Q:What is the difference between the HG/T20615-2009 flange standard and the ASME B16.5 flange standard?
ASME B16.5 has 7 series.HG/T20615-2009 is the 6 series, and Class400 is not included.Rounding up some values.
Q:How many kilograms is WN300-1500M in the flange standard?
The kilogram (symbol Kg) is the basic unit of measurement in the international system of units, and the kilogram is one of the most common basic units used in everyday life. A kilogram is defined as the quality of an international kilogram of raw materials, almost as much as a liter of water. The kilogram is the only one with Si prefixes of the basic unit, and the only one still use manual products for the definition of international units (units with other basic physical properties are defined, in order to replicate in different laboratories).
Q:What do DN and PN stand for on the flange?
The nominal DN identifier;PN identifier for nominal pressure.
Q:The difference between flange and flange B
Steel pressure vessel welded flange suitable for nominal pressure 0.25-1.6Mpa, operating temperature is higher than -20-300 DEG C.Steel pressure vessel flange type applies to nominal pressure 0.25-4.0Mpa, operating temperature is higher than -20-350 degrees.The fillet welds of type B and type A are different in size and different in size
Q:Flange FWN what do you mean?
WN the whole flange means, "F" does not know. Is it the first letter of the word "flange"?.Don't know what to say, I hope you can help. Hello, Zhu Xuechun, Hebei Wan Guan Pipe Industry Co., ltd..
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:What is flange connection pile?
Flange connection pile, as the name suggests, is to use flange to meet the pile. The main reason of the pile connection is that the long pile is needed in the construction, but the length of the pile is limited in actual production, so it must be long enough to meet the requirement, so the method that can be used in the construction is the flange connection pile.Flange pile - - in the upper and lower two piles on the flange plate, flange is processing pile foundation is installed in advance, when the connection is directly good to tighten it
Q:Flanges are welded in the form of PL, SO, WN. What do you mean?
PL welding plate flange,SO with diameter flange,WN butt welding flange;IF integral flange,SW socket welding flange,TH threaded flange;PJ/SE welding ring loose flange,PJ/RJ flat ring loose flange;BL flange cap,BL (S) lined flange cap
Q:What's the flange on the sprocket?
According to the description, spurts phenomenon is actually the roller and sprocket chain lead to alveolar not fully engaged, this 2 points to consider:First, there may be a chain pitch error, may wish to change several chains try. However, the chain is standard, this possibility is relatively small.Two is the sprocket tooth distance error, although sprocket processing is very delicate, but if it is small batch, often line cutting or milling cutter into teeth. Roundness is out of the car, easy to guarantee, the pitch is cut or milling out, it is difficult to say. The diameter of the graduated circle is not so good.
Q:Is the flange a pipe?
Flanges are pipe fittings.Turn left and turn right |Flanges (Flange), also called flanges, flanges, or flanges. A flange is a part that is connected between the pipe and the pipe, used for the connection between the ends of the pipe. It is also used for the flange on the entrance and exit of the equipment. It is used for the connection between the two devices, such as the reducer flange. Flange connection or flange joint means that the flange, the shim and the bolt are mutually connected as a group of three detachable sealing structures. Pipe flanges are flanges used for piping in pipe installations. They are used on equipment and refer to the entrance and exit flanges of the equipment. The flange is lined with bolts to secure the two flanges. Gaskets for gaskets between flanges. Sub threaded flange connection (threaded connection), flange welding flange and flange clamp. Flanges are used in pairs. Low pressure pipes can be made of wire flanges and welded flanges with pressures of more than four kilograms. Add a gasket between the two flanges and secure with bolts. Different pressure flange thickness is different, they use the bolt is also different. Water pump and valve, and in the pipe connection, these equipment parts of the equipment also made corresponding flange shape, also known as flange connection. Any connecting parts that are bolted and closed in the vicinity of the two planes are generally referred to as flanges, such as the connections of the ventilation ducts, which can be called flanges". However, this connection is only part of a device, such as flanges and pumps connected, it is not good to call the water pump flange parts". Relatively small, such as valves, can be called flanges".
