New production process for forged flanges
Free forging has low productivity and a large machining allowance, but the tool is simple and versatile, so it is widely used for forging single-piece and small-batch forgings with simple shapes. Free forging equipment includes air hammers, steam-air hammers, hydraulic presses, etc., which are respectively suitable for the production of a small, medium, and large […]
Flanges should be inspected regularly
A flange connection means that two pipes, fittings, or equipment are first fixed on a flange plate, a gasket is added between the two flange plates, and bolts are used to fasten them together to complete the connection. Some pipe fittings and equipment already have their own flanges, which are also flanged connections. Flanges are […]
What is a flange？
Flange, also known as flange or flange. Usually, it refers to opening several fixed holes on the periphery of a disk-like metal body for connecting other components and is widely used in various mechanical equipment and pipeline connections. Flanges are the interconnected parts between shafts and are used for the connection between pipe ends; they […]
Causes of flange leakage
What is the cause of flange leakage? 1. Reason for flange leakage: wrong mouth The staggered seam means that the pipe and the flange are vertical, but the two flanges are not concentric, and flanges are not concentric, so the surrounding bolts cannot freely penetrate the bolt holes. There is no other way, only reaming […]
The characteristics and sealing principle of flat welding flange
Flat welding flanges refer to flanges that are connected to vessels or pipes by fillet welding. It can be any flange. Check the integral flange or loose flange respectively according to the degree of integrity of the flange ring and straight cylinder section at the time of design. The ring of the flat welding flange […]
Advantages of high-pressure flanges
1. Sealing method: The core of the high-pressure self-tightening flange is a precise, new metal-to-metal seal, that is, the seal is formed by the elastic deformation of the sealing lip (T-arm) of the sealing ring, which is a hard seal; The combination of tendons and bones of the ferrule, the ferrule, and the sealing ring […]
Calculation Method of Flange Installation
The flange is a kind of detachable connection that can maintain a sealing effect within a certain pressure range. The working condition of the flange is composed of a pair of flanges, several bolts, nuts, a gasket and a washer. Under the tensioning action of the bolt, the flange compresses the gasket between the compression […]
Knowledge of butt welding flange
Butt welding flange refers to a flange with a neck and a round pipe transition and connected to the pipe by butt welding, which is a kind of pipe fittings. The advantages of butt welding flanges are anti-corrosion, acid and alkali resistance, long service life, etc., and the price is reasonable, the surface is smooth, […]
