Ngenkqubela phambili eqhubekayo yenkqubo yoshishino lwehlabathi, imfuno yeiityhubhu zentsimbi yekhabhoni (ityhubhu ye-cs)luyanda unyaka nonyaka. Njengesixhobo semibhobho esetyenziswa ngokuqhelekileyo, iityhubhu zentsimbi zekhabhoni zisetyenziswa ngokubanzi kwiindawo ezininzi ezifana namandla, ukwakhiwa kunye noshishino lweekhemikhali. Nangona kunjalo, xa kuthengwa i-carbon steel tubes, kufuneka sinikele ingqalelo kwizinto ezithile ezibalulekileyo ukuqinisekisa ukuba umgangatho kunye nokusebenza kweepayipi zetsimbi ezithengiweyo ziya kuhlangabezana nokulindela. Eli nqaku liza kukwazisa ngeminye imiba efuna ingqwalasela xa uthenga iityhubhu zentsimbi yekhabhoni.

Okokuqala, kubaluleke kakhulu ukukhetha izinto ezifanelekileyo. Ukukhethwa kwezinto ze-carbon steel tube kuxhomekeke kwimeko yokusetyenziswa kwayo kunye neemfuno. Ngokubanzi, iityhubhu ze-carbon steel zifanelekile kwiindawo ezininzi eziqhelekileyo zemizi-mveliso, kodwa kwezinye iindawo ezikhethekileyo, ezifana neendawo ezihlala elwandle okanye iindawo zokubola kweekhemikhali, kuyimfuneko ukusebenzisa izinto ezinokumelana nokugqwala okungcono, njengeiityhubhu zensimbi ezingenasici. Ngoko ke, kuyimfuneko ukucacisa iimfuno zezinto eziphathekayo ngaphambi kokuthenga kwaye ukhethe ityhubhu ye-carbon steel efanelekileyo.

Okwesibini, ukukhetha ngononophelo ababoneleli nako kubalulekile. Ukukhetha umthengisi ohloniphekileyo kunye namava kunokuqinisekisa ukuthengwa kweetyhubhu ze-carbon steel ezithembekileyo. Xa ukhetha umthengisi, ungabhekisa kwiziqinisekiso zakhe, izixhobo zokuvelisa, amandla obuchule kunye nenkonzo emva kokuthengisa. Kwangaxeshanye, unokufunda malunga nomgangatho wemveliso yomthengisi kunye nesimo sengqondo senkonzo ngokudibana neerekhodi zentengiselwano zembali yomthengisi kunye novavanyo lwabathengi. Kuphela kungokusebenzisana nabanikezeli abathembekileyo onokukuphepha ukuthenga iimveliso ezikumgangatho ophantsi okanye ukudibana nenkonzo embi emva kokuthengisa.

Ngaphezu koko, ixabiso ayisiyiyo kuphela into eqwalaselwayo. Nangona ixabiso liyinkxalabo enkulu kubathengi, xa kuthengwa i-carbon steel tubes, umntu akufanele agxininise kuphela kwixabiso kwaye angawunaki umgangatho kunye nokusebenza kwemveliso. Amaxabiso aphantsi adla ngokuthetha umgangatho wemveliso ongathembekanga. Ngoko ke, xa kuthengwa iibhobho zetsimbi, ukulingana phakathi kwexabiso kunye nomgangatho kufuneka kuthathelwe ingqalelo ngokubanzi. Kuphela ngokukhetha iimveliso ezingabizi kakhulu, oko kukuthi, imibhobho ye-carbon steel ephezulu kunye namaxabiso afanelekileyo, sinokuhlangabezana ngcono neemfuno zeprojekthi.

Ukongeza, kukwabalulekile ukuba ube nolawulo olungqongqo kwinkqubo yokuthenga. Ngaphambi kokuqala ukuthengwa, kuyimfuneko ukucacisa iimfuno, ukwenza isicwangciso sokuthenga, kunye nokunxibelelana ngokupheleleyo nomthengisi. Qinisekisa ukuba ikhontrakthi yokuthenga iqulethe iinkcukacha ezicacileyo, ubuninzi, ixesha lokuhambisa kunye neminye imixholo ebalulekileyo ukuphepha iingxabano ezilandelayo. Emva kokufumana iimpahla, ukuhlolwa kufuneka kuqhutywe ngokungqongqo ngokuhambelana neemfuno zekhontrakthi ukuqinisekisa ukuba iipayipi zetsimbi ezithengiweyo zihlangabezana neemfuno. Ukongeza, kukwayimfuneko ukwenza uvandlakanyo lwentsebenzo yababoneleli ngamaxesha ngamaxesha ukuqinisekisa umgangatho wenkonzo kunye nomgangatho wemveliso yababoneleli ngeenkonzo kwinkqubo yonikezelo.

Ekugqibeleni, inkonzo yexesha elifanelekileyo emva kokuthengisa yinxalenye ebalulekileyo yenkqubo yokuthengwa kombhobho we-carbon steel. Kwinkqubo yokusebenzisa i-carbon steel tubes, akunakuphepheka ukuba ezinye iingxaki ziya kudibana nazo, ezifana nokuguga kombhobho kunye nokuvuza. Umniki-nkonzo onoxanduva kufuneka abonelele ngenkonzo yangexesha emva kokuthengisa ukusombulula iingxaki abadibana nazo ngabasebenzisi ngexesha lokusetyenziswa. Ungabhekisa kuvavanyo lwabasebenzisi bangaphambili kunye nokuzibophelela kwenkonzo yomthengisi ukukhetha umboneleli onokubonelela ngenkonzo ebanzi kunye nangexesha emva kokuthengisa.

Ngamafutshane, kukho imiba emininzi ekufuneka iqwalaselwe xa kuthengwa iityhubhu ze-carbon steel. Ukukhethwa ngokufanelekileyo kwezinto eziphathekayo, ukukhethwa kwababoneleli abathembekileyo, ibhalansi phakathi kwexabiso kunye nomgangatho, ulawulo olungqongqo lwenkqubo yokuthengwa kwempahla, kunye nokugxininiswa kwenkonzo emva kokuthengisa izitshixo zokuqinisekisa ukuba iityhubhu ze-carbon steel ezithengiweyo zinokuhlangabezana neemfuno zomgangatho. Ndiyathemba ukuba ukuqaliswa kweli nqaku kunokukunceda wenze izigqibo ezingcono zokuthenga iityhubhu zensimbi zekhabhoni.
