Application Scenario

For eccentric reducer pipe leakage, as long as the two pipes have different diameters, the connection part is disconnected due to various reasons, such as pipe aging and land subsidence. If the pipe cannot be removed, you can use a reducer pipe repair clamp for repair.

For eccentric reducer pipe leakage and reducer pipe leakage in various application scenarios, it is also a common repair method to wrap the entire reducer. Baoshuo Pipe Fittings specializes in solving various pipeline problems.

In-depth analysis of the causes of leakage in different diameter pipelines

1.Welding defects and geometric stress concentration

- Misalignment problem: When the misalignment between the flange and the reducer reaches 9mm, a step is formed on the inner wall of the pipe, which causes fluid turbulence and accelerates local erosion.

- Weld excess height: The residual excess height (>1mm) causes fluid backflow and continuous erosion of the weld.

2.Electrochemical corrosion difference

- Corrosion product film difference: The product film in the weld area is loose and porous (easily eroded and peeled off), and the parent material area is dense and stable.

3.Assembly gap causes uniform corrosion

- The flange assembly gap allows the corrosive medium to penetrate. The high velocity area near the fluid side of the gap is mainly eroded, and the low velocity area at the bottom is mainly chemically corroded.

4.Material and manufacturing defects

- Casting inclusions/folds (such as reducing tee fittings), defects expand into cracks during cold extrusion, and leaks during 5.water pressure tests.

- Rubber joint cord layer delamination or rubber aging

6.Flow-induced corrosion

- The turbulent kinetic energy at the point where the diameter of the pipe changes suddenly increases significantly (the flow simulation shows a dark high-turbulence area), and the particle-carrying fluid (such as natural gas containing sand) aggravates the wear.
