Description
At CIVMATS, you can always find the desired stainless steel reducer to match your specific demands. Meanwhile, for standard size stainless steel reducers, they are readily in stock, matchable to the same-size stainless steel pipes and fittings for a whole project. One stop purchase can save you time and cost at CIVMATS. With accumulated industry experience, we can also provide valuable suggestions to your project upon consultation for free. The most common grades (in stock) are 304 & 316L, but we have in our production range the following grades:
Stainless steel: 304(L), 304H, 316(L), 316H, 316Ti, 309, 310S, 321(H), 317(L), 347(H), 254SMO, 904(L);
Duplex Stainless Steel: S31803, S32205 (2205), S32750 (2507), S32760
Our stainless steel reducers can be applied to chemical engineering, building industry, water supply, drainage system, petroleum industry, light and heavy industries, refrigeration, sanitation, plumbing, fire protection, electric power engineering, aerospace, shipbuilding and related projects.
Stainless steel centric reducers are commonly seen used for air flow or vertical liquid flow. In comparison, stainless steel eccentric reducer are applied to the situation where air and liquids are flowing together. In comparison, stainless steel concentric reducers are more common and widely used.
Our stainless steel reducer size can range from DN15 to DN3000, and thickness from SCH5S to XXS (referring to ASTM B36.10/B36.19). At Civmats, customized stainless steel reducers are also available as per your specific needs.

Features
- Designed to join piping systems for a change in inner diameters of two adjacent stainless steel pipes. Stainless steel reducers, due to good corrosion resistance and heat resistance, are always found assembled in the power plants and chemical industries. With stainless-steel reducers, the piping system becomes compact, safe, durable, and free from any type of leakage.
Applications
- Petroleum, chemical industry, natural gas, power, shipyard, paper making, bioengineering, pharmacy, construction, sewage system, etc.

By Air
At CIVMATS, the most common transportation for overseas orders is by sea. Other transportation methods, such as by train, by air, or by the combination of the above mentioned modes, are also available as per your choice. Ultimately, we will follow your demands.
FAQ
Can you produce stainless steel reducers as per our drawing?
Yes, customization is available upon your consultation.
Can you do polishing inside and outside on stainless steel reducer?
Yes, we can produce sanitary reducers as per your demand.
Can you produce non-standard stainless steel reducers?
Yes, customization is possible with drawings, whether in terms of grades or dimensions.
Can you produce as per European standard?
Yes, we can produce as per European standard, American Standard and GB standard.
Do you have MOQ?
Nope, small quantity is also acceptable.
Can you speed up delivery time, like a week?
Usually, we need a month for shipment. To speed up, we can shorten the delivery time to 2 weeks. 1 week is unlikely unless there is stock. Please mange your time wisely and try to avoid urgent orders.
