Eli nqaku lichaza ngakumbi ngenkqubo yemveliso, iimpawu zobugcisa eziphambili, amasimi aphambili okusetyenziswa, kunye neenzuzo ezibalulekileyo zeA106GRBumbhobho owandiswe ngobushushu xa uthelekiswa neendlela zemveli zokuvelisa, nto leyo enika isalathiso sokukhethwa kunye noyilo lobunjineli oluhambelanayo.

1. Itekhnoloji ePhambili: Isishwankathelo seNkqubo yoKwandisa okuShushu

Inkqubo yokwandisa okushushu yiteknoloji yokucubungula eyandisiweyo esekelwe kwimveliso yepayipi yentsimbi engenamthungo. Umbindi wayo ubandakanya ukuthatha ipayipi yentsimbi engenamthungo enobubanzi obuncinci (ipayipi kamama) eyenziwe ngokuqengqeleka okushushu okanye ukutsalwa okubandayo, uyifudumeze ngokulinganayo ukuya kuluhlu lobushushu obuqinisiweyo phantsi kweemeko zobushushu obuphezulu ezilawulwa ngokuchanekileyo kusetyenziswa ukufudumeza okuqhelekileyo okuphakathi okanye isithando somlilo sokuhamba. Emva koko, ukwandiswa kwe-radial kwenziwa nge-mandrel eyandayo yangaphakathi (njengeplagi ekhonkrithi) ukuze ekugqibeleni ufumane ipayipi yentsimbi enobubanzi obukhulu oyifunayo.

Isitshixo sale nkqubo sisekulawuleni ubushushu ngokuchanekileyo kunye nolawulo lokuguqulwa, ukuqinisekisa ukuhamba kwesinyithi okufanayo kunye nesakhiwo se-metallographic esizinzileyo okanye esilungisiweyo (ngesiqhelo i-ferrite + i-pearlite yentsimbi yeBanga B) ngexesha lokwandiswa, ngaloo ndlela kuqinisekiswa ukuba iipropati zoomatshini zemveliso yokugqibela ziyahlangabezana okanye zidlula iimfuno ezisemgangathweni.

2. Iimpawu eziphambili ze-A106GRB Hot-Expanded Pipe

Umbhobho we-A106GRB okhuliswe ngobushushu uhambelana ne-I-ASTM A106umgangatho, apho "GR.B" ibonisa ukuba umgangatho wayo wezinto ezibonakalayo ngu-B. Iimpawu zayo eziphambili zezi:

1. Iipropati Ezibalaseleyo Zoomatshini: Emva kokwandiswa okushushu kunye nokulungiswa okulandelayo, umbhobho kufuneka uhlangabezane neemfuno zepropati yoomatshini ze-ASTM A106 GR.B, kunye namaxabiso aqhelekileyo amandla okutsalwa≥I-415 MPa kunye namandla okukhupha≥I-240 MPa, idibanisa amandla amahle kunye ne-plasticity ethile.

2. Ubushushu obunokuthenjwa kunye nokuxhathisa uxinzelelo: Yenzelwe ngokukodwa inkonzo yobushushu obuphezulu kunye noxinzelelo oluphezulu. Igcina amandla aphezulu kumaqondo obushushu aphezulu (umz., ukuya kuthi ga kwi-450 degrees).°C), nto leyo eyenza ukuba ifaneleke kwiindlela zokuhambisa izinto ezifana nomphunga kunye neoyile/igesi eshushu kakhulu.

3. Ukuguquguquka Okulungileyo Kobukhulu kunye Nokusebenza Kakuhle Kweendleko: Inkqubo yokwandisa eshushu inokuvelisa iipayipi ezahlukeneyo ezigqityiweyo ezinobubanzi obukhulu ezivela kwiinkcukacha ezifanayo zombhobho womama, igqitha imida yomthamo weemibhobho ezinkulu ezingenamthungo. Ingabizi kakhulu kwaye iguquguquka ngakumbi ekuveliseni iipayipi ezinkulu ezinobubanzi obukhulu, ezinodonga oluqinileyo xa kuthelekiswa neepayipi ezinkulu ezingenamthungo ezijikeleziweyo ngqo ezishushu, ikwanciphisa amaxesha okuhambisa.

