Xa kufunwa iimveliso zentsimbi engagqwaliyo kwiprojekthi entsha, amagama athi “ipayipi” kunye “netyhubhu” adla ngokusetyenziswa ngokutshintshana. Nangona kunjalo, ipayipi kunye netyhubhu yentsimbi engagqwaliyo zichazwa, zenziwe, kwaye zivavanywa ngokwahlukileyo, kwaye ukukhetha engalunganga kunokukhokelela ekungahambelani kobukhulu, iindleko ezingeyomfuneko, okanye imiba yokusebenza.
Isitshixo sokuqonda umbhobho wentsimbi engagqwaliyo xa kuthelekiswa nombhobho asikokubonakala kwawo nje kuphela. Kuya kufuneka uqwalasele indlela imveliso elinganiswa ngayo, ukuba ilandela wuphi umgangatho, ukunyamezela kwayo ubukhulu, iimfuno zezinto eziphathekayo, kunye neemeko eza kusebenza kuzo.
Esi sikhokelo sichaza umahluko phakathi kombhobho nombhobho, sithelekisa iimpawu zazo eziphambili, kwaye sinike iingcebiso ezisebenzayo zokukhetha ukusetyenziswa kwemizi-mveliso.
1. Yintoni iPipe yeNtsimbi Engagqwaliyo?
Umbhobho wentsimbi engatyiwayo yimveliso engenanto, ngokubanzi engqukuva eyenzelwe ngokukodwa ukuthutha ulwelo, iigesi, umphunga, okanye ezinye izinto ezisetyenziswayo. Ubukhulu bepayipi buhlala buchazwa ngobukhulu bepayipi eqhelekileyo (i-NPS) kunye neshedyuli, kunye nobubanzi bangaphandle kunye nobukhulu bodonga obumiselwe ngumgangatho ofanelekileyo.
Umzekelo, i-ASTM A312 igubungela umbhobho wentsimbi engenamthungo, ethe tye, kunye nombhobho wentsimbi engenasici e-austenitic esetyenziswa kakhulu ebanda eyenzelwe inkonzo yobushushu obuphezulu kunye neyokubola ngokubanzi.
Iipayipi zentsimbi engagqwaliyo zikhethwa kakhulu xa ukuphathwa koxinzelelo, umthamo wokuhamba kwamanzi, ukumelana nokugqwala, kunye nokuhambelana nezixhobo zepayipi kubalulekile.
Iinketho eziqhelekileyo ziquka umbhobho wentsimbi engagqwali engenamthungo kunye ne-welded, kunye neeklasi ezifana ne-304, 304L, 316, 316L, 321, 347H, kunye nezinye iiklasi ezikhethekileyo ezifumanekayo kwiimeko ezahlukeneyo zenkonzo.
2. Yintoni ityhubhu yentsimbi engagqwaliyo?
Ityhubhu yentsimbi engagqwaliyo yimveliso engenanto eyenziwe ngokugxininisa ngakumbi kubukhulu obuchanekileyo, iimpawu zoomatshini, ukugqitywa komphezulu, okanye iimfuno ezithile zesicelo. Iityhubhu ezingqukuva ziqhelekile, ngelixa iiprofayili zesikwere, ezizinxantathu, kunye nezinye ziyafumaneka ngokuxhomekeke kwinkcazo yokwenziwa.
Ngokungafaniyo nobukhulu obuqhelekileyo beepayipi, iityhubhu zihlala zicwangciswa ngobubanzi bangaphandle kunye nobukhulu bodonga. Oku kuzenza zilungele ukusetyenziswa apho ukuchaneka kobukhulu kunye nejometri elawulwayo kubalulekile.
Umzekelo, ityhubhu yentsimbi engagqwaliyo ye-ASTM A213 yenzelwe ngokukodwa inkonzo yebhoyila engenamthungo, i-superheater, kunye nenkonzo yokutshintsha ubushushu. Ingcaciso ibandakanya iimfuno zonyango lobushushu, uvavanyo loomatshini, kunye novavanyo olungenakonakala okanye olungenamanzi.
