ʻO ke kuleana o nā pahu hoʻopaʻa ulia pōpilikia i nā pahu mālama LPG
Ka lā: Dec 29, 2019
Ka loina hana o ka pahu hopu pilikia nopahu hoʻopaʻa kinoea liquefied
Ua kapa ʻia hoʻi ka valve pani hoʻopaʻa ulia pōpilikia. ʻO ia hoʻi, e pani ʻia a wehe koke ʻia ka valve inā loaʻa nā hanana i manaʻo ʻole ʻia e pale aku i nā pōʻino. Hiki ke koho ʻia ka valve cut-off pilikia mai ka uila, pneumatic a me ka hydraulic e like me ke kumu mana.
ʻO nā koi no ka hoʻokomo ʻana i nā pahu hoʻopaʻa pilikia no ka pahu mālama kinoea wai wai
E like me ke kūlana aupuni GB50160 "Code for Fire Protection Design of Petrochemical Enterprises" a me ka petrochemical standard SH3136 "Code for Safety Design of Liquefied Hydrocarbon Spherical Storage Tanks", pono e hāʻawi ʻia nā kīwaha pani pani ʻana no ka inlet wai a me ka puka o nā pahu mālama baluna LPG. Wahi a Sinopec's "Design Regulations for the Selection of Emergency Shut-off Valves for Liquefied Hydrocarbon Liquefied Gas Storage Tanks", ua hoʻokomo pono ʻia nā kīwaha hoʻopaʻa pilikia ma nā paipu inlet a me waho o nā pahu mālama LPG. A ʻo ka valve on-off no ka ʻoki ʻana i ka pilikia a me ka hoʻokaʻawale ʻana i nā mea puhi ahi a me nā mea ʻawaʻawa.
I ka wā o ka pae wai o kapahu waihona LPGhiki a ʻoi aku paha ma mua o ka palena kiʻekiʻe o ka wai, hiki ke hoʻohana ʻia ka pahu hoʻopaʻa pilikia e pale aku i nā mea mai ke kahe ʻana o ka pahu. ʻAʻole pono e hoʻokomo ʻia nā mea ʻokoʻa ʻē aʻe mai ka pahu hoʻopaʻa ulia pōpilikia a i ka nozzle pahu pahu pahu wai wai koe wale no ka paipu, a e hoʻokō ka spacing i nā koi o ka hoʻokomo ʻana i ka paipu, ka mālama ʻana a me ke kaʻina hana. 
Pono o ka hoʻokomo ʻana i ka pahu hoʻopaʻa ulia pōpilikia no ka pahu mālama LPG
Me ka ulu nui ʻana o nā pōʻino hana palekana i ka ʻoihana petrochemical i nā makahiki i hala iho nei, ʻo ka hoʻohana ʻana i ke kinoea liquefied petroleum ma ke ʻano he kumu weliweli ka mea i hoʻonui nui ʻia. No ka hōʻoia ʻana i ka hana palekana a me ke kaiapuni o ke kinoea liquefied petroleum, pono nā ʻāpana kūpono e hoʻoheheʻe i ke kinoea liquefied hydrocarbon. E hoʻoikaika ʻia ka ʻenehana palekana wahi mālama. Ma ke ʻano he ʻenehana palekana, pono ia e hoʻopili i ka valve pani ʻana i ka pilikia ma nā wahi i puhi ʻia a pahū a hoʻopili i nā kumu nui o ka pōʻino, i mea e hōʻemi ai i ka pōʻino i lawe ʻia e nā kumu e like me ka hana pipeline, ka hana hewa kanaka a me nā hoʻololi o waho. Ma kēia mea, ua hana nā keʻena pili i nā lula koi.

ʻatikala hope loa:
E hoʻouna i kāu nīnau
ʻAʻole mākou e hāʻawi wale i kahi huahana maikaʻi, akā hāʻawi pū kekahi i ka lawelawe kiʻekiʻe. Inā makemake ʻoe i kā mākou huahana,
hiki iā ʻoe ke hoʻokaʻaʻike mai iā mākou ma kēia mau ala.
