Pipe and End Caps are widely used in various industries, including oil and gas, petrochemical, water treatment, and construction. They are essential in sealing the ends of pipes, preventing contaminants from entering the system and ensuring a secure, leak-proof connection. End caps are also used during pipe storage and transportation to protect the interior from debris. In plumbing systems, they prevent water leakage and safeguard against pressure loss. Additionally, they are employed in pressure vessels, heat exchangers, and other critical systems requiring pressure containment and corrosion resistance.
