Njengoko izicelo zemizi-mveliso ziye zavela kwaye zikhula ngakumbi, iimveliso zokwenza imibhobho neenkqubo ezibakhonzayo kufuneka zigcine isantya.
Nangona iindlela ezininzi zepayipile zikho, eyona ngxoxo ibalaseleyo kushishino lukholo lokuchasana ne-welded (i-Erw) kunye ne-SMLS). Ke yeyiphi engcono?
Umahluko phakathi kwentsimbi engenamthungo yentsimbi kunye nombhobho we-Weldied okwelona gama lithandwayo ngumahluko ngaphandle kwe-WODT, nangona kunjalo, ngokuyinyani umahluko kwinkqubo yemveliso. Ngumahluko kwinkqubo yemveliso ebanika zombini intsebenzo kunye nenjongo.
Ukwenza umbhobho wemveliso engenamthungo
Umbhobho wentsimbi engenamthungo wenziwe ngentsimbi yephepha elinye, umphezulu wombhobho wentsimbi ngaphandle komkhondo wonxibelelwano, obizwa ngokuba ngumbhobho wentsimbi engenamthungo. Ngokwendlela yemveliso, umbhobho oshushu oshushu, umbhobho oshushu ovuthayo, umbhobho obandayo, umbhobho wokutsalwa obandayo, umbhobho wokuphelelwa ngumbhobho wahlulwe ngaphandle.
I-piiling engenamthungo iqala njengendawo eqinileyo ye-cylindrical yentsimbi ebizwa ngokuba yiBillet. Ngelixa ushushu, i-billle isebenzisa i-mandrel ihlatywe kwiziko. Inyathelo elilandelayo kukuqengqeleka kwaye wolula i-billle ye-hillet. Ii-billets ziqengqelwe ngokuchanekileyo kwaye zolule kude kube lixesha, ububanzi kunye nobubanzi bodonga oluchazwe kumyalelo wabathengi.
Ukwenza umbhobho wemveliso we-weldied
Imeko yoqobo yombhobho we-welding lilitye elide elinensimbi. Sika kubude obufunayo kwaye ububanzi ukwenza i-steentar yensimbi yensimbi. Ububanzi bephepha luya kuba luphawu lwangaphandle lombhobho, kwaye eli xabi lingasetyenziselwa ukubala ububanzi bayo bokugqibela. Iphepha elixande ligqitha kwiyunithi eqengqelekayo ukuze amacala amade agobe omnye komnye ukuba enze isilinda. Ngexesha le-Erw, i-Right-Right Rips idluliselwa phakathi kwemiphetho, ebangela ukuba inyibilike kunye ne-fuse kunye.
Umahluko jikelele kukuba:
Umbhobho we-weldid uthathwa njengobuthathaka ngokwendalo kuba kubandakanya enye yed. Iityhubhu ezingenamthungo azinalo esi siphene sesakhiwo esibonakalayo kwaye ke ngoko sithatyathwa sikhuselekile. Nangona umbhobho we-welding ubandakanya ukudityaniswa, le ndlela yemveliso yenza ukunganyamezeli i-welding pipe kungabi ngaphezu kweemfuno zomthengi kunye nobungqingqwa yiyunifomu. Nangona umbhobho ongenamthungo unezibonelelo ezibonakalayo, ukugxekwa kombhobho ongenamthungo kukuba iinkqubo zokuqengqeleka kunye nokuzolula zivelisa ubukhulu obungahambelaniyo.
Kwioyile, igesi, ukuvelisa amandla kunye nemizi-mveliso yamayeza, uxinzelelo oluphezulu kunye nosetyenziso oluphezulu kunye nokusetyenziswa kweqondo lobushushu obufuna ukuqina kwetyhefu. Imibhobho ye-welding ihamba ngexabiso eliphantsi ukuvelisa kwaye isetyenziswe ngokubanzi njengeqondo lobushushu, uxinzelelo kunye nezinye izinto eziguquguqukayo azidluli kwimigangatho efanelekileyo.
Ngokufanayo, akukho mahluko kwintsebenzo phakathi kwe-erw kunye nemibhobho yentsimbi engenamthungo kwizicelo zesakhiwo. Ngelixa ezi zinto zimbini zitshintshiwe, ayinangqondo yokucacisa umbhobho ongenamthungo xa umbhobho we-Weldi otyhafileyo uyasebenza ngokulinganayo.
