Intshayelelo ye-Shandong Kungang Spiral Pipe
Umbhobho ojikelezayo wenziwa ngokuqengqeleka kwentsimbi enekhabhoni ephantsi yekhabhoni yolwakhiwo okanye icwecwe lentsimbi yolwakhiwo olusezantsi kwityhubhu engenanto ngokweengile yehelical (ebizwa ngokuba yi-engile yokubumba), kwaye emva koko ukuwelda imithungo yombhobho.Inokwenziwa ngomcu ocutheneyo Intsimbi ivelisa imibhobho yentsimbi enobukhulu obukhulu.Iimpawu zayo zibonakaliswa ngedayamitha yangaphandle * ubukhulu bodonga.Umbhobho odibeneyo kufuneka uqinisekise ukuba uvavanyo lwe-hydraulic, ukuqina kokuqina kwe-weld kunye nokusebenza kokugoba okubandayo kufuneka kuhlangabezane nemimiselo.
Ngokumalunga nenkqubo yokuwelda, indlela yokuwelda i-spiral welded welding kunye ne-straight seam welding pipe iyafana, kodwa umbhobho odityanisiweyo othe tye uya kuba ne-welds eninzi ene-T-shaped welds, ngoko ke amathuba okuba neziphene zokuwelda zikwande kakhulu. kunye ne-welding residue kwii-welds ezinokwakheka kwe-T Uxinzelelo lukhulu, kwaye isinyithi se-weld sihlala sikwimeko yoxinzelelo lwesithathu-dimensional, okwandisa amathuba okuqhekeka.Ngaphezu koko, ngokwemigaqo yobugcisa be-arc welding ephantsi kwamanzi, i-weld nganye kufuneka ibe nendawo yokuqala ye-arc kunye nendawo yokucima i-arc, kodwa umbhobho ngamnye odibeneyo odibeneyo awukwazi ukuhlangabezana nale meko xa udibanisa umthungo ojikelezayo, ngoko ke kunokubakho iziphene ze-Welding.
sebenzisa
Imibhobho eSpiral isetyenziswa ikakhulu kubunjineli bonikezelo lwamanzi, ishishini lepetrochemical, ishishini lemichiza, ishishini lamandla ombane, ukunkcenkceshela kwezolimo, kunye nokwakhiwa kwedolophu.Yenye yeemveliso ezingamashumi amabini eziphambili eziveliswe lilizwe lethu.Ukuthutha ulwelo: unikezelo lwamanzi, ukuhanjiswa kwamanzi, ubunjineli bokucoca ugutyulo, ukuthuthwa ngodaka, ukuthuthwa kwamanzi olwandle.Ukuthutha igesi: igesi, umphunga, igesi yepetroleum engamanzi.Ngeenjongo zesakhiwo: njengemibhobho yokufumba kunye neebhulorho;imibhobho yeendawo zokuloba, iindlela, izakhiwo zezakhiwo, imibhobho yokufunxa yaselwandle, njl.
Imigangatho yeMveliso
Spiral umthungo entywiliselwe arc welded umbhobho wentsimbi SY5036-83 kuthutho ulwelo olucinezelekileyo isetyenziswa ikakhulu kwimibhobho yeoli kunye nerhasi yendalo;spiral umthungo high frequency welded umbhobho wentsimbi SY5038-83 kuthutho ulwelo olucinezelekileyo ludityaniswe yi welding high frequency lap.Imibhobho yentsimbi edityanisiweyo ye-Spiral ye-frequency ephezulu yokuhambisa ulwelo olucinezelekileyo.Umbhobho wentsimbi unamandla okuthwala uxinzelelo, iplastiki elungileyo, kwaye ilungele ukuwelda kunye nokucubungula;Umthungo ojikelezayo ontywilisiweyo we-arc odityanisiweyo wentsimbi umbhobho SY5037-83 kuthutho oluphantsi loxinzelelo oluphantsi jikelele lwenziwa ngokudibanisa kwe-arc kumacala amabini oluzenzekelayo okanye ukuwelda kwicala elinye emanzini, igesi, imibhobho yentsimbi edityanisiweyo ye-arc yokuhambisa ulwelo oluphantsi koxinzelelo jikelele. ezifana nomoya kunye nomphunga.
Imigangatho eqhelekileyo esetyenziswayo kwimibhobho yentsimbi ejikelezayo yahlulwe ngokubanzi ibe: SY/T5037-2000 (umgangatho wolungiselelo, okwaziwa ngokuba yi-spiral seam entywiliselweyo i-arc welding yentsimbi yemibhobho yokuhambisa ulwelo oluqhelekileyo), GB/T9711.1-1997 (umgangatho wesizwe, nayo eyaziwa ngokuba yimibhobho yentsimbi yothutho lweoyile negesi) Inxalenye yokuqala yokuhanjiswa kweemeko zobugcisa: umbhobho wentsimbi we-A-grade (GB/T9711.2 Umbhobho wentsimbi we-B-grade oneemfuno ezingqongqo), i-API-5L (i-American Petroleum Institute, ekwabizwa ngokuba ngumbhobho. umbhobho wentsimbi, owahlulwe ngokwamanqanaba amabini: PSL1 kunye ne-PSL2), SY/T5040-92 (umbhobho wentsimbi odityanisiweyo we-arc odityanisiweyo weemfumba).
