Coating and Lining:
PipesCoating is fundamental for protecting the pipe against corrosiveenvironment and the pipe's life-length depends directly on the coating.
Our manufacturer apply different types of coatings and linings inaccordance with major standards in order to fulfill our client'srequirements.

• Polyethylene coating (PE):PE coating is extremely efficient against corrosive and aggressiveenvironments and chemical materials. PE coating is applied inaccordance with DIN30670.
• Bitumen Coating and Lining: Bitumen coating and lining is applied in accordance with DIN2461, DIN30673, BS41-64, BS41-47, etc.
• Epoxy Coating and Lining:Epoxy resin is applied after the internal surface treatment iscompleted in accordance with SA2 1/2 requirement is completed. Thisprocedure is applied with sanitary norms and AWWA C-210.
