Q:DN125 valve with DN125 flange, right?
Need sealing flange with sealant, you can try SL5051, high temperature resistance, oil resistance is very good
Q:What's the single weld flange? What's the material for the welding flange? What's the difference between the two?
Flanges are made of full plastic flanges and metal flanges, and flanged fittings are also required. There are also injection molding, butt welding, spray molding, forged flanges and injection molded butt joint cast iron flanges, corresponding to injection molded butt flanges. There is no difference between single welding flanges and welded flanges. They are achieved by welding technology
Q:The difference between flange and flange B
What is the difference between a flange and B flange?:1, a V type groove, B U groove, so B easier penetration, so its strength and stiffness is higher; B flange with a short barrel, therefore is a rigid flange, can be used for high pressure, large diameter.2, welded flange and direct vessel welding, the weld size is smaller or the solution without groove welding, can not guarantee the flange and the container also force strength calculation reference looper flange. Welded flange should not use strict occasions in the inflammable and explosive and extremely harmful medium height, etc., can not be used in severe cyclic condition; B flange generally accompanied by a thick short barrel, short cylinder flange and welding quality, and also can ensure the flange container stress intensity the calculation can be considered as an integral flange. B flange is widely used in medium and low pressure vessels and piping connections.3 steel pressure container, a flange for nominal pressure 0.25-1.6Mpa, operating temperature is higher than -20-300 DEG C; steel pressure vessel flange type applies to nominal pressure 0.25-4.0Mpa, operating temperature is higher than -20-350 DEG C.Flanges, flanges, flanges, or flanges. 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.
Q:What do you mean by "RF", "A" or "B" in the flange?
That is to say, the size of the outer diameter of the pipe
Q:How can the flange be packed? Wooden cases often export flanges and require packing. But I don't know how to calculate the packing
The flange is container, by weight is good, the flange is heavy. Usually 23 tons, one cabinet is fine. You can use regular wooden flange specifications. General 2 tons more than a wooden pallet, more than 10 pallets is a small cabinet, fully prepared to have eleven, two, a serious loss of Party losing one ton.
Q:What flange is the change-over flange?
A device that converts a form of connection (or a specification or size) into another form of connection. If the main form of this device is a flange, it can be called a change-over flange. Accordingly, there is a changeover joint and a switch socket.Connect:First, each is fixed on a flange plate, and between the two flanges, and the flange pad, the bolts are fastened together, and the connection is completed. Some pipe fittings and equipment have their own flange, but also belong to flange connection. Flange connection is an important connection way for pipeline construction. Flange connection, easy to use, able to withstand greater pressure. Flange flanges are widely used in industrial piping. In the home, the pipe diameter is small, and it is low pressure and can not see the flange connection. In a boiler room or production site, flanges are connected to pipes and equipment.
Q:Socket welding flange 900-NPS0.5 what do you mean?
900 indicates the pressure grade, and NPS0.5 indicates your flange size. Equal to our DN15 flange. 0.5 inches.
Q:What is flat flange?
Flat flange: a connecting part between a pipe and a pipe, attached to the end of the pipe. The flange is lined with bolts to secure the two flanges.Brief introduction:Production standardGB: GB/T9112-2000 (GB9113, 1-2000 ~ GB9123, 4-2000);Ministry of chemical industry standards: HG5010-52 ~ HG5028-58, HGJ44-91 ~ HGJ65-91, HG20592-97 series, HG20615-97 series;Mechanical department standard: JB81-59 ~ JB86-59, JB/T79-94 ~ JB/T86-94, JB/T74-1994;Pressure vessel standard: JB1157-82 ~ JB1160-82, JB4700-2000 ~ JB4707-2000, B16.47A/B, B16.39, B16.
Q:Can the hole on the flange be threaded?
Sure, bring.Some flanges for special use require threaded thread on some flange holes due to installation and disassembly (such as top wire holes).Of course, flanges in most places are threaded.
Q:The difference between the flange and the flange root
It is a problem of internal and external diameter. DN20 is the nominal diameter, and the 25 is corresponding to the outer diameter of the tube.In practice, we should pay attention to some of which is an inner diameter, and corresponds to the two pipes. The pipes corresponding to DN20 are of 25 and 27 specifications. While DN32 corresponds to 38 and 42, DN50 corresponds to 57 and 60, DN100 corresponds to 108 and 114, DN125 corresponds to 133 and 140, and DN150 corresponds to 159 and 165.Therefore, in the flange production, sales, procurement, we must pay attention to carelessness, but to let themselves suffer.
Our company has strong professional technical force, rich experience, integrated data and advanced equipment, as well as high-quality forging, machine-processing, assembling and packing production lines. Our product quality is in full compliance with both national and international standards, and we have obtained the ISO9001-2000 quality certification. Warmly welcome all to come to visit, investigate and negotiate business.
