Welding plate flange for general medium.Hubbed flange suitable for the inflammable and explosive, corrosive, toxic high placesThe sealing surface of flange plate are raised face (RF), hubbed flange sealing surface can be used from surface, convex surface, tongue and groove face.The two structures are different, the sealing effect is not the same, the strength is not the same.
Q:Magic Baby how to enter in the hall in the flange
Limited conditions: morning or evening, level 10 or more, recommend more than 5 teams of 101, first grade to 10 grade, and then to place the former East Garden Xie Fort (47,85) into the call between.

Q:Now in chemical, flange pn2.
Nominal pressure PN (=2.5MPa):Reference value relating to the pressure resistance of piping system componentsWorking pressure is the maximum continuous running pressure acting on the inner wall of a pipe under normal working conditions.
Q:Dn is 250, Pn25 flange, what is the hole distance?
Flange center hole distance d1=370mmFlange diameter D=425Aperture 30Bolt M27
Q:Urgent! Flange tolerance: flatness, parallelism,? Twenty
In a given direction, the degree to which the meter is parallel to the reference surface is within the given tolerance range. 1mm/1000mm represents measurement length of 1000 mm, allowing error of 1 mm.
Q:Flange WN50 (B) -25 RF S=6 specific points
WN indicates that butt welding 50 means nominal diameter DN (B means B series diameter is 57) - 25 is pressure, new standard is 25 kg pressure, old standard is 250 kg pressure RF, sealing surface protrusion S=6 flange diameter thickness is pipe thickness
Q:What is the waterline of flanges?
In addition, if the flange is connected with a non-metallic gasket, it is only possible to process the sealing water line; if the metal gasket is sealed, the water line is not processed.
