Carbon Steel Galvanized Flange

Carbon steel galvanized flange, galvanized, nickel plated, butt welded flange is a type of pipe fitting that refers to a flange with a neck and a circular pipe transition, and is welded to the pipe. There are many types and models of butt welded flanges, and butt welded steel flanges are used for butt welding of flanges and pipes. They are mainly used in welding technology and have good usage characteristics and performance. Their structure is reasonable, and their strength and stiffness are relatively high. It needs to be determined based on specific circumstances to ensure the specific value and performance of the welded flange, and to withstand high temperature and high pressure. Welding flanges have a wide range of applications, and their usage range is determined according to different characteristics. They are mostly used in situations where the medium conditions are relatively mild, such as low-pressure unpurified compressed air and low-pressure circulating water. The advantage is their cost-effectiveness. Suitable for steel pipe connections with a nominal pressure not exceeding 2.5MPa, the sealing surface of the welded flange can be made into three types: smooth, concave convex, and mortise and tenon groove. Smooth butt welding flanges are widely used, and the other two types of butt welding flanges are also quite common in use. The production level and technical requirements of butt welded flanges shall comply with the corresponding requirements of JB4726-4728.

Produce and process according to certain standards to ensure that the products produced and processed meet the quality standards. Welding flanges have different production standards in use and production. Producing and using according to the corresponding standards can ensure the practical value and function of welding flanges. The production and implementation standards for butt welded flanges include ANSI, BS, DIN, GB,ISO,JIS,JPI, ASME,UNI,AS...,The range of applications for butt welded flanges includes industries such as boiler pressure vessels, petroleum, chemical, shipbuilding, metallurgy, machinery, and food. Welding flanges are used at building valves in transmission and distribution pipelines that have undergone cathodic protection, as well as in buried pipeline valve wells that require potential partitioning (zone) isolation. The pressure rating, material, and standards of butt welded flanges have different characteristics and features. When used according to certain principles, methods, and techniques, they can be produced and processed according to corresponding standards to ensure good value and function in use.
