PROJECT DETAILS
Welded field joints are susceptible to corrosion from exposure to moisture, air, and chemicals, which can weaken their structure over time. To prevent this, a protective coating is applied, acting as a barrier to keep the joints safe from corrosive elements and extend their lifespan.
After carefully considering the site conditions, the client decided to use Denso Primer D™ and Denso Ultraflex™ 1250 to protect the field joints.
The surface was prepared using a hand-held power tool. Thereafter Denso Primer D™ was applied to the surface of the field joints. This primer was chosen for its excellent adhesion properties, ensuring a strong bond between the joint and the protective materials.
Next, the joints were wrapped with Denso Ultraflex™ 1250. This tape was selected for its superior corrosion prevention capabilities. Each joint is carefully wrapped, and the PVC backing of Denso Ultraflex™ 1250 provides additional mechanical strength, safeguarding the joints from external elements.
