1. Introduction to Coiled Chemical Injection Stainless Steel Tubing
Coiled Chemical Injection Stainless Steel Tubing is a continuous length of seamless or welded-and-drawn stainless steel tubing specifically designed for delivering chemicals such as corrosion inhibitors, methanol, scale inhibitors, or wax control agents into oil & gas pipelines, subsea wells, and processing systems.
Unlike conventional straight-length pipes, stainless steel coiled tubing offers:
Continuous lengths up to thousands of meters without joints.
Superior corrosion resistance against harsh offshore and subsea environments.
Reduced leak points and easier installation.
This makes it the preferred choice for offshore chemical injection lines, subsea umbilicals, and onshore chemical processing plants.
2. Why Use Stainless Steel Coiled Tubing for Chemical Injection?
2.1 Corrosion Resistance in Harsh Environments
Offshore and subsea applications often face high levels of H₂S, CO₂, and chlorides, which can cause severe corrosion. Materials such as Duplex 2205, Alloy 825, and Alloy 625 offer exceptional resistance to:
Pitting corrosion
Crevice corrosion
Stress corrosion cracking
2.2 Long Continuous Lengths
Our continuous length stainless steel coiled tubing eliminates the need for multiple fittings, reducing potential leak points and increasing system reliability.
2.3 High Strength & Flexibility
Duplex stainless steel provides both high mechanical strength and flexibility, allowing installation in tight spaces such as subsea umbilicals and platform injection systems.
3. Common Applications
Stainless Steel Coiled Tubing for Chemical Injection is widely used in:
Offshore oil & gas platforms – injection of corrosion inhibitors and wax inhibitors into production wells.
Subsea umbilicals – integrated into control lines to deliver methanol and hydrate inhibitors to subsea wellheads.
Pipeline protection – injecting chemicals to prevent hydrate formation in gas pipelines.
Refineries & chemical plants – dosing high-purity or corrosive fluids into process lines.
