Grade and standard
State the material designation and governing specification.
Factory Tour · Process principles
Keep the tube specification connected to its release records.
Review seamless steel tubes as a defined product and supply scope. Grade, dimensions, delivery condition and project documentation establish the route that must be confirmed for the order.
Nuclear-industry supply experience does not establish a blanket qualification for every code, class or application. Confirm the specific scope and supporting records for the project.

Process principles
A specification-to-release route.
Confirm the responsible manufacturing and supply route before agreeing availability. Keep the delivered lot linked to the approved order requirements.
Define the tube
Put the material, governing standard and supplied condition alongside the dimensions.
Agree inspection
Define mechanical tests, NDT scope and applicable project inspection requirements.
Link the records
Connect batch identification, material records, order references and the inspection certificate.
Release and protect
Agree document approval, tube-end protection, separation and packing acceptance before release.
Verification and records
The acceptance package belongs to the supplied lot.
Dimensions and interfaces
Review the section, length, tube ends and critical mating requirements.
Tests and documents
Agree the test scope and document approval process for the stated product and application.
Traceability
Maintain the connection between lot identification, material records and release documentation.
Project review
Connect the route to your requirement.
Send the material or drawing definition, intended use and the acceptance records needed for review.
