Why this project mattered
The bundle design required tight control over bend geometry, heat treatment, hardness, corrosion resistance, and nondestructive testing. Ameritube managed the commercial and technical supply chain and delivered a completed package ready for customer review and plant installation planning.
What was managed
| Requirement | Execution and documentation |
|---|---|
| Material | SA789 S31803 / S32205 duplex stainless tubing |
| Bending and geometry | U-bend bundles produced to the bend schedule and dimensional requirements |
| Heat treatment | Solution annealing, and electric resistance stress relief of selected U-bends and tangent lengths |
| NDE and pressure testing | Eddy current per SA-789, hydrostatic records |
| Metallurgical testing | ASTM A923 Method A and C, ferric chloride corrosion test, tensile, flaring, flattening, and hardness checks |
| Documentation | Raw and final MTRs, PMI, dimensional inspection, heat treatment records, and the assembled quality package |
The result
Fourteen bundles delivered with a complete quality package: A923 and corrosion results, PMI, dimensional, hydrostatic, and heat treatment records, ready for the customer's review and the plant's installation planning.
