Umbhobho wentsimbi odityanisiweyo: Isikhokelo esiBanzi sokuqinisekisa uQhagamshelwano olusebenzayo noluthembekileyo

Yazisa:

Kuwo wonke amashishini, imibhobho yentsimbi isetyenziswa kakhulu ukomelela, ukuqina, nokuguquguquka kwayo. Xa udibanisa iipayipi zensimbi, i-welding yindlela ekhethiweyo. I-Welding idala uqhagamshelo oluluqilima olunokumelana noxinzelelo oluphezulu, luyenza ibaluleke kakhulu kumacandelo afana nolwakhiwo, i-oyile kunye negesi, kunye nokuvelisa. Kule bhlog, siza kuntywila kukubaluleka kokuwelda kwemibhobho yentsimbi kwaye sinikeze isikhokelo esibanzi sokuqinisekisa uqhagamshelo olusebenzayo noluthembekileyo.

Ukuqulunqwa kwemichiza

Uvavanyo lweHydrostatic

Ubude bombhobho ngamnye buya kuvavanywa ngumenzi kuxinzelelo lwe-hydrostatic oluya kuvelisa eludongeni lombhobho uxinzelelo olungekho ngaphantsi kwama-60% obona buncinci buchaziweyo bamandla esivuno kwindawo yobushushu begumbi. Uxinzelelo luya kumiselwa ngolu nxaki lulandelayo:
P=2St/D

Ukwahluka okuvumelekileyo kubunzima kunye nemilinganiselo

Ubude bombhobho ngamnye buya kulinganiswa ngokwahlukileyo kwaye ubunzima bawo abuyi kwahluka ngaphezu kwe-10% ngaphezulu okanye i-5.5% phantsi kobunzima bethiyori, kubalwe kusetyenziswa ubude bayo kunye nobunzima bayo ngobude beyunithi.
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

Iyaphela

Iimfumba zemibhobho ziya kubonelelwa ngeziphelo ezicacileyo, kwaye i-burrs ekupheleni iya kususwa.
Xa isiphelo sombhobho esichazwe ukuba sibe yi-bevel siphela, i-angle iya kuba ngama-30 ukuya kuma-35 degrees

1. Qonda imibhobho yentsimbi:

 Imibhobho yentsimbiziza kwiindidi ezahlukeneyo zobukhulu, iimilo kunye nemathiriyeli, nganye ilungele usetyenziso oluthile. Ngokuqhelekileyo zenziwe nge-carbon steel, insimbi engenasici okanye i-alloy steel. Imibhobho yentsimbi yekhabhoni isetyenziswa kakhulu ngenxa yokufikeleleka kwayo namandla, ngelixa imibhobho yentsimbi engenasici inika ukuxhathisa okugqwesileyo kokutya. Kwiindawo eziphezulu zokushisa, iipayipi zensimbi ze-alloy zikhethwa. Ukuqonda iintlobo ezahlukeneyo zombhobho wensimbi kuya kunceda ukugqiba ukhetho olufanelekileyo lwe-welding.

2. Khetha inkqubo ye-welding:

Kukho iindlela ezahlukeneyo ze-welding ezisetyenziselwa ukujoyina umbhobho wensimbi, kubandakanywa i-arc welding, i-TIG (i-tungsten inert gas) i-welding, i-MIG (i-metal inert gas) i-welding, kunye ne-arc welding. Ukukhethwa kwenkqubo ye-welding kuxhomekeke kwizinto ezifana nohlobo lwentsimbi, ububanzi bombhobho, indawo ye-welding kunye noyilo oludibeneyo. Indlela nganye ineenzuzo kunye nemida, ngoko ke ukukhetha eyona nkqubo ifanelekileyo kwisicelo esifunwayo kubalulekile.

3. Lungisa umbhobho wentsimbi:

Ukulungiswa kombhobho ngokufanelekileyo ngaphambi kokuba i-welding ibaluleke kakhulu ekufezekiseni ukudibanisa okuqinileyo kunye nokuthembekileyo. Kubandakanya ukucoca umphezulu wombhobho ukususa nayiphi na i-rust, isikali okanye ukungcola. Oku kunokufezwa ngeendlela zokucoca ngoomatshini ezifana nokuxubha ucingo okanye ukugaya, okanye ngokusebenzisa izicoci zeekhemikhali. Ukongeza, ukuchasa isiphelo sombhobho kudala i-groove enemilo engu-V evumela ukungenwa ngcono kwezinto zokuzalisa, ngaloo ndlela iququzelela inkqubo ye-welding.

4. Itekhnoloji yokuwelda:

Ubuchule be-welding obusetyenzisiweyo buchaphazela kakhulu umgangatho wokudibanisa. Ngokuxhomekeke kwinkqubo ye-welding esetyenzisiweyo, iiparitha ezifanelekileyo ezifana ne-welding current, i-voltage, isantya sokuhamba kunye nokufakwa kokushisa kufuneka kugcinwe. Isakhono kunye namava e-welder nayo idlala indima ebalulekileyo ekufezekiseni i-weld elungileyo nengenasiphako. Ubuchwephesha obufana nokusebenza okufanelekileyo kwe-electrode, ukugcina i-arc ezinzile, kunye nokuqinisekisa ukuhamba kwegesi okwaneleyo kokukhusela kunokuncedisa ukunciphisa iziphene ezifana ne-porosity okanye ukungabikho kokudibanisa.

5. Uhlolo lwasemva kweweld:

Emva kokuba i-welding igqityiwe, kubalulekile ukuqhuba ukuhlolwa kwe-post-weld ukukhangela naziphi na iimpazamo okanye iimpazamo ezinokuphazamisa ingqibelelo yokudibanisa. Iindlela zovavanyo ezingonakalisiyo ezinje ngokuhlolwa okubonakalayo, uvavanyo lokungena kwedayi, uvavanyo lwemagnethi okanye uvavanyo lwe-ultrasonic lunokusetyenziswa. Olu hlolo lunceda ukuchonga iingxaki ezinokubakho kwaye kuqinisekiswe ukuba amajoyinti adityanisiweyo adibana neenkcukacha ezifunekayo.

Ukuququmbela:

 Umbhobho wentsimbi wokuWeldingkufuna ukuqwalaselwa ngononophelo kunye nokuphunyezwa okuchanekileyo ukuqinisekisa uqhagamshelwano olusebenzayo noluthembekileyo. Ngokuqonda iintlobo ezahlukeneyo zombhobho wentsimbi, ukukhetha inkqubo efanelekileyo yokudibanisa, ukulungiselela ngokupheleleyo umbhobho, usebenzisa iindlela ezifanelekileyo ze-welding, kunye nokuhlolwa kwe-post-weld, unokufezekisa i-welds enamandla kunye nekhwalithi ephezulu. Oku kunceda ukuphucula ukhuseleko, ukuthembeka kunye nobomi benkonzo yeepayipi zetsimbi kwizicelo ezahlukeneyo apho zingamacandelo abalulekileyo.
