Valve Inspection Equipment Damage Detection

Many people are still not clear about the damage detection of valve testing equipment, so today, let me introduce it to you in detail!

1. Appearance Features

Mechanical damage refers to the process damage caused by collisions, shearing, or cutting during the transportation, transfer, lifting, and stacking of valves. This includes scratches and indentations on the sealing surfaces of flanges with raised or flat seals, such as.

No addressing the drawbacks of the rising surface casting and forgings' sheen.

When these flaws reach a certain depth, they also impact the quality and lifespan of the valves.

2. Inspection Methods

Inspection reveals mechanical damage on the valve surface; the depth of the defect can be measured using a weld gauge or a depth meter.

3. Defect Identification

Radial scratches on the convex or flat sealing flange surface, mechanical damage and defects on the inner flange, and scratches and defects on both sides of the annular flange sealing groove, are among the disadvantages. Collisions can affect the valve method. Blue sealing is generally not permitted.
