Q:Can you have a more general idea?

Is the distance from the lens mount flange from to the photosensitive element between the interchangeable lens camera. In the design at the beginning of the fixed bayonet flange from each lens, for later design can be achieved after installation to bayonet infinity focus.

Q:How should we get to know the flange?

For example, such as a long distance transport pipeline, it is necessary to lower the pipes into the pipeline in the pipeline, but install valve, mirror, telescopic device and so on, which can be used in welding welded it up, but after the maintenance is not split off is not? Therefore, most of the pipeline will choose flange joint, so as to facilitate future maintenance and replacement.The flanges are soldered to one end or joined together in other ways, and the two opposite flanges are secured with fasteners (bolts), which form a complete conduit. Pipes and valves, mirrors and so on are basically connected in this way.

Q:There are 32; 3, 11/2, and so on, please master pointing, by the way, such tagging is based on what standards.

6 inches, 1 right, 4 inches, 3 inches, 2 inches, 1, 2 inches of right.

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:Our factory production of wind tower is to use forged flange (and specification is written in the continuous casting slab is not allowed), incoming raw materials warranty flange is written in continuous delivery, that is not the flange casting forging? Are you in a hurry to accept the goods?! I have less money, thanks in spirit, please knowledgeable people teach in, with little to say, it is best to have some basis for what? Thanks a million!

Forged flanges and cast flanges use different levels of stress, and forged flanges can be used in high and low pressure pipelines,Casting flanges can only be used for non pressure lines, otherwise leakage is very easy.Hebei bend flange, my name is Liu Jiangong.Flange production using continuous casting does not mean that the flange is casting, can only say that raw materials are not up to standard. Let's pay for the goods. High pressure pipe, as far as possible the use of round steel material.

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

American Standard, pressure rating of 150, hubbed flangeSealing surface plane of flange

Q:there is a pair of flange drawings, the above mark is 6-M12 evenly distributed 23 drill 24, what is the specific meaning?

Matching flange, tapping a face is threaded M23, and its matching flange is bolt free access, that is, the smooth surface, must be 24 diameter. Otherwise, it can't be tightened.

Q:Flange DN25 PN4.025 what does it mean? 4, what does it mean?

1, DN25, DN as the nominal diameter of the sign, note that 25mm refers to the approximate diameter reference size;
