\n\t\t\t\t\t\t\t\t\tHigh quality painting of piping and equipments as well as structures, is essential to avoid corrosion. It helps ensure long life of a constructed plant and low maintenance costs. Painting involves not only total surface cover but also markings of various types such as line numbers, fluid codes, flow arrows, equipment numbers etc.\n\n\nPainting specification for the project is given by PMC or Client in FEED or BEP. It is updated by material engineer on the project. Engineering firm can use its own standard painting specification if allowed by client.\n\n\nPreparation of painting specification involves understanding environmental factors, location of piping (indoor or outdoor), insulation requirements, operating and design temperatures. It may also involve local rules and regulations as well as availability of materials.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Applicability of Standards<\/p>\n\nPainting Specification is prepared by Material Engineer to assure high quality painting work on the project as per international standards. Various international codes and standards should be followed for painting.<\/span>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
