Q: How do you calculate the size of the flange? How many inches do you calculate? What's the inside diameter or what?: It's 3 inches.A 1 inch, 3 inch is equal to 25.4mm, 80mmTwo, flange diameter of 190 diameter 80 in diameter diameter corresponding to 80 mark, is 3 inches.Turn left and turn right |

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: What's the flange surface?: Flange sealing surface has a full plane FF, protruding surface RF, convex M, concave F, tenon surface T, groove surface G, ring connection surface RJ, general concave convex MF, mortise and tenon surface TG, ring connection surface RJ are paired usePL welding plate flange with flange, SO diameter, WN butt welding neck flange;

Q: What is the welding flange valve, is it the flange and pipe welding, and then the valve flange with bolts on the pipe connected to the flange? What is the threaded flange valve?: A welded flange valve is a valve installed on a pipe to weld flanges.Welding: welding, also known as the melt, is a kind of heating, high temperature or high pressure way of metal or other thermoplastic materials such as plastic manufacturing process and technology. To achieve the purpose of joining by welding in the following three ways:1. Heating the workpiece to be melted locally to form a molten bath. The bath is cooled and then joined. If necessary, the melt can be added to the melt;

Q: What is the flange? What are its application areas and principles?: 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.Flanges are widely used in construction, power generation, machinery and many other fields, and their main functions are as follows:1. Connect the pipe and keep the sealing performance of the pipeline.2, to facilitate the replacement of a section of the pipeline.3, easy to disassemble check the pipeline.4, to facilitate the closure of a section of the pipeline.Classification of flanges1. carbon steel, cast steel, alloy steel, stainless steel, copper and aluminum alloy are classified by material2., the production method can be divided into forging flange, casting flange, welding flange and so on.3. makes the standard can be divided into national standard (Ministry of chemical industry standard, standard oil, electricity standard), American Standard (ASTM), German standard (DIN), Japanese standard (JB).

Q: WN, SO, BL, TH, LJ and SW are the abbreviations of what words are. How do you translate Chinese? Class 150 is the stress level. Does that mean the pressure is 150 Bar? Thanks: The 1 floor is written in English, but the translation is not professionalThese abbreviations refer mainly to the welding structures of flanges, necks and tubes or nozzlesWN [neck welding flange]Is [SO] hubbed flangeBL is [flange], also known as "blind plate.""

Q: What is the SO flange?: Hubbed flange. The other can query HG20592-2009, there are inside.

Q: What are the specifications of orifice flanges? Be comprehensive: Appendix A of national standard HG 20592-2009 is marked with only WN (high neck welding flange)Pressure rating PN10~PN160Beside the flow hole socket welding or NPT mouth NPS 15 bearingASME B16.36-2009 American Standard marked WN (high neck flange) and SO (neck flange) twoPressure level 300LB~2500LB no 150LBBeside the flow hole for the 1/2 "NPT age

Q: What's the difference between a clip flange and a flange?: This problem, mainly refers to the butterfly valve in two forms, pairs of clamp and flange type:The clip butterfly valve (valve itself without flange) is a double headed bolt to connect the valve between the two pipe flanges. The clip butterfly valve is simple, small and light in weight and consists of only a few components. The utility model can be rapidly opened and closed only by rotating 90 DEG, the operation is simple, and the valve has good fluid control characteristics.

Q: What's the price? Melphalan is a product of GlaxoSmithKline PLC in the uk.: Hongkong side reputation is better, that is, Mong Kok that Hongkong new special pharmacy can buy, GlaxoSmithKline produced 25 tablets, about 1000 Hong Kong dollars
