Sapphire Tube FAQs

Q1. What is a Sapphire Tube?

A sapphire tube is a cylindrical component made from synthetic sapphire, known for its exceptional mechanical, thermal, and chemical properties. These tubes are used in various high-performance applications where durability and reliability are critical.

Q2. Can Sapphire Tubes be customized?

Yes, sapphire tubes can be customized to meet specific requirements, including different diameters, lengths, wall thicknesses, and surface finishes. Customization can also include features like flanges, holes, and specific optical coatings.

Q3. What is the difference between Sapphire Tube and Quartz Tube?

Strength and Hardness: Sapphire is harder and stronger than quartz.

Chemical Resistance: Sapphire offers better resistance to a wider range of chemicals.

Thermal Performance: Both materials have excellent thermal properties, but sapphire can withstand higher temperatures and thermal shock better.

Optical Properties: Sapphire provides better optical clarity and lower light scattering across a broader wavelength range.

I would like to know what size tubes you have available, and their pressure rating, I wish to use them as a view pressure vessel, approx 50 - 100ml volume. I would also like some additional information about the preferred method of sealing to 316L stainless steel end plates I need to manufacture. The pressure I am shooting for is approx 350BAR.

There are several methods for sealing, all of which have good and bad qualities.

• Organic sealing system such as one of our special two part of heat cured resins.
• Low temperature soldering using an activated solder
• High temperature brazing.

The sealing system choice depends on the maximum and minimum temperature, the chemicals and gasses the seal will be exposed to, and the materials to be sealed. FYI: Sapphire seals very well to Ti and Nb, OK to higher CTE metals like 17-4 and Monel, and very poorly to 300 series SS and aluminum because of the high CTE of these metals.

We believe that Sapphire will be a very good material for your aims. But for liability reasons we cannot design your system. We can seal your system by your design though, and even suggest what sealing system to use for your design.

I have a question in regards to sapphire and lasers. How does sapphire hold up against lasers. I need to cut some semi transparent film with a laser. I'm using a backlight and a machine vision system to determine where I need to cut, and then use a laser to cut. The focused laser power is less the 2 watts. Do you think sapphire would not ablate with this power of laser? I would like to use sapphire window in an instrument measuring fluorescence of a fluid in a well. The excitation light would pass through the sapphire window. How much will the sapphire fluorescence compared to fused silica or optical glasses? We are at this stage working on a prototype laser for subsea use. We need a custom made flange mounted on a clear glass. The glass diameter will be ca 30mm. I am not sure of which type of glass we need for the application. Max pressure will be 15.000psi and max temp 150 degC. Do we need to use a sapphire to get it strong enough or can we go for a glass of lower quality/price? How thick will the glass need to be to be able to handle this type of pressure and temperature? If this product are set in production a Typical order of glass will be 25-50 or 100 pieces, how will this impact on the price? We've a optical sensor which exists of 2 saphire windows in glued a Stainless steel housing. The windows and the cylindrical SS housing should be one smouth surface. No glue recesses are allowed. Can you grind and/or lappe the surfaces without loosing optical properties? Would it be possible for you to send me a price list for High pressure sight windows? I am thinking about using a sapphire lightpipe to reduce the effect ot convection currents in a degC interferometer instrument I am designing. I would need a lightpipe around 40mm across (either circular or rectangular 40mm x10mm). How long a lightpipe would be possible to have made? I would need the end faces to be parallel and polished, but slightly tilted to stop reflections affecting my instrument. As I am using polarised light in my experiment is it possible to select a crystal orientation that will not experience birefringence? I assume as the material is a single crystal that the material properties are very homogeneous. Which type of sapphire windows are preferable for mounting on combustion chamber at high pressure & temperature? We'd like to measure some effects on materials in an oven. The product itself can increase temperatures up to °C. I have no idea about the air temperature of the oven. I want to use sapphire as a window for a cooled thermal imaging camera from 3-5µm. Would Sapphire be the right choise? What is the thickness I should take, or is there a maximum diameter? Is it possible to buy just one or two pieces?
