The applicable media of flanges are oil and gas, automobile and ship machinery manufacturing, aerospace, metallurgy chemical, transportation, electric power, central heating, vacuum, refrigeration, oil, gas, water, acid etc.

Flange head features:
1. Save time and effort: when breaking and connecting oil roads through quick joints, the movement is simple and saves time and manpower.
2. Fuel economy: when the oil circuit is broken, the single valve in the quick connector can seal the oil way and the oil will not flow out, so as to avoid the loss of oil and oil pressure.
3. Environmental protection: when quick joints break and connect, oil will not leak and protect the environment.
4. The equipment design is unique and convenient to transport: large equipment or hydraulic tools that need to be portable, which can be transported after disassembling and disassembling using quick joints, which can be assembled and used after arriving at the destination.
Economy: all these advantages create economic value for customers.
Precautions for flange use:
1. Please do not apply to fluids other than fluid.
2. Do not exceed the maximum use pressure limit when using.
3. Do not use outside temperature range to prevent wear or leak of sealing materials.
4. Do not make artificial blows, bend, stretch, prevent damage.
5. Do not use the metal powder or dust and other places to prevent the damage or leakage.
6. The installation of screw thread should not exceed the maximum tightening torque during installation to prevent damage.
7. Do not use a cracked hose to prevent leakage or loss.
8. If the machine is used for vibration and impact, the durability will be reduced.
9. The flow must be a clean fluid filtered by the filter.
10. Do not remove quick joints.
Flange Yin side commonly known as: quick joint locking arm, pull fantasy fast connection, the suspension loop type fast connection, fast connection types - A, B, C, D, E, F, DC and DP can be any combination according to the equipment, size is 1/2-6 "can also be based on customer requirements have different size. Materials are brass, stainless steel, aluminum alloy, pp etc.

Flanges have the following characteristics:
1. Simple structure, easy operation, quick connection and opening.
2. Compact size, light weight, good sealing and interchangeability.
3. It is widely used in various medium, such as liquid and powder.
4. The joint is connected with taper pipe thread, taper pipe external thread, intubation connection, flange connection and so on.

Flanged side use method:
Model B, C, D, DC can be assembled into A set of quick joint products with model A, E, F, DP, and vice versa. Users can use their own specific use to select products. When connecting with thread, the threaded part should be added to the seal. When connecting with the hose, tighten the hoop to ensure the sealing of the connection. Fast connector is mainly divided into 304 (CF8) 316 (CF8M) material fast connector, quick connector, light quick joint, light quick connector. Any combination of stainless steel quick joints can be arbitrarily assembled into one end of thread and one end of the thread; Both ends are taken over; One end of the thread, one end of the thread; Or any blockage.
