Inqubo Yokukhiqiza

lsaw abakhiqizi bamapayipi

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 kwe-ASTM A671 LSAW Ipayipi Lensimbi Lekhabhoni:

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

Ukuhlola okugobile okuqondiswa-okuguquguqukayo—Isivivinyo sokugoba siyokwamukeleka 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 Kwezithombe Zomsakazo-Ubude obugcwele be-weld ngayinye yekilasi X1 ne-X2 buzohlolwa ngokwemisakazo ngokuhambisana futhi kuhlangatshezwane nezimfuneko ze-ASME Boiler and Pressure Vessel Code, Isigaba sesikhombisa, isigaba UW-51.

Ukubukeka kwe-ASTM A671 LSAW Carbon Steel Pipe:

Igama noma umaki womkhiqizi
Inombolo yesicaciso(idethi yonyaka noma edingekayo)
Usayizi(OD, WT, ubude)
Ibanga (A noma B)
Uhlobo lwepayipi( F, E, noma S)
Ingcindezi yokuhlola(ipayipi lensimbi engenamthungo kuphela)
Inombolo Yokushisa
Noma yiluphi ulwazi olwengeziwe olucaciswe ku-oda lokuthenga.

Ulwazi loku-oda

Ubuningi (izinyawo, amamitha, noma inombolo yobude)
Igama lezinto (ipayipi lensimbi, i-fusion kagesi eshiselwe)
Inombolo yokucaciswa
Izilinganiso zebanga nekilasi
Usayizi (ngaphandle noma ngaphakathi ububanzi, evamile noma ubuncane udonga ukujiya)
Ubude (okuqondile noma okungahleliwe)
Qeda ukuqeda
Izinketho zokuthenga
Izidingo ezengeziwe, uma zikhona.
