Iinkcukacha zemveliso

Iimpawu zeMveliso

Iumbhobho wamanzi phantsi komhlabangumbhobho wentsimbi ye-spiral esenziwe yinkqubo ehamba-mbini ye-arc ye-arc ye-arc. Umbhobho wenziwe kwikhoboka lentsimbi kwaye ukhutshiwe kwiqondo lokushisa elingapheliyo lokuqinisekisa ukuqina kunye nobomi obude.

Iipropathi eziphambili zomzimba kunye neekhemikhali zemibhobho yentsimbi (GB / T30991-2008, GB / T9711-2011 kunye ne-API ye-5L)

Ulwakhiwo lwe-Pipe's Spiral-ehanjisiweyo luqinisekisa ukuba lomelele kakhulu kwaye ungamelana noxinzelelo-ukuyenza ukhetho olugqibeleleyo lweenkqubo zamanzi ezingaphantsi komhlaba.

Ukongeza kumandla kunye nokuqina, imibhobho yamanzi engaphantsi komhlaba yenzelwe ukwenziwa kokufakwa. Ulwakhiwo lwe-Spiral Seam lube bhetyebhetye kwaye lube nokuziqhelanisa, ukuvumela ukuba kube lula ukuthoba kunye nokuma kweyona ndawo inzima. Oku kuthetha ukuba ungabeka imibhobho ngokukhawuleza kwaye ngokufanelekileyo, ukugcina ixesha kunye neendleko zabasebenzi.

Ukongeza, ukusetyenziswa kwezixhobo ezisemgangathweni eziphezulu kunye netekhnoloji ye-weldy eqinisekisa ukuba imibhobho yamanzi engaphantsi komhlaba ixhaphake kakhulu kukungabinamthi kunye nokugqobhoza. Oku kuthetha ukuba kuya kugcina ukuthembeka kunye nokusebenza kwayo iminyaka, nakwiimeko eziphantsi komhlaba.

Imibhobho yethu yamanzi engaphantsi komhlaba iyafumaneka kwiisayizi ezahlukeneyo zokuhlangabezana neemfuno ezithile zeprojekthi yakho. Nokuba ubeka ubonelelo lwamanzi amancinci asekhaya okanye inkqubo enkulu yemizi-mveliso, sinombhobho ogqibeleleyo wenu. Iqela lethu leengcali linakho ukubonelela ngeengcebiso ezilungiselelwe kunye nenkxaso ekukuncede ukhetha imibhobho ehambelana neemfuno zakho.

Xa kufikwa kwiinkqubo zamanzi aphantsi komhlaba, ufuna umbhobho onokumthemba. Ngomgangatho odibeneyo wokwakha, izinto ezisemgangathweni kunye neengcali ze-welding, imibhobho yethu yamanzi ilungele nayiphi na inethiwekhi yokubonelela ngamanzi. Ihlala ihleli, inokuthenjwa kwaye kulula ukuyifaka, lo mbhobho uza kuvavanywa ixesha lokuvavanywa kwexesha, ukunika uxolo lwengqondo kunye nokusebenza okuphezulu.

Konke, imibhobho ye-Spiral Seam yeyona nto ikhethiweyo kuye nabani na ofuna isisombululo esiphezulu esiphezulu, esinokuthenjwa, nesiqinileyo. Ngomqolo wayo ophumileyo weSpelly kunye nengcaliI-pie yentsimbi yentsimbi, umbhobho unika amandla angafakwanga cala, ukutshintsha kunye nokunganyangeki. Sukulalanisa kumgangatho wenkqubo yakho yamanzi aphantsi komhlaba - khetha imibhobho yamanzi engaphantsi komhlaba njengesisombululo onokumthemba.

Ngaphambili: Iipayipi ezinkulu ze-SSAOMS SMSAIL ze-Pielines zegesi

Okulandelayo: Imibhobho ye-Willral Welding kumgca wegesi engaphantsi komhlaba
