Q:What is blind through flange?
For the blind flange end of the pipeline, to shut off the pipeline
Q:How to calculate the flange quote formula?
Well, I come with you to analyze the existing problems of the calculation formula, this formula is not actually a few written, there are certain to me now to analysis:The first formula is as long as the steel industry in the people to see that, this algorithm is certainly a problem, the problem in 0.616, 10 mm per metre weighs 0.616 kg, and (diameter * outer diameter - diameter - * * * aperture aperture hole number) * actual volume = flange thickness. The latter 0.00001 CM is the calculation of the results into g. such a calculation method, I temporarily ignore how he results, first of all, there is a theoretical error, ask the volume of *0.616= weight?The theory cost and actual operation cost cost, the general foreign trade company own calculated price bargain with us, so the price is called the theory of price, and we are holding the actual cost of operation between manufacturers, often makes us uncomfortable is the theory cost and actual cost gap.Let's analyze some of the most widely used formulas for calculating flange weight on the web:(outer diameter * outer diameter * inner diameter * bore bore diameter * hole diameter * hole number * thickness *0.616*0.0001 unit cmExternal diameter * outer diameter * inner diameter * bore bore diameter * bore bore * thickness *7.93*0.0001 unit cmOutside diameter * outside diameter *1234*, thickness inner diameter * inner diameter *1234*, thickness *0.00001
Q:What is the welded 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's the thickness tolerance of neck flange?
Technical specification for GB/T15530.8-1995 copper alloy and composite flangesDifferent standards require different tolerances. You can choose what standards you want
Q:What's the difference between a clip flange and a flange?
Flanged butterfly valves are flanged on the valve and bolted to both ends of the valve to connect the flanges to the pipe flanges. Sealing surface wear resistance, long service life. The utility model has the advantages of unique structure, flexible operation, labor saving, convenience, and high and low pressure without the pressure of the medium
Q:Flange DN25 PN4.025 what does it mean? 4, what does it mean?
2, in the valve industry, PN as nominal pressure symbol, and make the value of PN after the value of MPA, PN4.0, its nominal pressure value is 4.0Mpa
Q:I would like to ask you master valve has a pair of clamp and flange connection,
To clip type, general caliber is small, pressure is not big. Flanges are suitable for large bore, and others have been answered
Q:What does the 25*3 of flange material specification (angle steel) mean?
The model does not mean the size of the different edges and sizes of the same model. Therefore, the width, the edge and the thickness of the angle iron should be filled out in the contract and other documents, so as not to be indicated by the model alone. Standard Specification for hot-rolled equal angle iron is 2#-20#.Application: the angle iron can be made up of different force components according to the different structure.
Q:How high is the flange flange?
You need to understand the flange protruding this piece is why, suddenly face RF, itself protruding surface it is used to put a car washer, water bursting on the surface, to seal gasket and better. Flange strength requirement is flange thickness of C, not protruding out of the thickness, too thick, coupled with the gasket, exposing a large gap, easy to rain or water rusty.
Q:Flange gasket RF600-6. What does this 6 mean?
Flange gasket RF600-6 in this representation method, several letters and data are defined as:RF corresponds to the form of the normal half surface, and belongs to the RF face flange600: nominal diameter is 6006 representative: this flange pressure rating is 6Bar
