Carbon steel flanges is a grade that is embedded with higher carbon content and other constituting alloys. Carbon steel pipe flanges are a versatile pipe grade that is designed in the shape of a lip or ridge that helps in providing strength and stability to different piping equipment. The CS flanges are utilized in connecting piping grades of different specifications. These flange can be threaded and welded with gaskets used to bolt them.
Carbon steel forged flanges are produced as metal is processed at extreme pressures giving them enhanced tensile and fatigue strength. These flange have an even surface finish with good surface porosity. Our company is a carbon steel flanges manufacturers in India that follows vigorous testing procedures to produce the best products in the industry.
The Low temperature carbon steel flanges are designed to work in cryogenic temperatures without cracking under extreme cold. These flange may be formed in raised, flat, and rtj specifications. A carbon steel raised face flange has a raised surface that is above its bolting area enabling it to securely seal the component. These CS flange can be sealed with soft, semi-metallic, and flat gaskets.
The Carbon steel RTJ flange is a versatile flange that has deep groove cut on the metallic ring. The grooves are compressed with connecting bolts when they are tightened. Large diameter carbon steel flanges cover a larger surface area and are robust in their functioning. These CS pipe flange are very reliable and are durable for long periods. We are the carbon steel flanges manufacturer in India who can customize all our products and deliver them to your doorstep quickly due to our connections with different logistical and supply chains.
