IZIBONELELO ZOKUSETYENZISWA KOKUSETYENZISWA KWEXESHA LOKUGQIBELA LWE-SPEEL A252

IINGXAKI ZOKUSETYENZISWA KWEXESHA LOKUGQIBELA LWE-SPEEDS le-SPEE

Inkcazo emfutshane:

Xa imibhobho yokwakha imizi-mveliso yamashishini ahlukeneyo, ukhetho lwezinto ezibonakalayo lubalulekile. Imibhobho yentsimbi ye-Welfed, ngakumbi ezo zenziwa kwimigangatho ye-ASTM A252, iba lukhetho oludumileyo lwezicelo ezininzi ngenxa yezibonelelo ezininzi.

Iinkcukacha zemveliso

Iimpawu zeMveliso

Esona sibonelelo siphambili sokusebenzisa i-ASTM A252 I-SPIL yeSPIP yentsimbi ngamandla ayo kunye nokuqina. Le mibhobho inokumelana noxinzelelo oluphezulu kunye nemithwalo enzima, ibenza balungele ukuhanjiswa kweoyile kunye negesi, ukuthuthwa kwamanzi kunye nezicelo zesakhiwo. Inkqubo yokuphucula i-welding esetyenzisiweyo kwimveliso iqinisekisa ukuba unamandla kwaye uvumele umbhobho, uvumele umbhobho wokumelana neemeko ezinzima.

Uhlalutyo lwemveliso

Intsimbi ayisayi kuba ngaphezulu kwe-0.050% ye nkanlusi.

Umahluko ovumelekileyo kwimilinganiselo kunye nobungakanani

Ubude bomhungqe buya kuba bunzima ngokwahlukeneyo kwaye ubunzima bayo abuyi kuqhekeka ngaphezulu kwe-15% ngaphezulu okanye i-5% phantsi kobunzima bayo, babalwa besebenzisa ubude beyunithi nganye

Ububanzi bangaphandle abuyiwa ngaphezulu kwe- ± 1% ukusuka kwibala elichaziweyo ngaphandle kwe-diameter

Ubunzima bodonga nangayiphi na inqaku aliyi kuba ngaphezulu kwe-12,5% phantsi kobunzima obuchaziweyo

Ubude

Ubude obungakhethwanga okanye i-16 ukuya kwi-25ft (4.88 ukuya kwi-7.62m)

Ubude obuPhindwe kabini: Ngaphezulu kwe-35ft ukuya kwi-35ft (7.62 ukuya kwi-10.67m)

Ubude be-iyunifomu: ukwahluka okwaneleyo ± 1in

Ukongeza kumandla,Imibhobho yentsimbi ye-Welfmed Astm A252inika ukumelana nokunganyangeki. Oku kubaluleke kakhulu kwimibhobho eboniswe kwiimeko ezikhoyo zokusingqongileyo okanye izinto zoncedo. Ukukhusela okokugqibela kwezi pibhoyisi kuyaqhubeka ukonyusa ukunganyangeki kwabo, ukuqinisekisa ubomi obude beenkonzo kunye neendleko eziphantsi zolondolozo.

Ngaphaya koko, imibhobho yentsimbi ye-Welfmed A252 yaziwa ngokuqatha kwaye iphumelele ukufakela. Uyilo lwabo oluguqukayo lunokwenziwa ngokulula ukufezekisa iimfuno ezithile zeprojekthi, ngelixa indalo yabo elula yenza ukuphatha kunye nokuhamba kube lula. Oku kubenza babe luhambo oluneendleko zokusetyenziswa kwezicelo, njengoko zinokufakwa ngokukhawuleza nangokufanelekileyo, ukunciphisa ixesha lezabasebenzi neyakhiwe.

Elinye ithuba lokusebenzisa i-ASTM A252 I-Piel Pipe yeSpeel ye-Welfed syed kukuzinza kwayo kwindalo. Yenziwe ngezinto ezinokuphinda zisebenze, le mibhobho ingasetyenziswa kwakhona okanye ihlawuliswe xa kuphela ubomi babo oluluncedo, ukunciphisa ifuthe lendalo esingqongileyo yokwakhiwa kwepayiphu kunye nokulungiswa. Ukongeza, ubomi bayo obude kunye neemfuno zolondolozo olusezantsi zinegalelo kwiziseko zophuhliso ezizinzileyo nezinobuhlobo.

Ukuqukumbela, imibhobho yentsimbi ye-Welding Welded A252 inoluhlu lweenkonzo ezenza ukuba kuthathwe lukhetho lokuqala ukwakhiwa kwepayipile. Amandla abo aphezulu, ukuqina, ukumelana nokuziphatha koxinzelelo, ukungahambelani nokuzinza kwendalo kusenze bakufezekise iintlobo ezahlukeneyo kumashishini ahlukeneyo. Ngokukhetha le mibhobho, abaphuhlisi beeprojekthi banokuqinisekisa inkqubo yokuthintela i-piking ethembekileyo ehlangabezana neyona migangatho iphakamileyo kunye nemigangatho yokusebenza.
