High Temperature Large Diameter High Borosilicate Glass Tubes

Product DescriptionThe tubes are with diameter ranging from Φ9mm to Φ160mm and wall thickness from 1mm to 5mm,The glass can be adapted to various products, like glass instrument tubes, domestic glass ware, glass rod, chemical tubes, medium-high temperature Solar thermal tubes, rough solar vacuum tubesProduct ApplicationThe adaptability of glass allows it to provide target solutions for many related industries1. High Borosilicate Glass in Daily Usage High borosilicate glass is considered to be the healthiest and most safe daily usage glass  for it doesn't contain or generate any matters harmful to the body in usage. It is also featured by anti-temperature difference, non-bursting rate, good gloss, etc.2. High Borosilicate Glass in LaboratoryHighly resistant to thermal shock and heat; resistant to water, strong acids, alkali and saline solutions. 3. High Borosilicate Glass in LightingHigh optical and cosmetic quality, no extra reflection and refraction. Tight geometric tolerances allows for stable manufacturing process and easy assembly. Especially low thermal expansion, high resistant to thermal shock and high chemical resistance make it optimally suitable for use in adverse conditions.Product AdvantagesOur High borosilicate glass tubes has feature of low expansion rate, high temperature resistance, high strength, high hardness, high light transmittance, and high chemical stability. We are source tube supplier for famous brands like Starbucks,  Xiaobaixiong, and Wuliangye. The high quality has won us unanimous favorable comments from customers.Product ParametersPhysical PropertyNo.Physical PerformanceNumerical ValueUnit1Coefficient of meamlinear thermal expansion (20ºC-300ºC)3.3+/-0.110-6K-12Transformation temperature525+/-15ºC3Softening point820+/-10ºC4Working Point1260+/-20ºC5Density at 20ºC2.23+/-0.02g/cm36Mean thermal conductivity(200-100ºC)1.2w/m2k7Refractive index0.921Main Composition SiO2B2O3Na2O+K2OAi2O3811342Chemical PropertyHydrolytic Resistance at 98ºCISO719-HGB 1Hydrolytic Resistance at 121ºCISO720-HGA 1Acid Resistance ClassISO1776-first classGlass Tubing Size(mm)ODWall Thickness(Thin)Wall Thickness(Thin)Wall Thickness(Medium)Wall Thickness(Heavy)Wall Thickness(Super Heavy)4+/-0.40.5+/-0.10.8+/-0.1   5+/-0.40.5+/-0.10.8+/-0.1   