1.5 Inch Titanium Tubing for Industrial and Fabrication Projects
Supply envelope: the seamless range spans 5 to 325 mm outside diameter, in Grade 2, Grade 5 and other grades by requirement.
Beiyu supplies 1.5 inch titanium tubing for buyers who need a specific outside diameter for fabrication, corrosion-resistant piping, heat transfer parts, bicycle-related tube projects, marine hardware and custom titanium assemblies. The term "1.5 inch titanium tubing" should be confirmed as nominal size or actual outside diameter before quotation.
Tube requirements depend on grade, wall thickness, length, construction method and final application. For heat exchanger use, ASTM B338 may be relevant. For seamless pipe, ASTM B861 may apply. For welded pipe, ASTM B862 may apply. Drawing-based projects should define the required dimensions and acceptance criteria clearly.
Grades, Standards and Tube Type
| Common grades | Grade 2 commercially pure titanium, Grade 5 / Ti-6Al-4V and project-specified titanium alloys. |
|---|---|
| Standard references | ASTM B338, ASTM B861, ASTM B862 or customer drawing depending on tube use. |
| Construction | Seamless tube, welded tube or drawing-based tube component as specified in the RFQ. |
| Surface condition | Pickled, polished, bright, cleaned or machined surface according to application. |
Size, Wall Thickness and Tolerance
RFQs should define whether 1.5 inch means actual OD, nominal pipe size or a design description. Buyers should include OD, wall thickness, length, tolerance, straightness, end condition and quantity. If the tube will be welded, bent, machined or assembled, the required surface condition and end preparation should also be stated.
For lightweight structures or bicycle-related tube projects, the grade, wall thickness tolerance, straightness and surface finish are important. For chemical or seawater service, corrosion environment, pressure, temperature and related fitting or flange standards should be included.
Common Applications
- Chemical and seawater corrosion-resistant tube assemblies
- Heat exchanger, condenser and cooling equipment components
- Marine hardware and lightweight fabricated structures
- Bicycle frame or sports equipment tube projects controlled by drawing
- Custom machined tube sleeves, spacers and structural parts
Inspection and Documentation
Buyers can request mill test certificate, EN10204 3.1 documentation, heat number traceability, chemical composition, mechanical properties and dimensional inspection. Depending on tube type and service requirement, hydrostatic testing, eddy current testing, ultrasonic testing, PMI testing or third-party inspection can be specified.
Packaging and Export Information
Titanium tubes should be protected from bending, scratches and end damage during packing. Straight tubes may be bundled with end caps and protective wrapping. Polished or thin-wall tubes may require additional separation. Labels should identify grade, standard, size, wall thickness, length and heat number when traceability is required.
RFQ Information Needed
- Confirm actual OD or nominal pipe size
- Grade, standard and seamless or welded construction
- Wall thickness, length, tolerance and end condition
- Surface finish, straightness and cleanliness requirement
- Quantity, destination and packing requirement
- Certificate, testing and inspection documentation
FAQ
Is 1.5 inch titanium tubing measured by OD or nominal pipe size?
It can mean different things in different RFQs. Buyers should confirm whether 1.5 inch refers to actual outside diameter, nominal pipe size or a drawing dimension.
Which grades are used for 1.5 inch titanium tube?
Grade 2 is commonly used for corrosion-resistant tubing. Grade 5 / Ti-6Al-4V may be specified for higher strength or lightweight structural parts.
What documents can be requested with titanium tubing?
Common documents include mill test certificate, EN10204 3.1, heat number traceability, chemical composition, mechanical properties and dimensional inspection report.

Specification detail with sources
ASME B36.10M and B36.19M pipe dimension tables are the first check for a 1.5 inch titanium enquiry: NPS 1 1/2 pipe actually measures 48.3 mm (1.900 in) outside diameter, while a true 1.5 inch tube measures 38.1 mm, a 10.2 mm difference that decides whether the order belongs on ASTM B338 tube paper or on B861 seamless or B862 welded pipe paper. Settling that single dimension first prevents the most common mismatch in inch-size titanium quotations.
Beiyu Titanium quotes both readings, 38.1 mm tube and 48.3 mm NPS 1 1/2 pipe, from the same seamless range that spans 5 to 325 mm outside diameter, in Grade 2, Grade 5 and other grades by requirement. Once the diameter question is settled, the order still needs wall thickness, length, construction route and certificate scope, and Beiyu then confirms the matching ASTM basis, B338, B861 or B862, so the paperwork agrees with the way the dimension was specified.
Specification for Grade 2 and Grade 5 titanium tube
The grades on this page are not all covered by the same standard, so the controlling standard is listed per grade rather than once for the page. That column is what fixes the acceptance requirements, so it belongs on the order line next to the grade.
| Grade | UNS designation | Werkstoff number | Controlling standard | Selected composition limits, mass percent |
|---|---|---|---|---|
| Grade 2 commercially pure titanium | R50400 | 3.7035 | ASTM B338 for seamless and welded tube for condensers and heat exchangers or ASTM B861 for seamless pipe or ASTM B862 for welded pipe, stated on the order | Unalloyed Ti, O 0.25 max, Fe 0.30 max |
| Grade 5 Ti-6Al-4V | R56400 | 3.7165 | ASTM B861 for seamless pipe or ASTM B862 for welded pipe, stated on the order | Ti-6Al-4V (Al 5.5 to 6.75, V 3.5 to 4.5) |
Minimum mechanical values are not listed here because they are set by the ordered standard for the ordered form, size range and condition. Beiyu confirms them against that standard when quoting rather than carrying them across from another product standard.

Dimensions
State outside diameter, wall thickness and length, and say whether the item is ordered as tube or as pipe, because that is what fixes the governing standard and with it the acceptance requirements.
Inspection and documentation
The inspection scope is set by the order rather than assumed. State which examinations are required, to which acceptance standard and class, and at which stage they are performed, because those four fields are what make an inspection line objectively verifiable during receiving inspection.
Acceptance criteria you can paste into your purchase order
Grade and standard: ______ (keep one: Grade 2 commercially pure titanium to ASTM B338 or ASTM B861 or ASTM B862; Grade 5 Ti-6Al-4V to ASTM B861 or ASTM B862) Form and dimensions: ______ Tolerance: ______ Condition: ______ (R / M / Y, stated on the order) Surface: ______ (state a roughness value where it is an acceptance criterion) Straightness and ovality: ______ Inspection scope: ______ (examination, acceptance standard, class and stage) Certificate: EN 10204 3.1 inspection certificate, chemistry traceable to heat number, mechanical results and inspection lot identification per the governing specification
Send the drawing or purchase specification with those fields filled in and Beiyu reviews the enquiry against the applicable standard before pricing.
