Dimensions of the connection flanges for magnetic flap level gauges
Thread Content
I would like to ask the experts: the standard process connection flange size for magnetic flap level gauges is DN25. Under what conditions is it necessary to use a larger flange?
Is it necessary to increase the fluorine lining of the measurement tube?
It can be selected if there are special requirements, but these should be specified at the time of ordering.
Apart from DN25, what other common specifications are there? Thank you
DN20 DN25 DN32 DN40
The commonly used magnetic flap process connection flanges are mostly DN20 and DN25； As long as the fluidity of the medium is not an issue, flanges of larger sizes don’t make much difference.
The connecting flange is a loop flange, which is generally determined based on the size of the pre-existing opening in the equipment. Since the measuring tube we use is generally 50, the connecting tube is 25.
Equipment made of fiberglass reinforced plastic, PP, or with linings is preferably larger in size; it is difficult to manufacture when the pipe openings of the equipment are too small
It depends on how you design it on-site; the standard sizes are 25, 32, 50, and 80. The size chosen is always determined based on the client’s requirements on-site, so it doesn’t really make a difference
