Tantalum Pipes & Tubes Manufacturer and Supplier in India
Home > Tantalum Products > Tantalum Pipes & Tubes
Tantalum pipes and tubes are made up of 99.95 percent minimum purity, in grades R05200 and R05400, built to ASTM B521. Tantalum resists nearly every acid at nearly every concentration and temperature, with hydrofluoric acid the one notable exception, which is why tantalum pipe is specified for the most demanding acid duty in a plant. Kalpataru Piping Solution manufactures tantalum pipe and tube in seamless and welded construction, in custom diameters and wall thicknesses to suit reaction vessels, heat exchangers and specialized process equipment. Every tantalum product order ships with a mill test certificate confirming chemical composition and dimensional accuracy before dispatch.

Frequently Asked Questions
What is the difference between R05200 and R05400 tantalum?
R05200 is electron beam or vacuum arc melted unalloyed tantalum. R05400 is made by powder metallurgy. Both are unalloyed and offer the same corrosion resistance; the difference is in grain structure and how they machine.
Is tantalum resistant to all acids?
Nearly all. Tantalum resists almost every acid at most concentrations and temperatures, with one exception: hydrofluoric acid, which does attack it.
What documentation comes with a tantalum tube order?
A mill test certificate confirming chemical composition and dimensions, with third-party inspection available on request.
Why is tantalum used in semiconductor equipment?
Tantalum’s exceptional purity and chemical resistance make it ideal for equipment that must not contaminate ultra-clean semiconductor and capacitor manufacturing processes.
What is the difference between tantalum R05252 and R05255?
Both are tungsten-alloyed tantalum grades. R05252 contains 2.5 percent tungsten for a moderate strength increase, while R05255 contains 10 percent tungsten for higher strength and hardness at some cost to ductility.
