About us
-
Lianyungang Haisheng Quartz Tech Co. Ltd stems from the former state-owned Donghai Quartz Glass Product Factory. Haisheng Quartz(abbr. Lianyungang Haisheng Quartz Tech Co.ltd) is a member of Quartz Industry Associate, and it covers R&D, production and marketing. At present there are 6 production line. Annually 700t quartz tube(/fused silica tube) and quartz silica plank(quartz plate, quartz wafer, quartz substrate) are being produced.
A novel technique about vertically producing quartz plate with fused silica was invented by Haisheng Quartz Co., and the intellectual property right is held.
Main products include quartz plate(/quartz plank) 2¡«20mm thick, quartz tube(/fused silica tube) diameter 2.5¡«100mm, quartz rod, UV tube, none-ozone tube, low OH tube, opaque tube, etc.

Standard quartz tube
We adopt vertical continuous fusing technique to produce pure transparent fused quartz tube with low hydroxyl (i.e. -OH), which can be used in halogen lamp, metal-halogen lamp, mercury lamp, heater, automobile light, stage illumination, printer, water sterilization, lab instrument, etc.
Dimension: outer diameter 3~30mm, thickness 1~4mm, length < 1500mm. Hydroxyl(-OH) percentage can be customized to be 10ppm/5ppm/2ppm, respectively. Polishing, annealing, frosting, twisting processes are also provided as customer's will.
