INDUSTRIAL SOURCING QUESTIONS
Answers to common product, industry and procurement questions.
These answers are practical and sourcing-focused. Product suitability, compatibility and project acceptance remain subject to the relevant technical and project requirements.
General Industrial Sourcing
Include the available OEM or manufacturer reference, part number, model, quantity, delivery requirement and any datasheet, BOQ, drawing or project specification. If some information is unknown, identify it as unknown instead of guessing.
An OEM and part number can be a strong starting point. Where possible, also include the existing equipment reference, quantity and any supporting datasheet or photograph so the requirement can be checked against the available sourcing information.
Provide the original OEM, part number, installed-equipment reference and any available datasheet. A sourcing response can then focus on locating the requested reference or identifying whether an alternative needs separate technical review.
Useful documents can include datasheets, nameplate photographs, previous purchase orders, BOQ extracts, equipment lists, panel schedules, line lists and project specifications.
Yes. A consolidated RFQ can contain multiple OEMs and product categories. Keeping each line item clearly identified with its part number, quantity and supporting reference helps the sourcing team review the request efficiently.
Start with the exact installed reference and explain why an alternative is being considered. Any proposed substitute should be assessed against the relevant technical, project and compatibility requirements before acceptance.

Product Knowledge
Start with the measurement type, OEM, part number and datasheet where available. Depending on the instrument, useful details may include range, process connection, medium, line size, quantity and project specification.
Include the valve type, OEM or part number, size, pressure class or rating, material, end connection, quantity and any actuation requirement that is already known from the project or installed equipment.
Useful information can include the OEM, model or part number, pressure range, process connection, quantity and the applicable datasheet or project specification.
Provide the manufacturer or model where known, measurement technology, process medium, line size, quantity and any project datasheet or specification available.
Include the OEM or part number, temperature range, sensor type if known, process connection, quantity and the source datasheet or technical specification.
Provide the OEM and part number where available, electrical ratings, quantity, panel schedule, BOQ, drawing or project specification relevant to the requested item.
The OEM, part number, electrical rating, panel reference and project specification can help establish the requirement. Replacement items should be matched against the installed system information.
Provide the panel type, electrical requirement, OEM references where applicable, drawings, BOQ and project specification. The request should distinguish between sourcing a complete panel requirement and individual components.
Include the OEM, system or series, part number, existing architecture, quantity and any hardware schedule or project specification. Compatibility should not be assumed from a similar product name alone.
Provide the OEM, model or part number, network architecture, port or interface requirement, quantity and any project or installed-system reference.
OEM and part number are useful where available. Equipment reference, dimensions, existing component data, quantity and photographs can also help define the requirement.
Include the manufacturer, model, application, capacity and pressure requirement where known, quantity and any equipment datasheet or project specification.
Industry Knowledge
Requirements can span instrumentation, industrial valves, compressors, actuators, electrical products and industrial IT or networking. The actual sourcing scope should be driven by the project, maintenance or replacement requirement.
Petrochemical RFQs may involve flow, pressure, temperature, analysis, level, valves, control equipment and electrical products. Include the exact technical references and project specification available for each line item.
Common ORVANTEQ product areas include switchgear, control panels, circuit protection, instrumentation, industrial networking, SCADA and PLC equipment and mechanical components.
Typical product areas can include flow meters, pressure instrumentation, level sensors, liquid analyzers, industrial valves, control systems and electrical equipment.
Requirements may include sensors, control equipment, valves, bearings, couplings, switchgear, industrial networking and IoT devices. The best sourcing reference is the actual installed equipment or maintenance specification.
Project BOQs, drawings and technical specifications are particularly useful. ORVANTEQ product areas can include electrical products, cable management, industrial lighting, control equipment, networking and mechanical components.
Relevant product areas can include valves, compressors, electrical equipment, instrumentation, industrial networking and mechanical components, depending on the vessel, terminal, facility or project requirement.
Relevant product areas can include flow and pressure measurement, temperature sensors, liquid analysis, control systems, electrical products and industrial networking. Product suitability must be assessed against the actual process and project requirements.
Yes. Instrumentation, mechanical, electrical and industrial IT products can appear across multiple sectors. The specific model, material, rating and application requirement should still be determined by the relevant project or operating environment.
Yes, where available. Equipment tags, nameplates, installed OEM references and previous purchase information can materially improve identification of replacement items.
Include quantity, required delivery date, destination and any project timing constraints alongside the technical references. This allows the sourcing and commercial response to be coordinated around the actual requirement.
Have a part number, OEM reference, datasheet, BOQ or project specification?
Send the information you already have. ORVANTEQ will review the requirement and coordinate suitable sourcing options.
