Product Description

Gold Coated Quartz Tube Feature

Quartz Tube With Gold Reflective Layer, Fused Silica Gold Plated Pipe, Infrared Reflection Tube for Heating and Thermal Equipment

Gold Plated Quartz Heating Tube

Gold coated quartz tubes adopt high-quality quartz substrate with inner gold film coating. The gold layer reflects infrared rays efficiently to boost heating efficiency. Widely used for infrared heating and thermal preservation equipment. Tube diameter, length and coating coverage can be customized.

Half Gold Coated Quartz Tube

RFQ1: What is the function of the gold coating inside the quartz tube?

Answer: The gold film reflects infrared radiation to concentrate heat and improve thermal efficiency.

RFQ2: Can the gold coating be applied partially instead of full length?

Answer: Yes, partial gold coating is available according to your technical requirements.
