Traceability and condition
Grade, size, wall thickness and heat identity are checked against the MTC and packing list. Ends, threads, coupling protection, bundle wrap and markings are inspected before lifting.

Redacted API 5CT K55 MTC and order evidence
Inspect a real API 5CT K55 document after customer and factory identifiers have been removed, together with representative dimensional-inspection and lifting/loading evidence. The sample shows the document fields; every new order receives its own heat traceability, test results and final MTC.

API 5CT K55 MTC sample after redaction
The visible fields let a buyer inspect the product and test logic without exposing unrelated customer, factory or certificate identifiers.
Visible technical fields
- Product and standardAPI 5CT casing, hot-rolled seamless, PSL1
- Dimensions9-5/8 in OD · 8.94 mm wall · BC thread
- GradeK55
- Tensile results690 MPa tensile · 410–415 MPa yield · 29–30% elongation
- Body and end inspectionPipe-body UT OK · pipe-end UT OK · visual and drift OK
- Pressure test22 MPa hydrostatic test for 10 s: OK
Document boundary: This is a redacted mill MTC sample, not a third-party inspection report and not a certificate for a future order. Customer-specific and project-specific documents are issued after final inspection and commercial confirmation.
Inspection process
What the evidence controls demonstrate
Representative photographs show the control point; they are not presented as a named customer project or proof of every production lot.
Handling and documentation
Lifting method, bundle separation, end protection and loading arrangement are checked. Photographs and shipping documents are retained for the order record, with customer-specific data kept outside public pages.
Redaction standard
What is removed from the public sample
Company and customer data
Customer name, manufacturer name and logo, address, postcode, contact data, signature and red seal are removed.
Identifiers that can link an order
Certificate number and heat/lot identifiers are concealed in the public copy. These remain present in the controlled original and order file.
Technical fields remain
Standard, product form, grade, dimensions, thread, PSL, tensile values, UT results and hydrostatic-test result remain visible for buyer evaluation.
Inspection planning
Third-party inspection and order documents
The MTC sample does not replace a project ITP or third-party release certificate.
| Document / activity | Order basis | Evidence note |
|---|---|---|
| Mill MTC | Grade, dimensions, heat number, chemical and mechanical results | Standard supply document; public preview is redacted |
| Non-destructive testing | UT, RT, PT, eddy current or other method as agreed | Method, standard, coverage and acceptance are written in the order |
| Hydrostatic test | Pressure, hold time and acceptance per specification | Order-specific result recorded on the final document |
| Dimensional and visual | OD, wall, length, drift, thread and surface requirements | Inspection record and loading photos retained |
| Third-party inspection | SGS, BV, TÜV or nominated inspector when specified | Separate arrangement; not implied by the mill MTC |
Send the grade, dimensions and inspection scope
HONGFENG will confirm the applicable MTC, NDT, third-party inspection and loading-record requirements for the actual order.
FAQ
MTC and inspection evidence questions
Is this API 5CT K55 MTC a real document?
The page uses a public redacted copy of a supplied API 5CT K55 MTC. Customer, manufacturer, certificate-number, heat/lot, address, stamp and signature identifiers are concealed; the product specification and technical results remain visible for evaluation.
Are the MTC results guaranteed for a future order?
No. The values describe the sample document shown. A new order receives its own grade, dimensions, heat numbers, test results and certificate; the signed specification, contract and final MTC govern acceptance.
Does this page prove third-party inspection?
No. The displayed document is a mill material test certificate. SGS, BV, TÜV or another nominated third-party inspection is arranged separately when specified and is not implied by this sample.
Can the full unredacted MTC be supplied?
The unredacted production document is released for the actual contract after commercial confirmation. A redacted sample is supplied first for buyer review without exposing unrelated customer, factory or certificate identifiers.
