seamless black steel pipe

Q: Flange specification PL20 (B): PL slip on plate 20 is DN (B) is a series of B with diameter of 25 steel which belongs to the national standard or Western Europe

Q: you can use PN10 with PN16I mean DN flange is less than or equal to 200, PN10 and PN16, their diameter, thickness, diameter of bolt hole and the bolt is equal to the number of PN16, I read only one more than the PN10 break, can not directly make a groove in the PN10 flange, when PN16. They look exactly the same after the beveling: PN is the pressure grade, PN10 indicates pressure of 10 kg, and PN16 indicates 16 kg of pressure.No, you can use PN16 as PN10 instead of PN10 as PN16You write very clearly,

Q: What is blind through flange?: The through flange is used to connect the two pipe fittings, and the two flanges are connected together by bolts. For the blind flange end of the pipeline, to shut off the pipeline

Q: What's the price of a stack of 600 carbon steel flanges?: Beijing Science and technology for you to answer, flange or flange plate. The flange is the part that connects the pipe to the pipe and is connected to the end of the pipe. It is also used for the flange on the inlet and outlet of the equipment, for the connection between the two devices, such as the reducer flange.

Q: What's the meaning of the middle flange? What's the difference between the flange and the flange?: Generally round, there are other shapes.The middle flange is also the flange, refers to the meaning in the middle,

Q: SolidWorks why can't the side flange be gray?: There are generally two ways to create sheet metal parts. One is to make a sheet metal directly with the matrix flange,

Q: Oil seal flange: Flange sealing surface of the three types: planar sealing surface for the pressure is not high, medium non-toxic occasions; uneven sealing surface, suitable for higher pressure situations; the sealing surface of the tenon, suitable for flammable and explosive, toxic medium and high pressure situations. A gasket is a ring made of a material that produces plastic deformation and has a definite strength. Most from the non metal plate gasket is cut down, or by professional plant size, the material for the asbestos rubber sheet, asbestos board, polyethylene plate; also useful thin metal plate (Bai Tiepi, stainless steel) asbestos nonmetal materials such as wrapping made of metal gasket; and a belt around and asbestos tape made of thin steel and the spiral wound gasket. The ordinary rubber gasket for temperature lower than 120 DEG C; asbestos rubber gasket is suitable for steam temperature lower than 450 DEG C, the oil temperature is below 350 DEG C, the pressure is lower than the 5MPa of the occasion, for general corrosive medium, is the most commonly used acid asbestos board. In high-pressure equipment and piping, copper or aluminum, steel 10, stainless steel lens or other shapes of metal gasket. The contact width of the high pressure gasket and the sealing surface is very narrow (line contact), and the sealing surface and the gasket have higher processing finish. Flange, threaded connection (wire), flange and welding flange. Low pressure small diameter wire connecting flange, high pressure and low pressure big diameter all use welding flange, different pressure flange thickness and connection bolt diameter and quantity are different. According to the different grades of pressure, the flange pad also has different materials, from low pressure asbestos pad, high pressure asbestos pad to metal pad. 1. to classified material of carbon steel, cast steel, alloy steel, stainless steel, copper, plastic, Aluminum Alloy, argon Ge Lek, PPC etc..

Q: Magic Baby, where is the entrance to the North Garden of flange city?: Find the coordinates of the flowers you want, then collect them.

Q: In the heat exchanger calculation, the actual bolt section area of the cylinder flange is smaller than the required cross-sectional area. What's the matter?: Generally choose JB/T4700-2000 "pressure vessel flange" in the flange, you do not need to calculate

Q: The equipment itself, metal, is the conductor. Why do we have to do the cross connection at the connecting flange? A little more detailedFlange is bolted through, you say that the anti - corrosion treatment, that is, paint what, but why did the anti-corrosion treatment, but it is easy to spark it? The pipeline carries natural gas. For example, say thank you: Inflammable and explosive places is to prevent power leakage and electrostatic spark using conductive metal will better connect the two flange reliable, pipeline grounding, flange generally corrosion caused by poor contact is easy to produce sparks, in order to prevent the accident of flange jumper.
