Texas Commission on Environmental Quality (TCEQ). Class C Water License Exam

Pressure vessels (tanks) are not recommended for systems with more than how many connections?

1. 1,000 connections

2. 2,000 connections

3. 2,500 connections

4. 3,000 connections

The correct answer is: 2,500 connections

Pressure vessels, such as tanks, are designed to hold fluids under pressure and typically adhere to specific engineering guidelines regarding their safe operation and maintenance. In systems with a high number of connections, the potential for leaks, failures, or pressure loss increases significantly. Beyond a certain threshold, the complexity and potential risks associated with maintenance can outweigh the benefits of using a pressure vessel. The recommendation against using pressure vessels with more than 2,500 connections is based on practical experience. As the number of connections increases, the difficulty in inspection, repairs, and managing pressure integrity also escalates. Systems with excessive connections can encounter numerous points of potential failure, complicating operations and rising the risk of environmental or safety hazards. This threshold ensures that the systems remain safe, manageable, and efficient, while allowing for appropriate oversight and control. Thus, maintaining the integrity and operational capacity of the system remains a priority, aligning with industry standards and safety regulations.
