Design Features

Silicon nitride ceramic tubing, also known as high-temperature insulating ceramic protective tubing, exhibits several key design features and material advantages that enable it to perform exceptionally well under extreme conditions:

Structural Design

These fittings include two flanges with multiple mounting holes, facilitating installation into larger piping systems. This multi-point mounting 

design ensures stability and safety under high pressure or high temperature operating conditions.

High-Performance Materials

The silicon nitride ceramic used to manufacture these fittings possesses excellent heat resistance, abrasion resistance, and chemical 

corrosion resistance, making it suitable for manufacturing industrial fittings for extreme conditions. The low coefficient of thermal expansion 

(3.1 × 10⁻⁶/℃) and high thermal conductivity (15-20 W/(m·K)) of silicon nitride help maintain the structural integrity of the fittings during 

frequent thermal cycling.

Abrasion and Impact Resistance

With a Vickers hardness up to 1500 HV and a compressive strength up to 2500 MPa, silicon nitride provides excellent abrasion and impact 

resistance, enabling the fittings to withstand wear and mechanical stresses encountered during operation.

Application areas

Silicon nitride ceramic fittings have demonstrated outstanding performance in numerous industrial applications:

Chemical Processing

In the chemical industry, these pipe fittings are used to transport highly corrosive chemicals. Their chemical resistance and high-temperature 

resistance ensure reliability and safety when handling acids, alkalis, and other corrosive substances.

Oil Refining

In oil and gas refining processes, these pipe fittings are used in high-temperature and high-pressure environments to provide necessary 

insulation and protection against material degradation and system failure.

Advanced Materials Manufacturing

In high-temperature materials processing and advanced manufacturing industries, silicon nitride pipe fittings are used to protect critical 

components, such as in high-temperature furnaces and reactors, ensuring process stability and efficiency.

Silicon nitride ceramic fittings offer reliable solutions in high-temperature, high-pressure, and chemically corrosive environments thanks to 

their superior design and high-performance material properties. Optimized design and manufacturing ensure they maintain performance and 

stability in the most demanding industrial applications, thereby improving the safety and efficiency of the entire system. Through their 

durability and functionality, silicon nitride ceramic fittings have become indispensable components in chemical processing, petroleum 

refining, and advanced materials manufacturing.
