Tantalum Tube and Pipe

Tantalum Tube and Pipe for Acid Heat Exchangers and High-Purity Processing: ASTM B521 Seamless and Welded Options

Acid service and high-purity work call for the right material. Shaanxi Chuanghui Daye Metal Material Co., Ltd. (Chdymetal) makes Tantalum Tube and Pipe to ASTM B521 in two grades: commercially pure tantalum (UNS R05200) and the tantalum-tungsten alloy Ta-2.5%W (UNS R05252). Both seamless and welded forms come in a range of purities and sizes. Customized service is available on request. Wall thickness runs from 0.3 mm to 1.5 mm. That fits shell-and-tube heat exchangers, bayonet heaters and condensers. See the specification table below. Then send your grade, form, wall thickness, size and quantity for review.

What Are Tantalum Tubes and Pipes?

Tantalum tubes and pipes are metal tubular goods that resist corrosion. They are made from commercially pure tantalum (UNS R05200) or a tantalum-tungsten alloy (UNS R05252).

In the chemical process industry, corrosive media break equipment down fast. These tubes are built for that kind of duty. You will find them in heat exchangers and bayonet heaters. They also serve in condensers that handle hot concentrated sulfuric (H2SO4), hydrochloric (HCl) and nitric acids.

Material Properties for Heat Transfer and Acid Service

A stable pentoxide (Ta2O5) layer sits on the surface of tantalum. That layer can repair itself. Many organic and inorganic acids do not bother it. The acid you pick still matters. So do the concentration and the working temperature. Look at your service conditions first, then choose a grade.

Bending and coiling tubes is easier as well, because tantalum is ductile. That counts for a lot during heat exchanger fabrication. Walls stay thin, 0.4 mm–1.0 mm is common, and heat passes through the tube more easily that way.

This product is metal right through. Graphite and glass-lined equipment can turn brittle, and this material does not have that problem.

Be used in a wide range of industries.

Grade and Form Options

Commercially pure tantalum is a job for R05200. Grade R05252 carries 2.5% tungsten, and that tungsten raises the strength. Reach for it when the job asks for more. Tensile and yield values listed in the table shift from one grade to the next.

A tube made with no weld seam has one continuous wall. Use it when the tube has to be the same all around. For standard heat exchanger duty, welded and drawn tubes work. They are often the cheaper pick.

Pick the grade and the form of Tantalum Tube and Pipe to suit the acid in use. Temperature plays a part. So does pressure. Fabrication planning comes after that.

Applications

• Acid regeneration heat exchangers: In steel pickling lines, tantalum tubes sit inside shell-and-tube units. Agrochemical production puts them to the same use. Sulfuric acid gets re-boiled there. Bayonet heaters depend on them too. Concentrating sulfuric acid is one task. Recycling hydrochloric acid is the other.
• Pharmaceutical synthesis: Condensers and reflux systems are one place where tantalum fits. It works there. A metal surface that fights corrosion often beats glass in that role. For each process, check what purity and paperwork the job needs.
• High-purity fluid handling: In high-purity work, tantalum tubing can go into lines that carry corrosive chemicals. Keep that in mind. Surface finish and cleanliness requirements are not covered by our data. Add those details to your inquiry.

FAQ

Q: Are tantalum tubes able to withstand hydrofluoric acid (HF)?

A: No. Tantalum does not hold up well to HF or hot concentrated alkalis. Fluoride ions break down the protective oxide layer. That can lead to failure.

Q: How does a tantalum tube made without a seam compare with welded tube?

A: A tube made without a seam has no weld line at all. Welded and drawn tube usually costs less. It handles standard heat exchanger duty well too. Which one fits your job depends on pressure, temperature, and how you fabricate it. Send over your operating conditions and we will take a look. We also supply the Tantalum Tube and Pipe in custom sizes to suit your drawing.

Q: Next to graphite, how well does tantalum last through its service life?

A: Tantalum does cost more than graphite at the start, that is true. Your real spend over the full service life comes down to three things: how the unit runs, how often it gets serviced, and when parts are replaced. Base your choice on your own duty, not on the sticker price.

Q: What is the way to join a tantalum tube to a steel tubesheet?

A: Welding tantalum right onto steel is something most people stay away from. Brittle intermetallic phases can form that way. Tantalum-clad tubesheets are one common route. Mechanical tube expansion is the other. Run the design past the fabricator of your equipment.

Q: Ta-2.5%W (R05252) brings something that pure tantalum (R05200) does not have. What is it?

A: R05252 holds 2.5% tungsten. That tungsten is where the strength comes from. Grade matters here, so the tensile and yield ranges in the specification table shift with it. Check wall thickness against your design code.

Q: What standard covers this product? Can you customize them?

A: Tubes are made to ASTM B521. Various purities and sizes are available, and customized service is offered on request.
