Metal pall ring packing is a highly efficient chemical packing

Structural features:

Opening design: Two rows of window holes with inward-extending tongues are opened on the ring wall. Each row of window holes usually has five tongues. The tongues are bent inward and point to the center of the ring. They are almost overlapping at the center. The positions of the upper and lower layers of window holes are staggered. The total opening area is about 30%-35% of the entire ring wall area.

Height-to-diameter ratio: Generally, it is a ring structure with equal height and diameter.

Material characteristics:

Stainless steel material: such as 304, 316, 316L, etc., has good corrosion resistance, high temperature resistance, processing performance and high mechanical strength, can resist the erosion of various chemical substances, and can work stably in different chemical environments.

Carbon steel material: low cost, certain mechanical strength and corrosion resistance, suitable for some ordinary chemical occasions that do not require particularly high corrosion resistance.

Special alloy material: such as titanium alloy, Hastelloy alloy, zirconium alloy, etc., has extremely strong corrosion resistance and high temperature resistance, can be used to treat highly corrosive media or use under extreme working conditions.
