Flat welding flange-related information
Loose flange: loose flange is commonly known as loose flange, welding ring loose flange, flanging loose flange and butt welding loose flange. It is often used in medium (determinant material) temperature and pressure It is not high and the medium is highly corrosive. Today we talk about the types of forged flange sealing surfaces. There […]
There are two main processes for chemically treating the flange surface
There are two main processes for chemically treating the flange surface There are two main processes for chemically treating the surface of flanges: one is high-temperature oxidation, which is often referred to as flanges; the other is blackening at room temperature. With the advent of the era of industrialization, the petrochemical industry, power industry, metal […]
The principle of use of carbon steel flange
Carbon steel flanges are different from flanges that are not produced according to standard sizes, also known as second-standard flanges. Usually, some unscrupulous merchants will reduce the thickness of the flange and the outer diameter to achieve the purpose of saving materials. Steel or leftover steel is used to process flanges. Usually, this kind of […]
Flange connection structure and flange sealing
The flange is an important part of connecting pipes and pipes. It is connected to the pipe end. There are holes in the flange. The two flanges are tightly connected with wear-resistant bolts, and the flanges are sealed with gaskets. There are two connection methods between container parts: non-detachable (welding) and detachable. Due to the […]
Threaded flange forging die according to the implementation of motion
Large thread flange forging dies according to the embodiment of movement can be divided into orbital forging, swing swage forging, roll forging, cross wedge rolling, ring rolling, roll cross rolling and so on. It is fired at high temperature, compact, except for the abrasive deburring process on the inner wall of the tube after which […]
Flange connection form under U-shaped container
Flange connection is usually used in the connection of pipelines, the connection of sealed containers, etc. The function of a flange is to ensure the good sealing of containers or pipelines and prevent the leakage of gas or liquid. Therefore, in general, the sealing structure of a flange connection consists of the flange, Composed of […]
Matters needing attention in the installation process of stainless steel flange
Matters needing attention in the installation process of stainless steel flange 1. In order to prevent intergranular corrosion caused by heating the stainless steel flange cover, the welding current should not be too large. At this time, the current needs to be about 20% smaller than that of the carbon steel electrode, the arc should […]
Flange gasket is the realization of the flange sealing effect
The production efficiency of stamping processing is high, the operation and control are convenient, and it is easy to realize mechanization and automation. This is because stamping relies on molds and stamping equipment to complete the processing. The ordinary press stroke can be multiplied dozens of times per minute, and the high-speed pressure can reach […]
Little knowledge about the flange
The flange is otherwise known as flange or flange. Flanges are parts that are connected to each other between shafts and are used for connection between pipe ends; they are also useful for flanges on equipment inlets and outlets And can be used as a connection between two types of equipment, for example, reducer flanges.
