Wall Thickness: SCH XS.

Material: ASTM A 234 WPL3

Standard: ANSI B16.9.

Certificates: CE, ISO, PED, TS, BV, CQC.

There are two types of reducers: concentric reducers and eccentric reducers. The shape of the eccentric reducer is asymmetric, and the centers of the two ends are offset from each other. This design allows for gradual transitions between pipes of different diameters, while changing the elevation or position of the pipes. Eccentric reducers are usually used in situations where vertical or horizontal adjustment of the pipeline is required to ensure optimal flow rate. They can be applied in industries such as oil and gas pipelines, sewage treatment, chemical manufacturing, and wastewater management.

Piping systems usually require connecting pipes, elbows, tees and other pipe fittings. Reducer pipe fittings can realize the interconnection between different sizes and types of pipes and ensure the integrity of the piping system. At the same time, it can reduce the risk of leakage in the pipeline system and improve the safety of the pipeline system.

 

When connecting pipe systems, reducers can control the fluid flow of the pipe system. By selecting appropriate reducer fittings and pipes, the flow stability of the pipeline system can be ensured and insufficient or excessive flow can be avoided.

 

 

Reducer fittings play an important role in the construction and maintenance of pipeline systems. It can connect pipelines of different sizes and types, maintain pipelines, adjust pipeline directions, and ensure the flow stability of the pipeline system. At the same time, its high strength and reliability can also make the pipeline system achieve better operating results.
