Kalikund Steel & Engineering Company (KSEC) is a proficient manufacturer, supplier and distributor of AISI 4130 - Type 6B Welding Neck Flanges 5,000 PSI. API 6A Type 6B Welding Neck Flanges 5000 PSI manufacturer. A weld neck flange is a type of flange that is manufactured in two designs – the regular type is used with pipes whereas the long type is used in process plant. The AISI 4130 – Type 6B Welding Neck Flanges 5,000 PSI is generally machined from a forging and are typically butt welded to a pipe. Such flanges find their application in hostile environments that have extremely high temperature, pressure, for example, in the manufacturing of Choke & Kill manifolds including Control Panel, Mud manifolds, Cement manifolds, and mud / gas separator.



The AISI 4130 – Type 6B Welding Neck Flanges 5,000 PSI as the name suggests, is successfully used at pressures up to 5,000 PSI. The most common types of Weld Neck Flanges are forged, threaded, screwed and plate. For ensuring high quality, AISI 4130 - Type 6B Welding Neck Flanges 5,000 PSI undergoes a number of tests for the following certifications: Raw Materials Certificate, 100% Radiography Test Report, Third Party Inspection Report, etc. API 6A Type 6B Welding Neck Flanges 5000 PSI stockist. As it is resistant to both cryogenic and high temperatures, this type of flange is widely used in industrial applications like Subsea Wellhead, Well Head Equipments, Oil Exploration, Oil and gas drilling, High pressure jobs, rig project and many more. At Kalikund Steel & Engineering Company (KSEC) we are concerned about customer satisfaction and hence work towards manufacturing high quality products.
