Then the internal pipe coating or the external pipe coating is applied. Most coating methods and materials come in layers. There are dual coatings and three layer coating techniques. The internal coatings for gas pipelines differs in the coating material from those for the water pipe lines. There are specific material grades for specific coating applications. The external coated pipeline is used in undersea, under water, underground and in the open atmospheric applications. The internal coated pipe is used in oil and gas, water, chemical and food processing plant applications. Please contact us for internal and external coated pipe prices and more information.
internal and external coating is applied on metallic objects, especially pipes of all grades of metals. The stainless and carbon steel pipes come with the internal and external coating.
