ASTM A213 T22
ASTM A213 T22 Tube Supplier
Build a T22 tube package around the approved thermal-circuit schedule. Identify straight or formed delivery, OD, wall convention, treatment, end condition and inspection hold points before price comparison. Where forming is required, specify who accepts the tube after that operation as well as at mill release.
T22 is a grade-specific A213 tube requirement. It does not make the whole A213 family T22, and it does not establish pressure-system design, welding suitability or operating limits without project review.
Supply boundary
Close the supply boundary before ordering T22
A T22 package can mean straight lengths delivered to a fabricator, or finished formed items delivered to site. Those are different scopes with different acceptance stages, and the difference has to be settled before offers are compared.
| Decision | Why it matters here | Before you enquire |
|---|---|---|
| Straight tube supplied to a fabricator | The receiving fabricator owns later operations unless included. | Define incoming acceptance and preserve heat identity. |
| Formed tube included | Bending or other processing adds a second acceptance stage. | Supply the formed drawing and post-process criteria. |
| Grade upgrade suggested | A different designation can change fabrication and code requirements. | Review the full exception; do not approve by nominal alloy content. |

Return to alloy-tube selection
Use the material-family view when the project has not yet fixed the thermal-service grade.
Coordinate ASTM requirements across forms
Keep the tube specification distinct from connected pipe, plate or fitting specifications.

ASTM A213 T22 Tube Specification — enquiry builder
Capture the decisions below, prepare a review summary and copy it to the tube RFQ. Review T22 identity and condition at the delivered stage, including any forming. Require written approval for grade changes, code-designation changes and omitted inspection points.
Acceptance basis
Put the acceptance basis on the order
T22 is a grade-specific A213 tube requirement. It does not make the whole A213 family T22, and it does not establish pressure-system design, welding suitability or operating limits without project review.
| Specification decision | Applicability and limit | Evidence to request | RFQ action |
|---|---|---|---|
| T22 identity | The exact grade must appear with the product standard. | Heat certificate and order-conformity declaration. | State T22 and the ordered edition. |
| Delivered processing stage | Straight and formed products carry different scope. | Agreed drawing, forming record and final inspection plan. | Identify responsibility for post-forming acceptance. |
| Wall and dimensions | The wall convention must survive the quotation process. | Size schedule with minimum/average basis and agreed limits. | Write the basis for every tube item. |
| Examinations and hold points | The project can require records beyond the base material certificate. | Accepted inspection plan identifying witness and release points. | List required documents and release authority. |
No chemistry limit, mechanical-property value, allowable stress or operating limit is published on this page. Every figure used in a live enquiry must come from the ASTM A213/A213M edition the contract invokes, the governing code or your own equipment specification.
Documentation
Documents that support an A213 T22 tube order
Create a record index for the T22 package: each tube item should resolve to its heat, treatment, dimensional results and any processing records included in supply. Review missing records before the shipment is released.
| Control | What to examine | When and limits | Next action |
|---|---|---|---|
| T22 identity | Heat certificate and order-conformity declaration. | Before material acceptance; confirm feasibility and cost at quotation. | State T22 and the ordered edition. |
| Delivered processing stage | Agreed drawing, forming record and final inspection plan. | Before material acceptance; confirm feasibility and cost at quotation. | Identify responsibility for post-forming acceptance. |
| Wall and dimensions | Size schedule with minimum/average basis and agreed limits. | Before material acceptance; confirm feasibility and cost at quotation. | Write the basis for every tube item. |
| Heat and item identity | Mill test certificate linked to heat markings and packing list. | Before release and again on receipt; a sample certificate is not evidence for the shipped heat. | Request traceability through cutting, bundling and delivery. |
Duty and drawing
Follow the operating duty to the right specification
The drawing and service envelope govern acceptance. These paths address different purchasing decisions; an application label does not approve a material.
Power-generation procurement
Organise the package by circuit and inspection release rather than a single plant-wide grade assumption.
Boiler tube schedules
Match each item’s grade, wall convention and preparation to the approved boiler drawing.
Process thermal equipment
Identify exchanger or heater duty and project-specific inspection requirements.
GCC markets
Plan the GCC destination around the T22 supply
Use the destination to close the quotation scope, then confirm feasibility and commercial terms in writing. Country flags identify the destination; quotation must confirm the supply route, origin and availability for this order.
Preserve circuit-item traceability and formed-piece protection on the destination schedule. Identify the emirate, fabricator or site address and unloading restrictions; distinguish a domestic handover from an import leg.
Preserve circuit-item traceability and formed-piece protection on the destination schedule. Name the consignee, importer and final site; ask who confirms product classification and border documentation before dispatch.
Preserve circuit-item traceability and formed-piece protection on the destination schedule. State the nominated receiving point and project document approver; align certificate review with the required arrival window.
Preserve circuit-item traceability and formed-piece protection on the destination schedule. Specify the actual port, border point or inland site requested; separate the entry leg from onward transport and unloading.
Preserve circuit-item traceability and formed-piece protection on the destination schedule. Identify the contractor or fabrication yard receiving the tubes; agree import-document responsibility and the named delivery place.
Preserve circuit-item traceability and formed-piece protection on the destination schedule. Confirm whether the order is for local consumption or onward shipment; name the consignee and agree who handles each transport leg.
Commercial
Compare offers on the same delivered scope
Ask for separate scope and price lines for straight supply, forming, end preparation, extra examination and witnessing. Confirm packing dimensions and handling responsibilities for formed pieces before transport is quoted.
Ask for the offered mill and origin, tube schedule, quantity basis, processing scope, packing, commercial validity and exclusions. State the Incoterm with its named place and edition, who unloads, and the requested delivery window. Price, availability, production allocation, transport feasibility and dates require written confirmation — this page does not publish a price, and every figure remains price on request.
Coordinate an export enquiry — align tube identification, bundle protection and transport documents with the named delivery place before dispatch.

