Tempered Sight Glass Round Glass Plate, high-Temperature and high-Pressure Resistant Boiler Pipeline Glass Sight Glass Flange Valve Observation Glass (15mm, 80mm)

💖✅ MADE for industrial safety, leaving no place for hidden dangers! This tempered sight glass is specially designed for high-temperature and high-pressure environments. It is made of aviation-grade borosilicate material and undergoes a dual strengthening process of tempering and annealing to ensure its stability even under drastic temperature changes and high-pressure impacts. Whether it's the steam pipes in thermal power plants, the reaction vessels in chemical plants, or food-grade aseptic filling lines, it can provide a clear and real-time internal monitoring view, helping you efficiently identify faults and eliminate potential safety hazards.💖✅ Why choose us? - Strict quality control: Each piece of glass has passed ISO 9001 certification and undergone 100% pressure testing to eliminate defects. - Super compatibility: Supports non-standard size customization (contact customer service for solutions), compatible with American standard/European standard flanges.💖✅ Technical parameters - Material: Borosilicate tempered glass - Temperature resistance range: -50°C to +550°C - Compressive strength: 10MPa (static) / 8MPa (dynamic) - Light transmittance: ≥92% - Surface hardness: Mohs scale 6 - Water resistance :<0.5mg/cm ² Acid resistance :<0.5mg/cm ² Alkali resistance: <0.5mg/cm ² - Temperature resistance strength :>1100kg/cm ² - Hydraulic strength resistance: At normal temperature and -25, 25KG/cm ²💖✅ Applicable scenarios 🔥 Boiler room observation window | 🔧 Petrochemical pipeline | ⚡ Steam power equipment 🍺 Food and beverage processing line | 🧪 Laboratory reaction vessels | 🏭 Industrial machinery window💖✅ Warm reminder This product is tempered glass. Due to the characteristics of tempered glass, the edges and corners are relatively brittle compared to the flat surface. During handling, try to avoid hard objects touching the edges. This is not a quality issue but a physical property of all tempered glass.💖✅ Packing List Tempered sight glass sheet ×1 | Shock-absorbing pearl cotton packaging ×1

• 💖✅ Super durable It adopts high-strength tempered glass technology, can withstand extreme temperatures ranging from -50°C to 550°C, and has a pressure resistance of up to 10MPa. It is suitable for harsh environments such as high-temperature and high-pressure boilers and chemical pipelines.
• 💖✅ safety explosion-proof design The tempering and multi-layer heat treatment technology enhances the impact resistance by three times. Even if it breaks, there will be no sharp fragments, ensuring the safety of the operators.
• 💖✅ multi-size fit The diameter ranges from 20mm to 300mm, and custom thickness is supported (default 5-25mm). It is perfectly compatible with the sight glass holes of industrial equipment and can be quickly replaced without modification.
• 💖✅ Wide industrial applications Boiler monitoring, petrochemical pipelines, steam systems, food processing equipment, energy machinery - Clearly observe the internal fluid state to ensure the safety and controllability of the process.
• 💖✅ ready to use and durable The surface is polished to prevent dirt, corrosion-resistant and anti-aging, not afraid of acid and alkali environments, reduces maintenance costs, and maintains high light transmittance for a long time.
