What Is The Market Share of "refurbished" Second-hand Rotary Drilling RIGS? How To Identify

In the second-hand rotary drilling rig trading market, "refurbished machines" have become a means for some unscrupulous merchants to make profits because they can cover up equipment defects and raise prices. At present, there is no authoritative statistics on the market share of refurbished machines in the industry. However, based on first-hand procurement data, it is estimated that the proportion of refurbished machines in small and medium-sized trading platforms may reach 15% to 25%. Identifying refurbished machines is a key link to avoid procurement losses.

1. Appearance coating inspection: The original factory coating has uniform color and consistent texture. Refurbished machines often have local touchup marks. The thickness can be detected with a paint film meter. If the thickness difference in the same area exceeds 50μm, it is very likely to be refurbished. At the same time, pay attention to small components such as screws and joints. Refurbished machines often have coating color mismatches due to component replacement.

2. Verification of core component numbers: Core components such as engines and hydraulic pumps all have original factory numbers. You can check the production year and installation information corresponding to the number through the brand's official website or after-sales service. If the number does not match the overall service life of the equipment or there are signs of grinding or alteration, be alert to the possibility of refurbished or replaced parts.

3. Verification of the authenticity of the hour gauge: Some refurbished machines reduce their usage time by tampering with the hour gauge. You can check the original operation data in the equipment control system or inspect the replacement records of hydraulic oil and engine oil. If the time shown on the hour gauge is significantly inconsistent with the degree of oil wear, there may be refurbishment fraud.

4. Consistency judgment of structural component wear: The degree of wear of structural components in original factory equipment is directly proportional to the service life. Refurbished machines may only replace vulnerable parts while neglecting concealed areas such as drill pipe connections and chassis brackets. If it is found that some parts are brand new but the overall frame shows obvious aging, further investigation is needed to determine whether it is refurbished.

5. Inspection of circuit and pipeline layout: The original factory's circuit and pipeline layout is regular, with clear markings and fixed clamps. Refurbished machines, due to maintenance or component replacement, often have messy wiring, mismatched pipeline interfaces, and even non-standard operations such as tape entanglement and temporary wiring. These are all typical characteristics of refurbishment.

6. Maintenance Records and Ownership Traceability: The seller is required to provide complete maintenance ledgers and ownership transfer records. If there are gaps in the records, key maintenance information is missing, or the ownership has changed multiple times without reasonable grounds, it may be to cover up the refurbishment history. At the same time, you can contact the previous user unit to verify the actual usage status of the equipment to reduce information asymmetry.

In conclusion, the risks of refurbished rotary drilling RIGS in the second-hand market objectively exist and are difficult to identify. Buyers need to make a comprehensive judgment based on multiple dimensions such as appearance inspection, component verification, and record traceability. If necessary, they can entrust professional third-party institutions to conduct inspection and evaluation to avoid falling into procurement traps due to ignoring refurbishment traces and ensure the quality of equipment procurement and the stability of later use.
