🔹 1. Rolling Bend Kya Hota Hai?
Rolling bend ek aisa bend hota hai jisme pipe horizontal + vertical dono directions me angle par move karta hai.
Agar sirf vertical me ho → simple elbow
Agar sirf horizontal me ho → offset bend
Agar dono me ho → rolling bend

🔹 2. Horizontal Rolling in Isometric
Jab pipe horizontal plane me roll karta hai (yaani zameen ke level par hi lekin ek angle me chal raha hai), tab isometric drawing me:
Pipe ka direction ek hi horizontal plane me hota hai
Line ko 30° angle (isometric projection angle) par draw karte hain
Dimension me hamesha true length + offset dikhaya jata hai
---
🔹 3. Isometric Drawing Representation
Start point se pipe ko ek angle me dikhana (jaise East → North-East me roll karna)
Elbow symbols (90°) use karte hain lekin rolling ke hisaab se orientation change hota hai
Drawing me H (Horizontal offset), V (Vertical offset) aur CL (Center line length / true length) mention hota hai
---
🔹 4. Fabrication / Field Purpose
Isometric horizontal rolling ka use hota hai:
Jab pipe ko ek level me rehkar dusre equipment ya line ko avoid karna ho
Space constraints hone par
Proper flow direction maintain karte hue obstacles ko cross karna
---
👉 Example:
A pipe East direction me ja raha hai, lekin usse North-East me le jaana hai bina vertical uthane ke → ye Horizontal Rolling hoga, jo isometric drawing me 30° line ke roop me dikhaya jayega.
