Wireline Hose Inspection Service for Global Oilfield and Well Intervention Compliance
As an ISO/IEC 17025 accredited laboratory, we deliver a specialized wireline hose inspection service that verifies pressure integrity, mechanical strength, dimensional accuracy, and long-term reliability of high-pressure hose assemblies used in oilfield wireline operations. Our wireline hose inspection service supports manufacturers, service companies, and exporters who must demonstrate compliance with API 7K, API 16C, ISO 6805, and regional well control standards across the European Union, North America, the Middle East, and Asia. Every inspection is performed under our CNAS-accredited quality system, producing reports accepted by notified bodies, drilling contractors, and procurement authorities worldwide.
Product Samples We Regularly Test in Our Wireline Hose Inspection Service
- Wireline pressure control hose assemblies — with multiple layers of high-tensile steel wire reinforcement and elastomeric liners
- Grease injection and hydraulic control hoses — for wireline valve operation, blowout preventer control, and pressure compensation
- Quick-connect and hammer union wireline hoses — with integral end fittings and swaged or crimped connections
- High-temperature and sour service wireline hoses — for geothermal, hydrogen sulfide, and deep well applications
- Multi-line flat packs and bundled wireline hose assemblies — for simultaneous hydraulic, chemical, and signal transmission
- Reeled wireline hose assemblies — on transportable or offshore spooling units for well intervention and workover
- Custom-length and specialty wireline hoses — with non-standard end connections, fire-resistant jackets, or buoyancy elements
Core Wireline Hose Inspection Service for Pressure Integrity and Mechanical Strength
- Hydrostatic proof pressure test per API 7K and ISO 6805 — the wireline hose assembly is pressurized with water to a minimum of 1.5 times the rated working pressure and held for a code-specified duration, with zero visible leakage, pressure decay, or permanent deformation permitted to verify the hose can safely contain wellbore pressure during wireline operations.
- Burst pressure and ultimate strength verification per ASTM D380 and API 7K — the hose is pressurized until rupture to determine the ultimate safety margin, which must exceed a minimum factor of 2.5 times the rated working pressure for wireline pressure control applications.
- Change in length and diameter under pressure per ISO 6805 — the hose is pressurized to the rated working pressure and the elongation and diametrical expansion are measured to ensure the wireline hose maintains stable geometry under load and does not whip or twist during pressure cycles.
- Tensile pull test on the complete hose assembly per ASTM D380 and API 16C — a defined axial tensile load is applied to the hose end fittings to verify the crimped or swaged connection withstands the pulling forces encountered during spooling, deployment, and retrieval of wireline tools.
- Flexural and bending radius verification per ISO 6805 and customer specifications — the wireline hose is bent to its minimum rated radius at rated pressure and inspected for kinking, flattening, or loss of cross-sectional area that would restrict flow or damage the reinforcement layers.
- Cyclic pressure and impulse fatigue testing per API 7K and customer protocols — the hose is subjected to thousands of pressure pulse cycles between zero and rated pressure to simulate the repetitive loading of wireline valve actuation and well control operations, with post-test integrity verification.
Dimensional, End Fitting, and Visual Inspection in Our Wireline Hose Inspection Service
- Inner diameter, outer diameter, and wall thickness measurement per API 7K and ISO 6805 — precision bore gauges, laser micrometers, and ultrasonic thickness instruments verify that all dimensions conform to the specified tolerances, ensuring correct flow capacity and fitting compatibility.
- End fitting thread and seal surface inspection per API Spec 5B and ASME B1.20.1 — calibrated thread plug and ring gauges, along with optical comparators, verify that the threaded connections, hammer unions, and flanged ends meet the specified form, pitch, and sealing surface finish.
- Visual inspection of the hose cover, reinforcement, and end fittings under D65 illumination — systematic examination for cuts, abrasions, bulges, corrosion, and fitting damage against agreed acceptance criteria, with photographic documentation of any non-conformities.
- Swaged and crimped fitting integrity by radiographic and dye penetrant inspection — the critical junction between the hose and the metal end fitting is examined by digital radiography and liquid penetrant testing to detect cracks, incomplete crimping, or material separation that could cause blow-out under pressure.
Non-Destructive Testing and Corrosion Protection Evaluation for Wireline Hoses
- Magnetic particle inspection of steel end fittings and collars per ISO 17638 and ASTM E709 — the metal components are examined for surface-breaking fatigue cracks, forging laps, and corrosion pitting that could initiate failure at the hose-to-fitting transition.
- Ultrasonic thickness mapping of the hose wall and end fitting barrel per ASTM E797 — the remaining wall thickness is measured to detect internal erosion, corrosion, or delamination between the elastomeric liner and the steel reinforcement layers.
- Neutral salt spray and cyclic corrosion testing per ISO 9227 and ASTM B117 — the wireline hose assembly with its end fittings and protective coatings is exposed to salt fog to evaluate red rust and white corrosion, ensuring durability in offshore and coastal well intervention environments.
- Coating thickness and adhesion on end fittings per ISO 2178 and ISO 2409 — the dry film thickness of paint or phosphate coatings is measured, and the adhesion is tested to verify long-term corrosion protection of the metallic components.
Report Recognition and ISO/IEC 17025 Compliance
All inspection and test methods described in this wireline hose inspection service are covered by our ISO/IEC 17025 scope of accreditation. Our inspection reports are accepted by European notified bodies under the Pressure Equipment Directive, by North American oilfield service companies referencing API and ASTM standards, and by regulatory and procurement authorities across the Middle East, Australia, and Asia. Whether you require a complete qualification of a new wireline hose assembly, a pre-shipment batch inspection, or a root cause failure analysis of a hose rupture, our laboratory provides the measurement accuracy and oilfield equipment expertise that the global well intervention industry demands.
