Steel Pipe Internal and External Coating & Lining

Steel pipes, like all other materials, are susceptible to corrosion caused by exposure to air, water, soil, and chemical substances. However, this corrosion can be effectively mitigated by applying the right coating and lining materials, tailored to the pipes' specific applications.

 

At Weldell, we are dedicated to maintaining exceptional quality and a keen eye for detail in both our coating and lining processes, just as we are in the manufacturing of our steel pipes.

 

Depending on the requirements of your steel piping projects, we offer various coating and lining solutions, including Polyethylene, Fusion Bonded Epoxy (FBE), Polypropylene, Epoxy, Polyurethane and Concrete coatings.
