Fiberglass reinforced plastics pressure shells intended to be used in reverse osmosis water treatment unit
1 Scope
This standard specifies the classification, labeling, raw materials, technical requirements, test methods and inspection rules of fiberglass reinforced plastics (hereinafter referred to as FRP) pressure shells intended to be used in reverse osmosis water treatment unit.
It is applicable to FRP pressure shells intended to be used in reverse osmosis water treatment unit made by wound process by taking fiberglass and its products as reinforced material and epoxy resin as base. Its long-term service temperature ranges from -10℃ to +50℃.
