Q: What's the flange cover BL20-100FM?: Nominal diameter 20 nominal pressure 100 kg (10MPa) concave flange cover, if in accordance with the HG20601 standard, the size of the external diameter of 130, the center of the hole Phi 90, bolt hole 4- Phi 18, thickness 20, sealing surface concave.

Q: The back of a valve is sealed directly with a flange. What do they want to secure? I saw something called a double disk D219x6. What's this? If I were 150, how big would the pipe be?: After the valve flange sealing plate is normally called flange blind plate, as they are sealed in the middle of things, generally have metal winding pad or Teflon pad. D219x6 (outside diameter * wall thickness) is the specification of the pipe. As to how big the 150 pipe is, this is the standard piece. When you go to the hardware store or the manufacturer to buy it, it is OK to tell him that it is DN150's flange.

Q: What is the difference between the HG/T20615-2009 flange standard and the ASME B16.5 flange standard?: The size of HG/T20615-2009 and the ASME basic B16.5 agreement, is China standard in American Standard standard, and ASME is also the basic material.
