Q:Where are metal flanges usually used?

1, less than five screws, there should be cross wiring2: flammable and explosive place is to prevent power leakage and electrostatic spark using conductive metal will better connect the two flange reliable, pipeline grounding, flange generally corrosion caused by poor contact is easy to produce sparks, in order to prevent the accident of flange jumper3, according to:I. code for design of GB50074-2002 oil depots14.2.14 in the dangerous area of the pipeline (oil and gas), the following lightning protection measures shall be taken:1 the flange connections of the oil pipeline shall be bridged and shall not be bridged in a non corrosive environment when not less than 5 bolts are connected2 the metal pipe that is parallel to the ground or the groove of the pipe, when the net distance is less than 100mm, the span of the metal line should be not more than 30m., and the intersection distance of the pipe crossing is less than 100mm, and the intersection shall be connected with metal wire

Q:PROE flat sheet metal design whole wall and the flange wall what is the difference?

but if not a lot of this piece of sheet metal bending, and the shape is not Affirmative square, with it is necessary to cut the flange murals one or several features.

Q:Taiwan version Ma flange effect, okay?

For Asians is certainly some version of the Taiwan version of bede. The Chinese version of Taiwan is called wake. However, it is difficult to buy this medicine at home.

Q:May I ask the prawns to help me explain, "coupler" and "flange" mean the same thing, if not, what's the difference between them? Forget everyone, pointing out!!In the first time

For a waveguide type fiber coupler, it is generally a component with Y - type branching, and the optical signal input by one optical fiber can be divided into equal parts. When the opening angle of the coupler branch increases, the leakage of light to the cladding will increase, resulting in excessive loss, so the opening angle is generally within 30 degrees, so the length of the waveguide type fiber coupler can not be too short.

Q:All details, forms and websites are OK. Thank you

DN15 outside diameter 18, 22 DN20, outer diameter 25, 278 points, did not know has not heard

Q:What does "-150# SO/FF" mean by flange 4?

Four inches, the pressure rating is 150, so is hubbed flange, FF for the whole plane sealing surface

Q:What are the common materials and grades of aluminum alloy flanges?

Melting point 660 DEG C. Boiling point 2327 DEG C. Aluminum is the third largest in the earth's crust, second only to oxygen and silicon, and is the most abundant metal element in the earth's crust. The development of the three important industries, aviation, architecture and automobile, requires that the material characteristics have the unique properties of aluminum and its alloys, which will greatly benefit the production and application of the new metal aluminum. Applications are very extensive.
