Q:What is flange?
Flange is the abbreviation of flange, usually refers to a similar plate shaped parts of the plate around the opening of several fixed holes used to connect other parts. Flanges are used in pairs. Is widely used in machinery, so it is all sorts of strange things, as long as the call or call the flange flange.The flange is the most common in the pipeline project, in pipeline engineering, mainly used for pipeline flange connection.
Q:The function of steam turbine cylinder flange and bolt heating device
The cylinder of the high temperature steam turbine should bear high pressure and temperature, and the tightness of the joint surface of the cylinder must be ensured. Therefore, the flange of the cylinder must be made wide and thick.In this way, the starting of the turbine will bring about a certain difficulty, that is, a larger temperature difference along the width of the flange. If the temperature difference is too large, the thermal stress will cause the cylinder to deform or produce cracks. Generally speaking, the cylinder is easier to heat than the flange, and the heat of the bolt is transmitted to it through the flange, so the bolt is heated more slowly.For the double cylinder unit, outer cylinder heating cylinder is much slower than the outer cylinder, the flange is more slowly, because the flange temperature rises slowly, hampered the cylinder thermal expansion between the rotor and the cylinder caused by excessive expansion, so that the turbine flow gap, friction.
Q:What are the standard use of flanged mirrors?
Flanged mirrors are equipment mirrors, styles such as illustrations:The equipment vision is in accordance with the time of publicationJB593-64HGJ501-86 mirror standard mapHG/T 21619-1986 mirror standard mapIn addition to the mirror is associated with the flange neck Mirror Standard (JB595-64, HGJ502-86, HG/T, 21620-1986) with light mirror (HG/T 21575-94)
Q:Mechanical flange problems, there is a pair of flange drawings, the above mark is 6-M12 evenly distributed 23 drill 24, what is the specific meaning?
The 23 attack drill 24 means with drill out the light hole cylindrical surface depth of 24mm, and then use the screw thread tapping into the effective depth of 23mm, which uses standard gauge M12 can be screwed into the 23mm, however, it should be marked drawings of consultations, the final hole should have 1.5 to 2 times the pitch pitch (M12 is 1.75), is about 3mm of the margin, or even the best teacher is also very difficult to achieve. This is my old fashioned experience for reference.
Q:What is the flange of the stamping parts? What is the specific surface of the flange mentioned in the stamping die?
The flange is a transliteration of the word "Flange", that is, the flange. In the production of drawing dies, the blank is not fully drawn into the die. This is the flange. In simple terms, the edges of a vertical wall can be called flanges. There are flange connections in machine parts, such as the connection of rural water pump and steel pipe.
Q:Why is there only one gasket between the two flanges?
A shim is placed between the two flanges to increase the seal.
Q:What kind of material is the flange of A105?
Very common American Standard material: ASTM A105 forgings
Q:What are the factors associated with the leakage of gaskets for pipe flanges and how to improve the sealing performance of gaskets?
The flange gasket leakage with you by flange structure, to improve the flange sealing gasket is not light, the main structure and the use of pressure, there is a direct relationship between different pressure flange it received, followed by the corresponding gasket; to understand these technologies please find relevant chemical or manual pipe flange gasket. The chemical standard GB/T20592-2009 has detailed parameters.
Q:What is the equipment flange?
The container flanges on the container, the equipment flanges on the equipment, the pipe flanges on the pipes, and the accessories on the valve lines, called the attached flanges. This is a term used in every industry. The standard book does not have these two terms.Equipment flange refers to the equipment shell, equipment, cylinder or equipment head connected flange. The equipment flange can be made of HG20592~HG20634 steel pipe flange or container flange.JB4701~JB4703 refers to the vessel flange flange, JB/T4721 pipe box flange, flange, flange ring hook container flange generally as equipment flanges.Specially used on the equipment include: take over flange, manhole flange, hand hole flange, loading and unloading hole flange, mirror flange, character blind flange and so on.Steel pipe flange: welded flange, flange, hubbed flange, blind flange, loose flange is commonly used in the pipeline. But also useful on the device. As the flange equipment, general equipment of low pressure, DN less than 400 is used, the cylinder for seamless steel tube.
Q:Is there any difference between the injection flange and the injection joint?
The injection flange you mean is the flange on the die The flange or the barrel? And injection molding? Refers to the nozzle or barrel in the rocket head?
