Ukukhetha lokungangekonki ipayipi Lensimbi Engagqwali kunesidingo esikrholwayo ekukhethweni kwebhola yesilindelo sokusebenza kwakho, ubude bephrojekthi, ubude bomthwalo, nokutholakala kwezimali. Ukukhetha uhlobo lwesilindelo sesilindelo sinesidingo esikrholwayo emandleni ekulungiselela ukuchithwa, amathiphu okumeleli, nesimo sokusebenza ngemizamo yamaphakade. Leli guida elelithile kuzokusiza ukulondoloza umhlaba ophuthelene wokukhetha isilindelo sesilindelo, ukuqinisekisa ukuthi uthathe izinqumo ezibonakalayo kumasebenzi akho ebandleni.
Isimo sebengqoleni sisebenza kakhulu ekubekeni inqanawa eyisisekelo yomgwa we-stainless steel. Izimo ezahlukene zibonakala ngemiphumela engahle, kusukela emthintfweni wamazulu kuze kube kusebenziswa kumahluko. Isimo sendawo yesilwana, umzekelo, ubenza ukuthi kudingekwe ukulungiswa okuphansi kwesimo sokuhlaba ngoba kugcinwa kuhlaba ngokudlula. Izigodi zezimali zingadinga ukulungiswa kumahluko ahlanzekile noma kumahluko wempumelelo.
Xa uvavanya izinhloso zezimo, qaphela ukuthi kukhona izimboni zokuhlaba, amahlotyana empumelelo, nokuhlaba kwizimboni ezahlukene. Inqanawa yomgwa we-stainless steel eziyi-316 ibonisa ukulungiswa okuphansi kokuhlaba kungeyokuthi i-Grade 304, lokhu kuyakho kakhulu endaweni yesilwana nezimali. Ukunyuswa kwe-molybdenum eziyi-Grade 316 kuyakhathaza ukulungiswa kwayo ekuphileni nokuhlaba kwamadoda.
Amathempurhijha nezimo zodonsela kuyakhazimula ukukhethwa kweziphati ze-stainless steel. Izigano ezingadinga amathempurhijha aphezulu kudinga izigano eziquqashisa ubunzima bazo nobulahleli bomphini emathempurhijheni aphezulu. Izigano zeAustenitic njenge-304L ne-316L zibonisa imfaneleko emihle kumathempurhijha aphezulu ngemuva wokuba ziqinisekisa ubunjingiliwa phansi kwemithempurhijha engaphansi komthambeka.
Kumele kugcinwe isimo sedonsela ukuqinisekisa ukuthi iphati ye-stainless steel ekhethiwe ingahlawulela ngempilo izidingo zomthombo. Ubude bezibhali nezinombolo zosikhwama zidala indima eyakhiweka ekwakhiweni kodonsela. Abasebenzi basejinjini kumele bafundeni ubude bezibhali okudingekayo ngokushiya phantsi idizayini yodonsela, amathempurhijha, nezinhlobo zokuphepha okufanele kuzisetshenziselwa.
Iziphawu zomshilo zezikhala zepayiphi yesithili esiphathelene sikhulu, zihlukanisa ukusebenza kwazo kumsebenzi wonke. I-Tensile strength, yield strength, ne-hardness yizinkinga ezibalulekileyo ekubaleni ngazo. I-Duplex stainless steel pipes inemiphumela eliphezulu kungeza kwe-austenitic grades, lokhu kuyakwenzela ukuthi ibe yisizo sezingcingo eziphakeme ngaphandle kokuphila okungcono, ngelokho kusabalasele kuzidingo oluphakeme.
Faka phakathi impact yokwephukela kwi-siphawu zomshilo, ngoba izilinganiso ze-strength zilandela ukuncipha emakhaya aphezulu. Kunezikhala ezimbala elinikeza imiphumela engcono emakhaya aphezulu, kodwa ezinye ziyashaya kuzidingo ze-cryogenic. Inketho yokukhetha kufuneka ibonelele lezi zihloko ukuqinisekisa ukusebenza okuhle kuyo yonke indlela yomphakathi.
Ukukhulula kwekuhlaka nokufakwa kungaba nobubi obungcono emali nezinsuku zomshado. Ezinye izinhlobo zezinja zezinkunkuma ezinzulu zinokwenzeka ngokuphindwe, kodwa ezinye kuzodinga ukuphatha okuthile ngexesha lokugaya noma ukudala. Izinhlobo zase-Austenitic zingaba nomlando omuhle wokunqamula nokudalwa, futhi kungcono ukuthi zibekwe phambi kwemisebenzi engcono.
Cinga imithodi yokuhlaka efunwayo, kufaka phakathi izinhilo zokunqamula, izidingo zokugaya, nezidingo zokulungisa isiphelo. Kudingeka ukuthi ukukhetha kwisinhlobo kubalise amathemu okumelana nokuhlaka ngendlela efanelekile ukuze kuthuthukise inzuzo yokuqeqesha nokuthulaselwa komthelelo.
