​🛠️ Wrapping & Coating Process (Key Steps)
​1. Surface Preparation (Cleaning)
​Coating lagane se pehle pipe ko saaf karna zaruri hai taaki coating achhe se chipak sake.
​Method: Sand Blasting ya Shot Blasting ka use karke pipe ko 'Grey Metal' finish tak saaf kiya jata hai (Standard: Sa 2.5).
​2. Priming
​Saaf kiye gaye pipe par ek liquid primer lagaya jata hai jo pipe aur wrapping tape ke beech "Gloo" ka kaam karta hai.
​3. Wrapping/Coating Application
​Cold Applied Tapes: Manual ya machine se tape ko pipe par lapeta jata hai (Overlap ka dhyan rakhte huye).
​3LPE (3 Layer Polyethylene): Isme 3 layers hoti hain—Epoxy, Adhesive, aur Polyethylene. Ye sabse mazboot mani jati hai.
​4. Quality Check (Holiday Test) ⚡
​Ye sabse important step hai. Ek Holiday Detector Machine ka use karke puri line par high voltage pass kiya jata hai. Agar coating mein kahin bhi chota sa chhed (pinhole) hoga, toh machine 'beep' karegi. Ise "Holiday" kehte hain.
