Hello bobby_manmadhan:

As dadw5boys says, and it is good advice and the correct way to work on whatever surface or material you are painting, it is vital there is no grease or oil on the pipe. Hammerite can be applied to rusting surfaces but, it will never be sucessful on a greasy surface.

this standard of NORSOK is applicable to Offshore Platform but can give you some good advice

corrosion prevention

I reccently did a set of hockey goal frames (which I believe to be generic carbon steel) for the local college team. First, I took the entire frame down to the bare shiney metal. I then primed it with rustoleum spray primer. I then painted over that with rustoleum red and white enamel paint, lightly roughing it up between coats every 24 hrs. When I had achieved the desired coverage, I then put on 2 coats of a product called Glisten PC - essentially a 2 part urathane clear coat that dries incredibly hard. While not using terribly sophisticated methods and materials, I can say that the frames held up beautifully to an entire season of 70+ mph puck shots, banging sticks and crashing helmets. The frames were only damaged where the steel skate blades had gouged across a surface. I did 2 full sized nets for less then $50 and still had materials left over, and I can say without exaggeration that the finish looked good enough to be on a car.

You should get with your paint supplier and request the recomended procedure for the products that are avalible for the particular application. Depending on the climate, etc.
