These standards define how equipment is designed, manufactured, tested and documented. They are references for the items we supply, not certifications held by COTI.
APIAmerican Petroleum InstituteUS association that publishes the main oil & gas equipment standards, e.g. API 5CT (casing and tubing), API 5L (line pipe), API 6A (wellheads), API 6D (pipeline valves) and API 610 (pumps).
ASMEAmerican Society of Mechanical EngineersStandards for pressure equipment and piping: Boiler & Pressure Vessel Code, B31.3 (process piping), B16.5 and B16.9 (flanges and fittings).
ASTMASTM International (American Society for Testing and Materials)Specifications for materials and test methods, e.g. ASTM A106 (carbon steel pipe) and A105 (forged flanges), which define chemistry and mechanical properties.
ISOInternational Organization for StandardizationInternational standards body based in Geneva, e.g. ISO 9001 (quality management) and ISO 15156 (materials for H2S service).
EN 10204European standard for inspection documentsDefines the types of inspection documents for metallic products. A type 3.1 certificate gives actual test results, validated by the manufacturer’s independent inspection department.
IECInternational Electrotechnical CommissionInternational standards for electrical and electronic equipment, e.g. IEC 60079 (explosive atmospheres) and IEC 61131 (programmable controllers).
ATEXATmosphères EXplosibles (EU Directive 2014/34/EU)European regulation for equipment used in potentially explosive atmospheres (gas or dust). ATEX-marked equipment may be placed on the EU market for these zones.
IECExIEC System for Certification to Standards relating to Equipment for use in Explosive AtmospheresInternational certification scheme for Ex equipment, based on IEC 60079, recognised in many countries outside the EU.
NACENational Association of Corrosion Engineers (now AMPP)Corrosion-control standards; NACE MR0175 / ISO 15156 sets material requirements for equipment exposed to H2S (sour service). NACE merged into AMPP in 2021.
ANSIAmerican National Standards InstituteCoordinates and approves US national standards. The term “ANSI class” (150, 300, 600…) refers to flange and valve pressure ratings per ASME B16.5.

Coordinated from its Montréal head office, with an office and associate representative in Oran, COTI supports clients across five regions.
Our Southern Africa office covers Mozambique, Malawi, including the mining sector, Kenya and Zambia. An opening is planned in West Africa. Requests from the UAE and Oman are handled remotely and forwarded to Canada.
Our petroleum-specialist engineering office draws on the international expertise of Sallah El-Nagar, backed by more than 40 years of experience, to address your technical challenges. Technical issue, operating emergency, equipment requirement or request for advice: explain your situation and we help you work towards a suitable solution, from the first discussion through to implementation follow-up.
The field expertise of Lakhdar Saidani, backed by 27 years in oil and gas drilling, strengthens our support.
The expertise of Abdullah S Al Sharji, with 40 years of experience, strengthens our support in infrastructure and the coordination of major project portfolios. Anas Hussein contributes expertise in business development, sourcing and regional logistics, while Rezak GHELLAB coordinates international partnerships and commercial exchanges from Canada.
Share your situation, operating constraints, urgent requirement or technical question. We clarify your expectations and the information needed.

We review available specifications, part numbers, drawings and data to clarify the scope, compatibility and matters requiring verification.

We help you examine technical options, replacement solutions and maintenance constraints, within the agreed advisory scope.

We coordinate the search for specialised manufacturers and suppliers, collect proposals, and request origin and conformity documentation.

We compare proposals with your requirements: technical data, lead times, cost, traceability and available documents. Any order or intervention remains subject to your approval.

Sourcing, inspection, shipping, delivery or coordination of interventions: we follow the agreed actions and relevant parties within the agreed allocation of responsibilities.

We follow up on documents, any outstanding issues and exchanges after delivery or intervention. Your feedback helps clarify maintenance requirements and next steps.

Every request has its own constraints. Our role is to help you move forward with a clear technical approach, rigorous coordination and support tailored to your needs.
COTI relies on a Senior Petroleum Engineer and a team specialised in this field. Our Technical Advisor has more than 40 years of international experience in oil & gas, energy, mining and renewables. He supports technical qualification, OEM/API interface and the integrity review of critical parts.

COTI is a Canadian company that sources industrial equipment, spare parts, MRO materials and technical services for oil & gas, energy, hydrogen, mining and industrial projects, and coordinates inspection, documentation and logistics up to delivery.
COTI works with clients worldwide, in the Americas, the Middle East, Africa, Europe and Asia. Each request is checked against the applicable export, sanctions and customs rules.
Yes. From a nameplate photo, an old part number or a drawing, COTI identifies the item, searches cross-references and contacts stockholders, the original manufacturer and approved equivalents.
COTI supplies OEM parts whenever they are available. When they are not, technically equivalent alternatives can be proposed with their documentation, always subject to the client’s approval.
Send us your RFQ, part numbers, nameplate photos or specifications. We reply with a structured proposal.
