A German chemical enterprise customized SS304 stainless steel folded cartridge to solve high temperature filtration problems
A German fine chemical enterprise has successfully achieved high efficiency filtration of high temperature and strong corrosive media by customizing SS304 stainless steel mesh folded cartridge (1.25-inch NPT interface/310mm total length/5μm precision). This article analyzes its customized solutions in the material matching, structural suitability and filtration efficiency of the three dimensions of technological innovation.
1: SS304 material to ensure the stability of extreme working conditions
● Argument: The customer's production environment involves 80 ℃ acidic media, ordinary carbon steel cartridge corrosion perforation in 3 months. The customized SS304 material has been tested by a third party and shown to last 2400 hours without corrosion in hydrochloric acid solution with pH value of 1.5, and the service life has been increased to 18 months.
● Data support: Salt spray test meets the ASTM B117 standard of 1000 hours, Vickers hardness HV210-240 to ensure structural rigidity.
2: Accurate size design for complex piping systems
● Argument: For customer DN150 piping system, the customized bottom end cap with 150mm diameter is seamlessly connected with the piping to shorten the installation time by 60%. The top 1.25-inch NPT inner teeth design passed API 598 sealing test, and the pressure loss is reduced to 0.08MPa.
● Measured data: 310mm total length design makes the effective filtration area up to 0.85 square meters, which improves the flux by 35% compared with the standard model.
3: 5μm gradient filtration to improve process purity
● Argument: Through the 3-layer gradient folding process (outer layer 20μm → middle layer 10μm → inner layer 5μm), the catalyst particles are intercepted while maintaining a stable flow rate of 0.5m³/min. Customer feedback product impurity retention rate increased to 99.97%, batch product qualification rate exceeded 99.5% industry benchmark.
● Validation data: Tested by ISO 16890 standard, the filtration efficiency of 5μm particles reaches 99.93%, and the differential pressure curve shows that the performance degradation in 2000 hours of continuous operation is <5%.
This case verifies the technical advantages of customized stainless steel mesh folded cartridge under special working conditions: SS304 material guarantees extreme environmental reliability, precise size design improves system adaptability, and multi-layer gradient filtration realizes high efficiency separation. 500 customized cartridges delivered in batch marks that China's precision filtration element manufacturing has reached the standard of the international high-end market, and it provides reusable filtration solution templates for the chemical industry, pharmacy, and other industries. solution template for chemical and pharmaceutical industries.
