Xa kufikwa kwizicelo zaselwandle, ukuqina nokuthembeka kubaluleke kakhulu. Ukukhetha izinto ezifanelekileyo kwiprojekthi yakho yaselwandle kunokudlala indima ebalulekileyo ekuqinisekiseni ukusebenza okuhlala ixesha elide kunye nokunciphisa iindleko zokugcinwa. Umbhobho wentsimbi engagqwaliyo yaselwandle lukhetho oluhle kakhulu kwiintlobo ngeentlobo zezicelo zaselwandle ngenxa yokumelana kwawo nokugqwala okugqwesileyo kunye namandla. Kweli nqaku, sixoxa ngemigangatho yokukhetha umbhobho wentsimbi engagqwali yaselwandle kwaye sinike ulwazi malunga nendlela yokukhetha eyona ndlela ifanelekileyo kwiimfuno zakho ezithile.
Ngaphambi kokuba ungene kwinkqubo yokukhetha, kubalulekile ukuqaphela ukuba ayizizo zonke iipayipi zentsimbi engagqwaliyo ezifanelekileyo kwiindawo zaselwandle. Indlela amanzi olwandle agqwala ngayo inokubangela umonakalo omkhulu ukuba azisetyenziswanga izixhobo ezifanelekileyo. Yiyo loo nto ukukhetha iityhubhu zentsimbi engagqwaliyo yomgangatho wolwandle kubalulekile ekuqinisekiseni ukuba iiprojekthi zakho zaselwandle zihlala ixesha elide kwaye zihlala ixesha elide.
I-Shandong zhongao steel Co., Ltd. yinkampani eye yaba ngumthengisi ophambili weepayipi zentsimbi engagqwaliyo zaselwandle. Ngamava eminyaka kushishino, banikezela uluhlu olubanzi lweepayipi zentsimbi engagqwali zaselwandle ezikumgangatho ophezulu ezihlangabezana neemfuno ezingqongqo zezicelo zaselwandle.
Xa ukhetha umbhobho wentsimbi engagqwaliyo yolwandle, kukho izinto ezininzi ekufuneka ziqwalaselwe. Okokuqala, kufuneka kumiselwe umgangatho wentsimbi ofanelekileyo kwisicelo sakho solwandle. Iindawo ezahlukeneyo zifuna umgangatho wentsimbi owahlukileyo ukuqinisekisa ukumelana nokugqwala. Amanqanaba entsimbi asetyenziswa rhoqo kwimibhobho yentsimbi engagqwaliyo yolwandle yi-304, 316, 316L, 321, njl.
- 304 Intsimbi Engagqwaliyo: Le yeyona ntsimbi ingenasici ixhaphakileyo kwiindlela zokusetyenziswa elwandle. Inokumelana nokugqwala okuhle kakhulu kwaye kulula ukuyigcina. Nangona kunjalo, isenokungafaneleki kwiindawo ezigqwala kakhulu.
- 316 Intsimbi Engagqwaliyo: 316 Intsimbi Engagqwaliyo yaziwa ngokumelana kwayo nokugqwala kakuhle kwaye isetyenziswa rhoqo kwiindawo zaselwandle apho kukho iikloride kunye nezinye izinto ezigqwaliyo. Ibiza kakhulu kunentsimbi engagqwaliyo ye-304, kodwa ihlala ixesha elide.
-Intsimbi Engagqwaliyo engama-316L: Olu hlobo lwe-316 Stainless Steel olunekhabhoni ephantsi lunokumelana nokugqwala okungcono kwaye luhlala lusetyenziswa kwiindawo ezigqwala kakhulu. Ngenxa yokuba lunekhabhoni ephantsi, lufanelekile kakhulu kwizicelo zokutshintsha ubushushu.
- 321 Intsimbi EngagqwaliyoNgenxa yomxholo we-titanium owongeziweyo, i-321 Stainless Steel inokumelana okuhle kakhulu nokugqwala kwe-intergranular kwaye ifanelekile ukusetyenziswa okubandakanya amaqondo obushushu aphezulu.
Enye into ebalulekileyo ekufuneka iqwalaselwe xa ukhetha umbhobho wentsimbi engagqwaliyo yolwandle bubungakanani kunye nobukhulu bodonga lombhobho. Ubungakanani bombhobho buxhomekeke kwisicelo esithile kunye nokuhamba kwamanzi okufunekayo. Ubukhulu bodonga kufuneka bukhethwe ngononophelo ukuze bumelane noxinzelelo kunye neemeko umbhobho oza kujamelana nazo.
Ukongeza, ukumelana nobushushu kwemibhobho yeyona nto ibalulekileyo ekufuneka iqwalaselwe, ingakumbi kwiindlela zolwandle ezibandakanya izixhobo zokutshintsha ubushushu. Iityhubhu zezixhobo zokutshintsha ubushushu zentsimbi engagqwaliyo kufuneka zenziwe ngezinto ezinokumelana nobushushu obuphezulu ngaphandle kokuphazamisa ulwakhiwo lwazo.
Okokugqibela, kwiindlela zokusebenzisa ulwandle ezibandakanya iimeko ze-cryogenic, kubalulekile ukukhetha iityhubhu zentsimbi engagqwaliyo ezihlala ziqinile kwaye zithambile nokuba zibanda kakhulu. Iityhubhu zentsimbi engagqwaliyo ezigqwaliyo zenzelwe ukugcina amandla azo kumaqondo obushushu angaphantsi kwe-zero, ukuqinisekisa ukusebenza kakuhle kunye nokhuseleko.
Xa kufikwa ekukhetheni imibhobho yentsimbi engagqwaliyo yaselwandle, iShandong zhongao steel Co., Ltd. iyazingca ngokubonelela ngokhetho olupheleleyo oluhlangabezana nemigangatho ephezulu yoshishino. Imibhobho yabo yentsimbi engagqwali yodidi lwaselwandle ikhethwe ngononophelo ukubonelela ngokumelana nokugqwala okuphezulu, ukuqina kunye nokuthembeka kwiintlobo ngeentlobo zezicelo zaselwandle.
