Why I do not recommend using flange spray shields
-
PP flange guards are prone to aging and have a single size (cannot cover high-pressure flanges properly). The upper and lower shells are easy to crack.
-
Corrosion risk to equipment: spray shields are typically used to prevent material splashes, but they are not fully sealed, and they can collect water in rainy or high-humidity environments. If water accumulates inside the shield, particularly where metal parts like bolts and flanges are exposed to moisture, it may accelerate rusting. Metal gaskets, although strong under pressure, are also susceptible to corrosion, especially in the humid environment inside the splash shield. Therefore, spray shields are not suitable for long-term use in damp conditions.
-
Leak detection is difficult: Leaks usually start small—flanges, pipes, and welds often begin leaking at tiny points and don’t suddenly result in large splashes. Over time, acid- and alkali-resistant splash shields become blackened, obscuring the protected parts and making it hard to spot leakage signs promptly. Leaks often begin as tiny drips, hard to detect, and can be overlooked before water accumulation or corrosion occurs. By the time you notice water dripping from the shield, the problem has escalated, making it hard to tighten or repair the leakage.
-
Static electricity risk: Spray shields may lack anti-static features in some cases, and static electricity can cause sparks or electrical failures, especially in environments with chemicals or flammable gases.
Eliminating these issues is key to enhancing the factory’s prevention system, improving efficiency and safety, and reducing maintenance costs—rather than constantly repairing.
