Introduction

Fused quartz tubes are essential components in a wide range of industrial, scientific, and manufacturing applications due to their high purity, exceptional thermal resistance, and optical clarity. Understanding the different sizes and dimensions available is key to choosing the right quartz tubing for your project. In this article, we provide a detailed overview of standard and custom quartz tube sizes, usage scenarios, and expert manufacturing solutions from Jiurui Quartz Products Co., Ltd..

What Is Fused Quartz?

Fused quartz is a type of amorphous silica glass made by melting high-purity silica. It is known for:

• High thermal stability (withstands temperatures above 1000°C)
• Superior chemical resistance to acids and alkalis
• Excellent optical properties across UV, visible, and IR ranges
• Low thermal expansion, minimizing thermal shock risk

Standard Sizes of Fused Quartz Tubes

Quartz tubes are available in a variety of standard dimensions that suit most laboratory and industrial applications. These sizes are usually defined by outer diameter (OD), inner diameter (ID), and wall thickness.

1. Standard Outer Diameters (OD)

• 1 mm
• 3 mm
• 5 mm
• 8 mm
• 10 mm
• 12.7 mm (1/2″)
• 19 mm (3/4″)
• 25.4 mm (1″)
• 38 mm
• 50 mm
• 60 mm
• 100 mm
• 150 mm

2. Standard Wall Thicknesses

• 0.5 mm
• 1 mm
• 1.5 mm
• 2 mm
• 3 mm
• 5 mm (for high-pressure applications)

3. Length Options

• Standard length: 1000 mm (1 meter)
• Available up to 2000 mm or more depending on OD
• Cut-to-length services available on request

Custom Quartz Tube Options

Jiurui Quartz offers customized fused quartz tubing solutions for OEM and ODM clients worldwide. Whether you need extra-thick walls, micro-sized capillary tubes, or oversized diameters, we can manufacture to specification.

Custom Capabilities Include:

• OD range from 0.5 mm to 400 mm
• Wall thickness from 0.1 mm to 15 mm
• Length up to 3000 mm
• Ends open, closed, fire-polished, or ground
• Custom flanged ends and threaded joints

Factors to Consider When Selecting Quartz Tube Sizes

Choosing the right fused quartz tube size depends on multiple application-specific parameters:

• Operating temperature and environment
• Required mechanical strength (thicker walls for pressure)
• Optical properties (JGS1 for high UV transparency, JGS3 for IR)
• Fluid or gas volume passing through the tube
• Space constraints within the equipment

Applications of Fused Quartz Tubes

Quartz tubes are indispensable in various industries due to their chemical purity and thermal resistance. Typical applications include:

1. Semiconductor and Photovoltaic

• Diffusion and CVD furnace tubes
• Wafer processing and thermal chambers

2. Scientific Research and Laboratories

• High-temperature reaction chambers
• UV/IR spectroscopy and analytical instruments

3. Industrial Heating

• Quartz heater protection tubes
• Infrared heating systems

4. Chemical and Pharmaceutical

• Corrosion-resistant containers for aggressive chemicals
• Gas sampling lines and viewports
