Alloy Acid Piping
In the past decade, acid piping has advanced to metallic alloys as the material of choice. This is due to the inherent advantages of alloy acid piping over conventional materials.
Cast Iron Piping Alloy Piping
High corrosion rate (upto 2.5mm/yr)
Low corrosion rate (less than 0.025mm/yr)
Large number of flanges therefore higher risk of acid leaks
Welded construction reduce number of flanges minimizing risk of acid leaks
Iron sulphate formation (greenish sludge) causing plugging of mist eliminators and packing
No iron sulphate formation due to negligible corrosion resulting in reduced plugging/maintenance of tower internals
Constant requirement of maintenance and inventory of spares in case of acid leaks. No possibility of welding
Pratically zero maintenance and no requirement for any spares. Full possibility to weld and repair on-site using conventional welding techniques
Difficult handling due to heavy weight and bulky
Easy erection and flexibility due to light weight and compact size
Low ductility, higher risk of brittle failure resulting in lower safety levels
Higher ductility, minimized risk of brittle failure resulting in higher safety levels
Designed and operated at lower velocities due to risk of erosion and corrosion
Designed and operated at higher velocities without risk of erosion and corrosion
The life cycle cost of Galiakotwala Alloy piping will be lower due to significant reduction in maintenance. Once installed alloy acid piping will usually last the full life of the plant with minimal maintenance. Alloy acid piping has proven itself with many installations worldwide, more than 40,000m of alloy acid piping has been installed all over the world.
