How is FBE coating applied?
The application of FBE powder coatings involves pre-heating the substrate to the required temperature (typically 240°C) by use of induction coils, followed by application of the powder coating. PIH offers powder coating application services.
What is pipeline coating?
A pipeline coating is a cost effective and viable solution to maintain pipelines’ integrity. This coating provides a constant protective lining that helps save pipelines from the damaging effects of corrosion. Pipeline coating is one of the most reliable corrosion prevention methods used by industries today.
What is field joint coating?
Field-joint coatings are applied on offshore lay vessels where offshore pipelines are welded together in either single or double joint segments. Exposure in a hostile environment and vulnerable to corrosion, the welded area is often the weakest point within a pipeline.
How many types of pipe coating are there?
However, for the sake of this article, prediminanently there are following types of external anti-corrosion coatings: Fusion Bonded Epoxy (FBE) Coating. Three Layer Poly Ethylene/ Propylene (3LPE/ 3LPP) Coating. Coal Tar Enamel (CTE) Coating.
What is 3LPE coating?
3-Layer Polyethylene (3LPE) is a multilayer coating composed of three functional components: A high performance Fusion Bonded Epoxy (FBE) primer, followed by a copolymer adhesive and an outer layer of polyethylene which provides tough, durable protection.
Why are pipelines coated?
Coatings reduce corrosion. Corrosion can result on the inside of a pipe due to corrosive components of the natural gas being transported. And it can result on the outside of the pipe due to components of dirt, rock, and groundwater. Corrosion degrades pipe and increases the risk of explosions.
What is CP coating?
Cathodic protection (CP) in combination with organic coatings is a well-known corrosion protective system for steel structures submerged in seawater. The coatings are exposed to an environment that may cause loss of adhesion, i.e. cathodic disbonding.
What is parent coating?
In this document, “parent coating” is sometimes used synonymous with linepipe coating. In order to facilitate girth welding, areas at each end of the individual pipe length are left uncoated. These areas are normally coated after welding, by applying a “field joint coating” (FJC) system.
How do you protect welding joints?
Rust Prevention tips
- Design them out. The best way of preventing rust in overlapping joints is to not have any overlapping joints. Use butt welds instead.
- Use seal welds. Your overlap joint certainly has two sides, and possibly four.
- Caulk. Yes, use caulk to fill the space between the plates.
- Weld-through primer.
What is CWC pipe?
The concrete coated pipe also called concrete weight coating pipe (CWC pipe), it is the steel pipe external with concrete weight coating (Mixed with cement, aggregates, reinforced steel mesh, and water), to provide strong downward force protection (Impact from anchoring, dredging activity, fishing, ship sinking) or a …
What do you mean by FBE?
Fusion bonded epoxy (FBE) coating is a powder coating broadly used to provide protection to pipelines, steel pipes and a wide range of piping bonds. FBE coatings are thermoset polymers by nature.
