Carbon Steel Flanges and CS Blind

06 Sep.,2023

 

ASME B16.5 CS Blind Flanges and Weld Neck Flange manufacturer in India

Flanges are used to connect 2 ends of a pipe or to end a pipe. They are available in various materials. Carbon Steel Flanges are one such type of flange that is usually made up of carbon steel. This material provides properties such as resistance to corrosion, excellent durability, and finishing in goods. They are available in various types. For instance,Carbon Steel Blind Flanges are used to terminate the pipe. High grade raw material is used to manufacture these flanges. They have a carbon content in the range of 0.25% to 0.60%. Due to the high volume of carbon and manganese, the fabrication of the product is excellent and ductility is also good. 

There is another type of flange that is known as killed Carbon Steel Forged Flanges. They are destroyed in the melting process. Due to the addition of manganese, silicon, and aluminum during the production of steel, deoxidation takes place. Carbon Steel Plate Flanges are welded onto the pipe which helps in bolting and connecting one pipe to the other. It displays good ductility, and toughness. These Carbon Steel Pipe Flanges also work well in low temperatures. They are used in fuel and water pipelines. The cost of these flanges ranges between Rs 398 to Rs 689. 

To strengthen and harden the steel and cast iron alloy Carbon Steel Slip On Flanges are passed through a process known as quenching. They are used in various construction, engineering, and petrochemical industries. The outer diameter of the slip on flange is also welded. Carbon Steel Weld Neck Flanges have a neck extension at the end. This type of flange is directly buttwelded to the pipe to provide a natural connection. Carbon Steel Flanges manufacturers in India recommend the use of these flanges when the conditions are critical and severe.
