Kalikund Steel & Engineering Company (KSEC) is a leading manufacturer, supplier, and distributor of AISI 4130 Concentric Reducers in India. A reducer is used to join two pipes of different diameters. Depending on the use, a reducer is manufactured in two different shapes – Concentric reducer and Eccentric reducer. A concentric reducer is cone-shaped and is used to join two pipes with a shift in diameters. This reducer can be used when there is a single as well as multiple diameter changes. Our AISI 4130 Concentric Reducer undergoes strict and rigorous testing and examination for ensuring the product safety and reliability. The tests may be include hardness test, mechanical test, positive material identification test, chemical test and a few more.
We manufacture AISI 4130 Concentric Reducer which are majorly used for high pressure applications like Drilling Equipments, Onshore offshore drilling, Rig Projects, deep water riser system, Manifold Equipments, Debris/ junk catcher manifold and many more such areas. The AISI 4130 Concentric Reducer comes with a standard pressure ratings of 7.5k-10.5k PSI. Because of its high temperature resistance this reducer is used in the manufacturing of Choke & Kill manifolds including Control Panel, Mud Manifolds, and Cement Manifolds, manufacturing of Mud / Gas Separators, Oil & Gas and Oil Exploration industries, production of Pipe Line End Terminations and Manifold Equipment’s. At Kalikund Steel & Engineering Company (KSEC), we keep a stock of AISI 4130 Concentric Reducers so that the customer can avoid delay in deliveries, hence winning customer acclamations.
