Long Description 

This custom borosilicate 3.3 glass tubing is professionally manufactured as protective glass sleeve for PV-integrated solar street lights and outdoor road lighting lamps. Made of high-purity 3.3 borosilicate glass material, it features ultra-low thermal expansion coefficient, superior thermal stability and excellent chemical durability.

With high visible light transmittance above 91%, the glass tube guarantees efficient solar power absorption and stable LED light output. It can withstand extreme outdoor temperature from -40ºC to 450ºC, resisting thermal shock, UV radiation, rain, dust and coastal humid corrosion. No yellowing, no deformation or cracking after long-term outdoor operation.

We support full-size customization including OD, ID, wall thickness and cutting length. Various edge finishing options such as fire polishing and precise grinding are available. Widely applied in municipal road solar lamps, park lighting, highway integrated solar street light fixtures. Strict quality control ensures high precision dimension and perfect appearance for customer end assembly.

COE3.3 Clear Borosilicate Glass Tube for Aviation & Marine Signal Beacon Lamp, OD_65_mm, WT_2.3_mm

Product Introduction

This COE3.3 borosilicate glass tube is professionally produced for signal beacon lamps, including aviation obstacle lights, marine navigation beacons, wind turbine warning lamps and tower signal lights.

Adopting standard COE3.3 low expansion borosilicate material, the tube features remarkable thermal shock resistance. It can withstand extreme outdoor temperature differences between high-temperature sunshine in summer and freezing cold in winter without cracking. The glass has high mechanical strength, good wind pressure and impact resistance, suitable for long-term outdoor exposed installation.

High visible light transmittance ensures stable signal light output, without yellowing or light attenuation after years of continuous operation. The material boasts superior weather resistance, resisting rainwater, salt mist, ultraviolet radiation and industrial atmospheric corrosion.

 

Custom sizes are available with various outer diameters, wall thicknesses and cutting lengths. We can also supply frosted, amber, red, green colored borosilicate tubes for differentiated signal identification.

Core Advantages

1. Wide temperature adaptability: Works steadily from -40ºC to 500ºC, anti-crack under drastic temperature change
2. Strong weather resistance: Anti-salt spray, anti-UV, anti-aging for outdoor long-term use
3. High mechanical strength: Wind-resistant, impact-proof for tower, marine and aviation scenarios
4. High light transmittance: Guarantee bright and clear signal warning effect
5. Optional colored tubing: Red, amber, green, frosted for different signal classification
6. Customizable dimensions: OD, wall thickness and fixed cutting length as customer drawings

Application Scope

• Aviation obstacle warning beacon lamps on high-rise buildings, communication towers
• Marine navigation signal lights, ship deck beacon lamps
• Wind turbine tower safety warning lights
• Bridge, viaduct, highway signal indicator lamps
• Industrial equipment warning signal beacons
