Yazisa:
Umbhobho odityanisiweyo weSpiral licandelo elibalulekileyo kwiiprojekthi zeziseko ezingundoqo ezahlukeneyo, kubandakanywa imibhobho ye-oyile nerhasi, iinkqubo zokuhanjiswa kwamanzi, kunye nokusetyenziswa kolwakhiwo.Njengayo nayiphi na imveliso yobunjineli, iinkcukacha ezithile kufuneka zithotyelwe ukuqinisekisa ukusebenza kakuhle kunye nokuthembeka kwale mibhobho.Kule bhlog, siza kugocagoca kwizinto ezintsonkothileyospiral welded umbhobho iinkcukachaukubonelela ngesikhokelo esibanzi sokuqonda ngcono le mveliso ibalulekileyo yoshishino.
1. Inkcazo kunye neenzuzo:
Indlela yokuvelisa yeumbhobho odityanisiweyokukuwelda intsimbi eshushu esongwayo ibe yimilo engqukuva ngokuqhubekayo ukujikeleza.Iincam zemicu zidityaniswe kunye kusetyenziswa i-arc ye-arc emacala amabini amacala amabini ukuze yenze umbhobho wokuqina ophezulu kunye nokuqina okwandisiweyo kunye nokuxhathisa ukonakala.Iinzuzo eziphambili zombhobho we-spiral welded zibandakanya ingqibelelo yesakhiwo, amandla afanayo kunye nobude bombhobho, kunye nokukwazi ukumelana noxinzelelo oluphezulu lwangaphakathi.
2. Ububanzi kunye nobukhulu bodonga:
Iimpawu zemibhobho ye-spiral welded ibandakanya iiparitha ezahlukeneyo, ezona zibaluleke kakhulu ubukhulu kunye nobukhulu bodonga lombhobho.Le milinganiselo ixhomekeke kwisicelo esicetywayo kunye neemeko zokusebenza.Ngokubanzi, umbhobho odityanisiweyo ojikelezayo uyafumaneka kuluhlu lwedayamitha enkulu kunombhobho othungelweyo ongenamthungo okanye othe ngqo oqala ukusuka kwi-8 intshi ukuya kwi-126 intshi (203.2 ukuya kuma-3200 mm) okanye ngaphezulu.Ubukhulu bendonga busuka kwi-6 mm ukuya kwi-25.4 mm okanye ngaphezulu.
3. Ibakala lentsimbi kunye nokwakheka kweekhemikhali:
Ukukhethwa kwebakala lentsimbi kunye nokwakheka kweekhemikhali kudlala indima ebalulekileyo ekumiseleni iipropati zomatshini kunye nokumelana nokubola kwemibhobho e-spiral welded.Amanqanaba ensimbi asetyenziswa ngokuqhelekileyo kwimibhobho ejikelezayo abandakanya uchungechunge lwe-API 5L X, i-ASTM A252 ibakala lesi-2 kunye ne-3, kunye ne-ASTM A139 amabakala B kunye no-C. La mabakala ensimbi anqunywe ngokusekelwe kumandla okuvelisa kunye nokulingana kwekhabhoni ukuqinisekisa ukusebenza kakuhle kwizicelo ezithile.
4. Uvavanyo kunye nokuhlolwa:
Ukuze kuqinisekiswe umgangatho kunye nokuthembeka kwemibhobho ye-spiral welded, abavelisi banamathela kuvavanyo olungqongqo kunye neenkqubo zokuhlola.Uvavanyo oluphambili olwenziweyo lubandakanya uvavanyo lwe-hydrostatic, uvavanyo olungonakalisi (olufana nokuhlolwa kwe-ultrasonic okanye i-radiographic) kunye novavanyo lomatshini (i-tensile, isivuno kunye novavanyo lwempembelelo).Ezi mvavanyo ziqinisekisa ukuba imibhobho ihlangabezana namandla afunekayo, ubungakanani kunye nemigangatho yokuvuza.
5. Ukwaleka komphezulu kunye nokhuseleko:
Ukukhusela imibhobho ye-spiral welded kwi-corrosion kunye nezinye izinto zangaphandle, iindlela ezahlukeneyo zokugubungela umphezulu ziyafumaneka.Ezi zambatho zingabandakanya i-epoxy, i-coal tar enamel okanye i-polyethylene, phakathi kwezinye.Ukongezelela, iindlela zokukhusela i-cathodic ezifana ne-anodes yedini okanye iinkqubo zangoku ezichukumisayo zingasetyenziselwa ukukhusela imibhobho.
Ukuququmbela:
Ukuqonda iinkcukacha zemibhobho ye-spiral welded kubalulekile kwiinjineli, abaphathi beeprojekthi kunye nabachaphazelekayo ababandakanyeka kwiiprojekthi zeziseko zophuhliso.Ngokuqwalasela ububanzi, ubukhulu bodonga, ibakala lensimbi, uvavanyo kunye nokukhuselwa kwendawo, unokuqinisekisa ukuba umbhobho udibana nemigangatho yokusebenza efunekayo.Ukuthotyelwa ngokufanelekileyo kunye neekhowudi akuqinisekisi kuphela ixesha elide kunye nokhuseleko lwenkqubo yakho yokubhobhoza, kodwa iqinisekisa ukuthuthwa okuthembekileyo kwamanzi, iigesi kunye nezinye izinto.Ngokuqwalasela iinkcukacha, iinjineli kunye nabachaphazelekayo banokufikelela kwiziphumo zeprojekthi eziyimpumelelo ngelixa behlangabezana nemigangatho kunye nemimiselo yoshishino.
