Ukusetshenziswa kwe-ASTM A671/A671MIpayipi Lensimbi LSAW

Inani eliphansi le-ASTM inqwaba yamapayipi ensimbi angama-252

Inqubo Yokukhiqiza

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

Ukuhlola ipuleti le-Ultrasonic → ukugaya onqenqemeni → ukugoba ngaphambili → ukwakha → Ukushisela kwangaphambili → Ukushisela kwangaphakathi→ Ukushisela kwangaphandle → Ukuhlolwa kwe-Ultrasonic → Ukuhlolwa kwe-X-ray → Ukwandisa → ukuhlolwa kwe-hydraulic →l.I-Chamfering → Ukuhlolwa kwe-Ultrasonic → Ukuhlolwa kwe-X-ray → ukuhlolwa kwezinhlayiyana kazibuthe ekupheleni kweshubhu

Ukwehluka Okuvumelekile Kwesisindo Nobukhulu

1. Ububanzi Bangaphandle-Kusekelwe esilinganisweni esiyindilinga ±0.5% sobubanzi obushiwo bangaphandle.

2. Ngaphandle Kwe-Roundness-Umehluko phakathi kwamadayamitha angaphandle amakhulu namancane.

3. Ukuqondanisa-Kusebenzisa i-10 ft (3m) yokuqondisa ebekwe ukuze iziphetho zombili zithintane nepayipi, 1/8 in. (3mm).

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

5. Ubude obuneziphetho ezingashintshiwe buyoba phakathi kuka--0+1/2 in. (-0+13mm) walokho okushiwo.Ubude obuneziphetho ezenziwe ngomshini buzoba njengokuvunyelwana ngabo phakathi komkhiqizi nomthengi.

Ukuhlolwa komshini weI-ASTM A671 LSAW Ipayipi Lensimbi Yekhabhoni:

Ukuhlolwa Kokuqina—Izici eziqinile eziguquguqukayo zelunga elishiselwe zizohlangabezana nezidingo ezincane zamandla okugcina aqinile wento yepuleti elishiwo.

Ukuhlola okugobile okuqondiswa-okuqondiswa-okuguquguqukayo—Ukuhlolwa kokugoba kuyokwamukeleka uma kungekho mifantu noma okunye ukukhubazeka okudlula u-1/8 in. (3mm) kunoma iyiphi indlela ekhona ensimbi yokushisela noma phakathi kokushisela nesisekelo sensimbi ngemva kokugoba.

Ukuhlolwa kwe-Radio-graphic-Ubude obugcwele be-weld ngayinye yekilasi X1 ne-X2 buzohlolwa nge-radiographic ngokuhambisana futhi kuhlangatshezwane nezimfuneko ze-ASME Boiler and Pressure Vessel Code, Isigaba sesikhombisa, isigaba UW-51.
