Application Analysis of Flange in Mechanical Design The flange is a disc-shaped part, the flanges are used in pairs and are most common in pipeline engineering. In plumbing, flanges are primarily used for pipe connections. In the pipelines that need to be connected, a variety of flanges are installed, and the low-pressure pipelines can use wire-bonded flanges, and the welding flanges are used at pressures above 4 kg. Pumps and valves, when connected to the pipeline, part of these equipment, also made into the corresponding flange shape, also known as flange connection. Connection parts that are closed at the same time by bolting on both planes are generally referred to as "flanges". For example, the connection of ventilation ducts may be referred to as "flange parts". However, this connection is only a part of the equipment, such as the connection between the flange and the water pump, it is not good to call the pump "flange parts". Smaller such as valves, etc., can be called "flange parts". In plumbing, flanges are primarily used for pipe connections. In the pipelines that need to be connected, a variety of flanges are installed, and the low-pressure pipelines can use wire-bonded flanges, and the welding flanges are used at pressures above 4 kg. A sealing point is added between the two flanges and then fastened with bolts. Different pressure flanges have different thicknesses and use different bolts. Application and installation of elbows: The elbow is used for the connection at the bend of the pipe, and two pipes of the same nominal diameter are connected to make the pipe turn at an angle. Carbon steel elbows, cast steel elbows, alloy steel elbows, stainless steel elbows, copper elbows, aluminum alloy elbows, etc. The elbow can be said to cover the use of all walks of life across the country, from small families to enterprises, each elbow has its own advantages and uses. The elbow is a type of connecting pipe commonly used in pipe installation for the connection of the pipe bend. Other names: 90 degree elbow, right angle bend, love and bend. Wear-resistant elbows can be favored by the market and continue to replace some traditional anti-wear materials, the fundamental reason is its excellent product quality, as well as in the traditional anti-wear materials. In order to obtain the influence of the upstream elbow installation conditions on the performance of the inner cone flowmeter and the minimum straight pipe length required, the computational fluid dynamics numerical simulation is applied to the inner cone flow of 100 mm diameter and equivalent diameter ratio of 0.45/0.65/0.85. A simulation study of the upstream single 90° elbow was carried out. The simulation medium is normal temperature water, and the Reynolds number range is 0.498×105～4.98×105. The research scheme is divided into two categories: baseline and upstream 90° elbow, a total of 15 groups. Using the relative error of the average outflow coefficient and the additional uncertainty as the main evaluation criteria for the installation conditions, the length of the straight pipe section of the upstream 90° elbow is given and compared with the foreign research conclusions. Stud bolt standard The standard of stud bolts is very important for production and inspection. What are the contents of the stud bolt standard? What are the applications of stud bolts? The world pump valve network introduces you to the standard of stud bolts. The stud bolts are manufactured according to the GB897-901 standard. The materials used are: Q235, 45#, 40Cr, 35CrMoA, Q345D. The specifications are: M3mm-M100mm, the length can be customized according to user needs. High-strength stud bolts, made of 35#, 45#, 35CrMoA, 25Cr2MoV, 304, 316, 304L, 316L, 2H, 2HM, B7, B7M, B16, B8, 8, B8M, 8M, widely used in electric power, chemical industry , refining, valves, railways, bridges, steel structures, automobile and motorcycle parts, etc. Stud bolt function: generally used in mining machinery, bridges, automobiles, motorcycles, boiler steel structures, hanging towers, large-span steel structures and large buildings. Representation of studs: General studs are: M12×100 GB/T901-88 (standard) 35#/35# (material) 8.8/8 (modulation level) means: diameter = 12mm length =100mm GB/T901-88 is the national standard (of course, industry standards can also be used as needed) 1, used in the main body for large equipment, you need to install accessories, such as sight glass, mechanical seal seat, reduction frame, etc., this is the stud bolt used, one end screwed into the main body, after installing the attachment, the other end with a nut Since the attachment is often removed, the thread may be worn or damaged, and it may be convenient to replace it with a stud. 2. For the thickness of the connecting body is very large, when the bolt length is very long, the stud bolt will be used. Stud standard: GB/T900-1988 Stud bolt national standard reference: The end of the GB2 fastener outer spun part; GB196 common thread basic size; GB197 common thread tolerance and fit; GB1167 transition fit thread (screw into cast iron, steel body); GB1180 over-current matching thread (screw into aluminum crucible); GB3098.1 fastener mechanical mechanical stainless steel bolts, screws, studs and nuts; GB3098.6 Mechanical properties of fasteners, stainless steel bolts, screws, studs and nuts; GB3103.1 fastener tolerance bolts, screws and nuts; GB5267 threaded fastener plating; GB5779.1 fastener surface defects bolts, screws and studs are generally required; GB5779.3 fastener surface defects bolts, screws and studs special requirements; GB90 fastener acceptance inspection, marking and packaging; GB1237 fastener marking method.
