Pipe Inspection,Testing & Marking Requirements to Ensure gi pipe specification Surface treatment
The carbon steel pipe standards require only that the finished pipe shall be reasonably straight. ASTM A312M (in ASTM A999M) requires a welded stainless steel pipe to be straight to within 3.2 mm over 3.0 m lengths. Generally, the thumb rule is that 1 mm per meter is acceptable.Pipe Class and piping specifications Must Know of Pipe gi pipe specification Surface treatmentTo fully understand pipe class and piping specification you must know the basics of the piping. Pipe covers a very large part of any process plant.

HOT DIP GALVANIZED COATING PROCEDURE
Pickling - Scale and rust normally are removed from the steel surface by pickling in a dilute solu-tion of sulfuric acid (5-15% by volume) or ambient temperature hydrochloric acid. Fluxing - Fluxing is the final surface preparation step in the galvanizing process. Fluxing re-HOT DIP GALVANIZED - AK SteelSURFACE PROTECTION AND LUBRICATION To prevent staining in transit and storage, it is recommended that ZINCGRIP Steel be supplied with a rust-preventive oil.
