Zhejiang Daye Flange Co., Ltd. is one of the leading manufacturers and suppliers of ss 304 concentric reducer in China. With abundant experience, we are committed to providing high quality flanges made in China with competitive price. We warmly welcome you to buy durable ss 304 concentric reducer in stock here from our factory. Also, quotation is available.
A core product in the steel butt-weld pipe fittings category, the concentric reducer features a symmetrical frustum structure with perfectly aligned central axes at both its large and small ends. It is designed for coaxial connection and smooth diameter transition in pipeline systems.
SS 304 concentric reducer has two core functions: to connect pipes or equipment ports of different nominal diameters for pipeline bore size adjustment; and to ensure gradual fluid velocity changes during the diameter shift, reducing pipeline vibration and system energy loss.

FAQ
Q: How to confirm genuine 304 stainless steel?
A: Every batch of authentic 304 products comes with a material test report (MTC). For quick on-site verification, you can use a spectrometer to check the content of chromium (Cr ≥ 18%) and nickel (Ni ≥ 8%).
Q: Is there a correct installation direction for concentric reducers?
A: Yes, there is a defined installation orientation. The general rule is to connect the larger end to the upstream side and the smaller end to the downstream pipeline, so that the process fluid transitions smoothly from the larger diameter to the smaller one along the flow direction.
Q: Can concentric reducers be installed on horizontal piping?
A: They are not recommended for horizontal pipelines with liquid drainage or venting requirements. When mounted horizontally, concentric reducers form a low-lying liquid pocket at the bottom and trap gas at the top, which can cause localized corrosion, cavitation, or fluctuations in flow rate and instrument readings.
Q: What is the maximum temperature rating for SS 304 concentric reducer?
A: For ss 304 concentric reducer, the recommended limit for continuous long-term service is 750℃, while it can withstand 800–870℃ under intermittent short-term operating conditions. It delivers stable performance and is fully suitable for routine hot water and low-pressure steam (≤160℃) applications.
