Māhele Huahana
Ka hoʻokaʻawale ʻana a me ke kuʻi ʻana o ka pahu LPG a me ka pahu LNG
Ka lā: Feb 06, 2020
Pau nā pahu LNGnā pahu mālama cryogenic, i mahele pinepine ia i elua ano:
(1) ʻO ka pahu pahu kiʻekiʻe: ʻo ka ʻaoʻao o loko i hana ʻia me ke kila kila, ʻo ka ʻaoʻao o waho i hana ʻia me ke kila kalapona, a ua hoʻomāmā ʻia ka waena. ʻO ka nui loa o ka pahu pahu hoʻokahi he 150m3, ka mea i hoʻohana ʻia e nā wahi liʻiliʻi LNG gasification ma ka home a ma waho.
(2) ʻO ka pahu pahu hau: e like me ka LPG atmospheric pressure tank, maʻamau ka pahu nui, ʻelua-layer mechanical, hoʻopiha ʻia me nā mea wela wela ma waena, ua hoʻokomo ʻia nā pahu i loko a me waho ma ka pūnaewele, me ka pōʻai hana lōʻihi. Hana ʻia ka ʻaoʻao o loko i ke kila 9Ni. ʻOi aku ka nui o ka pahu wela maʻamau ma mua o 50000m3. E hoʻemi ʻia ka mahana o ka pahu i lalo - 160 ℃. Hoʻohana ʻia ka weld arc submerged no ka weld circumferential a me ka weld horizontal, a ua ʻae ʻia ka weld manual no ka hapa nui o nā welds ʻē aʻe.
Hoʻokaʻawale pahu LPG
(1) He kiʻekiʻe ke kaomi o ka mahana maʻamau a me ke kiʻekiʻe kiʻekiʻe o ka pahu mālama pahu, a ʻo ke ʻano o ka pahu waihona he spherical maʻamau. ʻAʻole ʻoi aku ka nui o ka pahu mālama i ka 10000m3 maʻamau.
(2) Loaʻa ka pahu mālama haʻahaʻa haʻahaʻa a me ke kaomi ʻana i ka lewa ma ke ʻano o ka pahu dome roof. ʻAʻole i kaupalena ʻia ka nui o ka pahu, akā ʻaʻole ma mua o 100000m3. Hoʻolālā ʻia ka pahu mālama haʻahaʻa haʻahaʻa e like me ka papalua-papa, ʻo ka ʻaoʻao o loko i hana ʻia me ke kila haʻahaʻa haʻahaʻa, ʻo ka ʻaoʻao o waho i hana ʻia me ke kila kalapona maʻamau, a hoʻohui ʻia ka mea insulation wela ma waena. Loaʻa iā ia ka mana nui a me ka uku hoʻouna haʻahaʻa.
LPG liquefaction wela maʻamau - 40 ℃, nui propane a me ka butane. ʻO ka mahana liquefaction o LNG ka mea maʻamau - 162 ℃, ka nui o ka methane.
Welding ofpahu waihona LNG
Hana ʻia ka pahu liʻiliʻi me 304 stainless steel, a ʻo ka mea hoʻoheheʻe ʻo ia ka 308L manual welding rod. Hana ʻia nā pahu nui me ke kila 9Ni, hoʻohana ʻia ka wili arc submerged i nā kūlana kuʻi ʻana a me ka transverse e hoʻomaikaʻi i ka pono, a hoʻohana ʻia ka wili lima lima ma nā kūlana ʻē aʻe.
Welding ofpahu waihona LPG
ʻO nā ʻano hana hoʻoheheʻe kinoea e pili ana i ka wiliwili arc manual, ka wiliwili arc submerged, ka wili arc argon tungsten a me ka wiliwili metala arc. Hoʻohana ka weld longitudinal o ka pahu waihona i ka welding manual, a ʻo ka weld circumferential i hoʻopaʻa ʻia i ka wiliwili arc submerged. Hoʻohana nui ʻia kēia mau ʻano wiliwili ʻelua.

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.
