MATERIAL RECIEPT & VISUAL INSPECTION 2. SURFACE PREPARATION 3. GALVANIZING 4. INSPECTION 1. MATERIAL RECIEPT & VISUAL INSPECTION Material is first inspected to check quantities, description, grade or specification and condition of goods (light, medium or heavy rusty). Job order should be issued for identification & traceability. 2. SURFACE PREPARATION The Surface preparation for Galvanizing consists of 5 Stages Chemical Treatment Degreasing, Pickling, Rinsing, Fluxing & Preheating. * I. Degreasing In case of the article surface is with oil and grease the article shall be chemically treated with Acidic Degreasing Agent, the immersion time is depend to oil, grease, dirt…etc. visibility the minimum immersion time is 3 minutes the maximum is 7 minutes and it shall be checked visually after immersion. *II. Pickling, After Acid Degreasing (if done) to ensure that articles are immersed in Hydrochloric Acid solution , The immersion time is depend to the item condition generally heavy rusted items will take 25 to 40 minutes in solution with limits 5% to 16% a visual check shall be well done after pickling to avoid any oxides to run to next stage. 3 | P a g e *III. Rinsing The article surface shall be rinsed with fresh water in the Rinsing Tanks to remove the Hydrochloric Acid residuals & iron salts left over from Stage 2. Double water rinsing baths are available to rinse the items before processing the flux. *IV. Flux pretreatment Bath Temperature is 40°C to 65°C, Time 1min to 3min Fluxing is the final surfa ...
