Isingeniso se-Shandong Kungang Spiral Pipe
Ipayipi elivunguzayo lenziwa ngokugingqa insimbi yesakhiwo sekhabhoni ephansi noma umucu wensimbi yesakhiwo esinengxubevange ephansi ibe ishubhu elingenalutho ngokwe-engeli ethile ye-helical (ebizwa ngokuthi i-engeli yokuma), bese ishisela imithungo yepayipi. Ingenziwa ngomugqa omncane Insimbi ikhiqiza amapayipi amakhulu ensimbi ububanzi. Ukucaciswa kwayo kuvezwa ububanzi obungaphandle * ukujiya kodonga. Ipayipi elishiselwe kufanele liqinisekise ukuthi ukuhlolwa kwe-hydraulic, amandla aqinile we-weld kanye nokusebenza kokugoba okubandayo kufanele kuhlangabezane nemithethonqubo.
Mayelana nenqubo yokushisela, indlela yokushisela yepayipi elishiselwe okuvunguza kanye nepayipi lensimbi lomthungo iyafana, kodwa ipayipi elithungelwe ngomthungo oqondile lizoba nama-welds amaningi amise okwe-T, ngakho-ke amathuba okuba nokukhubazeka kokushisela nawo anda kakhulu, kanye nezinsalela zokushisela kuma-welds amise okwe-T Ukucindezeleka kukhulu, futhi insimbi ye-weld ivame ukuba nesimo sokucindezeleka se-three-dimensional, okwandisa amathuba okuqhekeka. Ngaphezu kwalokho, ngokwemithetho yezobuchwepheshe ye-arc welding engaphansi kwamanzi, i-weld ngayinye kufanele ibe nendawo yokuqala ye-arc kanye nendawo yokucisha i-arc, kodwa ipayipi ngalinye elihlanganisiwe eliqondile alikwazi ukuhlangabezana nalesi simo lapho kushiselwa umthungo oyindilinga, ngakho-ke kungase kube nezinye izici zokushisela.
sebenzisa
Amapayipi okuvunguza asetshenziswa kakhulu kubunjiniyela bokuhlinzekwa kwamanzi, imboni ye-petrochemical, imboni yamakhemikhali, imboni yamandla kagesi, ukuchelela ngenkasa kwezolimo, kanye nokwakhiwa kwamadolobha. Ungomunye wemikhiqizo engamashumi amabili esemqoka ethuthukiswe izwe lethu. Okokuthutha okuwuketshezi: ukuhlinzekwa kwamanzi, ukuthuthwa kwamanzi, ubunjiniyela bokuhlanza indle, ukuthuthwa kodaka, ukuthuthwa kwamanzi olwandle. Ezokuthutha ngegesi: igesi, umusi, igesi ye-petroleum ewuketshezi. Ngezinhloso zesakhiwo: njengamapayipi okunqwabelanisa namabhuloho; amapayipi ama-wharves, imigwaqo, izakhiwo zokwakha, amapayipi okunqwabelanisa olwandle, njll.
Amazinga Omkhiqizo
Kuvunguza umthungo ongaphansi kwamanzi we-arc oshiselwe ipayipi lensimbi i-SY5036-83 yokuthutha uketshezi olucindezelwe isetshenziselwa ikakhulukazi amapayipi kawoyela negesi yemvelo; spiral seam high frequency ashiselwe ipayipi lensimbi SY5038-83 yokuthutha uketshezi olucindezelwe lushiselwa yi-high frequency lap welding. Amapayipi ensimbi ashiselwe i-Spiral seam high-frequency for transportation fluid transportation. Ipayipi lensimbi linamandla okuthwala ingcindezi, ipulasitiki enhle, futhi ilungele ukushisela nokucubungula; i-spiral seam engaphansi kwe-arc eshiselwe ipayipi lensimbi i-SY5037-83 yokuthutha uketshezi olunengcindezi ephansi yenziwa ngokushisela okuzenzakalelayo kwe-arc okunezinhlangothi ezimbili noma ukushisela ohlangothini olulodwa lwamanzi, igesi, amapayipi ensimbi afakwe i-arc ashiselwe ukudlulisa uketshezi olujwayelekile olunomfutho ophansi. njengomoya nesitimu.
Amazinga asetshenziswa kakhulu amapayipi ensimbi okuvunguza ngokujwayelekile ahlukaniswe abe: SY/T5037-2000 (izinga likangqongqoshe, elaziwa nangokuthi yi-spiral seam submerged arc welded steel pipelines amapayipi ajwayelekile okuthutha uketshezi), GB/T9711.1-1997 (izinga likazwelonke, futhi eyaziwa ngokuthi amapayipi ensimbi ezokuthutha embonini kawoyela negesi) Ingxenye yokuqala yezimo zobuchwepheshe zokulethwa: Ipayipi lensimbi le-A-grade (GB/T9711.2 B-grade ipayipi lensimbi elinezidingo eziqinile), API-5L (American Petroleum Institute, ebizwa nangokuthi ipayipi ipayipi lensimbi; elihlukaniswe ngamaleveli amabili: i-PSL1 ne-PSL2), i-SY/T5040-92 (ipayipi lensimbi elihlanganisiwe le-arc elihlanganisiwe lenqwaba).
