I-Welded vs Seamless Steel Pipes: IiPros, Cons, kunye naMatyala oSetyenziso oluGqwesileyo

Ukukhetha phakathi imibhobho edityanisiweyo kunye nemijelo yentsimbi engenamthungo imele esinye sezona zigqibo zibaluleke kakhulu kuyilo lwenkqubo yemibhobho yoshishino, ifuthe elithe ngqo ekusebenzeni, ukuphumelela kweendleko, kunye nokuthembeka kokusebenza. Amashaneli adityanisiweyo anikezela ngokhetho olungenakuphikiswa ngokwemiqathango yokuthathwa kochaso kunye nokufikeleleka, ngelixa iinketho ezihambelanayo zinika ukuvavanya ubunzima obuphambili kunye nokuhambelana okusisiseko. Ukuqonda ukuchasana okuphambili phakathi kwezi zicwangciso zobuchule bokwenza imibhobho kusisiseko kwiinjineli, ukwandisa abaphathi, kunye neengcali zokufumana kufuneka zilungelelanise iimfuno zobugcisa kunye nokulinganiselwa kwebhajethi. Olu phando lubanzi luhlalutya iifom zokuyila, iimpawu zokwenziwa, kunye nezicelo ezifanelekileyo zohlobo lombhobho ngamnye, ukuxhobisa ukuthathwa kwezigqibo ezifundileyo kwizicelo zoomatshini ezahlukeneyo kwi-oyile negesi, ukuphatha imichiza, ixesha lolawulo, kunye namacandelo okwakha asisiseko.

IiNkqubo zokuVelisa kunye neempawu zeZakhiwo

Iindlela zeMveliso zemibhobho edityanisiweyo kunye noLawulo loMgangatho

Iziteshi ezidibeneyo zenziwe ngeefom ezimbalwa eziphambili, kunye ne-Electric Resistance Welding (RW) kunye ne-Submerged Bend Welding (SAW) yizona zicwangciso eziphambili kwizicelo zoomatshini. Umqheba we-ERW uquka ukubumba imicu yentsimbi ibe yimilo engqukuva kunye negongxobo kunye ne-welding crease usebenzisa i-high-frequency current yombane, ukwenza indawo edityanisiweyo edibanisa isinyithi kwinqanaba leathom. Le ndlela yokwenza ivumela ulawulo oluchanekileyo kunye nobukhulu besahluli esizinzileyo kubo bonke ubude bombhobho. Ukunciphisa i-Welded Channels amava amaqhinga okulawula umgangatho ngokucokisekileyo, ukubala uvavanyo lwe-ultrasonic lwe-weld crease, uvavanyo lobunzima be-hydrostatic, kunye nokuqinisekiswa kwe-dimensional ukuqinisekisa ukuthotyelwa kwemilinganiselo yehlabathi jikelele njenge-ASTM, i-API, kunye neenkcukacha ze-ASME. Imeko elawulwayo yokuyila ixhobisa abavelisi ukuba bagcine imilinganiselo engqongqo yomgangatho ngelixa bephumeza imiqulu yokuvelisa enexabiso eliphantsi eyenza ezi jelo zibe nomtsalane ngokwezimali kwiiprojekthi ezinkulu.

Ukwenziwa kweMibhobho engenamthungo kunye neePropati zeMathiriyeli

Imijelo yentsimbi engenamthungo iveliswa ngokubhoboza okutshisayo kunye neenkqubo zokuqengqeleka ezisusa imfuno ye-welds ye-longitudinal, okukhokelela kwiimpawu zezinto ezifanayo kulo lonke icandelo lombhobho, ngokungafaniyo. imibhobho edityanisiweyo ezinemithungo yokuwelda. Umqheba wokwakha uqala ngokufudumeza iibhilithi zentsimbi ezomeleleyo ukuya kumaqondo obushushu angaphezu kwe-1200 ° C, athathwe emva kokubhoboza nge-mandrel ukwenza introduction shape engenanto. Akunjalo konke konke okufana neeChaneli eziWelded, ukwahluka okungaguqukiyo kugcina iipropathi ezithembekileyo ze-metallurgical ngaphandle kokugxila okubuthathaka okunxulumene neendawo ze-weld. Nokuba kuthe kanti, isibambo sokwenza oluntsonkothileyo sifuna izixhobo ezikhethekileyo kunye nokusetyenziswa kwamandla aphezulu, okuza ngeendleko ezandisiweyo zokuvelisa xa kuthelekiswa nokhetho oludityanisiweyo.
