Material Properties
Nickel Alloy 625 / UNS N06625 is suitable for control line applications requiring high corrosion resistance and material stability, commonly found in complex media and harsh environments. For encapsulated control lines, the metal core tube handles pressure resistance and corrosion resistance, while the outer Rilsan PA 11 layer provides additional protection and cable management; this combination is better suited for long-term use scenarios. MTSCO can provide corresponding specifications based on project standards, length requirements, and coating needs, facilitating unified selection by the engineering team.
Rilsan PA 11 Encapsulation
Rilsan PA 11 is one of the most common encapsulation materials used in control line products, suitable for encapsulated control line solutions requiring external protective coating. For control lines, the encapsulation layer not only provides external protection but also impacts on-site installation, reel management, and overall structural compatibility. Rilsan PA 11 is compatible with Alloy 625 tubing and is suitable for project-specific selection and customized production. In addition to Rilsan PA 11, MTSCO also offers encapsulation materials such as FEP, PVDF, and Santoprene TPV, allowing customers to select the optimal solution based on specific operating conditions, structural requirements, and project standards.