4. Indalo Engashukumiyo Egcinwe Ingenamthungo: Nangona isetyenzwa okwesibini, umbhobho ogqityiweyo uhlala ungenamthungo ngokubanzi, uphepha iindawo ezibuthathaka ezinxulumene nee-welds, nto leyo ekhokelela ekuqhubekeni okuhle.

3. IiNdawo eziPhambili zoSicelo

Ukusebenzisa ezi mpawu zingasentla, iipayipi ezishushu ze-A106GRB zisetyenziswa kakhulu kwezi:

•Iinkqubo zeBoiler zeZityalo zoMbane: Kwiindawo ezinobushushu obuphezulu kunye noxinzelelo oluphezulu lwemigca ephambili yomphunga kunye nokufudumala kwakhona imigca yomphunga.

•Ishishini lePetrochemical: Iipayipi zenkqubo yobushushu obuphezulu kwiindawo zokucocisa, kwizityalo zeekhemikhali, kwiipayipi zesithando se-pyrolysis, njl.

•Iinkqubo zokufudumeza: Imigca ephambili yokuhambisa amanzi ashushu ashushu kakhulu kwiinkqubo zokufudumeza zesithili.

•Amanye amaCandelo oShishino: Izixhobo ezahlukeneyo zoshishino ezidibanisa imibhobho ezifuna ukumelana nobushushu obuphezulu kunye noxinzelelo.

4. Isishwankathelo seeNzuzo eziPhambili

Xa kuthelekiswa nemibhobho yendabuko edityanisiweyo yomthungo omde okanye imibhobho engenamthungo ngokweemfuno ezigqithisileyo, iingenelo zemibhobho enwetshiweyo eshushu ye-A106GRB zezi:

•Ibhalansi "Ububanzi obukhulu" kunye "Nomthungo": Ibonelela ngesisombululo esithembekileyo kwiipayipi ezinkulu ezingenamthungo.

•Ukuthobela Ukusebenza, Ulawulo Lomgangatho: Iinkqubo zonyango lobushushu ezivuthiweyo ziqinisekisa ukuba iipropati zoomatshini kunye nesakhiwo se-microstructure ziyahlangabezana okanye zidlula iimfuno ezisemgangathweni.

•Ixabiso Eliphezulu Elipheleleyo: Ixabiso eliphantsi kwaye iguquguquka kwimveliso kwiindidi ezithile zobukhulu xa kuthelekiswa nemibhobho emikhulu engenamthungo eqhutywa ngokupheleleyo eshushu eqengqelekayo enemilinganiselo efanayo.

•Umthamo woXinzelelo oluPhezulu kunye noKhuseleko: Isakhiwo esingenamthungo siphepha ukuwelda okude, sinika ukufana ngakumbi phantsi koxinzelelo olujikelezayo, olufanele iimeko ezinzima.

Umbhobho oshushu we-A106GRB yimpumelelo ebalulekileyo kubuchwepheshe banamhlanje bokwenziwa kwemibhobho yentsimbi. Uzalisekisa ngempumelelo imfuno yemarike ngaphaya komda ophezulu wemigangatho yemibhobho eshushu eqengqelekayo ngelixa ugcina ukhuseleko kunye nokuthembeka kwemibhobho ethambileyo. Ekwakhiweni kwamashishini abalulekileyo kuqoqosho lwesizwe, njengamandla kunye neekhemikhali zepetrochemicals, ukukhethwa ngokuchanekileyo kwemibhobho eshushu ye-A106GRB ehambelana nemigangatho kubaluleke kakhulu ekuqinisekiseni ukusebenza okukhuselekileyo, okuzinzileyo, nokunoqoqosho kwexesha elide kweenkqubo zemibhobho. Ngexesha lokukhetha, iziqinisekiso zenkqubo yomenzi, inkqubo yolawulo lomgangatho, kunye neengxelo zokuhlolwa kwemveliso kufuneka zihlolwe ngokungqongqo ukuqinisekisa ukuthotyelwa ngokupheleleyo kweenkcukacha ezisemgangathweni ze-ASTM A106.
