Pipe kya hai aur Pipe Inspection kaise karte hai ?

आज के इस वीडियो में हम pipe, उसके टाइप्स, मटेरियल एंड पाइप इंस्पेक्शन methodology के बारेमे discuss करेंगे
• Pipe is the basic raw material for piping, skid and other industrial systems.
• All you know the shape of pipe is round and hollow having standard lengths of 5.8 to 6.3 meter normally.
• Pipes are denoted by its nominal bore size and its thickness.
• Seamless pipes are normally gives a nomenclature as Schedule pipe.
50NB schedule 80
• ASTM A 106 or ASME SA 106 & ASTM A53 or ASME SA 53 for carbon steel pipe.
Stainless steel seamless pipe ASTM A312 type 304 and 316.
• Pipe is the basic raw material for piping, skid and other industrial systems.
• पाइप यह स्किड , इंडस्ट्रियल piping , handrails इत्यादि assemblies में use होनेवाला एक बेसिक raw मटेरियल है
• All you know the shape of pipe is round and hollow having standard lengths of 5.8 to 6.3 meter normally.
• जैसे की आप सभी को पता है पाइप का क्रॉस sectional shape राउंड होता है एंड उसका standard length normally 5.8 मीटर to 6.3 मीटर ऐसा vary करता है
• Pipes are denoted by its nominal bore size and its thickness.
• पाइप की साइज उसके nominal bore एंड thickness के हिसाब से denote होती है
TYPES OF PIPES
1. SEAMLESS PIPES
• Its name defined its shape that is no any type of seam/joint along its length.
• इसका नाम ही इसको define करता है की इस पाइप में किसी भी प्रकार का कोई joint और seam नहीं होता
• Seamless pipes are normally gives a nomenclature as Schedule pipe.
• सीमलेस पाइप को schedule पाइप भी कहा जाता है
• Schedule defines the thickness of pipe
• schedule पाइप का thickness बताता है
• if the schedule is high then pipe is having higher thickness and if schedule is small the pipe is having lesser thickness.
• schedule अगर ज्यादा है तो उस पाइप का thickness भी ज्यादा रहेगा और schedule अगर कम है तो उस पाइप का thickness भी कम ही रहेगा
• Seamless pipes are used in high pressure rating applications.
सीमलेस पाइप्स high pressure वर्क application के लिए use होते है
Example: 50 NB sch. 40
50NB schedule 80 etc.
Materials seamless of pipe
• ASTM A 106 or ASME SA 106 & ASTM A53 or ASME SA 53 for carbon steel pipe.
• कार्बन स्टील में अगर seamless पाइप है तो उसका मटेरियल normally astm A 106 और ASTM A53 ये होते है
• for Stainless steel seamless pipe ASTM A312 type 304 and 316.
• Stainless स्टील में अगर seamless पाइप है तो उसका मटेरियल normally ASTM A312 type 304,310, 316 etc. ये होते है
2nd type is ERW pipe
• This pipes having a seam/joint over its length.
• इस टाइप के पाइप्स में throughout the length एक वेल्डिंग joint होता है
• This pipes are manufactured by electric resistance welding hence called ERW pipes.
• यह पाइप्स इलेक्ट्रिक resistance वेल्डिंग से बनाते है इसीलिए इन्हे ERW पाइप्स कहते है
• Thickness of ERW pipes defines by the classes.
•
• ERW pipes are used in low pressure application or atmospheric pressure applications.
•
Example: ERW pipe 50 NB class A.
There are three different classes as per thickness range
Class A, Class B & Class C
Material
• IS 1239, IS 3589 etc. for Mild steel &
• ASTM A312 type 304 and 316 for Stainless steel pipe.
3rd one is EFW pipe
• This pipes are same as ERW pipe but only joining process is different in both.
•
• EFW pipes are manufactured by Electric fusion welding.
•
Let us see some ABBREVIATIONS used in pipe and piping industry
• NPS stands for: Nominal pipe size.
• DN/NB stands for: Nominal diameter / Nominal bore.
• ID stands for: Inner diameter.
• OD stands for: Outer Diameter.
• SCH stands for: Schedule for thickness of pipe.
• STD stands for: Standard weight pipe thickness.
• XS stands for: Extra strong pipe thickness.
• XXS stands for: Double extra strong pipe thickness.
INSPECTION OF PIPES
• While inspection of pipes following points should be check thoroughly.
• Visual appearance of pipes that is pitting, corrosion, etc.
•
• should not be any Physical damage of pipes such as dent, bend, break, etc.
•
• If pipes for higher pressure application needs to carry Ultrasonic test for flaw/defect detection.
• Manufacturer also needs to do hydro test for each pipe & we can confirm it by checking their test certificates.
• All chemical values should be match with standard material description.
• test certificate के ऊपर mentioned किया केमिकल values स्टैण्डर्ड से मैच होना जरुरी है
• All mechanical test values should meet the minimum strength required for that material.
• test certificate के ऊपर mentioned किये मैकेनिकल values भी स्टैण्डर्ड से मैच होना जरुरी है
• All heat numbers mentioned on test certificates need to identify on actual pipes.
• Pipe outer diameter and wall thickness are very important measurable parameters.
• If the pipes came directly from manufacturer then he should give his test certificate along with pipes with his endorsement.
In endorsement manufacturer should mention the quantity of pipes, its specification, date of supply, signature, supplied to details etc.

Aisa kaun sa pipe Hai Jiski ID ki machining Nahin Karni hoti hai

Seamless pipes did not required inside machining
