Precision Chemical Injection Quill Solution for Pipeline Corrosion Control
At Shenyang Emt Piping Technology Co.,ltd., we specialize in delivering high-performance flow control solutions for industrial applications. One of our latest success stories involves the custom design and supply of chemical injection quills for a large-scale pipeline system in the petrochemical sector. This case study demonstrates how our injection quill solution helped our client achieve accurate dosing, corrosion control, and operational efficiency.
Project Overview
Industry: Oil & Gas / Petrochemical
Location: Middle East
Application: Corrosion Inhibitor Injection in Natural Gas Pipeline
Product: Stainless Steel Chemical Injection Quill with Double Ball Valve System
The client required a robust solution for injecting corrosion inhibitors into a high-pressure gas pipeline. The system needed to be safe, durable, and resistant to aggressive chemicals, while also allowing for accurate flow control and easy maintenance.
Challenges Faced
High-pressure environment with potential flow turbulence
Need for precise chemical dosing to prevent under or over-injection
Corrosive media requiring material compatibility
Requirement for safe isolation during maintenance
After a thorough consultation, our engineering team proposed a customized chemical injection quill made from 316L stainless steel, paired with a double ball valve system for enhanced safety and operational control.
Product Features
Material: 316L stainless steel – excellent resistance to corrosion and chemical attack
Design: Extended nozzle with tapered tip to ensure deep and accurate injection into the pipeline core
Isolation Valves: Dual ball valves with ergonomic handles for easy operation
Connection: Flanged end for secure and leak-free installation
Pressure Rating: Suitable for up to 6000 PSI
Optional Accessories: NRV (Non-return valve), sample ports, and bleed valves
These features ensure safe chemical injection under pressure, protect pipeline integrity, and extend the life of downstream equipment.
Implementation & Results
The injection quills were delivered on time and installed successfully across multiple injection points. Our client reported the following benefits:
Improved corrosion control, reducing pipeline maintenance downtime
Accurate chemical dosing, minimizing chemical waste and environmental impact
Enhanced safety during operation and servicing
Longer service life due to high-grade material and precision machining
The ergonomic ball valve handles and modular design allowed site technicians to isolate and service the units without disrupting pipeline flow.
Client Feedback
“We were impressed with the build quality and performance of the chemical injection quills. Installation was smooth, and the system now runs more efficiently with greater control over corrosion management.”
– Project Manager, Petrochemical Client
