Material
The materials of reducers include stainless steel reducers, alloy steel reducers, reducer carbon steel reducers, reducer 20 steel q234q345, etc.
Applications
1. When there is a change in the flow rate of the fluid in the pipeline, such as an increase or decrease, and the flow velocity requirement does not change significantly, a reducer should be used.
2. To prevent cavitation at the inlet of the pump, a reducing pipe is required.
3. In order to match with the joints of instruments such as flow meters and regulating valves, reducing pipes are also required.

Low-carbon steel seamless pipe
Low-carbon steel seamless pipes are seamless tubes manufactured from carbon steel with a carbon content of ≤0.25% through processes such as piercing and rolling. Characterized by moderate strength, excellent plasticity and toughness, and ease of processing, they are among the most widely used basic tubular products in industrial applications. Due to their superior workability, they are commonly referred to in the industry simply as "low-carbon steel."
