The primary use of internal coatings is to protect the in
side surface of the tank against corrosion while also protecting the stored
contents from contamination. Technical Data used in the field explained in petroleum courses in
Rawalpindi.
A coating specification should be a clearly defined list of
particulars or instructions. Just as a drawing must give exact dimensions. so
must a coating specification state the exact system to he used. In the
preparation of such a specification consideration must be given to such factors
as (I) types of coatings available. G!) types of surfaces to he coated. (3)
compatibility of coatings. and of coats required on the various types of
surfaces for maximum protection. To secure high-quality coatings. Con
sideration must he given to the following factors. Some more details of petroleum courses
in rawalpindi are as under.
In the broadest sense, any discussion of compatibility should
include a consideration of the ageold problem of heredity and environment.
Environment calculates the compatibility of coatings when applied to
various types of surfaces and the operating conditions to which such coatings
will hc subjected. Heredity concerns itself with the birth of the coating:
formulation. The basic raw materials used in formulating and the art of
formulation itself determine whether two paints will he “capable of existing
together.
Film Thickness:
Coating film thickness is now widely recognized as one of the
most important factors in obtaining desired performance from a coating system.
The required thickness of a coating system will vary, depending on
generic properties of the coating. the type of substrate to which
it is applied. and the severity ofthe environment to which the coating is
exposed. Film thickness for most protective paints and coatings is generally
measured in mils; I mil is % 000 in. TSK Training for Skills and Knowledge is
the best institute in Rawalpindi Islamabad for Pakistani Students who wants to
join petroleum
courses in Rawalpindi.
