Intengo Ephansi I-ASTM Inqwaba Yepayipi Lensimbi engu-252

Inqubo Yokukhiqiza

Inqubo yokukhiqiza i-Longitudinal Submerged-arc Welded (LSAW) Pipe imi kanje:

Ukuhlola ipuleti le-Ultrasonic → ukugaya umphetho → ukugoba ngaphambi kokwenza → Ukushisela ngaphambi kokwenza → Ukushisela kwangaphakathi → Ukushisela kwangaphandle → Ukuhlolwa kwe-Ultrasonic → Ukuhlolwa kwe-X-ray → Ukwandisa → ukuhlolwa kwe-hydraulic → l. Ukuxubha → Ukuhlolwa kwe-Ultrasonic → Ukuhlolwa kwe-X-ray → Ukuhlolwa kwezinhlayiya ze-magnetic ekugcineni kwepayipi

Izinguquko Ezivumelekile Zesisindo Nobukhulu

1. Ububanzi Bangaphandle - Ngokusekelwe ekulinganisweni okujikelezayo ±0.5% yobubanzi bangaphandle obucacisiwe.

2. Umehluko ongaphandle kobubanzi obukhulu nobukhulu obuncane bangaphandle.

3. Ukuqondanisa-Ukusebenzisa umphetho oqondile ongu-10 ft (3m) obekwe ukuze zombili iziphetho zithintane nepayipi, 1/8 in. (3mm).

4. Ubukhulu - Ubukhulu bodonga obuncane kunoma iyiphi indawo epayipini akumele bube ngaphezu kuka-0.01 in. (0.3mm) ngaphansi kobukhulu obubekiwe.

5. Ubude obuneziphetho ezingakashintshwa kufanele bube ngaphakathi kuka-0,+1/2 intshi (-0,+13mm) walokho okuchaziwe. Ubude obuneziphetho ezikashintshwa kufanele bube njengoba kuvunyelwene phakathi komenzi nomthengi.

Ukuhlolwa Kwemishini Kwepayipi Lensimbi Yekhabhoni ye-ASTM A671 LSAW LSAW:

Ukuhlolwa Kokucindezeleka—Izakhiwo zokudonsa eziguquguqukayo zejoyinti elihlanganisiwe zizohlangabezana nezidingo ezincane zamandla okudonsa aphelele ezinto ezishiwoyo zepuleti.

Ukuhlolwa kokugoba okuqondiswa yi-transverse-weld-bend —Ukuhlolwa kokugoba kuzokwamukeleka uma kungekho mifantu noma ezinye iziphambeko ezingaphezu kwe-1/8 intshi (3mm) kunoma iyiphi indlela ezikhona ensimbini yokugoba noma phakathi kokugoba kanye nensimbi eyisisekelo ngemva kokugoba.

Ukuhlolwa kwe-Radiographic - Ubude obuphelele be-weld ngayinye yekilasi X1 ne-X2 kufanele buhlolwe nge-radiographic ngokuhambisana futhi kuhlangatshezwane nezidingo ze-ASME Boiler and Pressure Vessel Code, Isigaba sesikhombisa, isigaba UW-51.

Ukubukeka kwepayipi lensimbi yekhabhoni le-ASTM A671 LSAW:

Igama noma uphawu lomkhiqizi
