DIN PN25 PL
Global Standard Compliance: Complies with international standards (ASME B16.5, EN 1092-1, JIS B2220, GB/T 9119) and regional specifications, ensuring interchangeability with global pipeline components for cross-border trade.
Low Maintenance Requirements: Durable material selection and stable structure minimize wear and tear, reducing maintenance frequency and replacement costs. Easy to disassemble an replace when needed.
Lightweight & Space-Saving: Compact structure and lighter weight compared to welding neck flanges, saving installation space and reducing transportation costs, suitable for limited-space pipeline layouts.
1. Overview
The Slip On Flange (abbreviated as PL Flange) is a widely used piping connection component characterized by its simple structure, cost-effectiveness, and easy installation. Designed to slide over the pipe end and secure via fillet welding, it is ideal for low to medium-pressure industrial pipeline systems. Compliant with global standards, it is extensively applied in water supply, heating, chemical, oil & gas, marine, and general industrial sectors.
