Capabilities
Unionlever Oilfield Equipment (OFS) serves as the Group’s dedicated oilfield equipment division, integrating engineering coordination, API-compliant manufacturing, independent quality control, and global supply chain capabilities to deliver reliable, field-ready solutions worldwide.
Quality & Inspection Overview
Quality and inspection represent the final and most critical safeguard before oilfield equipment is released to the field.
At Unionlever OFS, quality control is embedded throughout sourcing, manufacturing coordination, inspection, and delivery—ensuring every product meets contractual, technical, and operational requirements for international oil & gas projects.
Our quality and inspection framework is backed by Unionlever International Group (Hong Kong), established since 2008, reflecting years of accumulated field experience, strict quality discipline, and international project requirements.
Why Quality Control Matters
The Chinese oilfield manufacturing market includes factories of very different levels.
Without professional quality control, direct factory sourcing can expose clients to significant technical and operational risks.
Unionlever OFS acts as an independent quality gate, ensuring that only products meeting contractual, technical, and operational requirements are delivered.
Standards & Compliance
Unionlever OFS supplies products designed and manufactured in accordance with relevant API standards, including:
● API 7-1 – Drilling equipment
● API 5DP – Drill pipe
● API 16A / 16C – Well control equipment
● API 7K – Handling and hoisting equipment
Applicable standards are selected based on product type, service conditions, and project-specific requirements.
Cost Control Without Compromising Safety
Unionlever OFS understands the Chinese manufacturing landscape and market dynamics in depth. This allows us to:
● Select the right factory for the right product
● Balance quality requirements with realistic cost targets
● Avoid unnecessary over-specification
● Help clients control budgets without compromising drilling safety or efficiency
Our role is not simply to place orders, but to make informed quality and manufacturing decisions on behalf of our clients—balancing safety, compliance, and cost efficiency without sacrificing drilling performance or operational reliability.
Inspection & Testing Scope
Quality inspection typically includes:
● Dimensional inspection
● Visual and surface condition checks
● Hardness testing
● Pressure and functional testing (where applicable)
● Material traceability verification
Inspection scope can be expanded according to project specifications, contractual terms, or third-party inspection requirements.
NDT & Third-Party Inspection
Upon request, Unionlever OFS coordinates advanced inspection services, including:
● PMI (Positive Material Identification)
● NDT such as UT, MT, PT
● Dimensional and functional verification
Third-party inspection can be arranged through internationally recognized agencies such as SGS, BV, TUV, DNV, or client-nominated inspectors.
Quality Responsibility Under OFS
At Unionlever OFS, quality responsibility does not end at inspection reports or factory acceptance.
We take ownership of quality outcomes throughout sourcing, inspection coordination, documentation, and delivery—ensuring equipment is verified, compliant, and field-ready before shipment.
This accountability-driven approach allows international clients to source from China with confidence and reduced operational risk.
