We manufacture and carry various hydrostatic pipeline plug designs, including expansion plugs, and mechanical plugs, among others. While pipe plugs may serve different purposes depending on the operator's application, they are classified as pipe fittings due to their function within piping systems.

Hydrostatic testing is a crucial quality assurance measure, especially during pipeline construction, maintenance, or repairs, ensuring compliance with industry standards and regulations while enhancing safety and reliability.
