Umahluko phakathi kweSpiral Steel Pipe kunye neLSAW Steel Pipe

I-Spiral Steel PipekwayeIpayipi yentsimbi ye-LSAWzimbini iindidi eziqhelekileyo zeumbhobho wentsimbi odityanisiweyo, kwaye kukho ukungafani kwindlela yabo yokuvelisa, iimpawu zesakhiwo, ukusebenza kunye nokusetyenziswa.

Inkqubo yokuvelisa
1. umbhobho we-SSAW:
Yenziwa ngokurola intsimbi okanye ipleyiti yentsimbi ibe ngumbhobho ngokweengile ethile ejiyileyo ize idityaniswe.
I-weld seam i-spiral, yahlulwe yaba ziindidi ezimbini zeendlela zokuwelda: i-arc ye-arc enamacala amabini kunye ne-high-frequency welding.
Inkqubo yokuvelisa inokuhlengahlengiswa ububanzi be-strip kunye ne-engile ye-helix, ukuququzelela ukuveliswa kombhobho omkhulu wentsimbi.

 

2. Umbhobho we-LSAW:
Intsimbi yomcu okanye ipleyiti yentsimbi igotywe ngokuthe ngqo kwityhubhu kwaye emva koko idityaniswe ecaleni kwendlela yobude betyhubhu.
I-weld ihanjiswa kumgca othe tye ecaleni kwendlela yobude bomzimba wombhobho, ngokuqhelekileyo usebenzisa i-high-frequency resistance welding okanye i-arc welding ephantsi kwamanzi.

Inkqubo yokuvelisa ilula, kodwa ububanzi bukhawulelwe ngobubanzi bezinto eziluhlaza.
Ngoko ke amandla okuthwala uxinzelelo lombhobho wentsimbi we-LSAW ubuthathaka, ngelixa umbhobho wentsimbi ejikelezayo unomthamo oqinileyo wokuthwala uxinzelelo.
Iinkcukacha
1. Umbhobho weNtsimbi eSpiral:
Ilungele ukuveliswa kombhobho wentsimbi enkulu, enodonga olungqingqwa.
Uluhlu lwe-diameter luhlala luphakathi kwe-219mm-3620mm, kwaye ububanzi bodonga luyi-5mm-26mm.
inokusebenzisa umtya wentsimbi emxinwa ukuvelisa umbhobho obanzi obanzi.

2. Umbhobho wentsimbi we-LSAW:
Ifanele ukuveliswa kwe-diameter encinci, umbhobho wentsimbi ophakathi obhityileyo.
Uluhlu lwe-diameter luhlala luphakathi kwe-15mm-1500mm, kunye noluhlu lwendonga luyi-1mm-30mm.
Ubalulo lwemveliso ye LSAW umbhobho wentsimbi ngokuqhelekileyo ububanzi encinane, lo gama imveliso umbhobho spiral intsimbi ubukhulu becala ubukhulu enkulu. Oku kungenxa yokuba inkqubo yokuvelisa i-LSAW yentsimbi yombhobho imisela uluhlu lwayo oluncinci lwe-caliber, ngelixa umbhobho wensimbi ojikelezayo unokuhlengahlengiswa ngokusebenzisa i-spiral welding parameters ukwenza iinkcukacha ezahlukeneyo zemveliso. Ke ngoko, umbhobho wentsimbi ojikelezayo unenzuzo ngakumbi xa kufuneka umbhobho wentsimbi obubanzi obukhulu, njengakwintsimi yobunjineli bogcino lwamanzi.
Amandla kunye nokuzinza
1. Umbhobho wentsimbi ejikelezayo:
I-welded seams ihanjiswa nge-helically, enokuthi isasaze uxinzelelo kwi-axial direction ye-pipeline, kwaye ngoko ibe nokuchasana okunamandla kuxinzelelo lwangaphandle kunye nokuguqulwa.
Ukusebenza kuzinzile phantsi kweemeko ezahlukeneyo zoxinzelelo, ezifanelekileyo kwiiprojekthi zokuthutha umgama omde. 2.

2. Umbhobho wentsimbi womthungo othe ngqo:
I-Welded seams igxininiswe kumgca othe tye, ukusabalalisa uxinzelelo alufani njengepayipi yensimbi ejikelezayo.
Ukugoba ukuxhathisa kunye namandla onke aphantsi, kodwa ngenxa ye-welding ye-welding efutshane, umgangatho we-welding kulula ukuqinisekisa.
Iindleko
1. Umbhobho wentsimbi ejikelezayo:
Inkqubo enzima, i-welding seam ende, i-welding ephezulu kunye neendleko zokuvavanya.
Ifanele ukuveliswa kwemibhobho emikhulu yobukhulu, ngakumbi kwimeko yobubanzi obunganeleyo be-strip steel ekrwada kuqoqosho ngakumbi. 2.

2. Umbhobho wentsimbi we-LSAW:
Inkqubo elula, ukusebenza kakuhle kwemveliso, umthungo omfutshane we-weld kwaye kulula ukuyibona, ixabiso eliphantsi lokuvelisa.
Ifanelekile kwimveliso yobuninzi bombhobho wentsimbi omncinci ububanzi.

 

Weld imilo yomthungo
I-weld seam ye-LSAW yentsimbi yombhobho ithe tye, ngelixa i-weld seam yombhobho wentsimbi ejikelezayo ijikeleza.
Umthungo we-weld othe ngqo we-LSAW wentsimbi yenza ukuxhathisa kwayo kunciphe, nto leyo ilungele ukuthuthwa kwamanzi, kodwa kwangaxeshanye, inokukhokelela kuxinzelelo loxinzelelo kumthungo we-weld, ochaphazela ukusebenza ngokubanzi. I-spiral weld seam yombhobho wentsimbi ejikelezayo inomsebenzi ongcono wokutywina, onokuthi uthintele ngokufanelekileyo ukuvuza kolwelo, igesi kunye nezinye imidiya.
