Groove flange

Grooved flanges are usually used in fire and water supply pipes.

The grooved flanged pipeline is a device which is used to convey gas, liquid or liquid with solid particles by connecting pipes, pipe connectors and valves. Usually, after the fluid is pressurized by blowers, compressors, pumps and boilers, it flows from the high-pressure part of the pipeline to the low-pressure part, and can also be conveyed by the pressure or gravity of the fluid itself. Pipelines are widely used in water supply, drainage, heating, gas supply, long-distance transportation of oil and gas, agricultural irrigation, hydraulic engineering and various industrial devices. It is good to prevent gas pollution when used.

Groove flange corrosion resistance:

1. use media such as water, alcohol, ammonia, barium carbonate and benzene (the temperature of WCB material is -29 -425 C).

2. Use medium such as particle, oil, pulp, carbon dioxide gas (stainless steel material can use temperature - 60 ~232 ~C).

3. It is strictly forbidden to use ionic liquids containing fluorine (such as HF etc.) and not to use strong alkali and phosphoric acid (temperature less than 150 C, concentration more than 30%).

4. The general working temperature of stainless steel is less than 150, and the pressure range is 0.6-2.5 MPA. It should be noted when ordering. It can be easily switched between mode and bypass mode through panel operation and good microcomputer technology. It can effectively improve the power factor, filter the transient surge in the circuit and roll the flange.

1) the installation position, height, import and export direction meet the design requirements, and the connection should be firm and tight.

2) all kinds of manual valves installed on insulated pipes must not be lowered.

3) Check the appearance of the valve before installation. For the valve whose working pressure is more than 1.0 MPa and the valve which plays the role of cutting off on the main pipe, the strength and tightness performance test should be carried out before installation, and the valve can be used after qualified. In the strength test, the test pressure is 1.5 times the nominal pressure, and the duration is not less than 5 minutes. The valve shell and packing should be qualified without leakage.
