ASTM A252 iyilwimi elikhethwe kumoya wokuthenga ngephuphe phuphe lesikhephe sesiqephu semakhwebhu. Ndithola emuva kwezinye ezifana namanye amaninzi, iindlebe zemakhwebhu lemfuphi olungulumelelwa ngaphandle komhlaba njengamandla okufundekileyo kubuildings, izibridge noma amasimu esingisekelo. Kukhona ngakho umthombo omkhulu lokusebenza lokuhlala ukugcina ukuze kube kusenzo nokutholakalayo kufuneka kuhlolwe kumakhwebhu. Zonke izinto ezifanele nezindawo zazigcinwe ngokuthi ASTM yabelana nge-A252 steel pipe? Yaziqinisekisa ukuthi ubani obafuna ukuba ngaphansi kanjani amaphuphe, kunye nokuba bayenza ngendawo yokubuyela ngokupheleleyo ngokusebenza. Kuningi lokuncedwa ukuthi ubani obafuna ukuba ngaphezulu kanjani iphuphe; kunye nokuthi kusenziwe ngakho kunini kunye nokuba kufanele kungakho.
Ngakho, isigaba esingcedwa kakhulu ngokuthi lokhu kushayamana ukufaka umsebenzi omkhulu okulandelayo kunye nokuthi ngasinye lesi simanzelo sikuhlala ngomnyaka, uhambo olunqanambili lwezinkathalo zakho zishayamana ukuba amagreyidi akhule. Amaphayipha westeel ezilandelwe ngeASTM A252 kufuneka besebe bonke obuchaze iziphumo emikhulu njengalokhu angithetha ukusetyenziswa ephakathi kwebhejane. Izindlela ezilindeleyo zisetshenziswa ngenkinga yokugcina amaxhobo amakhulu, ngoba imibuzwana engaphezulu kufuneka ifakwe. Lokuhle kukho ukuthi bayasebenza ukukhupha inani elikhulu lemfolofo futhi angabhekisele khona... okanye azikhethe izinto zazo ngonyaka zeminyaka. Ngakho ke, lokhu lingezwelwa ngokuthi ingxenye yokuqala yebhokisi yinhloso yayo yenza ukuthi ufunde ukuthi ubungako obungcono kakhulu lokusebenza lokulandelwa.
Iphakathi kakhulu ukuba amalendawo amanqaku weesi ayikho amaphutha kunye nokukhetha ukuba amaphrojekthi amahle angqalekanga ngokusebenzela iindlela ezikhoyo zokungena ngeASTM A252. Ngokubanzi, lokhu luhlala kwi-standarde, luchazwe amaphrojekthi kunye neziphumo ezinentsha ezinokuqinisekisa amaphipha okulandelwayo, ezifunyanwa kusekcancane la 6.2 leISO15609-1. Ukuphumelela kwesibonelo sokugcina kumashova asenziwa ukuba bazingama ukusetyenziswa kwezindlu kunye nezincwadi ezingamandla, okanye ukwenza isiphumo esisodwa xa zihlola emigodi. Sifuna ukuba loluhlobo lwesixhobo lisetshenziswa ukuba kuhlanganise amasimu amahlula kunye namasimu amadliwayo.
Ngokusha kwiqhutywa lwenqanawe, kufuneka ukhethise amandla ehlangene neASTM A252 pipe pile ngenxa yalokho uzoba ukuthi umsebenzi wakho uvumele kuqala. Ukuphinda ukhetho olungapheli lokhu kuzobheka ngendlela nesikhatsi esidingiwe yomsebenzi wakho. Kuna izicwangciso eziningi zezilondolozi le-ASTM A252, okuyingxenye yeyiphi elisetyenziswa kumgama omtsha. Ngamagama amahlukeni akukho nokuthi amasibonelo asikusukela, i-ASTM A252 Grade 3 lingayaziyo lokulandelana. Ngi-ASTM A642 Grade 3 usuka kakhulu kunye nokusebenza ngokuhlawulwa kumazibuko ezingasiza, xa ke i-ASTMA639 grade2 lingayaziyo yokugcina kwiqhutywa lenyoni nelamandla amahlukeni amacabango amanqaku amanqanekayo.
Kusindwe i-ASTM A252 Steel Pipe Piles okungakwazi ukulandela izicatshulwa ezininzi ezikhethiwe ngokuboniso kwi-building foundations, structure construction kunye ne-retaining walls phakathi kwezinhlobo ezintsha noma izinga lembuzo. Ukuphakamisana kunye nekuphakamisana kwesi-steel pipe piles kulandelana nokuthi bengxenye ekunene engalawulwa amaphutha angazo kanye namabhabha. Ngakho ke, i-steel pipes zizibuyiselwa kunye neziqhamuka lokusebenza ukuze kube ngenkinga lomhlaba. Iziphutha ezinikezeli zingazama ukuba abasebenzisi baziphatha indlela yokuhlola kwezindlela ezilindeleyo ezidlule.
Ibhizinisi yakho iyahlukile ngeminyaka engaphezulu kwaloo lapho luchaseneyo lokuhlola isitayili sesteel kunye nokufakelwa kwisebe eliphambili. Nalo ngephrofayela labasebenzi sesiqhelo lesifunda phambi kokuthi usetyenziswa, kunye nokuthi uzobuya nokuthatha izindaba ezimfanele kunye nokuthuthukisa. Ukubuyela kuhluke ukuthi ulenziwe imali ekunene!
Kune esihle kakhulu umphathalentsi wethu wesikrini somsebenzi we-astm a252, ngenxa yomthombo omkhulu wokuthatha amanqaku, izibhalo eziphawuli nokuseva esikhatsi sokuqala. Kune umphathalentsi wesayithi esihle lokuhlola imicimbi yesikhethekile 24 izinsuku zehlula ukukholela izicatshulwa, izicelenza, iziphumo nezimali. Siyiqinisekisi elikhulu lokushintsha ukuze sihlale ngokupheli kakhulu njengesiphamende sokugcina
Siyakwazi ukuthatha iindlela zesitshalo se-Amerika/Britain/Australia H-beams nesitshalo sesi-Japan steel astm a252 futhi siyakwenza izinhlelo ezidingekayo njenge-punching kunye ncwadi. Ngonyaka odlule, amanxoxo akho abeke Africa Australia, South America, Southeast Asia, Afrika, Middle East kunye namanje amasendaweni
Iphrojekthi eliphakamisiwe ngaphambi kokuthumela. Ukuphakamisekiswa kuvunyelwe. Iziphrojekthi zokugcina ziyizikhwama ezidingekileyo zomlomo astm a252/SSAW/LSAW/ galvanized/rectangular pipe/seamless pipe/stainless steel pipe), amandla (isithathu sasendle, isithathu sesikhombisa, isithathu se-Australia H-beam steel), amandla, Angle steel, flat steel, steel sheet piles, izikhwama eziningi lestele ngezinye iindlela ezinomsindo, amabhopho, strip steel, scaffolding, steel wire, amathswa, nokusha.