Nakuba izindleko zokuthola imithwalo kusuku lokuqala zihlaza ukukhethwa kweziphathe steyinishi, ukuzinquma kuphela kwiindreko yokuthengisa kungahle kube yizindleko eziningi ngomnyaka ophezulu. Cinga izindleko zomkhawulo wokuphila, kufakwe phakathi ukufakwa, ukulungiswa, nezindleko zokubuyisela uma kudingeka. Iziphathe ze-stainless steel ezingaphezulu zingadinga izindleko ezikhulu kodwa zinikeza inhlaka ephezulu ngokuphila kwazo kanye nokuncipha kwezindleko zokulungiswa.
Shayela izindleko zezinhlobo ezahlukene ngokuhlatshelana nendlela osethembekileyo. Faka phakathi izindleko ezinconywayo zokumisa komthetho, ukulungiswa, kanye nokubuyiselwa xa usihlonipha. Ngamanye amaxesha, ukuthenge siphathe se-stainless steel esingaphezulu kusuku lokuqala kunokunika ukunciphisa kwezindleko ngexesha lonke lwesiqu.
Iingcinga ezahlukeneyo ze-stainless steel pipe zidinga iindlela ezahlukileyo zokuphatha nokunikezela iinkcukacha ezahlukeneyo zokubaluleka. Cinga ngendawo epholileyo yomgca osetshenziswayo ukuze uvavanywe nokuphathwa kwezinyathelo. Ezinye iindlela mhlawumbi zinika umbono wokukhetha umxholo ophezulu ukuze kuphazamiseke ukuphatha okudingayo kwaye kuvukele ubunzima bomthombo.
Izigongo zokuvavanya nezokuphatha zimele ukulungiswa ngokulingana nomxholo obhekisiweyo nemithwalo yentsekelo. Ukukhetha kwempilo enempilo kungakhusela kakhulu ukuphindaphinda nokuba kukuphi okufunekayo kokuphatha, kuthumela ekuvuseleleni kwezenzo kanye nokunciphisa izindleko zomthombo wokuphila.
Iimithetho kunye nemigaqo yendalo yendalo zibaluleka imfundo apho amandla aphantsi aziphumla iingcinga eziphansi zokukhetha stainless steel pipe. Iimigaqo ezifundiswa ngokubanzi zi-ASTM, ASME, kunye ne-EN. Qinisekani ukuba iingcinga ezikhethiweyo zihlambuluka zonke iimfuno ezihlaleleyo kunye neemfuno zokubhabha kwiindlela zakho ezithile.
Izidingo zodokumenti ziyavaryinga ngasikhala nasekusebenzisweni. Qiniseza ukuba une amabhukhithi abalulekile nokubhalisa iziphumo zokuhlola ukuze ubonise ukuthi uyaphilaphila kuzimiso ezihambelana. Leli dokhumenti libaluleke kakhulu ekunikelweni iqiniso lokuhlelekisa ubumnandi nezimali.
Sebenzisa izindlela ezifanelekileyo zokuhlelekisa ubumnandi ngexesha lokukhetha nokuthenga. Qiniseza i-sertifikethi yomongo, phakela imizamo efunwayo, qiniseza ukuba umongo uyafakwa ngendlela efanelekileyo. Gcina ukhondo olufunwayo kusebenziswako, njengehlola ngamanzi, hlola ngaphandle kokugcina, noma uhlelo lwemithi.
Vula izimiso eziphambili nezimiso zokuvikela xa uthenga iphayipi yesitisilayini. Ukusebenzana nabasebenzi abathembekile abaqhubeka nokuphatha izinhlelo ezibangela ubumnandi obugcwele kunceda ukuthi ubeke ubumnandi nesivumelwano sobumnandi.
Iphayipi yesithili esingcwele se-Grade 316 isafakwa i-molybdenum, okunikeza ukukhululwa kakhulu kwe-corrosion kungekwa kwe-Grade 304. Nakuba izigaba ezimbili zinikeza ukukhululwa kwe-corrosion ngokujulile, i-316 inakekela kangcono emazingeni ephathekayo nemisebenzi yemiphambano yezilimi. I-Grade 316 njalo inomthelelo obanzi kodwa inikeza imfaneleko ephelele kuzindiza ezidingekayo.
Ukufunda kwesilinganiso sobude bezibuko kufaka phakathi ukubala izidingo zeqhuba, izimo zempilo, nezinkinga zokuphepha ngokwemikoronto yokudizaina eyaziwayo. Qiniseka ukuthi uqwalasele indawo eqhubekayo nangaphandle kwebhodi. Ukuxhumana nabalinganiswa abaqashisayo noma ukusebenzisa izindlela ezibonakalayo zokubala ku-ASME noma nezinye izinhlobo zezinhloso kusinika uhlelo olufanele.
Mqaphele ukusebenzisa iphayipi yesilika se-stainless steel xa izixhobo zidinga ubumfihlakalo obungaphezulu ngokuhambelana nesimo esihle sokukhulula kakhulu. Iziphawu ezifanayo kufuphi kuzo zingaphandle kwezixhobo ezingaphezulu, iingcinga ze-structural, nezimo ezingaqeshwa ngachloride. Iinkcubeko ze-duplex zanika izisombululo eziphawulayo kwiizixhobo ezikhathazekileyo ngokuthulasela ubude bephayipi ethengiselwe ngelishwa elisebenza ngendlela efanelekileyo.
