Our huge in-house production capacity through our in-house manufacturing plant helps us to create a chain of quality products that may dispense their valuable services to your direct industrial application but may never
dier in quality. We are manufacturers, suppliers, and exporters of Concentric Reducers, a type of Pipe Reducer that fastens pipe sections on the same axis and is conical in shape. These pipe fittings have varying ends and can join unequal diameter pipes on different pipe sections falling on the same axis. Our Stainless Steel Concentric Reducers are tested and certified for accuracy,
durability, and quality, and play a key role in the conveyance of semi-liquid mixtures and abrasives in the liquid state. Our ANSI B16.9 Concentric Pipe Reducers are suitable for use in the plumbing and automobile industry.
The company manufactures, supplies and distributes a wide range of fittings, such as elbows, tees, reducers, caps, bends and many others from 1/2″ to 120″ diameter in all material grades, according to international standards and clients’ requirements.
The target markets can be divided into up/mid/downstream, which includes onshore and offshore/subsea plants, oil & gas pipelines, refineries, and power generation such as nuclear and thermal power plants. The company manages the whole cycle of production, distribution and after-sales services in all these markets. EPC companies represent the largest part of its capacity. Close co-operation with clients gives the company the opportunity to develop the market and the products in line with trends in the field of energy.
