Isometric drawing kaise dekhe ,Basic learn isometric PART-4 TEMPLATE

🔹 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. #pipelining #welding #mechanicalengineering
