Frequently Asked Questions (FAQ)
Q1: Is this tubing suitable for sour service (H₂S environments)?
A: While not NACE-certified by default, the TAC140 alloy has excellent base resistance. For NACE-compliant configurations, contact us.
Q2: Can we customize cut lengths or machining?
A: Yes — custom cut-to-length and end-prep services are available.
Q3: Is this product traceable by heat number or MTRs?
A: Absolutely. Full MTRs and heat traceability are provided upon request.
Q4: How does this compare to P110 or L80 pipe grades?
A: TAC140 exceeds the yield strength of both P110 and L80 and is more suitable for structural/mechanical components than casing or liner pipe.
Q5: What documentation is included with shipment?
A: MTRs, inspection reports, and compliance certificates as required by your procurement spec.
