Applications
Low-Pressure Static Systems:
(1)Water tanks, ventilation ducts, HVAC ducts (≤Class 150).
(2)Low-pressure coolant lines in machinery.
(3)Non-critical drain pipes.
Cost-Driven Projects:
(1)Budget infrastructure (e.g., agricultural irrigation).
(2)Temporary piping or prototype testing.
Non-Pressure Applications:
(1)Blanking off pipe ends (blind flange function).
(2)Equipment covers (e.g., filters, tanks).
Low-Fluid-Risk Environments:
Air, water, inert gases at ambient conditions.
