| Relevant Industry Experience | 20% | At least 5 years of documented experience with the same pipe process, such as extrusion, spiral welding, longitudinal welding, coating, or end finishing. | Project references, machine model history, process flow diagrams, sample production records, and references from comparable applications. | Incorrect machine configuration, unstable production results, longer commissioning time, and higher modification costs. | High |
| Technical Capability | 18% | Supplier can define capacity, pipe diameter range, wall-thickness range, material compatibility, line speed, heating method, control system, and expected output based on measurable process data. | Technical proposal, equipment layout, utility list, capacity calculation, process parameters, tolerances, and acceptance-test procedure. | Under-sized equipment, excessive scrap, low actual output, or inability to process the specified materials. | High |
| Quality Management System | 12% | A documented quality system aligned with ISO 9001 principles, including incoming inspection, process control, final inspection, nonconformity handling, and traceability. | Current certificate issued by an accredited certification body, certificate scope, audit information, inspection plans, and sample quality records. | Inconsistent component quality, weak traceability, repeated defects, and difficult warranty resolution. | High |
| Product Safety and Regulatory Compliance | 12% | Equipment includes documented risk assessment, guarding, emergency stops, electrical protection, manuals, warning labels, and conformity documentation applicable to the installation market. | Declaration of conformity where applicable, electrical drawings, risk assessment, safety-circuit description, user manual, and test records. | Operator injury risk, import or installation delays, failed inspections, and additional compliance costs. | High |
| Factory Acceptance Testing | 10% | Formal FAT is performed before shipment using agreed test materials or equivalent materials, with documented checks for speed, dimensions, temperature control, alarms, and safety functions. | FAT protocol, test results, calibration records, production samples, inspection photographs, and signed punch-list closure. | Problems are discovered only after installation, causing commissioning delays and expensive corrective work. | High |
| Installation and Commissioning Service | 10% | Supplier provides installation guidance, commissioning support, operator training, maintenance training, and a defined response process for start-up problems. | Service scope, engineer availability, training agenda, commissioning checklist, response-time commitment, and travel arrangements. | Longer start-up period, improper operation, unstable quality, and dependence on informal technical assistance. | High |
| Spare Parts Availability | 8% | Critical parts are identified by part number, compatible specification, recommended stock level, expected service life, and typical delivery time. | Critical-spares list, exploded drawings, parts catalogue, stock policy, price validity, lead-time statement, and alternative-part details. | Unexpected production stoppages, long downtime, incompatible replacements, and high emergency freight costs. | High |
| Warranty and After-Sales Support | 5% | Warranty terms clearly define coverage, exclusions, response procedure, defect verification, replacement responsibility, and support duration. | Signed warranty clause, service-level agreement, support channels, escalation procedure, and examples of service reports. | Disputes over responsibility, slow corrective action, and unexpected repair expenses. | Medium |
| Documentation and Maintainability | 3% | Complete documentation is supplied in the agreed language, including manuals, electrical schematics, pneumatic diagrams, software backups, lubrication points, and maintenance schedules. | Sample manual, document index, drawing list, software backup policy, preventive-maintenance schedule, and training materials. | Longer troubleshooting time, unsafe maintenance, and excessive dependence on the original supplier. | Medium |
| Total Cost of Ownership | 2% | Evaluation includes purchase price, energy consumption, tooling, consumables, maintenance, spare parts, training, installation, and expected downtime—not only the initial quotation. | Five-year cost model, energy data, maintenance intervals, consumable usage, tooling prices, spare-parts prices, and service rates. | Low initial price but higher operating costs, frequent repairs, and reduced production profitability. | Standard |
