Large diameter stainless steel stepped ring packing

Large diameter stainless steel stepped ring packingThe specification model is 90 * 45 * 1.2SS, which is a special type of large-diameter stainless steel stepped ring packing. The stepped ring material we use is 304 stainless steel, which is a widely used chromium nickel stainless steel [1]. As a widely used steel, it has good corrosion resistance, heat resistance, low-temperature strength, and mechanical properties; Good hot workability such as stamping and bending, without heat treatment hardening phenomenon (operating temperature -196 ℃~800 ℃). Corrosion resistance in the atmosphere, if it is an industrial atmosphere or heavily polluted area, it needs to be cleaned in a timely manner to avoid corrosion. Suitable for food processing, storage, and transportation. Has good processing performance and weldability. Plate heat exchangers, corrugated pipes, household items (Class 1 and 2 tableware, cabinets, indoor pipelines, water heaters, boilers, bathtubs), automotive parts (windshield wipers, mufflers, molded products), medical equipment, building materials, chemicals, food industry, agriculture, ship components, etc. 304 stainless steel is recognized as food grade stainless steel.

Large diameter stainless steel stepped ring packingThe limit ensures that its torus is perpendicular rather than parallel, and this design has more prominent advantages in mass transfer. Because the reaction efficiency depends on the size of the contact surface. The design of parallel surfaces will prevent the inner side of the ring from coming into contact with liquid, thus forming a dry surface. Dry surface plays almost no role in mass transfer, but the vertical design of the metal stepped ring greatly reduces the possibility of dry surface, thereby effectively improving efficiency.Generally, the flux of stepped ring packing can be increased by 10-20% and the pressure can be reduced by 30-40% compared to Bauer ring packing. The separation efficiency varies depending on the specific process.
