life: The maintenance time could up to 50 years under normal working pressure.
• Low cost: Low transportation and installation cost, total project cost will 30-40% less than cast iron pipe.
• Non-toxic and sanitary: PVC fittings confirm to the standards of drinking water, and there is no secondary pollution during water transportation.
