Q:Why is the piece of iron between the two pipe flanges?
This is called a flange gasket, which acts as a seal to prevent liquid from leaking through the flange joint.
Q:What is called a flange hole?
I am engaged in industrial equipment maintenance work, almost every day contact flangeLet's talk about the flange first. The flange is used on the pipe, the fittings and the pipe line. There is a hole in the middle of the disc. It is the same as the diameter of the pipe. There are many screw holes around it. The hole in the middle is the flange hole
Q:With the size of American Standard flange CLASS300 DN15, why the minimum can only find DN20
Minimum DN15. The first one is DN15. 1/2"
Q:Why I can not find the SolidWorks2012 of the body flange buttons?
The sheet metal commands are uniformly arranged in the sheet metal function menu, as on the left of your screenshot,How can I find out?First of all, in your screenshot of green hook, red X above: features, sketches, evaluation and other columns,Right click on the mouse, you can find the sheet metal function menu, tick on it.
Q:What is flange connection pile?
Classification of pilesWith the development of engineering technology, new steel pile and reinforced concrete pile are more and more widely used in engineering construction. Different pile types have different characteristics.Classification according to force condition:Friction piles - most of the load is carried by the friction of the soil around the pile, while the pile at the end of the pile can be neglectedPileEnd bearing friction pile -- the pile whose load is mainly borne by the friction force of the pile bodyEnd bearing piles - most of the load is carried by the supporting force of the pile tip, while the resistance at the side of the pile is negligibleFriction end bearing pile -- the pile whose load is mainly loaded by the end of pileClassification by construction method:Mechanical hole pileBored pileImmersed tube cast-in-place pileReinforced concrete pilePile foundation, precast pile, prestressed concrete pileSteel pileCement soil mixing pileMixing pileOther chemical material mixing pilesAccording to the overall size of the pile classificationLong pilePileShort pileMiddle long stakeVariable cross-section pileAccording to the method of pile driving, prefabricated piles can be divided into driven piles, pressed piles, vibrating sinking piles, rotary piles and so on.
Q:SolidWorks assembly problem (the second holes on the flange can not fit coaxially)
You see a screenshot of the I guess is the hole and flange you shell flange on the hole position is not the same (diameter distribution) please check the threaded hole hole diameter distribution Yuguang pay special attention to the thread size when the reference mark and position! ~
Q:What are the specifications and dimensions of flanges?
Flanges are a disk shaped part, most common in pipe engineering. Flanges are used in pairs.In pipe engineering, flanges are used mainly for pipe connections. In the need to connect the pipe, all kinds of installation of a flange, low pressure pipe can use wire connection flange, more than 4 kilograms pressure use welding flange. Add a gasket between the two flanges and secure with bolts.Different pressure flanges have different thicknesses and use different bolts.Water pump and valve, and in the pipe connection, these equipment parts of the equipment also made corresponding flange shape, also known as flange connection.Usually in the two plane, in the vicinity of the use of bolt connection
Q:What's the specification for flanges with outer diameter 160?
Flanges (Flange) are also called flanges or flanges. The flange is the part that connects the pipe to the pipe and the valve and is connected to the end of the pipe. The flange is lined with bolts to secure the two flanges. Gaskets for gaskets between flanges. Flanges, threaded connections (wire connections), flanges and welded flanges and clamp flanges.
Q:What does flange Class mean 600?
Class 600: marking method American Standard flange pressure, the pressure of 600 pounds, equivalent to 11.0Mpa
Q:Must the flange height go along with the standard?
The flange height is related to the calculation of the flange pressure bearing. The height of the flange will affect the flange strength
