Q:Which is the same diameter flange and flange lid?
This depends on the specific specifications, small flange cover more expensive than large diameter flange, flange flange Gabby expensive
Q:Flange NPS4-Class150 SORF 20 ANSI B16.5 this model, what does mean after SORF?
There is no doubt that the pressure is 20# steel kg has been given and whether it is Class150 or American Standard American Standard GB no 20 kg standard will be marked as PN2.5 or PN16 PN1.6 standard flange PN25 like no PN20 or PN2.0.In addition SO with diameter flange sealing surface is a process of RF on behalf of the form
Q:What is the water line flange and what is the difference between it and the ordinary flange?
Water line flange. For the same sealing surface flange, if the sealing surface has water line, the sealing effect is better, applicable pressure higher.Water has no specific criteria, are generally custom processing, mainly divided into three types, one is the spiral, concentric circle and three water line line, close comparison of the helix, concentric helices to some relatively sparse. Conditional permission, 1~3 lane. Usually the structure is: inverted right triangle (cross section form), according to requirements, generally 2mm wide, 1mm deep.The utility model has the function that a labyrinth seal is formed when the flange is connected, and the leakage of gas or liquid is reduced. 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.
Q:What do the Chinese flange F R represent?
The data code that you see is shown on the old standard. F table flange sealing surface is flat R table flange sealing surface is protruding surface. Specific structure, you can Baidu, GB/T9113 can be very clear and clear.New standard flange sealing surface structure codeFull plane (FF)Tongue and groove face (TG)Concave convex surface (MFM)Protrusion (RF)Ring connection surface (RJ)
Q:What is low pressure flange valve?
The pressure is not high, 0.6-4.0MPa, connection way for the flange connection valve, called low pressure flange valve
Q:What do you mean by flange specification 10K?
This is a JIS standard, that is, a Japanese standard. Domestically, it is a ship's standard pressure indication. "10K" means "PN1.0MPA".
Q:The material of the flange is 20#. What does that mean?
20 steel, commonly known as No. 20 steel.
Q:What is flange connecting plate?
What we do in SINOPEC are all cross wiring, do two pieces of welding in the flange at both ends of the pipe wall, and then connected with copper wire.
Q:What are the differences between the clamping and flange styles of valves?
The clamp type is light and self sealing, and the installation is very simple, and the installation and adjustment are easy. More and more pairs of clip valves are used in the middle and low pressure pipelines.
Q:What type of flange does the 159*6 pipe fit with?
Can only tell you is DN150 pressure is how much, you did not say, use the industry also did not say. Do you use continental flanges or American flanges?. So I'm not sure what the exact model is
