Yazisa:
Umbhobho odibeneyo ojikelezayo uyinxalenye ebalulekileyo kwiiprojekthi ezahlukeneyo zeziseko zophuhliso, kubandakanya imibhobho yeoyile negesi, iinkqubo zokuhambisa amanzi, kunye nokusetyenziswa kwezakhiwo. Njengakweyiphi na imveliso eyenziwe ngobunjineli, iinkcukacha ezithile kufuneka zilandelwe ukuqinisekisa ukusebenza kakuhle nokuthembeka kwezi mibhobho. Kule blog, siza kujonga kwiingxaki zeiinkcukacha zombhobho odibeneyo ojikelezayoukubonelela ngesikhokelo esipheleleyo sokuqonda ngcono le mveliso ibalulekileyo yemizi-mveliso.
1. Inkcazo kunye neenzuzo:
Indlela yokuvelisaumbhobho odibeneyo ojikelezayokukushisela umcu wentsimbi ogoqwe ngobushushu ube yimo yespiral ngokwenza i-spiral eqhubekayo. Imiphetho yestrip idityaniswe kusetyenziswa i-double-side submited arc welding (DSAW) ukwenza umbhobho onamandla aphezulu onokuqina okuphuculweyo kunye nokumelana nokuguquguquka. Iingenelo eziphambili zombhobho we-spiral welded ziquka ukuqina okugqwesileyo kwesakhiwo, amandla afanayo kubude bombhobho, kunye nokukwazi ukumelana noxinzelelo lwangaphakathi oluphezulu.
2. Ububanzi kunye nobukhulu bodonga:
Iinkcukacha zeepayipi ezidityanisiweyo ezijikelezayo ziquka iiparameter ezahlukeneyo, ezona zibalulekileyo kuzo bububanzi kunye nobukhulu bodonga lombhobho. Ezi milinganiselo zixhomekeke kwisicelo esicwangcisiweyo kunye neemeko zokusebenza. Ngokubanzi, umbhobho odityanisiweyo ojikelezayo ufumaneka kuluhlu olukhulu lobubanzi kunepayipi edityanisiweyo edityanisiweyo engumthungo okanye ethe tye, edla ngokuba phakathi kwee-intshi ezi-8 ukuya kwii-intshi ezili-126 (203.2 ukuya kwi-3200 mm) okanye ngaphezulu. Ubukhulu bodonga buqala kwi-6 mm ukuya kwi-25.4 mm nangaphezulu.
3. Udidi lwentsimbi kunye nokwakheka kweekhemikhali:
Ukukhethwa kodidi lwentsimbi kunye nokwakheka kweekhemikhali kudlala indima ebalulekileyo ekumiseleni iimpawu zoomatshini kunye nokumelana nokugqwala kwemibhobho edibeneyo ejikelezayo. Amanqanaba entsimbi asetyenziswa rhoqo kwimibhobho ejikelezayo aquka uthotho lwe-API 5L X, amanqanaba e-ASTM A252 2 kunye ne-3, kunye namanqanaba e-ASTM A139 B kunye ne-C. La manqanaba entsimbi amiselwa ngokusekelwe kumandla okuvelisa kunye ne-carbon equivalent ukuqinisekisa ukusebenza kakuhle kwizicelo ezithile.
4. Uvavanyo kunye nokuhlolwa:
Ukuze kuqinisekiswe umgangatho kunye nokuthembeka kwemibhobho edibeneyo ejikelezayo, abavelisi balandela iinkqubo ezingqongqo zovavanyo kunye nokuhlolwa. Uvavanyo oluphambili olwenziweyo luquka uvavanyo lwe-hydrostatic, uvavanyo olungonakalisiyo (njengokuhlolwa kwe-ultrasonic okanye i-radiographic) kunye novavanyo loomatshini (uvavanyo lokuxinana, ukuvunwa kunye nempembelelo). Olu vavanyo luqinisekisa ukuba imibhobho ihlangabezana namandla afunekayo, ubungakanani kunye nemigangatho yokuvuza.
5. Ukwaleka kunye nokukhuselwa komphezulu:
Ukukhusela iipayipi ezijijekileyo ezijikelezayo ekungcoleni nakwezinye izinto zangaphandle, kukho iindlela ezahlukeneyo zokugquma umphezulu. Ezi ngubo zingabandakanya i-epoxy, i-coal tar enamel okanye i-polyethylene, phakathi kwezinye. Ukongeza, iindlela zokukhusela i-cathodic ezifana ne-sacrificed anodes okanye iinkqubo zangoku ezichukunyisiweyo zingasetyenziselwa ukukhusela iipayipi.
Ukuququmbela:
Ukuqonda iinkcukacha zepayipi edibeneyo ejikelezayo kubalulekile kwiinjineli, abaphathi beeprojekthi kunye nabachaphazelekayo ababandakanyekayo kwiiprojekthi zeziseko zophuhliso. Ngokuqwalasela ububanzi, ubukhulu bodonga, umgangatho wentsimbi, uvavanyo kunye nokukhuselwa komphezulu, unokuqinisekisa ukuba ipayipi iyahlangabezana nemigangatho yokusebenza efunekayo. Ukuthobela ngokufanelekileyo iikhowudi akuqinisekisi nje kuphela ukuba inkqubo yakho yepayipi ihlala ixesha elide kwaye ikhuselekile, kodwa ikwaqinisekisa ukuthuthwa okuthembekileyo kolwelo, iigesi kunye nezinye izinto. Ngokuqwalasela iinkcukacha, iinjineli kunye nabachaphazelekayo banokufikelela kwiziphumo zeprojekthi eziphumelelayo ngelixa behlangabezana nemigangatho nemigaqo efunekayo kushishino.
