The order includes PL flanges for welding manufactured in accordance with both JIS and EN standards, meeting different pressure classes and nominal sizes required for the project.

These flanges are widely used in industrial piping systems for secure and economical pipe connections.

Supplied Plate Flange Specifications

The delivered plate flanges cover multiple standards and pressure ratings:

• JIS Plate Flange 40A 16K, material SF440, JIS B3201

• EN Plate Flange DN65 PN16, material SF440, EN 1092-1

• JIS Plate Flange 50A 10K, material SS400, JIS B3101

• JIS Plate Flange 80A 16K, material SF440, JIS B3201

• EN Plate Flange DN100 PN16, material SF440, EN 1092-1

All products are manufactured from carbon steel equivalent to 20# steel, ensuring reliable mechanical strength and stable welding performance.

Material and Standard Selection

The use of SF440 and SS400 carbon steel grades provides a good balance of strength, ductility, and weldability.
By supplying flanges in both JIS pressure ratings (10K / 16K) and European PN16 standard, Haihao Group supports international projects that require compatibility with different piping systems.

Each plate flange is designed for butt welding, ensuring solid joint integrity during long-term operation.
