Izindaba - Amapuleti Ensimbi Ashisayo Agoqekile e-ASTM A572 Ibanga 50 vs ASTM A992: Amandla, Ukuguquguquka, kanye Nezicelo Zanamuhla

Ezweni lobunjiniyela bezakhiwo zanamuhla kanye nokwakhiwa, ukukhetha insimbi akuvamile neze. Amapuleti amabili ensimbi ashiswayo avame ukucaciswa kakhulu—Ibanga lama-50 le-ASTM A572futhiI-ASTM A992—bazimise njengezindinganiso zemboni zamaphrojekthi adinga ibhalansi yamandla, ukuguquguquka, kanye nokuthembeka.

Umkhiqizi Omkhulu Weqembu Lensimbi Yasebukhosini Yamashidi Namapuleti Ensimbi Asezingeni Eliphezulu

Ipuleti Lensimbi Eligoqiwe Elishisayo le-ASTM A572 Grade 50iyipuleti lensimbi elinamandla aphezulu, elingena-alloy ephansi elisetshenziswa kabanzi ekusetshenzisweni kwesakhiwo, amabhuloho, kanye nokwakhiwa okuvamile. Amandla ayo okukhiqiza angama-50 ksi (345 MPa) kanye namandla okudonsa asukela ku-65–80 ksi (450–550 MPa)yenze kube ukukhetha okuguquguqukayo konjiniyela abafuna kokubili ukusebenza kahle kanye nokusebenza kahle kwezindleko. Ngaphezu kwalokho, i-ASTM A572 Grade 50 ibonisa ukushibilika okuhle kakhulu kanye nokwakheka kahle, okuvumela ukwenziwa okuyinkimbinkimbi ngaphandle kokubeka engcupheni ubuqotho bensimbi. Inhlanganisela yamandla, ukuqina, kanye nokumelana nokugqwala kuyenza ifaneleke ezakhiweni ezisindayo, okuhlanganisa izakhiwo zezimboni, amapulatifomu emishini, kanye nengqalasizinda yezokuthutha.

Ngokolunye uhlangothi,Ipuleti Lensimbi Eligoqiwe Elishisayo le-ASTM A992Sekuyizinto ezithandwa kakhulu zezimo zesakhiwo ezine-flange ebanzi, ikakhulukazi eNyakatho Melika. Ekuqaleni yaklanywa ukuze ithathe indawo ye-ASTM A36 ngezimo zesakhiwo, i-A992 inikeza amandla okukhiqiza okungenani angu-50 ksi (345 MPa), kanye nokuqina okuphezulu kanye nokuguquguquka, okwenza ibe yindawo ekahle yezakhiwo ezingamelani nokuzamazama komhlaba. Insimbi ye-A992 iphinde ibe nokugobeka okuthuthukisiwe kanye nokushibilika, okuvumela abakhiqizi bezakhiwo ukuthi bahlangabezane nezimfuneko zomklamo eziqinile ngempumelelo. Ukwamukelwa kwayo kabanzi ezakhiweni zezentengiselwano, amabhuloho, kanye nezinhlaka zezimboni kuwubufakazi bokusebenza kwayo okuphezulu kokubili ezimweni zokulayisha ezimile nezishintshashintshayo.

Nakuba zombili izinhlobo zensimbi zinamandla afanayo okukhiqiza, azikwazi ukushintshaniswa kuzo zonke izinhlelo zokusebenza. I-ASTM A572 Grade 50 ivame ukukhethwa ukuze kusetshenziswe amapuleti adinga ukusika ngokwezifiso, ukugaya, noma ukumelana nokuguguleka okunzima, kanti i-ASTM A992 ilungiselelwe izimo zesakhiwo ezifanaImishayo ye-IfuthiImisebe ye-H, lapho ukuzinza okuphezulu kwezinhlangothi kanye nokuguquguquka ngaphansi komthwalo kubalulekile khona. Ukukhetha insimbi efanele kuhilela ukucabangela ngokucophelela izidingo zomthwalo wephrojekthi, izindlela zokukhiqiza, kanye nezimo zemvelo.

Ngaphandle kwezakhiwo zabo zemishini, zombiliAmapuleti ensimbi e-ASTM A572 Grade 50futhiAmapuleti ensimbi e-ASTM A992Kukhiqizwa ngezinqubo ezithuthukisiwe zokugoqa ezishisayo. Ukugoqa okushisayo kunikeza ukujiya okufanayo kanye nokuqedwa kobuso obubushelelezi ngenkathi kuthuthukiswa isakhiwo sangaphakathi sensimbi. Izakhiwo zokukhiqiza zanamuhla zisebenzisa izigayo zokugoqa ezilawulwa yikhompyutha ukuqinisekisa ukubekezelelana okunembile kobukhulu, okwenza lawa mapuleti ahambisane namaphrojekthi okwakha nobunjiniyela anembe kakhulu.

Ngokombono ongokoqobo, onjiniyela, abakhiqizi, kanye nabaphathi bephrojekthi bavame ukucabanga ngokuthembeka kweketanga lokuhlinzeka kanye nokutholakala lapho becacisa amazinga ensimbi. Abaphakeli abaphambili bahlinzeka ngala mapuleti ngobubanzi, ububanzi, nobude obuhlukahlukene ukuze kuhlangatshezwane nemiklamo yesakhiwo eyenziwe ngokwezifiso. Ngaphezu kwalokho, abakhiqizi abaningi banikeza izinhlangano ezisikiwe ngobukhulu, ezibholiwe ngaphambilini, noma ezihlanganisiwe, kunciphisa umsebenzi endaweni futhi kusheshiswe isikhathi sephrojekthi.

Ekuphetheni,Ibanga lama-50 le-ASTM A572amapuleti ensimbi ashisiwe ashisayofuthiAmapuleti ensimbi ashisiwe e-ASTM A992ziyaqhubeka nokuba umgogodla wobunjiniyela bezakhiwo besimanje. Ngayinye inikeza inhlanganisela eyingqayizivele yamandla, ukuguquguquka, kanye nokusebenza kahle, eyenzelwe izidingo ezithile zokwakha kanye nokukhiqiza. Kungakhathaliseki ukuthi kusetshenziswa emabhulohweni, ezakhiweni zezentengiselwano, noma ezisekelweni zezimboni, ukukhetha izinga lensimbi elifanele kuqinisekisa ukuphepha, ukuqina, kanye nobuqotho besakhiwo besikhathi eside. Embonini lapho ukunemba nokusebenza kubalulekile, lawa mapuleti amabili ensimbi ahlala ethembekile kunjiniyela emhlabeni jikelele.
