Titanium Venturi Gr2 Gr7

Titanium Venturi is a precision device used for gas–liquid mixing, gas flow measurement, and vacuum generation. It operates based on the Venturi principle: when fluid passes through a narrowed throat, velocity increases and pressure decreases, creating a localized vacuum.

This vacuum effect enables gas entrainment, suction, or adsorption, making the device highly effective in chemical and process industries.

Working Principle

The Venturi consists of two tapered sections connected by a narrow throat:

Compressed gas enters through the inlet

As the cross-section narrows, velocity increases and pressure drops

A vacuum zone forms at the throat

Surrounding gas or liquid is drawn into the system

Flow stabilizes in the diffusion section, reducing turbulence and impact

A muffler or diffuser is often used to minimize airflow shock and noise.

Key Features

Superior Corrosion Resistance
Resistant to strong acids, alkalis, and oxidizing media (including chlorine environments).

Efficient Mixing & Suction
Generates stable vacuum zones for effective gas entrainment and mixing.

High Temperature Stability
Titanium performs reliably under elevated temperatures.

Long Service Life
Significantly longer lifespan compared to stainless steel in harsh conditions.

Low Maintenance
Simple structure with no moving parts reduces wear and maintenance costs.

Applications

Chemical reactors (especially chlorine and nitric acid systems)

Gas absorption and scrubbing systems

Vacuum generation and suction systems

Process gas mixing and flow measurement

Performance Advantage vs Stainless Steel

In highly corrosive environments such as hot nitric acid systems:

Stainless steel components may require replacement every ~6 months

Titanium Venturi (Gr2/Gr7) can operate continuously for 5–10 years

This significantly reduces lifecycle cost and downtime, despite higher initial investment.

Summary

Titanium Venturi combines efficient fluid dynamics performance with exceptional corrosion resistance, making it an ideal solution for demanding chemical processing environments, particularly those involving chlorine and strong oxidizing acids.
