Uma kukhulunywa ngokwakha ubunjiniyela bomphakathi, ukukhetha kwezinto ezibonakalayo kubalulekile ekuqinisekiseni ubuqotho kanye nokuphila isikhathi eside kwesakhiwo. Into eyodwa enjalo eye yathola idumela eliqinile emboniniI-ASTM A252 Ibanga 2I-Pipe Piles. Le bhulogi izokwengeza imininingwane, izakhiwo, kanye nezidingo zokumaka ze-ASTM A252 ibanga 2 ukuthola ukuqonda okuphelele kokubaluleka kwayo kumaphrojekthi wokwakha.
Yini i-ASTM A252 Ibanga 2?
I-ASTM A252 iyincazelo ejwayelekile ye-Welded and Seamless yensimbi Tubular Piles Yezicelo zesisekelo. Ibanga lesi-2 lingelinye lamabanga amathathu achazwe kuleli Zinga, libanga iBanga lesi-1 libe yindawo ephansi nelibanga lesi-3 liphezulu kakhulu ngokwemibandela yokuthola amandla. I-ASTM A252 Ibanga 2 Izinqwaba ze-Tubeliselos zenzelwe ukuhlinzeka ngemali esele yamandla kanye ne-couctility, okwenza zilungele izinhlelo ezahlukahlukene, kufaka phakathi izisekelo ezijulile, izakhiwo zasolwandle nezinye izimo ezithwala umthwalo.
Izakhiwo ezibalulekile ze-ASTM A252 Ibanga 2 zifaka amandla aphansi wesivuno sama-psi angama-35,000 kanye namandla amancane ashubile angu-60,000 psi. Lezi zakhiwo ziqinisekisa ukuthi izinqwaba ziyakwazi ukumelana nemithwalo ebalulekile nezingcindezi, zizenze zilungele ukusetshenziswa ezindaweni eziyinselele.
I-ASTM A252 Ibanga 2 Amapayipi AMAKI AMAMAKI
Isici esibucayi se-ASTM A252 Ibanga lesi-2 liyisidingo sokumaka okufanele. Inqwaba ngayinye kufanele imakwe ngokucacile ukunikeza imininingwane ebalulekile ngomkhiqizo. Lokhu kuphawula kubalulekile ekulandeleleni, ukuqinisekiswa kwekhwalithi, kanye nokuhambisana namazinga embonini. Imininingwane elandelayo kumele ifakwe kumamaki:
I-1.Manierufar Igama noma uhlobo lomkhiqizo: Lokhu kukhomba umenzi wenqwaba, ukuqinisekisa ukuthi umsebenzisi angakwazi ukulandelela umkhiqizo ubuyiselwe emthonjeni.
Inombolo ye-2.Heat: Inombolo yokushisa iyisikhombi esiyingqayizivele esabelwe i-batch ethile yensimbi. Ivumela umsuka nezimpawu zezinto ezibonakalayo zilandelwa, okubalulekile ekulawulweni kwekhwalithi.
Inqubo ye-3.Manamunciker: Lokhu kukhombisa indlela esetshenziselwa ukukhiqiza inqwaba, noma ngabe ishiswe noma ingenamthungo. Ukuqonda inqubo yokukhiqiza kusiza ekuhloleni izici zokusebenza kwenqwaba.
Uhlobo oluhlangene lwe-4.Spiral: Uhlobo lwe-Spiral Joint olusetshenzisiwe kuipile lifakufanele imakwe, uma ikhona. Lolu lwazi lubalulekile ekuqondeni ubuqotho bezinqwaba zenqwaba.
Ububanzi be-5.Outer: ububanzi obungaphandle benqwaba kufanele bumakwe ngokucacile njengoba kuyisici esibucayi sokufaka nokubala kwemithwalo.
I-6.nominal odongeni ubukhulu: ukushuba udonga inqwaba kungenye indlela ebalulekile ethinta amandla ayo namandla afanele.
7.Yength nesisindo ngobude: ubude obuphelele nesisindo ubude benqwaba kumele kuchazwe. Lolu lwazi lubalulekile ekuhlelweni kwezinto nokufakwa.
8.Specification Igama nebanga: Ekugcineni, ukumaka kumele kufake igama elicacisiwe (ASTM A252) nebanga (Ibanga 2) ukuqinisekisa ukuhambisana namazinga ezimboni.
Ekuphetheni
I-ASTM A252 Ibanga 2 Amapayipi Amaphayiphu Alubalulekile Wokwakhiwa Kwanamuhla, ukuhlinzeka ngamandla adingekayo nokuqina kwezicelo ezahlukahlukene. Ukuqonda ukucaciswa kanye nezidingo zokumaka kubalulekile onjiniyela, osonkontileka, kanye nabaphathi bephrojekthi ukuqinisekisa ukuthi basebenzisa izinto ezifanele zamaphrojekthi abo. Ngokunamathela kulezi zindinganiso, imboni yezokwakha ingagcina imikhuba esezingeni eliphakeme futhi iqinisekise ukuphepha nokuphila isikhathi eside kwakhiwa kulawa malungu esisekelweni.
