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. Iinkcukacha 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. Kuthutho lwamanzi: 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 yentsimbi SY5036-83 kuthutho ulwelo olucinezelekileyo isetyenziswa ikakhulu kwimibhobho yeoli kunye negesi yendalo; spiral umthungo high frequency welding welding yentsimbi umbhobho SY5038-83 kuthutho olucinezelekileyo ulwelo ludityaniswe nge welding i-high frequency lap welding. 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 ngokubanzi lwenziwa ngokuwelda okuzenzekelayo okuntywiliselwayo kwe-arc okanye icala elinye lamanzi, igesi, i-arc edityanisiweyo yemibhobho yentsimbi yokuhambisa ulwelo oluphantsi loxinzelelo ngokubanzi. ezifana nomoya kunye nomphunga.
Imigangatho eqhelekileyo esetyenziswayo kwimibhobho yentsimbi ejikelezayo yahlulahlulwe ngokubanzi ibe: SY/T5037-2000 (umgangatho wolungiselelo, okwaziwa ngokuba yi-spiral seam submerged arc welded steel pipelines for the common fluid transportation pipelines), 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 B-grade umbhobho wentsimbi kunye neemfuno ezingqongqo), i-API-5L (i-American Petroleum Institute, ekwabizwa ngokuba ngumbhobho. umbhobho wentsimbi;
