Standards

Global Standards. Project-Specific Execution.

ENGIC supports engineered product supply across API, ASME, ASTM, ANSI, MSS, AWWA, EN, DIN, BS, ISO, IEC, NORSOK, DNV, JIS, GOST, KS, GB, NACE / ISO 15156, and client-specific project standards.

From valves, flanges, fittings, tubulars, structural steel, and conduits to project-critical industrial materials, we help clients align products with the correct specification, service condition, inspection requirement, documentation package, and delivery schedule.

Why standards matter

International Standards & Technical Compliance

Engineered supply aligned with global project requirements

ENGIC supports engineered product supply across a broad range of international, regional, industry-specific, and client-specific standards.

Our work is not limited to one geography, one code system, or one procurement convention. We support projects operating under American, European, British, Japanese, Russian/CIS, Korean, Chinese, offshore, marine, oil and gas, water, infrastructure, utility, industrial, and project-specific requirements.

For EPCM, energy, infrastructure, and industrial clients, standards alignment is not a formality. It affects material selection, pressure ratings, dimensional compatibility, corrosion resistance, inspection scope, certification, documentation, installation, safety, and long-term asset integrity.

ENGIC helps clients source and coordinate products according to the applicable project specification, service conditions, inspection requirements, regulatory expectations, and delivery schedule.

Standards we support

Recognised international and regional standards.

ENGIC can support product supply, technical clarification, and documentation alignment across the following standard families.

Sour Service, Corrosion & Material Selection

NACE MR0175 / ISO 15156 is used for materials selection in oil and gas production environments where sulfide stress cracking and H₂S-related cracking mechanisms must be considered. TWI notes that ISO 15156 is the relevant standard family for exploration and production sour service, while NACE MR0103 is used for refinery applications.

What standards alignment means in practice

Standards compliance is not just an acronym beside a product description.

For ENGIC, standards alignment may involve:

→Reviewing the applicable project specification
→Matching the product category to the correct standard family
→Confirming material grade and pressure class
→Checking dimensional compatibility
→Reviewing temperature and service conditions
→Considering sour service, corrosion, or low-temperature requirements
→Confirming end connections, face types, coatings, linings, and finishes
→Coordinating required inspection and testing
→Managing certification and documentation requirements
→Supporting manufacturer clarification where required
→Coordinating delivery according to project schedule

Product categories covered

ENGIC applies multi-standard sourcing and documentation support across:

Engineered valves
Valve actuators
Pipe fittings
Piping flanges
OCTG
Energy tubulars
Standard tubulars
Structural steel
Electrical conduits
Project-critical industrial materials
Custom and special supply packages

Documentation & certification support

Depending on the product, project, and applicable standard, ENGIC can support documentation requirements such as:

→Material Test Certificates
→EN 10204 3.1 / 3.2 inspection certificates
→Certificates of Conformity
→Manufacturer data books
→Inspection and test plans
→Welding documentation
→NDE / NDT reports
→Hydrotest reports
→Pressure test certificates
→PMI reports
→Coating and lining reports
→Dimensional inspection reports
→Heat treatment records
→Traceability documents
→Packing lists and shipping documents
→Project-specific vendor documentation

Inspection & testing support

ENGIC can coordinate inspection and testing requirements according to project needs, including:

→Visual inspection
→Dimensional inspection
→Hydrostatic testing
→Pneumatic testing where applicable
→Non-destructive examination
→Positive Material Identification
→Hardness testing
→Impact testing
→Coating inspection
→Witness inspection
→Third-party inspection coordination
→Final documentation review

Multi-standard supply philosophy

One project. Multiple standards. One accountable supply partner.

Modern projects rarely operate under a single standard. A single engineered supply package may include API valves, ASME flanges, ASTM materials, EN documentation, NACE sour service requirements, NORSOK offshore requirements, IEC electrical requirements, and client-specific project specifications.

ENGIC helps clients manage that complexity.

Our role is to support technically aligned sourcing, supplier coordination, documentation control, inspection readiness, and delivery follow-up across multiple standards and product categories.

We do not treat standards as marketing labels. We treat them as project requirements that must be understood, coordinated, documented, and delivered correctly.

Standards disclaimer

Product availability, sizes, pressure classes, materials, coatings, linings, testing, certifications, documentation, country approvals, and delivery schedules are subject to the applicable project specification, manufacturer capability, regulatory requirements, inspection scope, and commercial confirmation.

ENGIC does not claim automatic compliance for every product in every jurisdiction. Compliance must be confirmed against the specific project specification, product type, manufacturer, certification package, and end-use application.
