Yintoni endifanele ndiyiqwalasele xa ndihlola iitanki zokugcina ulwelo ezibizwa ngokuba yi-cryogenic liquid?

Ukuhlolwa kwetanki yokugcina ulwelo oluyi-cryogenic kwahlulwe ngokuhlolwa kwangaphandle, ukuhlolwa kwangaphakathi kunye nokuhlolwa okunemiba emininzi. Ukuhlolwa rhoqo kweetanki zokugcina eziyi-cryogenic kuya kugqitywa ngokwemiqathango yobugcisa yokusetyenziswa kweetanki zokugcina.

 Ngokubanzi, uhlolo lwangaphandle lwenziwa kanye ngonyaka, uhlolo lwangaphakathi lwenziwa kanye kwiminyaka emi-3, kwaye uhlolo olunemiba emininzi lwenziwa kanye kwiminyaka emi-6. Ukuba itanki yokugcina enobushushu obuphantsi inobomi benkonzo obungaphezulu kweminyaka eli-15, uhlolo lwangaphakathi nolwangaphandle lwenziwa rhoqo emva kweminyaka emibini. Ukuba ubomi benkonzo buyiminyaka engama-20, uhlolo lwangaphakathi nolwangaphandle lwenziwa ubuncinane kanye ngonyaka.

1. Uhlolo lwangaphakathi

 1). Nokuba kukho ukubola okubolayo kumphezulu wangaphakathi kunye netanki yokugcina uqhagamshelo lwe-manhole, kwaye nokuba kukho imingxunya kumthungo wokuwelda, indawo yokuguquka kwentloko okanye ezinye iindawo apho uxinzelelo luxinene khona;

 2). Xa kukho ukugqwala kwiindawo zangaphakathi nezangaphandle zetanki, kufuneka kwenziwe imilinganiselo emininzi yobukhulu bodonga kwiindawo ezirhanelwayo. Ukuba ubukhulu bodonga obulinganisiweyo bungaphantsi kobukhulu bodonga obuncinci obucwangcisiweyo, kufuneka kuhlolwe kwakhona ukuqinisekiswa kwamandla, kwaye kucetyiswe ukuba ingaqhubeka isetyenziswa na kwaye uxinzelelo oluphezulu oluvumelekileyo lufanele lubekwe phambili;

 3). Xa udonga lwangaphakathi lwetanki luneziphene ezifana nokususwa kwekhabhohayidreyithi, ukubola koxinzelelo, ukubola phakathi kwegranular kunye nokuqhekeka kokudinwa, kufuneka kwenziwe uvavanyo lwe-metallographic kunye nokulinganiswa kobunzima bomphezulu, kwaye kufuneka kungeniswe ingxelo yokuhlolwa.

2. Uhlolo lwangaphandle

 1). Jonga ukuba umaleko wokulwa nokugqwala, umaleko wokugquma kunye nepleyiti yegama lesixhobo setanki yokugcina ziphelele na, kwaye ingaba izixhobo zokhuseleko kunye nezixhobo zolawulo zigqibelele, zinobuthathaka kwaye zithembekile na;

 2). Nokuba kukho imifantu, ukuguquguquka, ubushushu obugqithisileyo bendawo, njl.njl. kumphezulu ongaphandle;

 3). Nokuba umthungo wokuwelda wombhobho odibanisayo kunye nezinto ezibangela uxinzelelo ziyavuza, nokuba iibholithi zokubopha azikho, nokuba isiseko siyatshona, siyathambekela okanye ezinye iimeko ezingaqhelekanga.

3, Uhlolo olupheleleyo

 1). Yenza uhlolo olungenamonakalo kwi-weld okanye kwi-shell ephambili, kwaye ubude bendawo yokujonga kufuneka bube yi-20% yobude bonke be-weld;

 2). Emva kokuphumelela kuhlolo lwangaphakathi nolwangaphandle, yenza uvavanyo lwe-hydraulic ngokuphindwe kayi-1.25 uxinzelelo loyilo lwetanki yokugcina kunye novavanyo lomoya olungenamoya kuxinzelelo loyilo lwetanki yokugcina. Kwinkqubo yohlolo engentla, itanki yokugcina kunye nee-welds zazo zonke iindawo azinawo amanzi avuzayo, kwaye itanki yokugcina ayinawo uguquko olungaqhelekanga olubonakalayo njengoko kufanelekile;

 Emva kokuba kugqitywe ukuhlolwa kwetanki yokugcina enobushushu obuphantsi, kufuneka kwenziwe ingxelo ngokuhlolwa kwetanki yokugcina, ebonisa iingxaki kunye nezizathu ezingasetyenziswa okanye ezingasetyenziswa kodwa ezifuna ukulungiswa nezingenakusetyenziswa. Ingxelo yokuhlolwa kufuneka igcinwe kwifayile ukuze kugcinwe ulondolozo kunye nokuhlolwa kwixesha elizayo.
