1.GMO specially-protected cylinder utilizes high-grade environment-friendly ceramic powder supplied by USA Fluke and Belgium BEKO. Technical engineers have taken so many years to develop the secret recipe that realizes the best mixture ratio with respect to volume of sizing agent, size of particle and amount of adsorption.

2.GMO specially-protected cylinder can bear the pressure and fatigue; pass 260,000 pressure pulse tests pursuant to the strictest international standards; endure acid and base, aging, erosion of hot water and sudden change of temperature; resist corrosion, depositing and contamination
