The most corrosion-resistant metal used today is tantalum. It is inert to almost all organic and inorganic compounds, and has a corrosion resistance similar to that of glass. Tantalum is often used in the manufacturing of dip tubes, piping, and overhead condensers.
Tantalum should be considered wherever corrosion is a concern and long-term benefits such as reduced downtime, increased life expectancy and profitability are crucial. Tantalum heat exchangers are used in corrosive and oxidising applications, for example with concentrated sulfuric acid, nitric acid, free chlorine, or free bromine.
In fine chemicals and pharmaceutical applications, they are extensively used as vapour condensers. The Mersen Linsengericht in Germany is a centre of expertise for the design and manufacture of tantalum process equipment, such as heat exchangers, pressure vessels, columns, and custom-made components. Our 3200 m2 workshop allows us to manufacture very large pieces of tantalum equipment (up to 4.4 metres wide and up to 4.2 metres high, with a maximum weight of 20 tons).
If corrosion is a factor in your chemical process and long-term benefits of increased life expectancy, reduced downtime, and increased profitability are important, then consider Tantalum Heat Exchangers .
Shell and tube heat exchangers made of tantalum solve many of the problems posed by other materials. Tantalum is not brittle and will not crack like graphite. Solitaire Overseas Heat Exchangers are fully-welded and will not leak, unlike ceramic heat exchangers using O-rings. Also we are the biggest stockist of ST52 Grade Seamless pipes in india.
The most corrosion-resistant metal in common use today is tantalum. Tantalum is inert to practically all organic and inorganic compounds. Sulfuric and hydrochloric acid are inert to this reactive metal below 300°F. An attack up to 400°F is not significant, and Tantalum is commonly used up to 500°F. Tantalum has excellent thermal conductivity, is resistant to erosion, and forms easily. Tantalum’s high workability and weldability make it the ideal tube material for corrosion-resistant shell and tube heat exchangers.
In chemical, petrochemical and pharmaceutical applications, tantalum can be incorporated into most TEMA-type shell and tube heat exchangers and bayonet heaters. Tantalum is the only reasonable choice of construction material for a variety of processing equipment.
Tantalum’s superior corrosion resistance enables it to withstand higher temperatures and pressures. Process reaction efficiencies, plant throughput, and profitability can be greatly improved with this gain.
Tantalum Heat Exchanger Designs
For chemical, petrochemical, steel, and pharmaceutical applications, tantalum can be fabricated into most Shell and Tube Heat Exchangers of the TEMA type.
Our pressure equipment is designed and manufactured in accordance with all major international design standards and pressure vessel codes.
Tantalum heat exchangers can be designed with carbon steel, fibreglass, PTFE lined, or glass-lined carbon steel head and bonnets.
Tantalum can also be clad to form a bimetallic construction material. This is an ideal solution for high-pressure Tantalum heat exchangers and reactors.
