Okujwayelekile Mayelana Nengxenye Eyodwa Yokuhlanganisa Okuhlanganisayo/Ingxenye Eyodwa Yokuhlanganisa

Amajoyinti ahlanganisiwe we-insulationziwumshini obalulekile wokuxhuma amapayipi oklanyelwe ukuhlinzeka ngokusebenza okuhle kakhulu kokufakwa ukuze kuhlangatshezwane nezidingo ze-conductivity kagesi noma ezishisayo.Lawa majoyinti asetshenziswa kakhulu emikhakheni eyahlukene yezimboni futhi abe negalelo elibalulekile ekuthembekeni nasekuphepheni kwezinhlelo zamapayipi.

Okokuqala, ubukhulu kanye nokucaciswa kwe-inhlanganisela ye-insulation jikelelezihlukahlukene ukuze zifake amapayipi anobubanzi obuhlukene nezinhlobo.Lokhu kuvumelana nezimo kukwenza kube ukukhetha okuhle kwezimo zohlelo lokusebenza ezahlukahlukene.Lawa majoyinti avamise ukuvikeleka futhi azinze ngoxhumo olunentambo, ukuxhumana kwe-flange, nezinye izindlela.

Mayelana nengcindezi, ijoyinti yokufakwa kwe-insulation jikelele yakhelwe ukumelana nohlu oluthile lokucindezela.Lokhu kuyenza ifaneleke ezindaweni ezihlukene zengcindezi, iqinisekise ukuthi uhlelo lwamapayipi lungasebenza ngokuzinza ngaphansi kwezimo zokusebenza ezahlukene.Ikhono layo lokumelana nokucindezela lincike ezintweni ezikhethiwe kanye nezindinganiso zokukhiqiza ezihlangabezana nazo.

Ukusebenza kwe-insulation kulawa majoyinti kungenye yezici zawo ezibaluleke kakhulu.Angakwazi ukuhlukanisa ngokuphumelelayo amandla asakazwayo, avimbele ukuqhutshwa kukagesi, kanjalo anciphise izingozi ezingaba khona zikagesi.Ukwengeza, i-material yejoyinti yokufaka iyonke imvamisa imelana nokugqwala, okwenza isebenze kahle ezindaweni ezinokhahlo, iqinisekise ukusetshenziswa kwesikhathi eside.

Ezindaweni ezinezinga lokushisa eliphezulu, amanye amajoyinti ahlanganisayo abonisa ukusebenza okuhle kakhulu kokumelana nezinga lokushisa eliphezulu.Lokhu kuyenza ikwazi ukusebenza ngokuphepha nangokuthembekile ngaphansi kwezimo zokushisa eziphakeme, ihlinzeka ngesixazululo esifanelekile sezimboni ezidinga izimo zokusebenza ezidlulele.

Kodwa-ke, i-insulation joint isiyonke nayo inezinzuzo zayo kanye nokubi.Enye yezinzuzo ukusebenza kwayo okuthembekile kwe-insulation, okunganikeza ukuxhumana okuzinzile kwamapayipi ezindaweni ezibucayi.Ngaphezu kwalokho, ukumelana kwayo nokugqwala okuphezulu nokumelana nokushisa okuphezulu kuyenza ithandeke kakhulu ezilungiselelweni ezahlukahlukene zezimboni.

Kodwa-ke, uma kuqhathaniswa namanye amalunga angewona ama-insulated, amajoyinti afakwe i-insulated jikelele angase abe nezindleko eziphakeme.Ukuklanywa nokufakwa kwayo kungase kudinge umsebenzi owengeziwe, okungase kwenyuse izindleko eziphelele zamanye amaphrojekthi.Ngakho-ke, lapho ukhetha ukusebenzisa amalunga ahlanganisiwe ahlanganisiwe, kuyadingeka ukuthola ibhalansi phakathi kokucatshangelwa okuphelele kokusebenza nezindleko.

Sekukonke, amajoyinti ahlanganisayo abamba iqhaza elingenakushintshwa emikhakheni yezimboni njengamakhemikhali, i-petroleum, negesi yemvelo.Baqinisekisa ukwethembeka nokuphepha kwezinhlelo zamapayipi, ukuhlinzeka ngesixazululo esisebenzayo nesithembekile sokuxhunywa kwamapayipi ngaphansi kwezimo ezihlukahlukene zokusebenza.

Ukuhlolwa kwamandla

1. Amalunga agqunyiwe nama-flange ahlanganiswe futhi aphumelela ekuhlolweni okungangonakali kufanele ahlolwe amandla ngamunye ngamunye ezingeni lokushisa elingekho ngaphansi kuka-5 ℃.Izidingo zokuhlola kufanele zihambisane nezinhlinzeko ze-GB 150.4.
2. Ingcindezi yokuhlola amandla kufanele ibe izikhathi ezingu-1.5 ingcindezi yokuklama futhi okungenani ibe ngu-0.1MPa omkhulu kunengcindezi yokuklama.Indawo yokuhlola ingamanzi ahlanzekile, futhi ubude bokuhlolwa komfutho wamanzi (ngemuva kokuzinza) akufanele kube ngaphansi kwemizuzu engama-30.Esivivinyweni sokucindezela kwamanzi, uma kungekho ukuvuza ekuxhumekeni kwe-flange, kungekho monakalo ezingxenyeni zokufakwa kwe-insulation, futhi akukho deformation ebonakalayo eyinsalela ye-flange kanye nezingxenye ze-insulation ze-fastener ngayinye, kubhekwa njengokufanelekile.
