Q:I checked a lot of standards and marked a F1, but I couldn't find the corresponding size in the corresponding manual! Good halo

Generally, this size is not fixed, should be depending on the actual use of the occasion, it seems to have an empirical formula to

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:Oil seal flange

Flange sealing surface of the three types: planar sealing surface for the pressure is not high, medium non-toxic occasions; uneven sealing surface, suitable for higher pressure situations; the sealing surface of the tenon, suitable for flammable and explosive, toxic medium and high pressure situations. A gasket is a ring made of a material that produces plastic deformation and has a definite strength. Most from the non metal plate gasket is cut down, or by professional plant size, the material for the asbestos rubber sheet, asbestos board, polyethylene plate; also useful thin metal plate (Bai Tiepi, stainless steel) asbestos nonmetal materials such as wrapping made of metal gasket; and a belt around and asbestos tape made of thin steel and the spiral wound gasket. The ordinary rubber gasket for temperature lower than 120 DEG C; asbestos rubber gasket is suitable for steam temperature lower than 450 DEG C, the oil temperature is below 350 DEG C, the pressure is lower than the 5MPa of the occasion, for general corrosive medium, is the most commonly used acid asbestos board. In high-pressure equipment and piping, copper or aluminum, steel 10, stainless steel lens or other shapes of metal gasket. The contact width of the high pressure gasket and the sealing surface is very narrow (line contact), and the sealing surface and the gasket have higher processing finish. Flange, threaded connection (wire), flange and welding flange. Low pressure small diameter wire connecting flange, high pressure and low pressure big diameter all use welding flange, different pressure flange thickness and connection bolt diameter and quantity are different. According to the different grades of pressure, the flange pad also has different materials, from low pressure asbestos pad, high pressure asbestos pad to metal pad. 1. to classified material of carbon steel, cast steel, alloy steel, stainless steel, copper, plastic, Aluminum Alloy, argon Ge Lek, PPC etc..

Q:How many bolt holes and how big bolts are there in all sizes of 16 kg flanges?

108 different manufacturers produced are different, generally with 16, some with 18, generally each one level of flange 2 (such as 108 16 159 of the 18, and this has been added) flange 108 is 8, 159 or 8 more than 200 which is 8 a 325 is like 16, anyway to bolt him for more more more bolt holes

Q:What role does Sino French play in the waterproof casing pipe?

In the waterproof casing pipe engineering, mainly used for pipeline flange connection. The need to connect the pipe, flange mounted with a low-pressure pipe can use wire connecting flange, the use of more than 4 kilograms of pressure welding flange. Between the two flange and seal, and then fastened by a bolt flange with different pressure.

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:Our factory production of wind tower is to use forged flange (and specification is written in the continuous casting slab is not allowed), incoming raw materials warranty flange is written in continuous delivery, that is not the flange casting forging? Are you in a hurry to accept the goods?! I have less money, thanks in spirit, please knowledgeable people teach in, with little to say, it is best to have some basis for what? Thanks a million!

Casting and forging flange flange is not the same, is the use of steel or steel forged flange through blanking - heating - forging - lathe - - - - type oil packing factory etc.,Casting flange is the use of iron, iron grinding electric furnace melts, the molten iron is poured into a mold, cooling, processing, and some extra processing procedures, is that, molten iron is poured into a mold, molding after heating in forging a processing form.

Q:SolidWorks cannot make a miter flange?

No tangency, tangency, no tangency, sheet metal can not be done

Q:The equipment itself, metal, is the conductor. Why do we have to do the cross connection at the connecting flange? A little more detailedFlange is bolted through, you say that the anti - corrosion treatment, that is, paint what, but why did the anti-corrosion treatment, but it is easy to spark it? The pipeline carries natural gas. For example, say thank you

Inflammable and explosive places 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 jumper.

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
