Buttweld Reducers Supplied in Concentric and Eccentric Types for Process and Utility Piping Systems Supplier in India
Timex Metals is a principal Buttweld Reducers Manufacturer specializing in the production of high-quality reducers that make piping systems in many industries connect seamlessly. In order to provide superior performance in high pressure and high temperatures environment, our butt weld reducers are designed with precision to achieve excellent durability, resistance to corrosion, and extraordinary functioning. These reducers are designed to the international standards and have both concentric and eccentric models to suit the particular needs of chemical, petrochemical, oil and gas, and other industrial applications.
Buttweld reducers, on the other hand, join pipes of various sizes and ensure smooth flow of piping systems and also control pressure. It is widely required that correct material and grade be chosen and to withstand operating pressure, temperature, and corrosive media. The table with detailed materials and grades will provide adherence to design codes and minimize the risk of installation. This organizational data facilitates cost effective sourcing with a stable B2B platform that trades 347 Stainless Steel Fin Tube and other industrial parts.

- Function in Diameter Transition Control: Buttweld reducers are employed to join piping systems of varying sizes and still maintain a smooth flow nature in the piping system. They facilitate control of the velocity changes, turbulence, and loss of pressure which may be experienced in the event of abrupt size changes when sudden size changes are introduced in process pipelines.
- The Concentric vs Eccentric Design Behaviour: Concentric reducers are normally applied in vertical piping systems where the flow needs to be symmetrical whereas eccentric reducers are mainly employed in the horizontal lines to avoid air pockets or liquid buildup. Proper choice of reducer enhances the effectiveness of the system and reduces the weaknesses of cavitation or uneven flow distribution during operations.
- Process of Manufacturing, Dimensional Integrity: These reducers are produced by means of hot forming, pressing or welding to guarantee uniformity in wall thickness and exact end dimensions. Meeting such standards as ASME B16.9 would guarantee appropriate weld fit-up, alignment and structural force in installation and service.
- Service Reliability: Material Grades: The Buttweld reducer material comes in Carbon Steel, Stainless steel, Alloy steel and Nickel Alloy grades based on the pressure, temperature and the exposure to corrosion. It has very high leak resistance and long life due to their full welded material, which is applicable in refineries and power plants, as well as in chemical processing units.
| Material | Grade | Standard | Diameter Range | Length | Condition | Density | Typical Use |
|---|---|---|---|---|---|---|---|
| Inconel | 600 | ASTM B166 | 6 mm – 300 mm | Up to 6 m | Hot Rolled / Cold Drawn | 8.47 g/cm³ | High-temperature components |
| Inconel | 625 | ASTM B446 | 6 mm – 250 mm | Up to 6 m | Solution Annealed | 8.44 g/cm³ | Corrosion-resistant parts |
| Inconel | 718 | ASTM B637 | 8 mm – 200 mm | Up to 6 m | Aged / Annealed | 8.19 g/cm³ | Aerospace & turbine parts |
| Inconel | X-750 | ASTM B637 | 10 mm – 180 mm | Up to 6 m | Solution Treated | 8.28 g/cm³ | Springs, fasteners |
Inconel round bars are used in situations that require maintenance of strength in extreme temperature and strain conditions. Grades choice also affects the creep resistance, oxidation behaviour and machinability in the fabrication. Downstream machining and fatigue performance depend on dimensional tolerance and condition. Forged Round Bar can be considered as an option in heavy-duty mechanical assemblies when the grain structure refinement and increased impact resistance are necessary: Inconel round bars can be considered as well.
Type of Sub-products

Concentric Buttweld Reducer Concentric Buttweld Reducer
Concentric reducers align the centerlines of both pipes, ensuring smooth vertical flow. They're used in pump discharge lines and vertical piping systems for steady pressure control.

Eccentric Buttweld Reducer Eccentric Buttweld Reducer
Eccentric reducers have an offset centerline, helping avoid air pockets in horizontal pipelines. They're ideal for chemical drains and fluid handling systems where elevation matters.
