High-Performance Hydraulic Corrosion Coupons and Chemical Injection Quills for Oil & Gas Pipelines
In the oil and gas industry, ensuring pipeline integrity and process safety is non-negotiable. One of our recent projects involved the custom manufacturing and delivery of hydraulic corrosion monitoring coupons and chemical injection quills, designed to be installed in high-pressure oil and gas pipeline systems.
This case study showcases how our engineering team developed a complete corrosion monitoring and chemical dosing solution to help our client in the petroleum sector maintain operational efficiency and extend pipeline lifespan.
Project Background
Our client, a leading energy service provider operating upstream facilities, faced challenges with internal pipeline corrosion caused by aggressive fluids and gas mixtures. They required a reliable solution that could:
Monitor real-time corrosion rates
Inject corrosion inhibitors directly into the process stream
Withstand harsh environmental and pressure conditions
Comply with international oilfield equipment standards
To meet these requirements, we proposed a combined solution featuring hydraulic corrosion coupons and precision-engineered injection quills.
Solution Overview: Corrosion Coupons & Chemical Injection Quills
Hydraulic Corrosion Coupons
Our corrosion coupons are specifically designed to provide direct, quantifiable data on metal loss inside pipelines. Each coupon holder is made from high-grade stainless steel with a durable blue-coated head, optimized for long service life and easy field identification.
Chemical Injection Quills
The stainless steel chemical injection quills allow precise delivery of corrosion inhibitors, scale inhibitors, and other treatment chemicals into the pipeline flow. They are designed to ensure even dispersal and avoid backflow or chemical buildup at the inlet point.
Key Features:
Precision-machined to meet ASME and NACE standards
Integrated with check valves to prevent reverse flow
High-pressure operation up to 10,000 PSI
Corrosion-resistant material to match pipeline metallurgy
Manufacturing & Quality Assurance
Each unit was CNC-machined in our ISO-certified facility and underwent a strict quality control process, including:
Hydrostatic pressure testing
Surface finishing and anti-corrosion coating
Dimensional inspection
Thread and valve integrity checks
Our in-house QA team ensured every component met both client specifications and international industry standards.
Results & Client Feedback
The installed corrosion monitoring system and chemical injection units have significantly improved the client's ability to track corrosion trends and proactively manage pipeline integrity.
Initial deployment results showed:
A 20% reduction in corrosion rate within the first 60 days
Increased chemical dosing efficiency
Reduced unplanned downtime due to internal corrosion failures
The client praised the durability and ease of installation of our components and has since placed follow-up orders for additional units in other facilities.
Conclusion
This case study highlights our commitment to delivering reliable, high-performance corrosion control equipment for the oil and gas sector. Whether it’s upstream, midstream, or downstream applications, our corrosion coupons and chemical injection quills are trusted by industry leaders to protect their critical infrastructure.
