Simple structure: The structure of the welded end flange is relatively simple, and it is easy to install, suitable for various pipeline connections.
The material of the welding end flange can be selected according to the application requirements and working environment. Common materials include carbon steel, stainless steel, and alloy steel.
Carbon steel welding flanges have good corrosion resistance and toughness, and are suitable for low-pressure and low-temperature media such as air, water, and petroleum. Stainless steel welding flanges have good corrosion resistance and high temperature performance, and are suitable for media with high corrosion resistance requirements, such as acids, alkalis, and seawater. Alloy steel welding flanges have high strength and high temperature performance, and are suitable for high-pressure and high-temperature media, such as steam, oil, and gas industries.
In addition, according to different usage requirements, other materials can also be selected, such as nickel steel, WC5 (1.25% chromium 0.5% molybdenum steel), WC9 (2.25% chromium), C5 (5% chromium% molybdenum), C12 (9% chromium 1% molybdenum), CA6NM (4(12% chromium steel), CA15 (4)(12% chromium), CF8M (316 stainless steel), CF8C (347 stainless steel), CF8 (304 stainless steel), CF3 (304L stainless steel), CF3M (316L stainless steel), CN7M (alloy steel), M35-1 (monel), N7M (Hastelloy B), CW6M (Hastelloy C), CY40 (Inconel) and so on.
In general, the choice of welding end flange material depends mainly on the application requirements and working environment.
