TANTALUM FABRICATED PRODUCTS FOR THE PHARMACEUTICAL INDUSTRY

Tantalum has many applications in pharmaceutical plants. H.C. Starck’s tantalum products are preferred because they resist corrosion, preserve product purity and offer the versatility of allowing the customer to use the same processing equipment for many applications.

Due to its much longer service life and maintenance-free durability, tantalum has proven to be your most cost-effective solution for corrosion protection in pharmaceutical and chemical processing applications.

Tantalum is a highly corrosion-resistant metal that is virtually inert to acid attack

Reactive metals like tantalum outperform other materials, drastically reduce downtime, and add years of service life to process-exposed equipment.

H.C. Starck's high purity NRC® tantalum a lasting solution in severe environments:

  • Excellent corrosion resistance
  • High strength and stability at elevated temperatures
  • High ductility and toughness
  • Superior thermal conductivity

Tantalum has a wide range of benefits:

Chemical Resistance

  • Virtually inert to chemical attack
  • Operates in the broadest range of harsh oxidizing and reducing environments
  • Requires only a thin wall of material for tubes and vessels compared to other materials

Cost Benefits

  • More cost-effective than other materials such as impregnated graphite and nickel-based alloys
  • Extends equipment life
  • Eliminates production downtime

Regulatory Requirements

  • Avoid heavy metals contamination
  • Faster validated clean-out between batches

Higher Heat Transfer Coefficients

  • 2.5 x higher heat transfer than titanium
  • Tantalum heat exchangers require 35%-45% less surface area, allowing a smaller footprint
