Q: That is to say, I'm going to collect Apple mint. How can I get in? I've got plenty of laps and I haven't found the entrance: Out of the west gate, walk for a while and then go up. It is recommended to open a small map on the right. You can see the mountain, then walk from the middle of the mountain, and then you can see the flowers on the map

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: What is a flange? Where is it usually used?: Add a gasket between the two flanges and secure with bolts. 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.

Reducer flange for motor and reducer connection, as well as reducer and other equipment between the connection.

Q: What are the application technologies of welding flanges?: 3, the ring should be used in full penetration weld butt weld; 4, the ring should be post weld heat treatment, and 100% X-ray or ultrasonic inspection and radiographic inspection conforms to the II class JB4730 requirements, ultrasonic detection with JB4730 I request. Three. The outer slope of the neck of the butt weld flange shall not be greater than 7O. The welding flange strictly controls the technical parameters during production and welding, and ensures the full function and value of the welding flange in production and use.

Q: What's the meaning of the middle flange? What's the difference between the flange and the flange?: for example, the flange valve flange has three, in the channel on the side flange, in the middle to connect the valve cover for the flange in the middle flange.

Q: DN200 how many screws are there in the weld flange?: DN200 welding flange has 8 and 12 screw holes two kinds.According to JB/T81-59 standard:MPa0.6 below, the outer diameter 315mm plate thickness 22mm Phi 18 hole, 8 hole center Phi 280MPa1,0., the outer diameter 335mm plate thickness 24mm Phi 23 hole, 8 hole center Phi 295MPa1.6, the outer diameter 335mm plate thickness 30mm Phi 23 hole, 12 hole center Phi 295

Q: Magic Baby, where is the entrance to the North Garden of flange city?: This way, even if it's the garden entrance. Go in, just this way.Walk to 494.73 and turn south, and you'll see a bunch of different flowers.

Q: Why use special flange for butterfly valve?: The flange type butterfly valve is provided with a flange on the valve, and a bolt is used to connect the flanges at the ends of the valve to the pipe flange.Tianjin Tanggu valve limited liability company founded in 1956, formerly known as Tianjin Tanggu valve factory, the successful restructuring in 2004, the registered capital of 28 million 90 thousand yuan, is a professional manufacturing enterprise design and development, production, installation, sales and service as one of the. Leading products are: Central butterfly valve, flange butterfly valve, metal butterfly valve, gate valve, check valve, hydraulic control valve, micro resistance, slow closing check valve, multi-function water pump control valve and other products. At the same time, the production of different materials, pressure, specifications, driving mode of the control valve, pressure reducing valve and other products, there are more than 50 series, more than 1200 varieties. Annual production capacity of more than 8000 tons. Products covering all parts of the country, and exported to Europe and the United States and other countries, widely used in water supply and drainage, electricity, petrochemical, metallurgy and other industries.

Q: Shandong 03 fixed ventilation pipe flange production, installation, how to take charge?: The first chapter of the corresponding item to support.- fixed number: 9-546~749The eleventh chapter plastic ventilation pipe and components production and installationFour, the wind pipe production and installation projects include pipe fittings, flanges, reinforcement box, but does not include hanging support bracket, hanging support bracket, using the first chapter of the stent project.- fixed number: 9-590 interface and flexible expansion joint flange9-589 flexible interface and expansion joint without flange (pay attention to the difference between two quotas)The twelfth chapter of glass steel ventilation ducts and parts installationThree, glass steel ventilation pipe installation project, including three links, elbow, tube, pipe fittings and Tianyuandifang installation flange reinforced frame and the hanging bracket installation, not including the cross wind landing bracket. The landing bracket shall be calculated in accordance with the first chapter of the support project.- according to the above description, flange manufacture and installation has been included in the amount of wind control stability.
