What is the strength index of structured packing

The strength indicators of structured fillers mainly include mechanical strength, compressive strength, crushing strength, etc., as follows:

Mechanical strength

The mechanical strength of structured packing is closely related to its material. Metal fillers (such as stainless steel, titanium alloy) have the highest mechanical strength and can withstand the impact of high pressure and high-speed fluid 1; Plastic fillers (such as polypropylene, polyvinyl chloride) are second, with good toughness but low pressure resistance 1; Ceramic fillers (such as alumina ceramics) have the lowest mechanical strength, but can achieve higher crushing strength (such as ≥130MPa) through special processes.

Compressive strength

The compressive strength of plastic structured fillers varies by model, such as:

SB-125Y compressive strength > 6.0N /mm²

SB-500Y compressive strength > 8.0N /mm²

The compressive strength of some enhanced plastic fillers can reach > 10.0N /mm²3.

Crushing strength and hardness

The crushing strength of ceramic structured fillers is usually required to be ≥130MPa and Mohs hardness ≥7 to ensure structural stability in high temperature and high pressure environment2. Due to the material characteristics, the compressive strength and wear resistance of metal fillers are significantly better than that of plastics and ceramics.

Other intensity related indicators

The bulk density and shape factor of the filler also affect its mechanical properties indirectly. High bulk density usually means higher structural densification and bearing capacity 4.
