Q:What is blind through flange?
For the blind flange end of the pipeline, to shut off the pipeline
Q:I am learning machinery, there is a book in the book, LAN type,
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 padFlange connection is easy to use and able to bear greater pressureIn the industrial pipeline, using flange connection is very extensive. Within the family, the small diameter of the pipe and low pressure, see flange connection. If a boiler room or a production site, everywhere is the flange connection of pipes and equipment.
Q:Steel pipe can flange connection, aluminum pipe can flange connection?
The steel pipe, the aluminum tube and the copper pipe can be flanged connected.Flange connection is the two pipes, fittings or equipment, each first fixed on a flange plate, and between the two flange with flange pad, finally by bolt two flange of a detachable joint tension so closely together.purposeThis connection is mainly used for cast iron pipe, lining hose, non ferrous metal pipe and flange valve, etc., the process equipment and flange connection is also using flange connection.The main feature of flange connection is convenient disassembly, high strength and good sealing performance. When installing flanges, the two flanges shall be kept parallel and the sealing surfaces of flanges shall not be damaged and shall be cleaned.
Q:The soul of darkness, how about the souls on the slopes beside the cursed frogs outside 3 flanges?
4. magic, bow and arrow can only serve as an auxiliary, can not serve as the main force. 5. opening gifts suggest choosing a flame metamorphic gem, the early game (Wangcheng, outer walls and undead streets), 80%-90%'s enemies, weak fire. 6. sword God and God was badly cut chicken. Case: a main broadcast take the sword in the tomb of the dungeon play skeletons, a multi segment, the first under a huge damage, directly to the skull behind the play apart, waving empty, only the skeleton together again. Look at the real egg pain, case two: the 2 generation, giant sword and big chicken legs, when the enemy moves, you can directly put the enemy lying prone. But in this seat, the little monster in the move when the giant sword shot, often against the chop. I suspect that the 3 generation has "hard and direct protection", which is a continuous attack on the same target, and the target will be continuously reduced, which is a bad news for the weapon. Think of the 3 generation of giant weapons compared to the 2 generation, moves and withdrawal are slow. 7. most BOSS do not have "routines" for opportunistic. For example, the 2 generation, many non DLC original BOSS, can be raised to shield the back of the stream, "Lai die", there are several UP with this habit against the three generation of BOSS and small soldier, the result of crazy suffering. Even the ordinary Knight mobs are in your shield around him, he will use a Shield Slam your shield, causing damage prevention, and anti kill!!! BOSS war, against the 2 generation of giant BOSS has a formula called "crotch person", the "best student change, otherwise it will crazy. More than 8. UP anchors said in an interview that the 3 generation of "anti - roll decisions" is the most difficult of all generations
