Q:What flange is the SOFF flange?
SOFF flange, mean hubbed flange, the whole planePL welding plate flange with flange, SO diameter, WN butt welding neck flange;
Q:Taiwan version Ma flange effect, okay?
Although the British GlaxoSmithKline Group subsidiary of the company's production.
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:What is the welded 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's the difference between cast iron flanges and steel flanges?
The material composition is different, the strength is not the same, mechanical performance is not the same.
Q:Where is the identification shop in flange city (coordinate)?
Mrs. Katie's store 196,78 identifies thingsGlima's home 216,43 appraisers work on the jobStrong brother grocery 191,38 appraisers inaugurationI don't know which one you need
Q:How should we get to know the flange?
For example, such as a long distance transport pipeline, it is necessary to lower the pipes into the pipeline in the pipeline, but install valve, mirror, telescopic device and so on, which can be used in welding welded it up, but after the maintenance is not split off is not? Therefore, most of the pipeline will choose flange joint, so as to facilitate future maintenance and replacement.The flanges are soldered to one end or joined together in other ways, and the two opposite flanges are secured with fasteners (bolts), which form a complete conduit. Pipes and valves, mirrors and so on are basically connected in this way.
Q:What's the meaning of the middle flange? What's the difference between the flange and the flange?
Fran: it's an exotic language. English Name: flange, flange is to make the two cavities connected to the protruding parts or components.
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:Flange "WN100 (B) -16RF S=6" and "SO50 (B) -16RF", "PL200 (B) -16RF" represent what kind of flange,
Two, PL200 (B) -16RFPL is the welding plate flange, 200 is the nominal diameter of 200mm (B) is the use of metric tube (also known as GB tube), 16 is the nominal pressure is 16MPa, RF is a prominent surface seal seal type.Specific flange parameters are not clear, this is HG20592-20635 "steel pipe flange" standard flange.
