BHGHStainless steel socket welding Flange

Q: A metal pipe nominal diameter 1200, using flange connection. In the original installation technical requirement, "parallelism: tolerance is 1mm/1000mm". How do you measure parallelism? What does this "1mm/1000mm" mean? How do you explain that?Another: flange roughness and how to measure and explain??: Parallel degree should be marked that flange mounting flange gap when the maximum and minimum width difference, the difference is not too large, is on the corner of the bolt flange sealing, not partial, or in some places more pressure gasket, gasket in some places may be there virtual pressure, although it does not leak, long time might be have a problem,As for flatness, the surface finish of machined surface should be considered as the flange sealing surface can not be a flat surface, and must be opened with mortise or groove

Q: Is AS2129 TABLE D only flat flange? What are the criteria for TABLE D? The more detailed, the better.: AS 2129-2000, Flanges, for, pipes, valves, and, fittings.You download it and see it, and American Standard Astm B16,9 standard JIS B2220-2004 European standard EN 1092-1-2005 set is basically the same, butt welding, welding, blind plate has more flat out. Just without thread and socket flange.

Q: What is a stone flange?: Anti leakage: stitching seamless, smooth and smooth interface. Easy renewal: any serious damage such as burn marks, stains and cutting marks can also be restored by grinding procedures, so that the surface is as smooth as new. Yi Qingjie: solid, surface, wood, pores, dirt can be cleaned with soap, water or detergent. Sturdy and durable: professional quality guarantee, high temperature and shock resistance, high temperature resistance, the more polishing the brighter. Colorful: a variety of colors for you to choose, and your living space in harmony and unity. Widely used: kitchen and toilet countertops, sinks, window sills, handrails and so on. Penetration of Italy traditional craft adhering to the popular European life concept of flame retardant waterproof and easy to clean everywhere highlight the noble temperament natural charm fusion hundred years process Art beats nature. century products distributed everywhere more health non-toxic antibacterial natural wind random bending does not change the characteristics of the ultimate quality demanding perfect stable color fresh everywhere condensed professional exquisite decoration trend has always been leading the Home Furnishing reflect their personality out of the ordinary resilient material rich colors everywhere individuality style (two) Living Colors - color feeling stylish and colorful stone flange to make your kitchen and bathroom wall Peng Hui students, permeated with elegant and soft.

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?: 2 、 heating the solder with lower melting point independently, without melting the workpiece itself, and connecting the workpiece with the capillary action of the solder (such as soldering and brazing);3, in the equivalent or lower than the melting point of the workpiece temperature, with high pressure, folding, extrusion or vibration, so that the two pieces of mutual penetration between joints (such as forging welding, solid-state welding).According to the specific welding process, welding can be divided into welding, resistance welding, arc welding, induction welding and laser welding and other special welding.

Q: Which flange is the front pipe case flange and the cylinder flange?: A cylinder flange is a flange that is connected with a shell on the shell side, and no flange is used on the ordinary heat exchanger.

Q: I checked a lot of standards and marked a F1, but I couldn't find the corresponding size in the corresponding manual! Good halo: You need to understand the flange protruding this piece is why, suddenly face RF, itself protruding surface it is used to put a car washer, water bursting on the surface, to seal gasket and better. Flange strength requirement is flange thickness of C, not protruding out of the thickness, too thick, coupled with the gasket, exposing a large gap, easy to rain or water rusty.

Q: In the heat exchanger calculation, the actual bolt section area of the cylinder flange is smaller than the required cross-sectional area. What's the matter?: Bolt strength shortage, improvement method:1, check the matching of bolts and gaskets... Do not use low strength bolts with metal gaskets or gaskets.. Unreasonable。

Q: What is the output flange? What's the function?: Low pressure small diameter wire connecting flange, high pressure and low pressure big diameter all use welding flange, different pressure flange thickness and connection bolt diameter and quantity are different.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 pad.

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.

Q: Who knows, the difference between plate flange and hubbed flange in the application.: Hubbed flange is imported from abroad, used for gas valves, gas pipelines etc.. Because of a short neck, flange stiffness can be improved and bearing capacity improved.