6+/-0.40.5+/-0.11+/-0.11.5+/-0.22+/-0.22.5+/-0.37+/--0.40.5+/-0.11+/-0.11.5+/-0.22+/-0.22.5+/-0.38+/-0.40.6+/-0.11+/-0.11.5+/-0.22+/-0.22.5+/-0.39+/-0.40.6+/-0.11+/-0.11.5+/-0.22+/-0.22.5+/-0.310+/-0.40.6+/-0.11+/-0.11.5+/-0.22+/-0.22.5+/-0.311+/-0.40.6+/-0.11+/-0.11.5+/-0.22+/-0.22.5+/-0.312+/-0.40.6+/-0.11+/-0.11.5+/-0.22+/-0.22.5+/-0.313+/-0.40.6+/-0.11+/-0.11.5+/-0.22+/-0.22.5+/-0.314+/-0.40.6+/-0.11+/-0.11.5+/-0.22+/-0.22.5+/-0.315+/-0.40.6+/-0.11+/-0.11.5+/-0.22+/-0.23+/-0.316+/-0.40.7+/-0.11.2+/-0.21.8+/-0.22.4+/-0.23+/-0.317+/-0.40.7+/-0.11.2+/-0.21.8+/-0.22.4+/-0.23+/-0.318+/-0.40.7+/-0.11.2+/-0.21.8+/-0.22.4+/-0.23+/-0.319+/-0.40.7+/-0.11.2+/-0.21.8+/-0.22.4+/-0.23+/-0.320+/-0.50.8+/-0.11.2+/-0.21.8+/-0.22.4+/-0.23+/-0.321+/-0.50.8+/-0.11.2+/-0.21.8+/-0.22.4+/-0.23+/-0.322+/-0.50.8+/-0.11.2+/-0.21.8+/-0.22.4+/-0.23+/-0.323+/-0.50.8+/-0.11.2+/-0.21.8+/-0.22.4+/-0.23+/-0.324+/-0.50.8+/-0.11.2+/-0.21.8+/-0.22.4+/-0.23+/-0.325+/-0.50.8+/-0.11.2+/-0.21.8+/-0.22.4+/-0.23.2+/-0.326+/-0.50.9+/-0.11.4+/-0.22+/-0.22.6+/-0.33.2+/-0.327+/-0.50.9+/-0.11.4+/-0.22+/-0.22.6+/-0.33.2+/-0.328+/-0.50.9+/-0.11.4+/-0.22+/-0.22.6+/-0.33.2+/-0.329+/-0.50.9+/-0.11.4+/-0.22+/-0.22.6+/-0.33.2+/-0.330+/-0.81.0+/-0.11.4+/-0.22+/-0.22.6+/-0.33.2+/-0.332+/-0.81.0+/-0.21.4+/-0.22+/-0.22.6+/-0.33.5+/-0.334+/-0.81.0+/-0.21.4+/-0.22+/-0.22.6+/-0.33.5+/-0.336+/-0.81.0+/-0.21.4+/-0.22+/-0.22.8+/-0.33.5+/-0.338+/-0.81.0+/-0.21.4+/-0.22+/-0.22.8+/-0.33.5+/-0.340+/-1.01.0+/-0.21.6+/-0.22.3+/-0.23.0+/-0.33.8+/-0.442+/-1.01.2+/-0.21.6+/-0.22.3+/-0.23.0+/-0.33.8+/-0.444+/-1.01.2+/-0.21.6+/-0.22.5+/-0.33.0+/-0.33.8+/-0.446+/-1.01.2+/-0.21.6+/-0.22.5+/-0.33.2+/-0.34+/-0.448+/-1.01.2+/-0.21.6+/-0.22.5+/-0.33.2+/-0.34+/-0.450+/-1.01.4+/-0.21.8+/-0.22.5+/-0.33.5+/-0.34.2+/-0.452+/-1.01.4+/-0.21.8+/-0.22.5+/-0.33.5+/-0.34.2+/-0.454+/-1.01.4+/-0.21.8+/-0.22.5+/-0.33.5+/-0.34.2+/-0.456+/-1.01.4+/-0.21.8+/-0.22.5+/-0.33.5+/-0.34.5+/-0.558+/-1.01.4+/-0.21.8+/-0.22.5+/-0.33.5+/-0.34.5+/-0.560+/-1.51.6+/-0.22.2+/-0.23.2+/-0.44.2+/-0.55.3+/-0.562+/-1.51.6+/-0.22.2+/-0.23.2+/-0.44.2+/-0.55.3+/-0.564+/-1.51.6+/-0.22.2+/-0.23.2+/-0.44.2+/-0.55.3+/-0.566+/-1.51.6+/-0.22.2+/-0.23.2+/-0.44.2+/-0.55.3+/-0.568+/-1.51.6+/-0.22.2+/-0.23.2+/-0.44.2+/-0.55.3+/-0.570+/-1.51.6+/-0.22.2+/-0.23.2+/-0.44.2+/-0.55.3+/-0.572+/-1.51.6+/-0.22.2+/-0.23.2+/-0.44.2+/-0.55.3+/-0.574+/-1.51.6+/-0.22.2+/-0.23.2+/-0.44.2+/-0.55.3+/-0.576+/-1.51.6+/-0.22.2+/-0.23.2+/-0.44.2+/-0.55.3+/-0.578+/-1.61.6+/-0.22.2+/-0.23.2+/-0.44.2+/-0.55.3+/-0.580+/-1.81.8+/-0.22.5+/-0.33.5+/-0.45+/-0.66.3+/-0.582+/-1.81.8+/-0.22.5+/-0.33.5+/-0.45+/-0.66.3+/-0.584+/-1.81.8+/-0.22.5+/-0.33.5+/-0.45+/-0.66.3+/-0.5(Size between DN80 and 320mm can be customized)  Product
