What are "seal" welds used for?

Seal welds are specifically employed to prevent leakage from certain pressure vessel components, such as handholds or flanges. These welds provide a tight seal that ensures the integrity of the pressure vessel by eliminating gaps or openings where fluids or gases might escape. Ensuring a leak-proof assembly is critical in maintaining safe operating conditions for pressure vessels, especially in refrigeration and other industrial applications.

The nature of seal welds is such that they are designed to withstand the pressure and environmental conditions typical for the components they secure. By effectively sealing these areas, operators can ensure compliance with safety regulations and avoid potential hazards associated with leaks. Proper application of seal welds can help in maintaining the overall efficiency and safety of refrigeration systems.
