Though Diamond is the hardest material, but it is almost impossible to make diamond tubes and rods. So Sapphire became the best choice making durable tubes and rods. Sapphire tubes can be used in harsh environments to house sensitive sensors and protect them from pressure and mechanical abuse. Sapphire tube is the best high-pressure vessel and transportation pipeline for many high-pressure systems. The sapphire tube can withstand extreme pressure while allowing safe observation and spectral analysis of fluids and gases.
In normal situation the thinnest wall thickness of sapphire tube we can make is above 2mm. As it’s longer the thickness is request to be more than 2mm. The tube wall can be chosen to be polished(Transparent) or just as all fine ground(Cloudy), as some technical bottlenecks have not yet been broken through, our company’s technical staff can only achieve the standard of polishing and translucent when polishing the cylindrical surface. Flat surfaces on the top can be highly polished with good surface flatness.
Here we established some typical products we made for other customers before.
