Basalt Fiber Tech Pty Ltd and Chemco Specialty Coatings Australia partnering in Sustainable Engineering Solutions. has successfully overcome the challenge to revitalize 25 years old corroded steel Pipes .
A combination of BasfiberWrap® and BasfiberMat® provided unique chemical , mechanical, insulation, and durability properties, ideally reinforcing the demanding application which required resistance against high temperatures, acid ,alkali and solvents.
The Basfiber® alternative on the project provided a long term sustainable corrosive solution to the owners with major economical benefits when compared to the original conforming engineered design of Carbon fiber.
Basalt Fiber Tech provides a wide range of engineered Basalt Textiles that can be applied to concrete and steel pipes.
Chemco Specialty Coatings Australia successfully applied BasfiberWrap® with their RB300AR series products as described below:
Industry: Steel Manufacturing
Date: October 2014
Substrate: Externals of Conical Sections of 6mm wall pipe sections
Products:
- BasfiberWrap® and BasfiberMat®
- Chem-tect RB 332AR,
- Epo-chem RC 500GTC
Environment: Abrasive Coke Breeze ranging in temperatures from 60-100̊
Challenge:Inspections found wall thickness to be worn internally after 25 years in service. This was prevalent immediately beyond the weld from the straight sections in the concentric reducers.
Solution:Critical areas to be identified by NDT for the application of the RB 332AR & Alumina Tiles. BasfiberWrap® was chosen over Carbon Fibre due to its natural characteristics providing a combination of improved temperature and abrasion resistance.
Scope:Mechanical Clean and solvent wipe. Trowel application of RB 332AR to the externals.Application of RB 332AR on the weld lows to ensure a firm bed for the tiles to be laid on.Application of Hex Alumina tiles using the RB 332AR providing an abrasion resistant adhesive.Application of BasfiberWrap® Tape and BasfiberMat® using RB 300 Series and top coat using RB 300AR Final top coat using RC 500GTC
Results: Replacement is no longer necessary with an extended life expectancy of 15 years+.
