Overview
R05200 Tantalum Tube is an unalloyed tantalum tube material specified by UNS grade. It is usually selected when a drawing, material list, project document or buyer specification clearly requires R05200 tantalum in tube form.
This product is different from tantalum sheet or plate. Sheet and plate are selected for flat surfaces, thin layers, inserts, shields or cut pieces. Tantalum tube is checked by outside diameter, inside diameter, wall thickness, tube length, end condition, straightness, tube route and final tubular function.
For R05200 tantalum tube orders, the grade note is important. Buyers often need tube sections, sleeve-type parts, tubular liners, small process tube pieces or drawing-based tantalum tube components. Clear OD, wall thickness, length and working condition help confirm whether standard tube stock or custom tube preparation is more practical.

Product Description

UNS Grade-Based Tube Supply
R05200 Tantalum Tube is usually purchased when the material grade is clearly specified. The UNS grade should be confirmed together with the buyer's drawing, standard or material list before quotation.
Tube Size Control
For tube products, size information should be more detailed than flat material. OD, ID, wall thickness, length, tolerance and end condition all affect the practical supply route and cost.
Custom Tubular Parts
R05200 tantalum tube can be checked as straight tube, cut tube sections, sleeve-type pieces or drawing-based tubular components. If holes, slots, flanges, stepped ends or special end shapes are needed, a drawing should be provided.

Clear tube size and grade details help us avoid quoting a general tantalum material when your order requires R05200 tantalum tube.
Material Fit
Grade-Specified Tube Orders
R05200 tantalum tube is suitable when the buyer's specification, drawing or material list clearly calls for this UNS grade. Any grade substitution should be confirmed before order.
Process Tube Sections
Tube form may be considered for selected process-related tubular sections. Medium, temperature, concentration and exposure condition should be reviewed before material selection.
Sleeve and Liner Parts
R05200 tantalum tube can be checked for sleeve-type parts or tubular liner pieces where OD, ID, wall thickness and end condition are important.
◆ General Note: Tantalum grade selection should be checked with actual service condition, medium, temperature, atmosphere, tube size and buyer specification.
Processing & Supply

Tube Size Checking
R05200 Tantalum Tube can be checked by OD, ID, wall thickness, length and quantity. For non-standard sizes, the practical route should be reviewed before quotation.
Cut Tube Preparation
Tube stock can be prepared into fixed-length sections, sleeve pieces or short tubular blanks. End burr, squareness and surface condition should be confirmed if the pieces are used directly.
Drawing-Based Tube Parts
For tubular components with holes, slots, steps or special end shapes, drawing review is needed. Size tolerance, machining allowance and final use should be clear.

Applications
Tantalum Tube Sections
Used as R05200 tantalum tube sections where OD, wall thickness and length need to match the buyer's specification.
Sleeve-Type Components
Used for tantalum sleeve parts where inside diameter, outside diameter and end condition should be controlled.
Tubular Liner Pieces
Used as tubular liner pieces in selected assemblies where tantalum exposure and tube geometry are required.
Process-Related Tubes
Used for selected process-related tube parts where medium, temperature and service condition should be checked.
Custom Tube Blanks
Used as hollow tantalum blanks for later cutting, facing, polishing or simple machining.
Drawing-Based Tube Parts
Used for non-standard tantalum tubular components with special length, end shape, holes, slots or surface requirement.
Packing & Delivery
Tube End Protection
Tube ends should be protected according to wall thickness, end condition and whether the tube section is used directly.
Surface Wrapping
Cleaned or polished tantalum tubes can be wrapped or separated when surface marks need to be reduced.
Size-Based Packing
Long tubes, short sleeve pieces and drawing-based tube parts may need different packing methods according to length, wall thickness and surface condition.

FAQ
Q1: What is R05200 Tantalum Tube?
A: R05200 Tantalum Tube is an unalloyed tantalum tube material specified by UNS grade. It is usually ordered when a drawing or project specification clearly requires R05200 tantalum.
Q2: What information is needed for quotation?
A: Please send grade note, OD, ID or wall thickness, length, quantity, surface condition, end requirement and working condition. A drawing is recommended for custom tube parts.
Q3: Can R05200 tantalum tube be supplied as cut sections?
A: Yes, fixed-length cut tube sections can be checked according to OD, wall thickness, length and quantity. End condition should be confirmed if the sections are used directly.
Q4: Can you check seamless or welded tantalum tube?
A: Seamless or welded tube route can be reviewed according to required size, quantity and specification. Please state clearly if one route is mandatory.
Q5: What is the difference between R05200 and general tantalum tube?
A: R05200 is a specific UNS grade. General tantalum tube is not enough when the buyer's drawing or material list requires a grade-controlled tantalum material.
Q6: Can R05200 tube be made into sleeve parts?
A: Sleeve-type parts can be checked by drawing. Please provide OD, ID, length, tolerance, end detail and surface requirement.
Q7: What surface finish can be discussed?
A: As-processed, cleaned, pickled or polished surfaces can be discussed. The suitable option depends on final use, process condition and buyer specification.
Q8: What affects delivery time?
A: Delivery time depends on grade, tube size, tube route, quantity, surface finish, cutting, end preparation and any drawing-based processing requirement.
