- Q: Where is the difference between the double flange limit expansion joint and the double flange transmission joint?
- From the model:Double flange limit expansion joint is VSSJA-2, referred to as B2F; double flange transmission joint is VSSJAF, referred to as C2FFunctionally:Double flange limited telescopic joint is mainly used in the allowable displacement range absorb axial displacement and axial pressure pipeline thrust, loose connection is especially suitable for the pipeline vibration or have a certain inclination and turning in. It can prevent the pipeline due to excessive displacement caused leakage and damage compensation joint.
- Q: For flange who is more detailed explanation? For example, how to position?
- The question is a bit difficult to answer. I use some commonly used criteria to explain it.The ASME B 16.5 -2009 defines the construction criteria for pipe flanges and flanged fittings, including the definition of the flange pressure grade, the temperature and pressure curve of the flange material, etc., and is a very detailed construction code. According to the two part of the flange, a flange sealing surface in the form, such as the process of the convex surface surface groove face ring joint face; two flange form, such as welding welding socket welding etc.!The definitions in EN ASME are similar to those in 1092-01-2007!. The difference is that the ASME defines a pressure rating of CLASS series EN, defined as the PN series, and differs in the size of the flange sealing surface and the flange form.HG/T 20592-2009, the latest 2009 edition of the Ministry of chemical flange standards on the basis of the largest reference to the definition of ASME and EN, but there are still differences. In EN 1092-01-2007, at the same level under different pressure, the thickness of the flange form may not be the same, but in HG/T we can clearly see that all the size of the flange flange form is used in EN integral flange thickness. Personal feeling of the Ministry of chemical engineering flange standard strict and logical, and EN and ASME still have a gap.
- Q: Flange PL40 (B)What does PL40 mean in flange PL40 (B) -1.6RF304HG20593-97?
- RF refers to the sealing surface of the flange for the projection type; 1.6 is nominal pressure 1.6MPa; 304 is the flange material. The latest standard is HG/T 20592-2009, steel pipe flanges, gaskets and solid parts, instead of HG20592~20635-1997.
- Q: 60 seamless steel tubes with 50 flanges, right?
- On the next floor, the DN50 seamless pipe has an outer diameter of 60.3 and a flange with DN50. Of course, corresponding to their thickness of SCH? The same thing.
- Q: Is it a flange or a Flange?
- 3, according to the mechanical (JB) industry standard: integral flange, welded flange, welding plate flange, butt welding ring loose plate flange, welding ring loose plate flange, flange ring loose plate flange, flange cover.4, according to the national standard (GB): integral flange, threaded flange, flange, butt welding and hubbed flange hubbed socket welding flange, butt welding neck flanges, ring plate flange, butt welding ring loose plate flange, welding ring loose plate flange, flange ring loose plate flange, flange cover.
- Q: there is a pair of flange drawings, the above mark is 6-M12 evenly distributed 23 drill 24, what is the specific meaning?
- The 23 attack drill 24 means with drill out the light hole cylindrical surface depth of 24mm, and then use the screw thread tapping into the effective depth of 23mm, which uses standard gauge M12 can be screwed into the 23mm, however, it should be marked drawings of consultations, the final hole should have 1.5 to 2 times the pitch pitch (M12 is 1.75), is about 3mm of the margin, or even the best teacher is also very difficult to achieve. This is my old fashioned experience for reference.
- Q: what is the difference between this, and when what form of connection ah?
- The clamp is used for small caliber, and the flange is basically big bore and big pressure.
- Q: One side is flat plate and side hubbed flange can be connected to it
- The same standards, the same pressure, the same caliber, with these three points can be connected
- Q: The soul of darkness, how about the souls on the slopes beside the cursed frogs outside 3 flanges?
- Extinguish the flames of the 3 towers; open the doors; there is a way to go there
- Q: Now in chemical, flange pn2.
- It does not include the fluctuation pressure of the fluidDesign pressure refers to the maximum instantaneous pressure acting on the inner wall of a pipe system. Generally, the pressure of the work force and the sum of the residual water hammer pressure are usedNominal pressure is to design, manufacture and convenient use, a nominal pressure set artificially. The nominal pressure is the actual pressure unit, "pressure" is commonly known as the Chinese, unit is "Pa" instead of "N".
