    Ukuqonda ukubaluleka kweenkqubo ze-welding zeplanga ezifanelekileyo zemibhobho yentsimbi esetyenziswa kwimigca yamanzi aphantsi komhlaba

    Ukuqonda ukubaluleka kweenkqubo ezichanekileyo ze-welding ze-spiral pipe ezisetyenziswa kwimigca yamanzi aphantsi komhlaba obhalwe phantsi
    • Ukuqonda ukubaluleka kweenkqubo ze-welding zeplanga ezifanelekileyo zemibhobho yentsimbi esetyenziswa kwimigca yamanzi aphantsi komhlaba

    Inkcazo emfutshane:

    Xa ufaka imigca yamanzi engaphantsi komhlaba, usebenzisa umbhobho osemgangathweni ophezulu kubalulekile ekuqinisekiseni ukuqina kwexesha elide kunye nokuxhathisa kwizinto zokusingqongileyo. Uhlobo olunye lombhobho oqhele ukusetyenziswa kwimigca yamanzi engaphantsi komhlaba yi-spiral pipe yentsimbi. Nangona kunjalo, ukusebenzisa imibhobho esemgangathweni ephezulu akwanelanga ukuqinisekisa ububomi bakho bamanzi. Iinkqubo ezifanelekileyo ze-welding ze-pilding zibalulekile ekuqinisekiseni ukuba imibhobho yentsimbi ye-spiral inokukhulisa phantsi kweemeko eziphantsi komhlaba kwaye inike ukuhanjiswa kwamanzi athembekileyo.


    Iinkcukacha zemveliso

    Iimpawu zeMveliso

     Imibhobho yentsimbi yeSpiralzisetyenziswe ngokubanzi kwimibhobho yamanzi aphantsi komhlaba ngenxa yamandla abo aphezulu kunye nokukwazi ukumelana noxinzelelo lwangaphandle. Imibhobho yenziwa kumzisi oshushu oshushu wensimbi eyenza ubume bemigca. Inkqubo yokuphucula i-welding esetyenziselwa ukwenza le mibhobho inika ingqibelelo efanelekileyo, ibetha izicelo eziphantsi komhlaba.

    I-1.Also iyafumaneka yimibhobho yentsimbi ngohlobo lwangaphandle lwendawo yokuhlala kunye nobubanzi bendawo yokuhlala phakathi kobukhulu obubekiweyo obudweliswe etafileni, kodwa kusayinwe isivumelwano samanani.

    2. Iidayili zangaphandle ezichanekileyo kwizibiyeli etafileni zigciniwe.

    Enye yezona zinto zibalulekileyo zokusebenzisa intsimbi ye-spillyImibhobho yemigca yamanzi engaphantsi komhlabaziinkqubo ezifanelekileyo ze-welding. I-welding yinkqubo yokujoyina iinxalenye ezimbini zentsimbi ngokusebenzisa ubushushu kunye noxinzelelo. Imibhobho yamanzi engaphantsi komhlaba, umgangatho we-welding ichaphazela ngqo ingqibelelo kunye nokuthembeka kombhobho.

    KufanelekileInkqubo ye-welding ye-PelingUmbhobho wentsimbi yeSpils ubandakanya amanyathelo amaninzi. Okokuqala, umphezulu wombhobho oza kwenziwa i-weldid kufuneka acoceke kwaye akhululeke nakuphi na ukungcola okunjengokungcola, ioyile, okanye ipeyinti. Oku kuqinisekisa ukuba i-weld yomelele kwaye ingenazingcolotho ezinokulalanisa amandla.

    I-SSAW PIP

    Emva koko, iiparamitha ze-welding ezifana negalelo lobushushu, isantya se-welding, kwaye ubuchule kufuneka bulawulwe ngononophelo ukuze kufezekiswe i-welds ekumgangatho ophezulu. Ukusebenzisa izixhobo ezifanelekileyo ze-welding kunye neendlela ezifanelekileyo kubalulekile ekuthinteleni iziphene ezinjengentu, okanye ukusilela, okanye ukungathobeki ingqibelelo ye-WED.

    Ukongeza, iinkqubo ezifanelekileyo zokuhamba nge-subred kunye neenkqubo zonyango ezinobushushu zibalulekile kumbhobho wentsimbi yeSpiral esetyenziswa kwimigca yamanzi aphantsi komhlaba. Ukuhamba kuyanceda ukunciphisa umngcipheko wokuqhekeka kwaye kuphuculwe umgangatho we-WED, ngelixa i-Pol-Weld Press inciphisa uxinzelelo lwentsalela kwaye iqinisekisa yonke indawo ye-WOld.

    Ukongeza, ukusetyenziswa kweetekhnoloji ze-welding ze-welding ezinjengeeWelding zeWolding kunye novavanyo olungeyongozi kunokuphucula umgangatho kunye nokuthembeka kwe-welding. Ezi teknoloji zoncedo zinceda ukuba amalungu e-weldid afezekise amandla afanelekileyo kunye nemigangatho esemgangathweni ukubonelela ngoxolo lwengqondo malunga nokusebenza kwexesha elide kwemigca yamanzi aphantsi komhlaba.

    Kwisishwankathelo, iinkqubo ezifanelekileyo ze-welding zibalulekile ekuqinisekiseni ukuthembeka kunye nokuhlala kobomi bombhobho weSpiral esetyenziswa kwimigca yamanzi aphantsi komhlaba. Ngokulandela iiparamitha eziyimfuneko ze-DoDED, ubuchwephesha kunye namanyathelo olawulo lomgangatho, umngcipheko wesiphene selding kunye nokusilela kuncitshiswe kakhulu. Isiphumo sinomgca othembekileyo nonyaka oqinileyo onokwazi ukumelana novavanyo lwexesha kwaye unike iinkonzo zokuhambisa amanzi akhuselekileyo. Kwimigca yamanzi engaphantsi komhlaba, ukutyala imali kwiprogram efanelekileyo ye-welding linyathelo elibalulekileyo ekuqinisekiseni ukuthembeka ngokubanzi kunye nobomi obude bombhobho.
