Q:What does "welding flange" mean, and what does fillet welding mean?
A flange is a part used to connect two kinds of pipe fittings. Fillet welding is used to weld the right angle or the right angle of the material. It is said that it is a right angled triangle from the side of the plane after welding. The welded flange is used to connect the flanges with welding. I hope it works for you, huh?
Q:Shandong 03 fixed ventilation pipe flange production, installation, how to take charge?
There are five chapters in the consumption quota of installation engineering in Shandong Province, including 1, 9, 10, 11 and 12 chapters. The corresponding categories are thin steel plate, stainless steel plate, aluminum plate, plastic and glass fiber reinforced plastic. Following, in accordance with the instructions in order, followed by instructions.The first chapter of the production and installation of steel sheet gout pipelineFirst, this chapter includes galvanized steel duct, ordinary steel duct, galvanized steel pipe (no flange connection), fan coil bracket accessories, connecting pipe, ventilation pipe production installation and flexible hose installation, a total of seven 30 items.
Q:Where are metal flanges usually used?
1, less than five screws, there should be cross wiring2: flammable and explosive place is to prevent power leakage and electrostatic spark using conductive metal will better connect the two flange reliable, pipeline grounding, flange generally corrosion caused by poor contact is easy to produce sparks, in order to prevent the accident of flange jumper3, according to:I. code for design of GB50074-2002 oil depots14.2.14 in the dangerous area of the pipeline (oil and gas), the following lightning protection measures shall be taken:1 the flange connections of the oil pipeline shall be bridged and shall not be bridged in a non corrosive environment when not less than 5 bolts are connected2 the metal pipe that is parallel to the ground or the groove of the pipe, when the net distance is less than 100mm, the span of the metal line should be not more than 30m., and the intersection distance of the pipe crossing is less than 100mm, and the intersection shall be connected with metal wire
Q:What role does Sino French play in the waterproof casing pipe?
Such as ventilation pipeline connection, the parts can be called "flange parts." but this is only a partial connection of a device, such as a connecting flange and a water pump, the pump is not called "flange type parts" relatively small. Such as valves, etc., can be called flange parts
Q:Flange PL40 (B)What does PL40 mean in flange PL40 (B) -1.6RF304HG20593-97?
PL 'flat welding flange 40 nominal diameter DN40
Q:What is the meaning of flange PL50-16RF
Flange, nominal diameter 50mm, voltage 1.6MPa, convex seal type.
Q:What is the maximum pressure of the flanges RF and RTJ?
The use of with concave convex surface with tongue and groove face flange is basically the same. Ring groove sealing surface (RTJ) is mainly used in high temperature and high pressure or both high working conditions. In American Standard flange, commonly used in Class 600Lb (part) and 900Lb, 1500Lb, 2500Lb grade pressure. In the German standard and national standard, often used in PNl0.0, PN16.0, PN25.0, PN32.0, PN42.0MPa flanges.
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.
