Sour service, API, ASME read before you price
From package to work product
A standard in one document, a service note contradicting it in another. Any one can be caught. Catching all of them, every time, is the problem.

Every value traced back to the page it came from
Sour service parameters
Every valve tag, read against API, ASME and NACE.
Loonar pulls the trunnion ball, gate, check and globe scope out of the inquiry and lays it out tag by tag: bore, pressure class, end connection, body material, trim, fire-safe test and sour-service duty. NACE MR0175 sits beside API 607 and the ASME flange standard, and every value carries the page it came from. Where the datasheet says ANSI900 and the line list says ANSI600, the conflict is on the row, not buried on page 14.
Technical deviations
Seventy-one line items become twenty-three decisions.
Loonar groups the extracted values against your qualified range, so sour service is one row covering forty-one items rather than forty-one repeated checks. MR0103 against MR0175, duplex forgings you do not stock, an ANSI900 trunnion above your range: each one is a partial or full deviation with the items it affects and the register that proves it. Fugitive emissions the RFQ never mentions is flagged as missing before it becomes an assumption.

ClauseClient clauseStatusAssessment & proposed rewording
8. Liability > 8.2 Consequential Loss Supplier shall indemnify the Company for loss of production, deferred output and loss of profit arising from defective goods. Conflicting The clause exposes the supplier to production loss on a refinery train, which is uncapped and far exceeds order value. Standard terms exclude consequential and indirect loss in all cases. Assessed against Your_Company_GeneralTermsConditionsOfSale.pdf · p.6
9. Warranty > 9.1 Warranty Period 36 months from commissioning or 48 months from delivery, whichever expires later. Conflicting Standard warranty is 12 months from commissioning or 18 months from delivery. A 48-month tail on sour service valves cannot be underwritten without a re-priced spares commitment. Assessed against Your_Company_GeneralTermsConditionsOfSale.pdf · p.4
6. Delivery > 6.3 Liquidated Damages 0.5% of contract value per week of delay, capped at 15% of total contract value. Needs review The weekly rate is within tolerance but the 15% cap sits above the 5% standard position. Turnaround-driven schedules make this the clause most likely to be triggered. Assessed against Your_Company_GeneralTermsConditionsOfSale.pdf · p.5
4. Inspection > 4.2 Third Party Inspection Company or its nominated agency may witness all hold points with 5 working days notice. Aligned Witness and hold points with reasonable notice are accepted as standard on oil and gas orders and are already reflected in the ITP template. Assessed against Your_Company_GeneralTermsConditionsOfSale.pdf · p.3
11. Compliance > 11.4 Sour Service Certification All wetted components shall be certified to NACE MR0175 / ISO 15156 with mill certificates traceable to heat number. Needs review Heat-number traceability is standard, but MR0175 certification is only held on part of the offered range. This clause should be read together with the sour service deviation. ✨ Reword with AI
7. Payment > 7.1 Payment Terms Net 90 days from receipt of a correct invoice and acceptance certificate. Aligned Net 90 is within the range accepted for EPC counterparties of this size, subject to the credit limit already recorded for this client. Assessed against Your_Company_GeneralTermsConditionsOfSale.pdf · p.2
3. Bid Instructions > 3.2 Deemed Compliance Bids are deemed fully compliant unless explicit exceptions are listed on the deviation form. Aligned Deemed-compliance provisions are accepted where a genuine deviation mechanism is available, which it is on this tender. Assessed against Your_Company_GeneralTermsConditionsOfSale.pdf · p.2
The clause register
The terms read the same way as the specification.
Every clause in the operator's conditions is classified, risk rated and assessed against your standard positions, with the page behind it. Uncapped production loss, a forty-eight month warranty tail on sour-service valves, a fifteen per cent delay cap on a turnaround-driven schedule: the four clauses that carry real exposure surface above the twenty-six that are already aligned.
