304/304L Stainless Steel Butt Weld Concentric Reducer with High Corrosion Resistance for Industrial Pipe Fittings ASME B16.9 Standard
Our butt-weld concentric reducer is a high-performance pipe fitting specially designed for industrial piping systems, available in dual material options: 304/304L stainless steel and carbon steel. As a key component for adjusting pipeline diameter, it adopts a concentric design to ensure uniform fluid transition, minimal pressure loss and no medium accumulation, perfectly suitable for connecting pipelines of different calibers in industrial fluid transmission systems.
Adopting precision manufacturing and butt-weld connection technology, this reducer integrates structural stability, sealing reliability and corrosion resistance, complying with international industrial standards, and widely used in chemical, petrochemical, power, water treatment, and general industrial fields globally.
The dual material configuration fully meets the differentiated needs of industrial projects—304/304L stainless steel for corrosion-prone environments and carbon steel for conventional pressure scenarios—providing customers with cost-effective and performance-oriented solutions for one-stop procurement.

Made of high-quality 304 stainless steel (1.4301), with excellent general corrosion resistance, anti-oxidation and atmospheric corrosion resistance. Cost-effective, easy to weld and process, suitable for conventional industrial pipelines conveying water, oil, gas, steam and other non-corrosive or mild corrosive media.
Low-carbon version of 304 stainless steel (1.4307), with lower carbon content, better intergranular corrosion resistance and weldability. Ideal for high-temperature, high-humidity and mild acid-base environments, such as chemical processing, food and pharmaceutical pipelines, where strict corrosion resistance requirements are required.
Made of high-quality carbon steel (Q235, A105, etc.), with high structural strength, good pressure resistance and cost advantage. Suitable for conventional industrial pipelines with low corrosion requirements, such as water supply, heating, and general fluid transmission systems, effectively reducing project procurement costs.
- Concentric Design for Smooth Fluid Flow: Concentric structure ensures that the centerlines of the large and small ends are aligned, realizing smooth fluid transition, minimizing pressure loss and eddy current, avoiding medium accumulation and scaling.
- Butt-Weld Connection for Reliable Sealing: Adopts butt-weld (BW) connection, which realizes full fusion between the reducer and the pipeline, forming a seamless and integrated structure with zero leakage, strong connection stability and long service life.
- Dual Material Options for Diversified Needs: 304/304L stainless steel for corrosion resistance, carbon steel for cost-saving, covering different industrial scenarios and project budgets.
- Precision Manufacturing & Uniform Wall Thickness: Adopts advanced forging or stamping forming technology, with uniform wall thickness, precise dimensional accuracy and smooth inner/outer wall.
- High Pressure Resistance & Durability: Reasonable structural design and high-quality materials ensure excellent pressure resistance and impact resistance.
- Wide Compatibility & Standard Compliance: Complying with international standards (ASTM, ASME B16.9, DIN, JIS), fully compatible with international standard pipelines.
