Iipayipi zihlala zahlulwa ngokwemilinganiselo emithathu ephambili: izinto, inkqubo yokuvelisa, kunye nokusetyenziswa. Iindidi ezahlukeneyo zeepayipi zesinyithi zinomahluko omkhulu ekusebenzeni kwazo kunye neemeko ezifanelekileyo. Uhlu oluthile lulandelayo:
Ngokwezinto Eziphathekayo
Le yeyona ndlela isisiseko yokwahlulahlula, emisela ukusebenza okuphambili kombhobho wesinyithi.
Iipayipi zesinyithi ezenziwe ngentsimbi
Iipayipi zentsimbi ezingwevu: Zibuthathaka kakhulu kwaye azinabo ukuqina, kodwa azibizi kakhulu. Ngaphambili, zazisetyenziswa kakhulu ekunikezeni amanzi kunye nokuthuthwa kwamanzi, kunye nokunkcenkceshela kwezolimo, kodwa ngoku zithatyathelwa indawo ziipayipi zentsimbi ezithambileyo.
Iipayipi zentsimbi ezixutyiweyo: Ukuqina kwesinyithi esityhidiweyo kuyaphucuka ngonyango lwe-spheroidization. Amandla azo asondele kakhulu kulawo eepayipi zentsimbi, kwaye zinokumelana okunamandla nokugqwala kunye nokumelana nokuhlaliswa kwazo. Zezona zinto ziphambili zepayipi zamanzi emvula kunye neepayipi zamanzi amdaka kunye neepayipi eziphambili zokuhambisa amanzi.
Iipayipi zesinyithi ezithambileyo: Ezibizwa ngokuba “ziipayipi zesinyithi ezithambileyo,” zithambile kwaye kulula ukuzicubungula, zisetyenziselwa ukwenza izixhobo zepayipi (iingqiniba, ii-tee), endaweni yokuhambisa amanzi/igesi kumgama omde.
Iipayipi zentsimbi
Zenziwe ngentsimbi, amandla azo kunye nokuqina kwazo kungaphezulu kakhulu kunemibhobho yentsimbi eyenziwe ngentsimbi, eneentlobo ezininzi ezincinci:
Iipayipi zeNtsimbi yeKhabhoni: Zenziwe ngentsimbi yekhabhoni, zingabizi kakhulu kwaye zisetyenziswa kakhulu ekunikezeni amanzi kunye nokutsalwa kwamanzi, ukuhambisa ubushushu, kunye nokuthuthwa kolwelo oluqhelekileyo kwimizi-mveliso.
Iipayipi zeNsimbi zeAlloy: Eziqulathe izinto zokuxutywa ezifana ne-chromium, i-molybdenum, kunye ne-nickel, ziyamelana namaqondo obushushu aphezulu, uxinzelelo oluphezulu, kunye nokugqwala, kwaye zisetyenziswa kwimizi-mveliso yeekhemikhali, umbane, kunye nepetroleum (ezifana nokuthutha umphunga obushushu obuphezulu kunye nemidiya egqwalisayo).
Iipayipi zeNtsimbi Engagqwaliyo: Ziqulathe i-≥10.5% ye-chromium, zinokumelana nokugqwala okuhle kakhulu kwaye zisetyenziswa ekulungisweni kokutya, kumayeza, nasekususeni ityuwa emanzini olwandle, apho kufuneka khona ucoceko oluphezulu okanye ukumelana nokugqwala.
NgokweNkqubo yoMveliso
Oku kusebenza kakhulu kwimibhobho yentsimbi; iinkqubo ezahlukeneyo zichaphazela ngokuthe ngqo amandla okuthwala uxinzelelo kunye neemeko ezifanelekileyo zemibhobho.
Imibhobho yentsimbi engenamthungo
Ngaphandle kwemithungo yokuwelda, zinamandla aphezulu ngokubanzi kunye nomthamo oqinileyo wokuthwala uxinzelelo, kwaye zahlulwe zaba yimibhobho yentsimbi engenamthungo eqengqelekayo eshushu kunye nemibhobho yentsimbi engenamthungo etsalwa kubanda:
Iipayipi zentsimbi ezingenamthungo eziqengqelekayo ezishushu: Ububanzi obukhulu kunye nobukhulu bodonga obukhulu, ezisetyenziselwa ukuthuthwa kolwelo olunoxinzelelo oluphezulu kunye nezixhobo zesakhiwo soomatshini;
Iipayipi zentsimbi ezingenamthungo ezitsalwa ngokubandayo: Ukuchaneka okuphezulu kunye nomphezulu ogudileyo, osetyenziselwa izixhobo zokuchaneka, iinkqubo ze-hydraulic, njl. Iipayipi zentsimbi ezihlanganisiweyo
Zenziwe ngokuwelda iipleyiti zentsimbi okanye imicu, zibiza kancinci kuneepayipi zentsimbi ezingenamthungo kwaye zahlulwe zibe ziindidi ezimbini:
Iipayipi zentsimbi ezidityaniswe ngomthungo othe tye: Umthungo womthungo uthe tye, kwaye ububanzi bomthungo buncinci. Zisetyenziselwa ukubonelela ngamanzi kunye nokukhupha amanzi ngoxinzelelo oluphantsi, iipayipi zegesi, kunye neepayipi zombhobho;
Iipayipi zentsimbi ezidityaniswe nge-spiral-seam: Umthungo we-weld umile okwe-spiral, unobubanzi obukhulu (ukuya kuthi ga kwiimitha ezi-3), kwaye uqinile kakuhle. Zisetyenziselwa iipayipi eziphambili zegesi zikamasipala kunye neepayipi zamanzi ezinobubanzi obukhulu kwizityalo zonyango lwelindle.
Uhlulo ngokwendlela olusetyenziswa ngayo
Ihlelwe ngokwemeko yesicelo kunye nendlela edluliselweyo, inika ulwazi oluthe kratya:
Imibhobho yentsimbi yokubonelela ngamanzi kunye nokutsalwa kwamanzi: njengemibhobho yamanzi yentsimbi ethambileyo, imibhobho yokukhupha amanzi yentsimbi eyenziwe ngePVC, kunye nemibhobho yamanzi yentsimbi yekhabhoni;
Imibhobho yentsimbi yokuhambisa igesi: efana nemibhobho yentsimbi edityanisiweyo ene-galvanized kunye nemibhobho yentsimbi enomthungo ojikelezayo (efuna unyango lokulwa nokugqwala);
Imibhobho yentsimbi yokufudumeza: efana nemibhobho yentsimbi ye-alloy engatshisiyo kunye nemibhobho yentsimbi egqunyiweyo (enomaleko wokugquma wangaphandle);
Iipayipi zesinyithi zoshishino: ezifana neepayipi ze-alloy ezingamelani nokugqwala ezisetyenziselwa iikhemikhali kunye neepayipi zesinyithi ezingenamthungo ezisetyenziswa kwi-petroleum.
