Izisombululo zeMigca yeGesi yendalo engaphantsi komhlaba – Umqokeleli weMibhobho ye-SSAW

Kwicandelo lokwakha neleziseko ezingundoqo elihlala litshintsha, imfuneko yezisombululo zemibhobho ezinokuthenjwa nezihlala ixesha elide ibaluleke kakhulu. I-Cangzhou Spiral Steel Pipes Group Co., Ltd. ime phambili kweli shishini, inikezela uluhlu olubanzi lwemibhobho edibeneyo eyenzelwe ngokukodwa ukusetyenziswa kwemigodi. Ngobubanzi obuqala kwi-219 mm ukuya kwi-3500 mm emangalisayo kunye nobude obunye ukuya kuthi ga kwi-35 yeemitha, iimveliso zethu zenzelwe ukuhlangabezana neemfuno ezingqongqo zeeprojekthi ezahlukeneyo, kubandakanya imibhobho yegesi engaphantsi komhlaba.

Umgangatho Ongenakuthelekiswa Nanto Nokuguquguquka Kwezinto

KwiCangzhou Spiral Steel Pipe, siyazingca ngokuzinikela kwethu kumgangatho ophezulu kunye nokuguquguquka. Iipayipi zethu ezidityanisiweyo zenziwe kusetyenziswa ubuchwepheshe obuphambili kunye nezixhobo ezikumgangatho ophezulu, ukuqinisekisa ukuba ziyakwazi ukumelana noxinzelelo kunye nemingeni yokufakelwa komhlaba. Nokuba usebenza kwiprojekthi enkulu yeziseko zophuhliso okanye usetyenziso olukhethekileyo, iipayipi zethu zibonelela ngokusebenza okuphezulu kunye nobomi benkonzo.

Funda ngeepayipi ezidityanisiweyo ezijikelezayo:

Umbhobho odibeneyo ojikelezayosisisombululo esitsha kwiinkqubo zemibhobho yamanzi engaphantsi komhlaba. Yenziwa ngokuwelda imicu yentsimbi okanye iipleyiti/ikhoyili ibe yi-spiral ejikeleze i-mandrel ephakathi. Le nkqubo iqinisekisa umbhobho owelding onamandla aphezulu, ukuguquguquka kunye nokumelana nokugqwala. Umbhobho ophumayo unezibonelelo ezininzi ezenza ukuba ulungele ukufakwa kwemibhobho yamanzi engaphantsi komhlaba.

1. Amandla nokuqina:

Inkqubo yokudibanisa i-spiral welding yonyusa amandla kunye nokuthembeka kombhobho. Ii-spiral welds eziqhubekayo zisasaza uxinzelelo ngokulinganayo kubude, zinciphisa amathuba okusilela kombhobho. Nokuba ujongene nokuhamba komhlaba okanye uxinzelelo lwangaphandle, umbhobho odibanisa i-spiral welded unokumelana nemingeni enxulumene nokufakelwa komhlaba ixesha elide.

2. Ukumelana nokugqwala:

Imigca yamanzi angaphantsi komhlaba isengozini yokugqwala ngenxa yokufuma, i-asidi yomhlaba, kunye nezinye izinto ezingqongileyo. Nangona kunjalo, iipayipi ezifakwe kwi-spiral welded zihlala zigqunywe ngeengqimba ezahlukeneyo zokukhusela, ezifana ne-polyethylene okanye i-epoxy, ukuze zisebenze njengomqobo wokulwa nokugqwala. Olu gqubuthelo lunceda ukwandisa ubomi beepayipi kwaye lunciphise iindleko zokugcina.

3. Ufakelo oluguquguqukayo nolulula:

Ngenxa yesakhiwo sayo esijikelezayo, umbhobho odibeneyo ojikelezayo ubonakalisa ukuguquguquka okugqwesileyo, okwenza kube lula ukuwuphatha ngexesha lokufakwa. Ukulungelelaniswa kwezi mbhobho kuvumela ukulungelelaniswa okusebenzayo nokungabizi kakhulu nokuba kukwindawo enzima okanye xa ujikeleza iziseko zophuhliso ezikhoyo. Oku kuguquguquka kunceda ukukhawulezisa ukwakhiwa nokunciphisa ukuphazamiseka kuluntu ngexesha lokufakelwa.

4. Uthutho lwamanzi olufanelekileyo:

Umphezulu ongaphakathi wombhobho odibeneyo ojikelezayo uthambile, nto leyo enokunciphisa ukungqubana kunye nokulahleka koxinzelelo xa amanzi ehamba ngombhobho. Ukusebenza kakuhle kokuhamba kwamanzi kwenza ukuba amanzi amaninzi athuthwe kumgama omde, nto leyo ephucula ukusasazwa kwamanzi kuthungelwano lonke.

Izisombululo zobungcali zemibhobho yegesi yendalo engaphantsi komhlaba

Enye yezona zinto ziphambili ezisetyenziswayo kwiipayipi zethu ezidityanisiweyo kukwakha iipayipi zegesi ezingaphantsi komhlaba. Ezi payipi zifuna izinto ezinokumelana neemeko ezinzima zokusingqongileyo kwaye zigcine ulungelelwaniso lwesakhiwo. Iipayipi zethu ze-SSAW (Spiral Submerged Arc Welded) zilungele kakhulu le njongo, zibonelela ngesisombululo esomeleleyo esihlangabezana nemigangatho yoshishino yokhuseleko nokuthembeka.
