Final answer:
The Mechanical Code mandates that pipings and pressure vessels undergo hydrostatic testing for tightness, a critical safety measure performed by the installing contractor.
Step-by-step explanation:
The Mechanical Code requires that all pipings and pressure vessels be hydrostatically tested for tightness by the installing contractor hired by the building owner. A hydrostatic test is a way in which pressure vessels such as pipelines, plumbing, gas cylinders, boilers, and fuel tanks can be tested for strength and leaks.
The test involves filling the vessel or pipe system with a liquid, usually water, and pressurization of the vessel to the specified test pressure. This ensures that all welded and jointed areas are thoroughly checked for any potential leaks or weaknesses. It's a crucial safety procedure to guarantee the integrity of the equipment that must contain fluids under pressure, thereby safeguarding property and lives against possible failure.
