Quality Policy

A quality statement that promises commitment to excellence prevents nothing. The failures found in the supply of materials are familiar and repetitive: the certificate that specifies the heat on the item incorrectly, the grade that looks similar to the original because it does not differ on the surface, the cut length without any marking, and the requirement for an impact for the pipe which has been simply forgotten during bolting. This quality policy for a piping supplier is written as the controls against those, and it should be read alongside the MTC and EN 10204 guide.

1. Material Is Supplied Against the Governing Document

Where an enquiry carries an operator or EPC material specification, the offer and the supply are made against that document, not against the ASTM or API minimum alone. Where a project is qualified against a specific edition of a standard, that edition is stated on the order and on the certificate.

Material that is standard compliant but specification non-compliant is treated as non-conforming.

2. Traceability Is Maintained to the Item

Control	What it means in practice
Heat or cast number recorded against every item	The certificate links to the material, not to a consignment
Marking legible on delivery	Paint stencil or hard stamp where durability is required, since adhesive labels do not survive handling or outdoor storage
Transfer marking across a cut	A piece cut from a longer length carries its identification across the cut, recorded at the time
Split certification on partial supply	Handled at the point of sale, so quantity certified matches quantity shipped
Documentation accompanying the material	Certificates travel with the consignment, not separately

3. Certification

EN 10204 3.1 inspection certificates are supplied as standard. EN 10204 3.2 certificates, validated by an independent inspector or the purchaser's representative, are supplied where ordered. A 3.2 requires witnessed testing and is therefore arranged before production; it cannot be created afterwards and re-testing finished material does not reconstruct it.

Certificates are expected to show, as a minimum: heat number, specification and grade with class or type, chemical composition, mechanical properties, impact results with test temperature where impact testing applies, heat treatment condition, dimensions and quantity, non-destructive examination performed, and the standard edition.

4. Grade Identification

Positive material identification is applied where alloy grades pass through shared handling, and its limits are acknowledged rather than ignored:

PMI cannot separate grades whose difference is a mechanical property rather than chemistry. A106 Grade B and A333 Grade 6 are close enough in chemistry that only the impact report distinguishes them
PMI cannot separate Grade 91 from Grade 92 with standard portable equipment, because the difference is tungsten
Where PMI cannot discriminate, segregation and marking carry the control instead

5. Inspection

Third party inspection by a buyer's nominated agency is arranged where required, with the scope and the hold points agreed before testing begins. Inspection requirements are confirmed at order stage because they affect the release sequence at the mill and therefore the schedule.

6. Preservation and Packing

Material is packed for sea freight and for storage in Gulf conditions:

End caps and bevel protection on pipe, and hard face protection on flanges, including on ring joint grooves
Stainless, duplex, nickel and copper alloy items segregated from carbon steel handling equipment, so iron is not transferred onto a finished surface
Preservation specified for the expected storage duration and exposure, because material going onto an open laydown needs more than material going into a fabrication shop
Thread protectors where applicable

Detail is on the packing and despatch page.

7. Non-Conformance

Where material or documentation does not meet the order, it is identified, segregated and reported to the buyer rather than resolved by substitution. A technically equivalent alternative is offered as a deviation for the buyer's approval, with the difference stated; it is not supplied as a like-for-like replacement.

Equivalence between standards is treated as a deviation requiring approval. An EN grade offered against an ASTM callout differs in chemistry range, test temperature or delivery condition, and those differences are stated rather than described as equivalent.

8. What We Ask of the Buyer

Quality control is a two way requirement, and the following prevent most non-conformances before they can occur:

The governing specification, sent with the enquiry
Service conditions, where testing depends on them
The certification type required, and for a 3.2 the nominated agency
Marking requirements, including transfer marking if material will be cut
Whether the end user is an operator who will inspect on arrival
The standard edition the project is qualified against

Scope Note for Client Approval

This document is drafted as a policy statement for Oman Piping Solution to adopt. Management system certifications, accreditations and registrations are deliberately not referenced, because they have not been confirmed. Where such certifications are held, they belong on the certifications page and can be referenced here once provided.

Quality Policy FAQ

What certification is supplied as standard?

EN 10204 3.1 inspection certificates, with 3.2 certificates supplied where ordered. A 3.2 requires witnessed testing and has to be arranged before production.

How is traceability maintained when material is cut?

By transfer marking recorded at the time of the cut, so the piece carries its identification across the cut rather than losing it.

What are the stated limits of positive material identification?

It cannot separate grades that differ by a mechanical property rather than chemistry, such as A106 Grade B and A333 Grade 6, and it cannot separate Grade 91 from Grade 92 with standard portable equipment.

How is non-conforming material handled?

It is identified, segregated and reported to the buyer. An alternative is offered as a deviation with the difference stated, not supplied as a like-for-like replacement.

Is an EN grade accepted against an ASTM callout?

Only as an approved deviation. Chemistry ranges, test temperatures and delivery conditions differ, so it is not treated as a translation.

Why does inspection scope need to be agreed early?

Because it affects the release sequence at the mill, so a requirement raised after the order changes the schedule rather than just the paperwork.

Discuss Quality Requirements

Send the governing specification, the certification type and the inspection scope with the enquiry. Those three settled at the start prevent the majority of documentation non-conformances, which cause more delay on site than material defects do.
