I-X60 Line Pipe, unyango lobushushu boMphezulu lwahlulwe lwaziindidi ezimbini, olunye lunyango lobushushu bekhemikhali, olunye lucima umphezulu kunye nonyango lobushushu, indlela yovavanyo lobulukhuni ngolu hlobo lulandelayo:

[1] Unyango lobushushu bekhemikhali bombhobho weX60
-- Unyango lobushushu lwekhemikhali kukwenza umphezulu wetyhubhu ye-X60 ingene kwi-athomu enye okanye ezininzi zeekhemikhali, ukuze kutshintshe ukwakheka kweekhemikhali, ukwakheka kunye neempawu zomphezulu wetyhubhu ye-X60.Emva kokucima kunye nobushushu obuphantsi bobushushu, umphezulu wombhobho we-X60 unobulukhuni obuphezulu, ukuxhathisa ukunxiba kunye namandla okudibana nokudinwa, kwaye umbindi wombhobho we-X60 unamandla aphezulu kunye nokuqina.

-- Ezona parameters zobugcisa zonyango lwekhemikhali yobushushu bombhobho X60 bubunzulu bomaleko oqina kunye nokuqina komphezulu.Ubunzulu bomaleko oqina kufuneka buvavanywe yi vickers hardness tester.Linganisa umgama ukusuka kumphezulu wombhobho we-X60 ukuya kwindawo apho ukuqina kwehla ukuya kwi-50HRC.Obu bubunzulu obusebenzayo bokwenza lukhuni unyango lwemichiza yobushushu bovavanyo lwetyhubhu ye-X60 yomphezulu wokuvavanya ubulukhuni kunye nokuqina komphezulu wonyango lobushushu ukuqina kokubhaqwa kombhobho weX60, unokusebenzisa umvavanyi wobulukhuni bevickers, umvavanyi wobulukhuni be-rockwell okanye umvavanyi wobulukhuni be-rockwell ukuvavanya, kuphela Ubukhulu be-nitriding engqindilili ebhityileyo, ngokuqhelekileyo ingabi ngaphezu kwe-0.7 mm, ngoko ayinakuphinda isebenzise umvavanyi wobulukhuni be-rockwell, i-Microhardness tester ingasetyenziswa.

[2] X60 umphezulu wemibhobho yokucima kunye nonyango lobushushu obushushu
-- Ukucima umphezulu kunye nobushushu bonyango lobushushu ngokuqhelekileyo luqhutywa ngokufudumeza kwe-induction okanye ukufudumeza ilangatye.Ezona parameters zobugcisa bubunzima bomphezulu, ubulukhuni bendawo kunye nobunzulu obusebenzayo bomaleko.Umvavanyi wobulukhuni beVickers unokusetyenziselwa uvavanyo lokuqina, i-rockwell okanye umvavanyi wobulukhuni be-Rockwell.Ukhetho lwamandla ovavanyo (isikali) lunxulumene nobunzulu bomaleko wokuqina osebenzayo kunye nokuqina komphezulu wombhobho we-X60.Zintathu iindidi zobunzima beemitha ezibandakanyekayo.

Umvavanyi wobulukhuni beVickers yindlela ebalulekileyo yokuvavanya ubulukhuni bomphezulu wombhobho wombhobho we-X60 ophathwe ubushushu.Inokusebenzisa i-0.5 ~ 100kg amandla okuvavanya ukuvavanya umaleko wokuqina womphezulu obhityileyo njenge-0.05mm.Ukuchaneka kwayo kokona kuphezulu, kwaye iyakwazi ukwahlula umahluko omncinci wokuqina komphezulu wombhobho weX60 ophathwe ubushushu.Ukongeza, ubunzulu bomaleko obuqinileyo obusebenzayo buphinda bulinganiswe yi-vickers umvavanyi wobulukhuni, ngoko ke kuyimfuneko ukuxhobisa umvavanyi wobulukhuni beVickers kwiiyunithi eziqhuba unyango lobushushu bomphezulu okanye zisebenzise inani elikhulu lomphezulu womsebenzi wonyango wobushushu.

-- Umvavanyi wobulukhuni beSurface Rockwell ukwalungele kakhulu ukuvavanya ukuqina kombhobho wombhobho weX60 oqinileyo.Kukho izikali ezithathu zomvavanyi wobulukhuni beRockwell onokuthi ukhethe kuwo.Inokuvavanya iintlobo ngeentlobo zemigca eqinileyo yeX60 enobunzulu obusebenzayo bokuqina obungaphezulu kwe-0.1mm.Nangona ukuchaneka komphezulu we-Rockwell hardness tester ungekho phezulu njenge-vickers hardness tester, unokuhlangabezana neemfuno njengendlela yokuvavanya ulawulo lomgangatho kunye nokuhlolwa kokuhambelana kwizityalo zonyango lobushushu.Ngaphezu koko, nayo ineempawu zokusebenza ezilula, ukusetyenziswa olulula, ixabiso eliphantsi, umlinganiselo okhawulezayo, kwaye inokufunda ngokuthe ngqo ixabiso lobulukhuni, njl uvavanyo olutshabalalisayo.Oku kubaluleke kakhulu kwimizila yokwenziwa kwemibhobho ye-X60 kunye nokuveliswa koomatshini.

Umvavanyi wobulukhuni be-Rockwell unokusetyenziswa xa umaleko wokuqina womphezulu ungqindilili.Xa ubukhulu bomaleko obunzima bonyango lobushushu buyi-0.4 ~ 0.8mm, isikali se-HRA singasetyenziswa, xa ubukhulu bomaleko obunzima bungaphezu kwe-0.8mm, isikali se-HRC sinokusetyenziswa.

-- Vickers, Rockwell kunye ne-Surface Rockwell ubulukhuni amaxabiso anokuguqulwa ngokulula abe umgangatho, umzobo okanye amaxabiso afunekayo obunzima bomsebenzisi.Iitheyibhile zoguqulo ezihambelanayo zinikwe kwimigangatho yamazwe ngamazwe ISO, American standard ASTM kunye Chinese standard GB/T.

[3] Unyango lobushushu bendawo
-- Ukuba ubulukhuni bendawo bendawo bufuneka ukuba buphakame, unyango lokucima ukushisa kwendawo lunokwenziwa ngokufudumeza kwe-induction kunye nezinye iindlela.Imibhobho enjalo ye-X60 idla ngokufuna ukuphawula indawo yokucima ubushushu bokucima unyango lwengingqi kunye nexabiso lobulukhuni bendawo kumzobo.Uvavanyo lokuqina kombhobho we-X60 luya kwenziwa kwindawo echongiweyo.Isixhobo sokuvavanya ubulukhuni kunokusebenzisa umvavanyi wobulukhuni be-Rockwell, uvavanyo lwexabiso lobulukhuni lwe-HRC, olufana nonyango lobushushu lokuqina lomaleko alunzulu, lunokusebenzisa umvavanyi wobulukhuni be-Rockwell, uvavanyo lwexabiso lobulukhuni lwe-HRN.
