Yintoni endifanele ndinikele ingqalelo kuyo xa ndihlola iitanki zokugcina ulwelo lwe-cryogenic?

Ukuhlolwa kwetanki yokugcina ulwelo lwe-Cryogenic yahlulwe kuhlolo lwangaphandle, ukuhlolwa kwangaphakathi kunye nokuhlolwa kwezinto ezininzi.Ukuhlolwa kwexesha leetanki zokugcina i-cryogenic kuya kumiselwa ngokwemiqathango yobugcisa bokusetyenziswa kweetanki zokugcina.

 Ngokuqhelekileyo, ukuhlolwa kwangaphandle ubuncinane kanye ngonyaka, uhlolo lwangaphakathi ubuncinane kanye emva kweminyaka emi-3, kwaye uhlolo olunamacandelo amaninzi ubuncinane kanye kwiminyaka emi-6.Ukuba itanki yokugcina iqondo lokushisa eliphantsi linobomi benkonzo engaphezulu kweminyaka eyi-15, ukuhlolwa kwangaphakathi nangaphandle kuya kwenziwa rhoqo kwiminyaka emibini.Ukuba ubomi benkonzo buyiminyaka engama-20, ukuhlolwa kwangaphakathi nangaphandle kuya kwenziwa ubuncinane kanye ngonyaka.

1. Ukuhlolwa kwangaphakathi

 1).Nokuba kukho ukunxiba okumdaka kumphezulu wangaphakathi kunye netanki yokugcina unxibelelwano lomngxuma, kwaye nokuba kukho iintanda kwi-welding seam, indawo yokutshintsha kwentloko okanye ezinye iindawo apho uxinzelelo lugxininiswe;

 2).Xa kukho umhlwa kwindawo yangaphakathi nangaphandle yetanki, imilinganiselo yobuninzi beendonga kufuneka yenziwe kwiindawo ezikrokrelekayo.Ukuba ubungakanani bodonga olulinganisiweyo bungaphantsi kobunzima obuyilwe bodonga oluncinci, ukuqinisekiswa kwamandla kufuneka kuhlolwe kwakhona, kunye neengcebiso malunga nokuba ingaqhubeka isetyenziswe kwaye uxinzelelo oluphezulu oluvumelekileyo kufuneka lubekwe phambili;

 3).Xa udonga lwangaphakathi lwetanki luneziphene ezinje nge-decarburization, i-corrosion yoxinzelelo, i-intergranular corrosion kunye neentanda zokudinwa, ukuhlolwa kwe-metallographic kunye nomlinganiselo wobunzima bomphezulu kuya kwenziwa, kwaye ingxelo yokuhlola iya kufakwa.

2. Ukuhlolwa kwangaphandle

 1).Khangela ukuba umaleko wokuchasana nomhlwa, umaleko wokugquma kunye ne-nameplate yesixhobo setanki yokugcina icocekile, nokuba izincedisi zokhuseleko kunye nezixhobo zokulawula ziphelele, zinovakalelo kwaye zithembekile;

 2).Ingaba kukho ukuqhekeka, ukuguqulwa, ukushisa kwendawo, njl njl kumphezulu wangaphandle;

 3).Ingaba i-welding seam yombhobho odibanisayo kunye namacandelo oxinzelelo ayavuza, nokuba iibholiti zokuqinisa ziqinile, nokuba isiseko siyatshona, sithambekile okanye ezinye iimeko ezingaqhelekanga.

3, Gqibezela uhlolo

 1).Yenza uhlolo olungonakali kwi-weld engundoqo okanye iqokobhe, kwaye ubude bendawo yokutshekisha iya kuba ngama-20% obude bebonke beweld;

 2).Emva kokuphumelela ukuhlolwa kwangaphakathi nangaphandle, yenza uvavanyo lwe-hydraulic ngamaxesha e-1.25 uxinzelelo loyilo lwetanki yokugcina kunye novavanyo olungenamoya kwixinzelelo loyilo lwetanki yokugcina.Kwinkqubo yokuhlola engentla, itanki yokugcina kunye ne-welds yazo zonke iindawo azikho ukuvuza, kwaye itanki yokugcina ayinayo i-deformation ebonakalayo engaqhelekanga njengoko ifanelekile;

 Emva kokuhlolwa kwetanki yokugcina iqondo lokushisa eliphantsi ligqityiwe, kufuneka kwenziwe ingxelo ekuhlolweni kwetanki yokugcina, ebonisa iingxaki kunye nezizathu ezinokuthi zisetyenziswe okanye zingasetyenziselwa kodwa zifuna ukulungiswa kwaye azikwazi ukusetyenziswa.Ingxelo yohlolo kufuneka igcinwe efayilini ukulungiselela ukugcinwa nokuhlolwa kwixesha elizayo.
