Izinzuzo zokusebenzisa amapayipi ensimbi anomoya enomoya astm a252
Enye yezinzuzo eziphambili zokusebenzisa i-ASTM A252 Spiral Welded Pipe ngamandla ayo aphezulu nokuqina. Lawa mapayipi angamelana nezingcindezi eziphakeme nemithwalo esindayo, ukuzenza elungele ukudluliswa kwamafutha nokuhanjiswa kwegesi, ukuthuthwa kwamanzi kanye nezinhlelo zokusebenza zesakhiwo. Inqubo ye-welding eluhlaza esetshenziselwa ukukhiqizwa iqinisekisa ukuba isibopho esiqinile nesibopho, ukuvumela ipayipi ukuthi libekezele izimo ezinzima.

| Ukuvuselela Iphuzu noma Ukuvuna Amandla, Amaminithi, MPA (PSI) | 205 (30 000) | 240 (35 000) | 310 (45 000) |
| Amandla asheshayo, amaminithi, MPA (PSI) | 345 (50 000) | 415 (60 000) | 455 (66 0000) |
Ukuhlaziywa Komkhiqizo
Insimbi izobe ingabi naphezulu kwe-0,050% phosphorous.
Ukuhlukahluka okuvumelekile ezinsimbi nasezilinganiso
Ubude be-pile yepayipi buzosindwa ngokwehlukana futhi isisindo salo ngeke bahlukane ngaphezu kwe-15% ngaphezulu noma i-5% ngaphansi kwesisindo sayo sethiyori, kubalwa kusetshenziswa ubude baso kanye nesisindo sayo ngeyunithi ngayinye ubude
Ububanzi bangaphandle ngeke buhluka kakhulu kune- ± 1% kusuka kububanzi obucacisiwe be-off
Ubukhulu bodonga nganoma yiliphi iphuzu ngeke bungabi ngaphezu kwe-12,5% ngaphansi kobukhulu bedonga olubekiwe
Ubude
Ubude obungahleliwe obungahleliwe: 16 kuya ku-25ft (4.88 kuya ku-7.62m)
Ubude obungahleliwe obuphindwe kabili: ngaphezulu kwe-25ft kuya ku-35ft (7.62 kuye ku-10.67m)
Ubude be-Uniform: Ukuhluka okuvumelekile ± 1in
Ngaphezu kwamandla,I-Steel Enomoya Amapayipi e-ASTM A252inikeza ukumelana okuhle kakhulu. Lokhu kubaluleke kakhulu kumapayipi avezwe ezimweni ezinokhahlo noma ezintweni ezilimazayo. Ukuhlanganiswa okuvikelayo kwalawa mapayipi kuthuthukisa ukumelana kwabo nokugqwala, kuqinisekisa impilo yenkonzo ende nezindleko eziphansi zokulungiswa.
Ngaphezu kwalokho, amapayipi ensimbi enomoya we-astm astm a252 ayaziwa ngokusebenza kwayo okuhlukahlukene kanye nokufakwa kalula. Idizayini yabo eguquguqukayo ingenziwa kalula ukuze ihlangabezane nezidingo ezithile zephrojekthi, kuyilapho imvelo yabo engasindi yenza lula ukuphatha kanye nokuhamba kube lula. Lokhu kubenza kube yikhetho elingezelwe izindleko zezinhlelo zokusebenza ezahlukahlukene, ngoba zingafakwa ngokushesha nangendlela efanele, kunciphisa isikhathi sokusebenza kanye nesikhathi sokwakha.
Enye inzuzo yokusebenzisa i-ASTM A252 Spiral Welded Pipe ukuqina kwemvelo kwayo. Kwenziwe ngezinto ezisetshenziswayo, la mapayipi angasetshenziswa kabusha noma asuswe ekugcineni kwempilo yawo ewusizo, anciphise umthelela ophelele wezemvelo wokwakhiwa kwamapayipi nokulungisa. Ngokwengeziwe, izidingo zayo ezinde ezinde nezidingo zokulungiswa okuphansi zinomthelela kwingqalasizinda eqhubekayo futhi enobungane bemvelo.
Ekuphetheni, amapayipi ensimbi anomoya we-welded astm A252 anochungechunge lwezinzuzo ezenza kube yisinqumo sokuqala sokwakhiwa kwamapayipi. Amandla abo aphezulu, ukuqina, ukumelana kokugqwala, ukuguquguquka kokuqina, ukuqina kwezimo kanye nokuqina kwemvelo kubenza balungele izinhlelo ezahlukahlukene zezicelo ezahlukahlukene. Ngokukhetha la mapayipi, abathuthukisi bephrojekthi bangaqinisekisa uhlelo oluthembekile noluhlala isikhathi eside oluhlangabezana namazinga aphezulu kakhulu okusebenza.
