Specification Mapping
| Product route | Typical order dimensions | Specification when required | Scope boundary |
|---|---|---|---|
| Condenser / heat-exchanger tube | OD × wall × length | ASTM B338 / ASME SB-338 | Seamless or welded tube; confirm grade, revision, condition and tests. |
| Seamless pipe | NPS × schedule or exact dimensions | ASTM B861 / ASME SB-861 | Seamless pipe; define service, design code, ends and test package. |
| Welded pipe | NPS × schedule or exact dimensions | ASTM B862 / ASME SB-862 | Welded pipe; define weld route, condition, NDT and acceptance. |
| Shaped / fabricated tube | Drawing and controlled dimensions | Customer drawing or verified standard | Do not apply B861 automatically to square or rectangular tube. |
Not every grade is included or available in every product form, size, condition or specification. Confirm the exact combination in the quotation.
Engineering Inputs
A material grade or successful product test does not create a system pressure rating. The responsible designer must apply the governing code using actual dimensions, material properties at design temperature, joint factors, allowances, service conditions and system configuration.
Media, concentration, contaminants, temperature, pressure, velocity and cycling.
OD, wall, ID, NPS, schedule, tolerance, straightness, length and ends.
Seamless or welded route, bending, joining, heat treatment, cleaning and inspection.
Design code, allowable stress, joint factor, allowances and approval authority.

Process Review
The actual source, manufacturing or processing location, inspection route and document package are confirmed for each order.
Form, standard, grade, dimensions, service and documents.
Seamless, welded, source condition and processing boundary.
Cutting, ends, bending or drawing-based work as agreed.
Order-specific dimensions, visual checks, tests and reports.
Traceability, protection, packing, documents and delivery basis.

Frequently Asked Questions
Provide tube or pipe form, seamless or welded route, grade, governing specification and revision, OD and wall thickness or NPS and schedule, length, quantity, tolerance, condition, ends, testing, documents, packing and destination. Add drawings for fabricated or shaped products.
Tube is commonly ordered by outside diameter, wall thickness and length. Pipe is commonly ordered by NPS and schedule or by stated pipe dimensions. The applicable specification and actual dimensions should always be included.
ASTM B338 covers seamless and welded titanium tubes intended for condenser and heat-exchanger service; ASTM B861 covers seamless titanium pipe; ASTM B862 covers welded titanium pipe. State the required revision and supplementary requirements in the order.
Both routes can be reviewed, but availability, source, dimensions, grade, condition, testing and processing location are quotation-specific. The accepted route must be recorded before order.
It cannot be determined from the material name alone. The responsible designer must apply the governing design code using dimensions, material properties at design temperature, joint factors, allowances, service conditions and system details.
No. Applicable tests, sampling, acceptance criteria, witness points and reports depend on the product specification and purchase order. They must be agreed before quotation and order release.
Share the available product form, grade, specification, dimensions, quantity, service, testing and document requirements. A drawing is optional for the first enquiry and recommended for shaped or fabricated products.
