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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

Forged flange processing technology: The forging process generally consists of the following procedures, namely, selecting high-quality steel billets, blanking, heating, forming, and cooling after forging. Forging process methods include free forging, die forging, and fetal membrane forging. During production, different forging methods are selected according to the quality of the forgings and the number of […]
