Explosion-proof requirements of explosion-proof distribution box

The explosion-proof box is required to be tightly sealed. All the wires in and out of the wire hole are sealed with sleeve rubber sleeves and rubber pads. The inside of the box is not allowed to freely infiltrate the gas. The common box is for air circulation to promote air convection. Explosion-proof distribution box The product components and the general structure to meet the explosion-proof level requirements, the production unit is still through the national explosion-proof safety testing, get the product explosion-proof certification, product process material is more perfect than the ordinary box.

First, the use of explosion-proof distribution box is used for lighting control circuit in a special place, the general switch current is relatively small, the specific number of loops to see how much to control the group of lights, the size of each switch to see how many lights control a group of lights, How large is the current of each lamp.

Second, the application of the environment 1, explosive gas mixture dangerous places: District 1, District 2.

2. Explosive gas mixtures: IIA, IIB, IIC.

3, temperature group: T1 ~ T6.

4, explosion-proof signs: ExdeIIBT6, *ExdeIICT6.

Note: Please specify IIC level.

Third, product characteristics 1. Explosion-proof distribution box shell using ZL102 aluminum die-casting or steel plate welding, the surface of high-pressure electrostatic spray, with stainless steel exposed fasteners, product appearance.

2. Explosion-proof lighting distribution box is well-designed, safe and easy to use, our company provides free one year warranty 3. Box drawings can be provided by your company, or by my company on behalf of the production.

4. Explosion-proof lighting distribution box adopts compound type, module structure, each circuit can be assembled freely according to needs, the general switch box adopts explosion-proof structure, bus box and outlet box adopt increased safety structure.

5. Built-in components can be installed according to the user's requirements high circuit breaker or molded case circuit breaker. Such as DZ47, C65, CM1 and so on.

6. Can be tailor-made according to customer requirements, such as the installation of surge protectors, ammeters, voltmeters, etc., can be equipped with padlock metal handle.

7 applies to lighting and power lines, with disconnection, overload, voltage loss protection and short-circuit automatic cut-off function can be steel or cable wiring.

Meet the GB3836-2000, IEC60079 standard requirements.

Fourth, technical parameters 1. Implementation of standards: GB3836.1, GB3836.2, GB3836.3, GB12476.1, IEC60079

2. Explosion-proof mark: ExdeIIBT6, DIPA20TA, T6

3. Rated voltage: AC220V

4. The main circuit rated current: 20A ~ 250A

5. Branch number: 2, 4, 6, 8, 10, 12

6. Branch current rating: 1A, 3A, 5A, 10A, 15A, 20A, 25A, 32A, 40A, 50A, 60A

7. Protection class: IP54 (IIB), IP55 (DIP), IP65 (with rain cover)

8. Corrosion protection level: WF1

9. Entrance Specifications: G1/2~G3"

11. Inlet direction: Down, Down, Up, Up, Up, Up or Up

Sameless pipe

 Seamless pipe as the name suggests is a pipe without a seam or a weld-joint in contrast to Seam or Welded pipe. In a Seam or Welded pipe, the seam or the weld-joint is the weaker part of the pipe limiting the strength of the pipe to the strength of the weld-joint. Whereas the seamless pipe does not have any such joint and thus has uniform structure & strength all over the pipe body. 

Some commonly used models are

Api5L Seamless Pipe ,A53 Gr.B Seamless Pipe,Astm A106 Gr.B Seamless and so on.

Advantage

The seamless pipe can withstand higher pressure, higher temperature, higher mechanical stress & corrosive atmosphere and find wide applications in Oil & Gas.

Applications

Applications in petrochemical, chemical, chemical, chemical fertilizers, electric power, automobiles, bearings, machinery and structures.
