The quartz tube is mainly used to protect the ultraviolet lamp tube in water. In order to improve the ultraviolet light penetration rate, the international fused silica lamp tube standard is adopted, and the material with low OH composition is used. It has high purity, high transmittance (≥ 90%), stable chemical property, high temperature resistance, and high acid resistance. The shape of quartz tubes can be divided into double ended openings or single cut openings according to the type of ultraviolet sterilization equipment, to avoid contact between the sterilization lamp tube and water. There are various suspended solids attached to the surface of the quartz tube, so it is necessary to install an automatic cleaning device or a manual cleaning device for the quartz sleeve. According to the usage environment, the service life of quartz tubing is 1-3 years.
