- Q: How many bolt holes and how big bolts are there in all sizes of 16 kg flanges?
- You said this decision can be empty and bolt by bolt much, because the flange 16 kilograms he represents not only much, such as to the decision of the 59 flange bolts and how much air is generally 59 bolts, flange 4 bolt space using 14 bolts, 59. All 4 bolts empty more than 59 is still some 4 empty, there is 8 according to the size of the flange bolt empty it is not the same, and the use of bolts are based on flange to determine the size of the bolt can also use a smaller, bolt general equipment use 4.8 hardness the special equipment used is 8.8 bolt hardness, 16 pound flange generally use 4.8 hardness
- Q: Flange PL40 (B)What does PL40 mean in flange PL40 (B) -1.6RF304HG20593-97?
- HG20592-97 is the Ministry of chemical industry standard "welding flange plate steel pipe flanges" (European system), PL refers to the type of flange welding plate flange, (B) refers to the application of the pipe diameter B series (Metric), flange diameter DN40 nominal diameter is 46mm, with a 45mm diameter steel pipe.
- Q: What does "-150# SO/FF" mean by flange 4?
- This is a American Standard flange, corresponding to the standard ANSI B16.5, pressure 150LBS, varieties of SO (SLIP-ON, namely hubbed flange), FF refers to the sealing surface of the flange, from RF, RTJ and so on, size is 4 ", also called DN100.. Thank you.
- Q: What is the maximum pressure of the flanges RF and RTJ?
- RF is generally maximum 15.0MPa, RTJ maximum 42.0MPa.The concave convex flange is usually used in the German standard GB and PN4.0, PN6.4MPa level, is mainly decided by the pressure rating, concave convex flange sealing convex flange ordinary (RF) better, but not easy to replace the gasket.
- 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: How many kinds of flanges are there?
- 4. according to the material for making flangesAccording to the flange material can be divided into: cast iron flange, steel flange, plastic flange, copper flange and so on.At the same time, there are 4 standards for flanges in our country, namely, versatility and specificity. Each flange standard is not limited to the scope of this trade, but it is crossed and permeated. In order to gradually unify the flange standard, the National Machinery Committee has formulated a series of flange standard, where GB/T9112~9124 - 2000 "steel pipe flange" series standard is quite comprehensive, but this does not mean the national standard to replace the other flange standard. HG/T20592~20635 - 2009 "steel pipe flanges, gaskets and fasteners" is adjusted and revised based on the original HG/T20592~20635 - 1997, which is set by European and American system system respectively in the preparation of pipe flange standard system, clear and operational use.
- 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!
- Forged flanges and cast flanges use different levels of stress, and forged flanges can be used in high and low pressure pipelines,Casting flanges can only be used for non pressure lines, otherwise leakage is very easy.Hebei bend flange, my name is Liu Jiangong.Flange production using continuous casting does not mean that the flange is casting, can only say that raw materials are not up to standard. Let's pay for the goods. High pressure pipe, as far as possible the use of round steel material.
- Q: CF, ICF, is the flange the same?
- The ICF flange (ConFlat Flange) has a raised sharp edge inside it. It is made of all metal sealing parts by squeezing the copper gasket to deform it to achieve the purpose of sealing vacuum. Widely used in ultra high vacuum field equipment.
- Q: What are metric tubes and British tubes? What's the difference between them? How do you choose flanges?
- It's just a different unit. English is expressed in inches of steel pipe size metric is in meters that steel tube: Imperial size in inches, is an international pipe size series, commonly known as "big diameter series" metric tube: the unit is mm, is a series of pipe size is widely used for decades of domestic chemical industry and other industrial sectors the Department, commonly known as "small diameter series" inch thick wall series uses the pipe schedule number Sch.XX; while the wall thickness metric tube from 2mm, interval 0.5mm, 10mm interval is 1mm. The difference between metric and inch tube tube is the largest pipe diameter is not the same. Like DN50, metric tube diameter is 57, 60.1 inch diameter flange type connection structure: the pipe flanges and pipe is divided into the following six basic types: flat welding, butt welding, socket welding, loose screw flange and integral flange. The seal type flange sealing surface of a table, the entire plane, convex concave convex surface, groove, ring groove five.
- Q: How to set the bending coefficient of SolidWorks sheet metal base flange?
- Sheet metal bending and extension, the material side will be elongated, one side is compressed, the factors affected are: material type, material thickness, materials, heat treatment and processing of the situation and bending angle. PROE will automatically calculate the length of the material being stretched or compressed during the bending and extension of the sheet metal.
