Industry: Chemical & Petrochemical (PETR)
Application: VPF-Valves, Pipes and Fittings (VPF)
Substrate: Steel

Customer Location: Petrochemical Plant, Saudi Arabia
Application Date: 2018

Products:
Belzona 1111 (Super Metal)

Belzona 1391T

Problem: A new utility sea water cooling facility was commissioned 1 year ago for this plant. Already, the effects of sea water were leading to crevice corrosion on many diameters of pipe line flanges. This was leading to worn out serrations and severe damages on the seating faces. Existing FBE coating failure inside the spools was due to sea water penetration and pitting corrosion on the edges of spool. Leakages observed through various flange faces / weld seams were leading to intermittent shutdowns.

Belzona Facts

The customer has been using Belzona solutions for various maintenance problems before being introduced to flange face forming during a technical presentation. They then first used the “Flange face forming technique” in December 2017 for 25 48-inch and 40-inch flange faces. Due to the successful performance of Belzona formed flanges, the plant specified Belzona forming technique for all 132 damaged flanges during their recent shutdown in November 2018. Competitors tried to copy the forming technique but were ultimately unsuccessful .
