Bauer ring packings are primarily available in three materials: ceramic, metal, and plastic. Metal materials include 304, 316, 316L, carbon steel, 201, 410, etc. Plastic materials include PP, RPP, CPVC, PVDF, PVC, PTFE, FEP, PFA, etc. Plastic Bauer ring packings typically come in three shapes: Chinese character, letter, and plus sign, along with other special-shaped Bauer rings. The wall-hole design of Bauer rings significantly improves the gas and liquid distribution performance compared to Raschig rings, particularly maximizing the utilization of the inner surface area of the rings.

● Shandong Chlor-Alkali Project CPVC Pall Ring Filler, DN50, Chlorine-Resistant Material Plastic Pall Ring. The product mainly addresses the corrosion issue of tower fillers requiring resistance to hot alkali and hypochlorite alkali over 60~90°C in the chlor-alkali production process.

●General metal and ceramic packings are not resistant to alkaline corrosion, leading to phenomena such as spalling and powdering, causing debris blockages that impair the separation efficiency of tower equipment and necessitate frequent replacements. Standard plastic packings are not resistant to hypochloric acid corrosion, while most foreign countries use polytetrafluoroethylene and polyvinylidene fluoride materials, although they are difficult to form and expensive.

● CPVC ball ring packing and Taylor梅花ring completely overcome the above shortcomings. It can withstand alkali corrosion above 60~90°C and also resist sodium hypochlorite corrosion. The material cost is moderate and can fully meet the requirements of the chlor-alkali industry.

● CPVC Bower ring packing offers advantages such as high throughput, low resistance, high separation efficiency, and great operational flexibility. Under the same pressure drop, the processing capacity can be up to 50% greater than that of Raschig rings.

Purpose of Baume Ring Filler:

Shandong Chlor-Alkali Project CPVC Pall Ring Filler, DN50, Chlorine-Resistant Material Plastic Pall Ring, is particularly suitable for distillation, absorption, and washing towers in the oil, chemical, chlor-alkali, coal gas, and environmental protection industries at medium and low temperatures (60-150°C). It is also used in carbon dioxide degassing towers, ozone contact reaction towers, and other reaction towers as contact filler. Ceramic Pall Ring Filler is suitable for acid mist purification towers in carbon dioxide degassing towers, ozone contact reaction towers, and other reaction towers as contact filler.

Metal Bellows Filler Application: Suitable for vacuum rectification towers, handling heat-sensitive, easily decomposable, prone to polymerization, and carbon deposition materials.

PVC (Polyvinyl Chloride): Rigid thermoplastic with moderate usage temperature; resistant to alkalis, acids, salt solvents, oil, fats, diesel; temperature resistance ≈ 60°C, density 1,38 g/cm³, color: transparent white.

CPVC (Chlorinated Polyvinyl Chloride): Resistant to corrosion from acids, alkalis, salts, oxidizers, etc., density 1.55 g/cm³, gray in color. The CPVC pall rings from Binzhou Chlor-Alkali Project, with DN50 and chlorinated material, are commonly used in fluoride alkali industry projects and are highly resistant to chlorine gas.
