Izinzuzo Zokusebenzisa I-SPIRALLY WELDED STEEL PIPES ASTM A252

Incazelo emfushane:

Lapho wakha amapayipi ezimboni ezihlukahlukene, ukukhethwa kwezinto ezibonakalayo kubalulekile. Ipayipi lensimbi elishiselwe ku-Spiral, ikakhulukazi lawo akhiqizwe kuzindinganiso ze-ASTM A252, seliyinto ethandwayo ezicelo eziningi ngenxa yezinzuzo zayo eziningi.

Thumela i-imeyili kithi

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Enye yezinzuzo eziyinhloko zokusebenzisa i-ASTM A252 spiral welded steel pipe amandla ayo aphezulu kanye nokuqina. Lawa mapayipi angakwazi ukumelana nokucindezela okukhulu kanye nemithwalo esindayo, okwenza kube ekahle ekudluliseni uwoyela negesi, ukuthutha emanzini kanye nezinhlelo zokusebenza zesakhiwo. Inqubo yokushisela okuvunguzayo esetshenziswa ekukhiqizeni iqinisekisa isibopho esiqinile futhi esilinganayo, okuvumela ipayipi ukuthi limelane nezindawo ezinokhahlo.

Impahla Mechanical

	Ibanga loku-1	Ibanga lesi-2	Ibanga lesi-3
Yield Point noma amandla esivuno, min, Mpa(PSI)	205(30 000)	240(35 000)	310(45 000)
Amandla e-tensile, min, Mpa(PSI)	345(50 000)	415(60 000)	455(66 0000)

Ukuhlaziywa Komkhiqizo

Insimbi akufanele ibe ngaphezu kuka-0.050% we-phosphorus.

Ukwehluka Okuvumelekile Kwesisindo Nobukhulu

Ubude benqwaba yamapayipi ngayinye buzokalwa ngokuhlukana futhi isisindo sawo angeke sihluke ngaphezu kuka-15% ngaphezulu noma u-5% ngaphansi kwesisindo salo esicatshangelwayo, kubalwe kusetshenziswa ubude balo nesisindo salo ngobude beyunithi ngayinye.

Idayamitha yangaphandle akumele ihluke ngaphezu kuka-±1% ukusuka kububanzi obukhethekile obushiwo bangaphandle

Ukujiya kodonga kunoma iyiphi indawo akufanele kube ngaphezu kuka-12.5% ngaphansi kogqinsi olushiwo

Ubude

Ubude obungahleliwe obubodwa: 16 kuya ku-25ft(4.88 kuya ku-7.62m)

Ubude obuphindwe kabili obungahleliwe: ngaphezulu kwama-25ft kuya ku-35ft(7.62 kuya ku-10.67m)

Ubude obufanayo: ukuhluka okuvumelekile ±1in

Ngaphezu kwamandla,amapayipi ensimbi ashiselwe ngokuvunguza ASTM A252inikeza ukumelana nokugqwala okuhle kakhulu. Lokhu kubaluleke kakhulu kumapayipi achayeke ezimeni ezinzima zemvelo noma izinto ezonakalisayo. Ukuvikela kulawa mapayipi kuthuthukisa ngokwengeziwe ukumelana nokugqwala, kuqinisekisa impilo ende yesevisi kanye nezindleko zokunakekela eziphansi.

Ngaphezu kwalokho, amapayipi ensimbi ashiselwe ngokuvunguza i-ASTM A252 yaziwa ngokuguquguquka kwawo kanye nokufaka kalula. Idizayini yabo eguquguqukayo ingenziwa ngokwezifiso kalula ukuze ihlangabezane nezidingo ezithile zephrojekthi, kuyilapho imvelo yazo engasindi yenza ukubamba nokuthutha kube lula. Lokhu kubenza babe ukukhetha okungabizi kakhulu kwezinhlelo zokusebenza ezihlukahlukene, njengoba zingafakwa ngokushesha nangempumelelo, ukunciphisa isikhathi sokusebenza nesokwakha.

Enye inzuzo yokusebenzisa i-ASTM A252 spiral welded steel pipe ukusimama kwayo kwemvelo. Enziwe ngezinto ezigaywa kabusha, lawa mapayipi angasetshenziswa kabusha noma aphinde asetshenziswe ekupheleni kwempilo yawo ewusizo, okunciphisa umthelela ophelele wemvelo wokwakhiwa nokugcinwa kwamapayipi. Ukwengeza, ubude bayo besikhathi eside kanye nezidingo zokunakekelwa okuphansi zifaka isandla engqalasizinda esimeme futhi engayingeni imvelo.

Sengiphetha, amapayipi ensimbi ashiselwe ngomoya we-ASTM A252 anochungechunge lwezinzuzo ezenza kube yisinqumo sokuqala sokwakhiwa kwamapayipi. Amandla azo aphezulu, ukuqina, ukumelana nokugqwala, ukuguquguquka kwezinto ezihlukahlukene kanye nokusimama kwemvelo kuwenza afanelekele ukusetshenziswa okuhlukahlukene ezimbonini ezahlukene. Ngokukhetha lawa mapayipi, abathuthukisi bephrojekthi bangaqinisekisa uhlelo lwamapayipi oluthembekile futhi oluhlala isikhathi eside oluhlangabezana nekhwalithi ephezulu kanye nezindinganiso zokusebenza.
