Iipayipi zentsimbi ezithambileyo ziye zaba sisiseko seziseko zophuhliso zanamhlanje, ngakumbi kwiinkqubo zokusasazwa kwamanzi kunye nolawulo lwamanzi amdaka. Ezaziwa ngamandla azo nokuqina kwazo, ezi pipes zenziwe ukuze zihlangabezane nemigangatho eyahlukeneyo, kubandakanya ne-ASTM A536 specification, echaza iimfuno zezinto zepayipi zentsimbi ezithambileyo. Phakathi kweendidi ezahlukeneyo ezikhoyo, iipayipi zentsimbi ezithambileyo ze-K9 grade ziphawuleka kakhulu ngeempawu zazo zoomatshini eziphuculweyo, nto leyo ezenza zifaneleke ukusetyenziswa koxinzelelo oluphezulu. Ipayipi yentsimbi ethambileyo ye-DN800, enobubanzi obuqhelekileyo be-800 millimeters, lukhetho oludumileyo kwiiprojekthi ezinkulu, olubonelela ngesisombululo esithembekileyo sokuthutha amanzi kunye nezinye izinto ezimanzi.
Ukusetyenziswa kwemibhobho yesinyithi esithambileyo kukhulu, ukusuka kwiinkqubo zokubonelela ngamanzi zikamasipala ukuya kwizicelo zoshishino. Ukumelana kwayo nokugqwala kunye nokukwazi kwayo ukumelana noxinzelelo oluphezulu kuyenza ifaneleke zombini ukufakwa ngaphezulu komhlaba kunye nangaphantsi komhlaba. Ukongeza, imibhobho yesinyithi esithambileyo idla ngokusetyenziswa kwiinkqubo zokukhusela umlilo, apho ukuthembeka kubaluleke kakhulu. Ukuguquguquka kwezi mibhobho kuvumela ukuba zisetyenziswe kwiindawo ezahlukeneyo, kubandakanya iindawo zasezidolophini, kwiindawo zasemaphandleni, nakwiindawo ezinzima. Njengoko izixeko ziqhubeka nokukhula kwaye iimfuno zeziseko zophuhliso zisanda, imfuneko yezisombululo zemibhobho ezihlala ixesha elide nezisebenzayo njengemibhobho yesinyithi esithambileyo iba yinto ebaluleke ngakumbi.
Xa kuxoxwa ngokuhlelwa kwamanqanaba emibhobho yesinyithi esithambileyo, kubalulekile ukuqonda ukubaluleka kwamanqanaba ahlukeneyo. Umzekelo, inqanaba le-K9 lenzelwe ukujongana namanqanaba aphezulu oxinzelelo xa kuthelekiswa namanqanaba aphantsi, nto leyo eyenza ukuba ifaneleke ukusetyenziswa apho umngcipheko wokunyuka koxinzelelo uxhaphake khona. Iinkcukacha zemibhobho yesinyithi esithambileyo, kubandakanya ubukhulu bodonga kunye nobubanzi, zibalulekile ekumiseleni ukusebenza kwazo phantsi kweemeko ezahlukeneyo. Ubudlelwane phakathi kobubanzi obuqhelekileyo kunye noxinzelelo nalo luyinto ephambili ekufuneka iqwalaselwe; njengoko ububanzi bukhula, umlinganiselo woxinzelelo kufuneka uhlolwe ngononophelo ukuqinisekisa ukuthembeka kwenkqubo. Olu budlelwane lubaluleke ngakumbi kwimibhobho emikhulu, efana nombhobho wesinyithi esithambileyo we-DN800, ekufuneka wenziwe ngendlela yokusingatha imithwalo ebalulekileyo ye-hydraulic.
Njengoko imfuno yehlabathi yemibhobho yesinyithi esithambileyo iqhubeka nokunyuka, iinkampani ezifana neJindalai Steel Company ziphambili ekuveliseni izinto ezintsha kunye nemveliso. Ngokuzibophelela kumgangatho kunye nokuzinza, iJindalai Steel Company izibonakalise njengenkokeli ekuveliseni imibhobho yesinyithi esithambileyo, ithobela imigangatho yamazwe ngamazwe kunye neendlela ezilungileyo. Ukugxila kwenkampani kuphando nophuhliso kuqinisekisa ukuba iimveliso zayo ziyahlangabezana neemfuno eziguqukayo zemarike, ngelixa ikwajongana neengxaki zokusingqongileyo. Njengoko iiprojekthi zeziseko zophuhliso kwihlabathi liphela zibeka phambili ukuqina nokusebenza kakuhle, indima yemibhobho yesinyithi esithambileyo, ngakumbi leyo ihlangabezana nomgangatho we-A536 kunye neenkcukacha zebanga le-K9, ngokuqinisekileyo iya kuhlala ibalulekile ekubumbeni ikamva leenkqubo zolawulo lwamanzi kunye nokusasazwa kwamanzi.
Ukuqukumbela, iipayipi zesinyithi ezithambileyo, ingakumbi ezo zihlelwe phantsi kwe-ASTM A536 kunye ne-K9 grade, zizinto ezibalulekileyo kwiziseko zophuhliso zanamhlanje. Usetyenziso lwazo lugubungela uluhlu olubanzi lwamashishini, kwaye ukuqonda iinkcukacha zazo kunye neempawu zokusebenza kubalulekile kwiinjineli kunye nabaphathi beeprojekthi ngokufanayo. Njengoko iinkampani ezifana neJindalai Steel Company ziqhubeka nokuvelisa izinto ezintsha kunye nokuvelisa iipayipi zesinyithi ezithambileyo ezikumgangatho ophezulu, eli shishini linokulindela ukubona ukuqhubela phambili okuphucula ngakumbi ukuthembeka nokusebenza kakuhle kwezi zinto zibalulekileyo zeziseko zophuhliso.
