Compatible with small diameter sizes using a water jet.
■Overview of Processing Example Product Name: Teflon Coated Gasket / Dimensions: φ128×φ105×2.8t / This processing example features a Teflon coated gasket with TOMBO No.1120 as the core material, wrapped in PTFE. It was manufactured for a chemical plant. In addition to the heat and steam resistance of the expanded graphite sheet core, the outer PTFE layer provides excellent chemical resistance. Due to its small diameter, high-precision cutting was achieved through water jet processing. ■Product Features TOMBO No.1120 is a joint sheet primarily composed of expanded graphite, with added aramid fibers and NBR. It excels in heat resistance, steam resistance, and corrosion resistance, and is flexible and resistant to scratches. It is suitable for water, steam, oil, exhaust gases, etc., and is widely used in relatively high-temperature flanges and valves in petroleum refining, chemical plants, and power plants.

basic information
■Processing Method Water jet cutting is a water pressure cutting machine that uses high-pressure water to cut materials. It processes by spraying high-pressure water. By changing the injection nozzle according to the processing material, high-quality products can be produced in a short time. Additionally, the dimensional tolerances that are significantly improved compared to traditional manual processing result in stable processing accuracy. The taper of the cutting surface from press processing can also be improved with water jet processing. ■Q&A Q: What is a Teflon-coated gasket? A: It is a gasket with a core material wrapped in PTFE (Teflon). It combines the strength and elasticity of the core material with the chemical resistance of PTFE. Q: Is it possible to manufacture small diameter sizes? A: Yes, high-precision cutting of small diameter sizes is possible with water jet processing. Since molds are not required, it can accommodate small lot sizes. Q: What applications is it suitable for? A: It is suitable for flange seals in chemical plants and food and pharmaceutical lines where chemical resistance and heat resistance are required.
