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:What's the flange surface?
IF integral flange, SW socket welding flange, TH threaded flange; loose flange ring PJ/SE welding, PJ/RJ welding ring flanges; flanges BL, BL (S) lining flange
Q:What's the thickness tolerance of neck flange?
Specification for JB/T74-1994 pipe flangesSH3406-1996 steel pipe flanges for petrochemical industrySpecification for GB/T17241.7-1998 cast iron pipe flanges
Q:Hole is a through hole on the flange surface?
Flanges in the narrow senseFlange (Flange), also called flange or flange plate. The flange is the part that connects the pipe to the pipe and is connected to the end of the pipe.
Q:The connection between the air outlet and the air duct can straddle the flange
The reason is: according to JGJ141-2004 "ventilation pipe construction technical regulations" requirements, different specifications of the wind pipe have the corresponding stiffness requirements, otherwise, must be reinforced. The tuyere destroys the integrity of the flange, which affects the stiffness of the duct.
Q:What are the specifications of orifice flanges? Be comprehensive
There is no standard flange hole is 6, in order to install the need, mainly to avoid directional (plus or minus 90 degrees, plus or minus 180 degrees), flange holes are 4 multiples
Q:Steel pipe can flange connection, aluminum pipe can flange connection?
Both flanges can be connected. The flange is the joint of the pipe and the pipe.Different media, the choice of flange material is different.You say plastic pipes can also come through flanges. Flanges are usually made of nonmetallic material.Teflon can also be done. The wear resistance of PTFE is chenchen.
Q:Flange valve Q41F-16C/P/R mark, specific meaning?
This is standard regulation, according to "JB/T 308 - 2004 valve type programming method" regulation:Q= ball valve4= connection type: flange1= structure: floating ball direct flow channelF= sealing surface material: fluoroplastic-16= nominal pressure: 1.6MPaC= body material: carbon steelP= body material: chrome nickel stainless steel, such as: 304R= body material: chromium, nickel, molybdenum stainless steel, such as: 316
Q:Does the six angle flange bolt and the six angle bolt have the same meaning?
Different. The head of the flange bolts is like a hat.
Q:About the difference between valve flanges RTJ, RF
Two, flange (Flange), also known as flange, flange plate or edge. A flange is a part that is connected between the pipe and the pipe, used for the connection between the ends of the pipe. It is also used for the flange on the entrance and exit of the equipment. It is used for the connection between the two devices, such as the reducer flange. Flange connection or flange joint means that the flange, the shim and the bolt are mutually connected as a group of three detachable sealing structures. Pipe flanges are flanges used for piping in pipe installations. They are used on equipment and refer to the entrance and exit flanges of the equipment. The flange is lined with bolts to secure the two flanges. Gaskets for gaskets between flanges. Sub threaded flange connection (threaded connection), flange welding flange and flange clamp. Flanges are used in pairs. Low pressure pipes can be made of wire flanges and welded flanges with pressures of more than four kilograms. Add a gasket between the two flanges and secure with bolts.
