As a pressure vessel, it must have the following characteristics, such as high-temperature resistance, corrosion resistance, leakage prevention, and easy repair. However, the flange interface of a pressure vessel is usually the only channel for handling materials and the interface for connecting to other facilities. The tightness of the butt joint seal of the pressure […]

The formula for calculating the weight of finished carbon steel flanges
When the mold is used, press 500,000 strokes. The neck flange is a part that is connected to each between the shaft and the shaft, and is used for the connection between the pipe ends; it is also useful for the flange on the inlet and outlet of the equipment and is used for the […]
Both high-pressure and low-pressure large diameters use welded neck flanges
The neck flange is divided into a threaded connection (wire connection) neck flange and welded neck flange. The small diameter of the low-pressure has a wire neck flange, and the high-pressure and low-pressure large diameters use the welded neck flange. The thickness of the neck flange with the same pressure and the diameter and number […]
What are the alloy steel flange materials?
Due to the unique impact strength performance of the alloy steel flange, it has been significantly improved compared with other solid-wall pipes. Its ring stiffness is equivalent to that of solid-wall pipes, and its service life is long: the service life of the pipe reaches 50 years under the rated operating temperature and pressure. More […]
There are three types of flange-sealing surface
Pay attention to the stainless steel flange connection. Flange manufacturers generally use bolts on the two planes to connect and close the connecting parts at the same time, such as the connection of ventilation pipes. Such parts can be called “flange parts”. When the water pump and valve are connected to the pipeline, some parts […]
What are the basic process steps of American standard flange-free forging
The American standard or flange is the part that connects the pipe to the pipe to each other and is attached to the pipe end. There are holes in the American standard flange, the bolts make the two flanges tightly connected, and the flanges are sealed with gaskets. American standard flanges can be cast or […]
Technical requirements for butt welding flanges
In the actual production and development of butt welding flanges, different methods and processes are used for production and production. According to the process methods and principles, it has important value and effect on different aspects, and certain elements are added in actual production. Increase the characteristics and value of carbon steel flanges, and express […]
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 […]
