Plate-type flat-weld flange

Product Overview

PL plate‑type flanges are widely used slip‑on flanges, suitable for general‑purpose industrial piping systems. Offering excellent cost performance and easy installation, they can be employed to connect pipelines, valves, pump bodies, and various types of equipment. By tightening the gasket on the sealing surface with bolts, a leak‑free seal is achieved, making them particularly well suited for applications that require simple installation and regular maintenance.
