ASTM/API Carbon Seamless/welded Steel Pipe

Q: About the difference between valve flanges RTJ, RF: Different pressure flange thickness is different, they use the bolt is also different. Water pump and valve, and in the pipe connection, these equipment parts of the equipment also made corresponding flange shape, also known as flange connection. Any connecting parts that are bolted and closed in the vicinity of the two planes are generally referred to as flanges, such as the connections of the ventilation ducts, which can be called flanges". However, this connection is only part of a device, such as flanges and pumps connected, it is not good to call the water pump flange parts". Relatively small, such as valves, can be called flanges". Reducer flange for motor and reducer connection, as well as reducer and other equipment between the connection. The flange has a good overall performance, it is widely used in chemical industry, construction, water supply, drainage, oil, light and heavy industry, refrigeration, sanitation, plumbing, fire protection, electric power, aerospace, shipbuilding and other infrastructure projects. Three, RTJ and RF, RTJ and RF, respectively, indicate the form of the flange sealing surface: RTJ means that the metal ring is sealed and used in high pressure situations, such as RTJ, the maximum pressure is 42.0MPa. RF indicates bursting seal, for low pressure applications such as RF, maximum pressure 15.0MPa.

Q: What is the reverse flange?: Positive and negative flanges are a pair of flanges. The reverse flange is another part of the matched flange, so as to avoid the connection between the two flanges of one and the other, because of the different rotation direction. The reverse flange is the standard flange. Standard is flange standard.

Q: Does the six angle flange bolt and the six angle bolt have the same meaning?: Not the same meaning. The six head bolts are hexagonal in shape, and there is a gasket like structure between the head of the flange bolt and the thread!

Q: All details, forms and websites are OK. Thank you: DN15 outside diameter 18, 22 DN20, outer diameter 25, 278 points, did not know has not heard

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

Q: Flanges of different sizes: Variable diameter flange, also known as Reducing Flange, and its inner diameter and the standard flange diameter, there are some differences.In engineering, when the standard flange can not match the fittings and pipes, the reducing flange is used.China's national standards flange standard (GB) and chemical industry standard (HG) two categories, the new chemical industry standard HG/T20592 ~ 206352009 flange is used to the EN as the representative of the European standard pipe flanges (nominal pressure expressed by PN) and the United States as the representative of the American ASME system (nominal pipe flange the pressure expressed by Class), between them the nominal size of the feature size is different; moreover, our country pipeline diameter series is also divided and metric Inch series series, there are differences in the nominal size; in addition, when there are special requirements, such as flange instrument joints, when the glass lined the characteristics of some special requirements (give it a separate "glass lining of different diameter flange" HG/T2140-2009 standard). Therefore, the inevitable mixing in the project, the use of reducing the flange diameter of the method is the simplest and most effective solution, thus the emergence of non-standard variable flange.

Q: What are the application technologies of welding flanges?: Two. The welding flanges are usually made of forging or forging. When made of steel or shaped steel, the following requirements must be met:1, welding flange should be ultrasonic testing, no delamination defects; 2, should be rolled along the direction of steel cutting into strips, bent by welding into a ring, and make steel surface forming ring cylinder. The steel plate directly machined into the butt welding neck flange butt weld shall not;

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: What are metric tubes and British tubes? What's the difference between them? How do you choose flanges?: It's just a different unit. English is expressed in inches of steel pipe size metric is in meters that steel tube: Imperial size in inches, is an international pipe size series, commonly known as "big diameter series" metric tube: the unit is mm, is a series of pipe size is widely used for decades of domestic chemical industry and other industrial sectors the Department, commonly known as "small diameter series" inch thick wall series uses the pipe schedule number Sch.XX; while the wall thickness metric tube from 2mm, interval 0.5mm, 10mm interval is 1mm. The difference between metric and inch tube tube is the largest pipe diameter is not the same. Like DN50, metric tube diameter is 57, 60.1 inch diameter flange type connection structure: the pipe flanges and pipe is divided into the following six basic types: flat welding, butt welding, socket welding, loose screw flange and integral flange. The seal type flange sealing surface of a table, the entire plane, convex concave convex surface, groove, ring groove five.