Ngoko ke, ityhubhu akufuneki ithathwe ngokuzenzekelayo njengohlobo oluncinci okanye oluncinci lombhobho. Iinkcukacha ezifanelekileyo kunye nenkonzo ecetywayo zichonga ukuba imveliso iyintoni kanye kanye.
3. Umahluko o-6 phakathi kwePipe yeNtsimbi engaGciniyo kunye neThubhu
Nangona iipayipi zentsimbi engagqwaliyo kunye neetyhubhu zinokubonakala zifana, ziyilwe ngokwemigangatho eyahlukeneyo kunye neemfuno zokusebenza. Ukuqonda la mahluko kunceda abathengi ukuba bakhethe imveliso echanekileyo, baphephe iimpazamo zeenkcukacha, kwaye baphucule iindleko zeprojekthi.

Ubungakanani kunye nomlinganiselo
Umahluko obalulekileyo phakathi kombhobho kunye netyhubhu yindlela ezilinganiswa kwaye zichazwe ngayo.
Iipayipi zentsimbi engagqwaliyo zihlala zichongwa yiNominal Pipe Size (NPS) kunye neSchedule (SCH). Ubungakanani obuqhelekileyo busebenza njengesalathiso kushishino endaweni yokumela ububanzi bangaphakathi okanye bangaphandle ngqo. Umzekelo, ipayipi ye-2-intshi ayinyanzelekanga ukuba ibe nobubanzi bangaphandle be-2-intshi.
Iityhubhu zentsimbi engenasici, Kwelinye icala, zichazwe kusetyenziswa ububanzi bazo bangaphandle, ubukhulu bodonga, kwaye ngamanye amaxesha ububanzi bangaphakathi. Le ndlela inika ulawulo oluchanekileyo ngakumbi kwaye ivumela iinjineli ukuba zikhethe iityhubhu ngokusekelwe kwiimfuno zoyilo oluchanekileyo.
Kumaqela okuthenga, olu mahluko lubalulekile kuba uku-odola ityhubhu kusetyenziswa ubukhulu bepayipi—okanye ngokuchaseneyo—kunokubangela iimpazamo zokuthenga ezibizayo.
Inkqubo yoMveliso
Zombini iipayipi zentsimbi engagqwaliyo kunye neetyhubhu zinokwenziwa ngeendlela zokwenza ezingenamthungo okanye ezidityanisiweyo, kodwa ingqwalasela yemveliso yahlukile.
Ukuveliswa kwemibhobho yentsimbi engagqwaliyo yemizi-mveliso kubeka phambili ukuthotyelwa koxinzelelo, ukusebenza kakuhle kokuhamba kwamanzi, kunye nokuthobela imigangatho yemibhobho. Imibhobho engenamthungo idla ngokukhethwa kwiinkqubo zoxinzelelo oluphezulu, ngelixa imibhobho edibeneyo isetyenziswa kakhulu kwiinkqubo zenkqubo ngokubanzi.
Iityhubhu zentsimbi engagqwaliyo zihlala zilungiswa ngakumbi njengokutsalwa okubandayo, ukutsalwa, ukupolisha, okanye ubungakanani obuchanekileyo. La manyathelo ongezelelweyo okuvelisa aphucula ukufana kobukhulu, ukugqitywa komphezulu, kunye neempawu zoomatshini.
Ngenxa yoko, ukuveliswa kweetyhubhu ngokubanzi kubandakanya iimfuno zolawulo lomgangatho oluqinileyo kunokwenziwa kweepayipi eziqhelekileyo.
Imigangatho yoMveliso
Omnye umahluko omkhulu phakathi kombhobho kunye netyhubhu yinkcazo elawulayo.
Iipayipi zihlala zenziwe ngokwemigangatho efana nale:
