Carbon Steel Concentric Reducer

Carbon Steel Concentric Reducer

Since 1998, Om tubes and fittings have represented quality, trust and reliance. We believe key to success is in innovation.

Om tubes and fittings are specialized manufacturers, dealers of premier quality Carbon Steel Concentric Reducers. We majorly emphasize on consistent improvement and provide with the best service ever. Our processes make us stand out from the rest of the lot. At Om tubes, our process consists of procedural development cycle: designing (customization provided), the engineering process, the machining process, assembling the parts, testing (hundred percent in house), packing and warehousing, logistics and documentation process. We stock the largest inventory of products ready for immediate delivery. We have the best team from manufacturing to dispatch, who have made us what we are today. We provide concentric reducers in various grades, size, cuts, according to the customer’s specifications. Our adherence to strong values, has made our brand stand up amongst the others. We regularly review our processes, and maintain a strong, stable management team. We have a pioneering way of delivering our products, along with the affordable price of our products, which makes us a good choice.

A reducer is the component in a line that reduces the pipe size in diameter from a larger to a smaller bore. Carbon Steel Reducers are preferred due to their high tensile strength, smooth internal finish and hardness. Designed with precision, makes these carbon steel welded tubes suitable in high pressure applications.  The length of the reduction is usually equal to the average of the larger and smaller pipe diameters. A reducer can be used either as nozzle or as diffuser depending on the density of the flow. A reducer allows for a change in diameter of pipe size to meet hydraulic flow requirements of the system, or to adapt to existing piping of a different size. These fittings are manufactured in inch and metric size. The design of pump inlet piping defines the resulting hydraulic conditions experienced at the pump inlet/impeller. A reducer fitting is typically used in pump station pipe work to reduce the size of the suction pipe to match the size of the pump suction end flange. Reducer fittings used in pump inlet pipe work are divided into two types—concentric and eccentric reducers. The two types of reducer fittings can be described as:

  • Concentric reducer—The reduction of the pipe size is achieved by decreasing the diameter of the fitting at a constant rate over a specified length, maintaining symmetry around the fitting.
  • Eccentric reducer—The reduction of the pipe size is achieved by decreasing the diameter of the fitting at a constant rate over a specified length, maintaining one side of the fitting horizontally The non-uniform velocity distribution results from the acceleration of flow along the eccentric reducer’s sloped side resulting in an unbalanced force that is not addressed.


The ANSI/HI 9.8 American National Standard for Pump Intake Design (P21, 1998) eliminates any reference to the possible flow distribution that could be generated by the reducer. This requirement can be used to assess the extent of flow disturbance caused by a reducer. ANSI/HI 9.8 also recommends a maximum flow velocity of 2.4 meters per second (m/s) in the suction pipe work.

ANSI/AWWA C208 American Water Works Association Standard – Dimensions for Fabricated Steel Water Pipe Fittings (P7, 2008) directs the length of a reducer (Lr) to be calculated with the following formula:

Equation 1
Lr = 4 (DL – Ds)
Lr = Length of the reducer.
DL = Larger pipe diameter.
Ds = Smaller pipe diameter.
ASTM A403 / ASME B16.9: Simultaneously, it also has to fulfill the ASTM and ASME requirements.

Each time we perform the processing, the tube needs to be cut, cleaned and heat treated before the next one can commence. Stainless steel is basically an all in one metal because of its properties, which makes it a common choice among-st the producers. We are a specialization in the production of high quality, affordably priced stainless steel concentric reducers.

  • Value added services.
  • Epoxy and FBE coating.
  • Electro polish.
  • Draw and expansion.
  • Bending and buffing.

The processing starts with: cleaning, straightening, cutting, testing, printing, packing and shipment of the product. The processing starts with: cold pilferage i.e. reducing the size the metal tubes, then comes cold drawing i.e. where each fitting is machined before its use, then comes shaping, cleaning, testing (in house), Inspection of the quality, printing, packaging and then shipment to the ports. Our manufacturing process involves the following steps: transformation of raw materials into steel bars, transformation of steel bars into mother pipe, which is manufactured in different types of rolling mills, then these pipes are converted into concentric reducers through automated machine process. Our fittings are threaded and undergo non-destructive testing before delivery to the customer.

Industries served include aquatic, automotive, biotechnology, pharmaceutical, chemical processing, food and beverage, life sciences, mining, OEM, power and utilities, pulp and paper, steel and metal finishing, and water and wastewater treatment. Suitable for a wide variety of processes.

We aim at providing professional customer service with one-stop purchasing along with superior quality control, competitive price, fast lead time and convenient transportation. We enjoy global remarkable presence in many countries, due to our merchandisers. We provide with same day shipping of goods against the receipt of purchase order. The customer just has the need to share their interest through our online link, and rest can be left to us. Om tubes supplies with following value added benefits:

  • Production flexibility.
  • Quality seamless tubes.
  • Trustworthy partnership.

Products are packaged to ensure there is no damage during transit. We stock huge, to facilitate prompt delivery. All our products are packed in specialized carton boxes with brand identity labeling along with personal checking. We possess a perfectly developed transport system by which we can deliver goods directly and safely to the customer. The products are covered by plastic caps, to prevent damage during transit. All the bags are secured with a unique identification number, to ease the assembling process. We have an order tracking system, through these codes. We give emphasis on packaging as much as production, to provide our customers with seamless buying experience.
