Precision Seamless Tantalum Tube for Thermowells
Precision Seamless Tantalum Tube for Thermowells
Our precision seamless tantalum tubes (Ta1) are engineered for thermowells, thermocouple protection tubes, and corrosion-resistant instrumentation systems used in highly aggressive industrial environments.
Manufactured from high-purity tantalum (≥99.95%), these tubes provide exceptional resistance to strong acids, halogens, and high-temperature process conditions, making them ideal for chemical processing plants, petrochemical facilities, and nuclear instrumentation.
The small diameter and heavy wall construction ensures both installation flexibility and superior mechanical strength, protecting sensitive sensors in reactors, pipelines, and high-pressure process vessels.
Key Features
Excellent Corrosion Resistance
Tantalum is one of the most corrosion-resistant metals available. It performs exceptionally well in environments containing:
-
Hydrochloric acid
-
Sulfuric acid
-
Nitric acid
-
Chlorine and halogens
This makes tantalum tubes ideal for extreme chemical processing environments where stainless steel and nickel alloys fail.
Extreme High-Temperature Capability
With a melting point above 2900°C, tantalum tubes can operate in extreme thermal environments and maintain stability in:
-
Vacuum furnaces
-
Inert atmospheres
-
High-temperature process equipment
Operating temperature can reach up to 2300°C in vacuum conditions.
Small Diameter Heavy Wall Construction
Our tubes are designed for demanding instrument protection applications.
Advantages include:
-
Easy installation in narrow reactor nozzles or pipelines
-
Heavy wall thickness for high pressure resistance
-
Strong protection for thermocouples and RTD sensors
-
Improved durability in turbulent flow environments
High Mechanical Strength
The thick wall design enhances resistance to:
-
Process pressure
-
Fluid vibration
-
Mechanical fatigue
Ensuring long-term stability of temperature measurement systems.
