seamless black steel pipe

Q:What does the 25*3 of flange material specification (angle steel) mean?: It can also be used as the connecting piece between the components. Widely used in a variety of architectural and engineering structures, such as beams, bridges, towers, hoisting and conveying machinery, ships, industrial furnace, reaction tower, container frame and warehouse

Q:To set the price: The cheapest is more than 100, and the most expensive is five hundred

Q:What is the flange? What are its application areas and principles?: The flange is used for connecting and sealing the head of the container and the cylinder. The container can be disassembled from flange and convenient for maintenance.

Q:What's the DN100 flange?: Reducer flange for motor and reducer connection, as well as reducer and other equipment between the connection.Sort:1, according to the chemical industry standard (HG): integral flange (IF), (Th), threaded flange welding plate flange (PL), neck flange (WN), hubbed flange (SO), socket welding flange, butt welding (SW) ring loose flange (PJ/SE), flat loose flange ring lining flange (PJ/RJ), (BL (S)), flange (BL). 2, according to the petrochemical industry standard (SH): (PT), threaded flange welding flange flange (WN), (SO), socket welding flange (SW), loose flange, flange cover (LJ) (not note). 3, according to the machinery (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:Can the equipment and pipe be directly connected between the pipe and the pipe, flange or welding?: It is better not to connect directly, which will help replace spare parts and later maintenance.

Q:Flange WN50 (B) -25 RF S=6 specific points: WN indicates that butt welding 50 means nominal diameter DN (B means B series diameter is 57) - 25 is pressure, new standard is 25 kg pressure, old standard is 250 kg pressure RF, sealing surface protrusion S=6 flange diameter thickness is pipe thickness

Q:Where is the mansion in the mirror city of magic baby?: Enter here at flange city coordinates 96148;But you need a charm, a red rosary;

Q:May I ask the prawns to help me explain, "coupler" and "flange" mean the same thing, if not, what's the difference between them? Forget everyone, pointing out!!In the first time: For a waveguide type fiber coupler, it is generally a component with Y - type branching, and the optical signal input by one optical fiber can be divided into equal parts. When the opening angle of the coupler branch increases, the leakage of light to the cladding will increase, resulting in excessive loss, so the opening angle is generally within 30 degrees, so the length of the waveguide type fiber coupler can not be too short.

Q:Our factory production of wind tower is to use forged flange (and specification is written in the continuous casting slab is not allowed), incoming raw materials warranty flange is written in continuous delivery, that is not the flange casting forging? Are you in a hurry to accept the goods?! I have less money, thanks in spirit, please knowledgeable people teach in, with little to say, it is best to have some basis for what? Thanks a million!: Now the steel raw materials are mainly ingot and billet, steel materials in the factory are indicated in the warranty on this; and casting or forging flanges and not directly related to see through what kind of flange is processed out of the process if it is casting, casting products. If it is after forging, is forging products, suppliers should be issued by the product warranty, product warranty can be seen by casting or forging. Technical specifications written is not allowed to use continuous casting slab, and if the product for the use of steel raw materials, then even forging products are not qualified, and I hope to help you.

Q:About the difference between valve flanges RTJ, RF: RTJ is metal ring joint sealed, RF is wrapped gasket seal. High pressure use RTJ, low voltage use RF.
