Product DescriptionStraight Through Sight Glass | 16MPa & 500°C Resistant | Custom Sizes for Pipelines, ISO/CE CertifiedIn demanding sectors like oil refining, chemical processing, and power generation, operators face critical challenges when selecting sight glasses: Glass failure under rapid temperature shifts (>400°C) or high-pressure surges.Leakage risks from poor sealing, leading to hazardous spills or downtime.Mismatched dimensions with non-standard pipelines, requiring costly custom solutions.Frequent replacements due to corrosion, abrasion, or fogging in harsh environments. Lumistar's Solution:Our Straight Through Sight Glass delivers unmatched reliability and precision for seamless fluid monitoring: Engineered for Extreme ConditionsMaterial: High-purity borosilicate glass or quartz glass, resistant to thermal shock (-50°C to +500°C) and chemical corrosion (acids, alkalis, hydrocarbons).Pressure Integrity: Reinforced 316L stainless steel flange withstands 16MPa, tested per ASME B16.5 standards.Leak-Proof Design: Dual PTFE gaskets and precision-polished edges ensure zero leakage even under vibration. Customization & CompatibilityFlexible Sizing: Diameter 15–300mm | Thickness 6–25mm | Flange types: ANSI, DIN, JIS, GOST.Optional Features: Argon-purged chambers (anti-fog), explosion-proof versions (ATEX/IECEx), or tempered coatings for abrasive slurries. Longevity & Low MaintenanceSurface hardening technology reduces scratches, extending service life to 10+ years in coal-fired plants or offshore rigs.Easy-to-replace gasket kits minimize downtime. Certifications & ComplianceISO 9001, CE, RoHS, and API 607 fire-safe certified.100% pressure-tested with digital reports for traceability. Why Lumistar? 18+ years of expertise in industrial glass solutions.24/7 technical support with CAD design and installation guidance. ApplicationsFor monitoring filling and flow in pipelines. The sight glass enables reliable monitoring of the function and performance of individual devices as well as of entire systems.Key ConfigurationsOperating pressure: up to 160 barOperating temperature: at borosilicate glass max.280℃ for quartz glass up to 500℃Installation position:anySpecial versions:with rotor-Flap-Viewing glass lampsMaterials:all weldable materials possibleConnection options:Connection flanges according to DIN to PN 160Connection flanges according to ANSl up to 1.500 LBS welding Internal thread Technical Specifications(Other sizes can be customized according to drawings.)Operating conditions:Temperature:(dependingon glass and gasket)150°C280°CPressure:≤10/16/25/40 barMaterialsBodyGG25; GS-C 25; 1.4408GlassBorosilicate glass DIN 7080 Soda lime glass DlN 8902GasketPTFE; FKM; NBR; C4400;Silicone: EPDM: GraphiteScrewsA4-70Special materials on requestMulti system certificationHaving over 10 invention patents More than 50 utility model patentsIndustry UsersCompany ProfileLumistar Special Glass Technology Co., Ltd.Lumistar Special Glass Technology Co., Ltd. is a national high-tech enterprise mainly engaged in the research and development, design, manufacturing, and processing of various types of ultra-high pressure glass windows and safety protection equipment, including high temperature and high pressure glass, ultra-high pressure glass tubes, ultra-high pressure glass mirrors, ultra-low temperature glass, oil well ultra-high pressure glass blasting discs, sapphire glass, microcrystalline ceramic glass, pipeline mirrors, pressure vessel mirrors, high vacuum observation windows, ultra-high pressure alkali resistant mica glass mirrors, high pressure level gauge aluminum silicon glass, explosion-proof spotlights, bulletproof and explosion-proof glass, sintered mirrors, bulletproof security posts, and bulletproof transparent materials.FAQQ: Do you have a factory?A: Yes, we have a factory in Jiangsu.
