Iinkcukacha zeMveliso

Iithegi zeMveliso

Enye yeenzuzo eziphambili zokusebenzisa i-ASTM A252 spiral welded steel pipe ngamandla ayo aphezulu kunye nokuqina. Le mibhobho inokumelana noxinzelelo oluphezulu kunye nemithwalo enzima, eyenza ibe yinto efanelekileyo yokuhanjiswa kweoli kunye negesi, ukuthuthwa kwamanzi kunye nezicelo zesakhiwo. Inkqubo ye-spiral welding esetyenziswa kwimveliso iqinisekisa ukuqina kunye nokubambana, ukuvumela umbhobho ukuba umelane neendawo ezingqongileyo.

Uhlalutyo lweMveliso

Intsimbi ayiyi kuba ngaphezu kwe-0.050% ye-phosphorus.

Ukwahluka okuvumelekileyo kubunzima kunye nemilinganiselo

Ubude bombhobho ngamnye buya kulinganiswa ngokwahlukeneyo kwaye ubunzima bayo abuyi kwahluka ngaphezu kwe-15% ngaphezulu okanye i-5% phantsi kobunzima bayo bethiyori, kubalwe kusetyenziswa ubude bayo kunye nobunzima bayo ngeyunithi yobude.

Idayamitha yangaphandle ayisayi kwahluka ngaphezu kwe-±1% ukusuka kwidayamitha yangaphandle echaziweyo

Ubunzima bodonga nakweyiphi na indawo abuyi kuba ngaphezu kwe-12.5% phantsi kobukhulu bodonga oluchaziweyo

Ubude

Ubude obubodwa obungakhethiyo: 16 ukuya ku-25ft (4.88 ukuya ku-7.62m)

Ubude obuphindwe kabini obungenamkhethe: ngaphezulu kwe-25ft ukuya kwi-35ft (7.62 ukuya kwi-10.67m)

Ubude obufanayo: ukwahluka okuvumelekileyo ±1in

Ngaphandle kwamandla,imibhobho yentsimbi edityanisiweyo ngokuvunguzayo ASTM A252inikeza ukuxhathisa okugqwesileyo kokutya. Oku kubaluleke kakhulu kwimibhobho evezwe kwiimeko ezinzima zokusingqongileyo okanye izinto ezinobungozi. Ukugquma okukhuselekileyo kule mibhobho kwandisa ngakumbi ukuxhathisa ukubola, ukuqinisekisa ubomi obude benkonzo kunye neendleko zokugcinwa okuphantsi.

Ngaphaya koko, imibhobho yentsimbi edityanisiweyo nge-spiral ye-ASTM A252 yaziwa ngokuguquguquka kwayo kunye nokulula ukufakela. Uyilo lwabo oluguquguqukayo lunokwenziwa lula ukuhlangabezana neemfuno ezithile zeprojekthi, ngelixa indalo yabo elula yenza ukuphatha kunye nokuthutha kube lula. Oku kubenza babe yindleko-esebenzayo yokukhetha izicelo ezahlukeneyo, njengoko zinokufakwa ngokukhawuleza nangokufanelekileyo, ukunciphisa umsebenzi kunye nexesha lokwakha.

Enye inzuzo yokusebenzisa i-ASTM A252 spiral welded steel pipe kukuzinza kwayo kokusingqongileyo. Yenziwe kwizinto ezinokuphinda zisetyenziswe, le mibhobho ingaphinda isetyenziswe okanye isetyenziswe kwakhona ekupheleni kobomi bayo obuncedo, ukunciphisa impembelelo yokusingqongileyo yokwakhiwa kunye nokugcinwa kwemibhobho. Ukongeza, ubomi bayo obude kunye neemfuno zokugcinwa okuphantsi zinegalelo kwiziseko ezingundoqo ezizinzileyo nezingakhathaleli indalo esingqongileyo.

Ukuqukumbela, imibhobho yentsimbi edityanisiweyo nge-spiral ye-ASTM A252 inoluhlu lweenzuzo ezenza kube lukhetho lokuqala lokwakhiwa kwemibhobho. Amandla abo aphezulu, ukuqina, ukuxhathisa umhlwa, ukuguquguquka kunye nokuzinza kwendalo kubenza bafanelekele ngokufanelekileyo usetyenziso oluhlukeneyo kumashishini ahlukeneyo. Ngokukhetha le mibhobho, abaphuhlisi beprojekthi banokuqinisekisa inkqubo yepayipi ethembekileyo nehlala ixesha elide ehlangabezana nomgangatho ophezulu kunye nemigangatho yokusebenza.