Expert insight
Expert Insight: Can a family specification stand in for the exact T22 item?
A213 is a multi-grade tube specification, not a single thermal-circuit design. The purchase schedule must still identify grade and delivery stage.
Buyer implication: treat the approved item schedule as the basis for offer review.
Method: scope review with an editorial separation of material supply and equipment design. Applicability: A213 tube-family identification. Limit: no numerical design properties or blanket grade substitution is provided.

Acceptance controls
Make acceptance easier to demonstrate
Three controls carry most of the acceptance risk on a T22 package. Each one is settled before the purchase order, not on site.
T22 identity
Heat certificate and order-conformity declaration.
State T22 and the ordered edition.
Delivered processing stage
Agreed drawing, forming record and final inspection plan.
Identify responsibility for post-forming acceptance.
Wall and dimensions
Size schedule with minimum/average basis and agreed limits.
Write the basis for every tube item.
From specification to receipt
Close each decision before releasing the order
A T22 package passes four gates. Each one has an owner, a required input and an output that can be checked — and each one can fail silently if it is left open.
| Stage and owner | Required input | Evidence or output | Risk and next action |
|---|---|---|---|
| Engineering release — Buyer’s design authority | Design team releases the T22 item and delivered-stage drawing. | Approved specification and drawing revision | Unapproved substitution can change the design basis. Close the item before proceeding. |
| Offer review — Buyer and quotation team | Buyer resolves forming, testing and witnessing inclusions. | Written technical exceptions and commercial scope | An unlisted exception can survive into the purchase order. Close the item before proceeding. |
| Material release — Mill, inspector and buyer as agreed | Inspector reconciles heat and processing records to the item schedule. | Accepted documents linked to the order items | Missing heat identity can make an otherwise correct tube unacceptable. Close the item before proceeding. |
| Receipt and reconciliation — Receiving team | Receiving team checks formed geometry, protection and identification. | Delivery record, item count and discrepancy record | Record any mismatch before the material is incorporated into work. Close the item before proceeding. |
FAQ
Questions before you place the tube order
Short answers to the points that most often delay a T22 package enquiry.
Is T22 automatically an upgrade from T11?
No. A material change requires review of the complete design, fabrication and code requirements.
Can formed tube be quoted?
Request it with an approved drawing, dimensional acceptance, treatment requirements and post-forming inspection responsibilities. Capability remains quotation-dependent.
What if the project specifies an ASME designation?
Have the supplier confirm the exact required code material designation and edition. Do not silently relabel an ASTM-only offer.
Should each size carry a wall convention?
Yes. Put minimum or average wall basis on each relevant item to avoid different interpretations.
Does mill release approve later fabrication?
It approves only the agreed material-supply scope. Later processing and equipment release need the specified separate controls.
How do I compare package prices?
Reconcile grade, condition, lengths, forming, inspection, documents, preservation and delivery scope before comparing totals.
