Paipu wai kila kila
No ke aha e hoʻohana ai i nā paipu wai kila
ʻO ka paipu wai inu kila kila 304 meaʻai-grade wai paipu mea ʻaʻohe mea ʻawaʻawa a maikaʻi ʻole i ke olakino a me ka palekana.ʻO nā mea maikaʻi o nā paipu wai inu kila e pili ana i ka pale ʻana i ke kaiapuni, ka lōʻihi, ka ikaika kiʻekiʻe, ka palekana, a me ka pono.
1. Ka palekana o ke kaiapuni a me ke olakino: ʻO ka paipu wai kila he ʻōmaʻomaʻo, pili i ke kaiapuni, a olakino, ʻaʻole e hoʻoneʻe i nā mea ʻino, kahi e hoʻohaumia ai i ke kumu wai.
2. Ka hopena o ke kahe: ʻO ka paia o loko o ka paipu wai kila he maʻalahi, ʻaʻole maʻalahi ke kau ʻana, ʻaʻole pili i ka kahe wai.
3. Kaʻelemakule: 304 meaʻai māka kuhiliʻole kila 'aʻole rust a makahiki
4. Huna pilikia o ka wai leakage: ʻO ka pilikia huna o ka wai leakage i loko o kuhiliʻole kila paipu wai mea liʻiliʻi, a hiki i ka uʻi kaula pili 'enehana hiki ke hōʻoiaʻiʻo i nā paipu.
5. ʻO ke ola lawelawe: ua hoʻohana ʻia nā paipu wai kila ma mua o 70 mau makahiki, ke ola like me ka hale, ʻaʻole pono ka mālama ʻana i ka wā hope.
6. Pipeline ikaika: kuhiliʻole kila wai paipu mea i kiʻekiʻe ka ikaika, hiki ke pale koke i ke kaomi o 89Mpa, kuhiliʻole kila 'aʻole e rust a makahiki.
7. ʻO ka hiki ke hoʻopaʻa i ke kaomi: ʻO ka wai kila kila he kiʻekiʻe kiʻekiʻe a hiki ke pale aku i ke kaomi 2.5Mpa
8. Pipeline deformation: kuhiliʻole kila wai paipu i ka liʻiliʻi thermal hoʻonui coefficient a ʻaʻole e deform
Nā pōmaikaʻi o ka hoʻohana ʻana i nā paipu wai kila kila
ʻO nā paipu wai kila maikaʻi loa nā paipu wai.E like me ke ana maoli, ma ka laulā, hiki i ke kaomi hana o ka ʻōnaehana paipu wai kila kila ke piʻi aku ma mua o 2.5Mpa.He 1/25 o ka paipu keleawe a me ka 1/4 o ka paipu hao.ʻO kona hopena insulation thermal ka mea maikaʻi loa ma waena o nā paipu metala āpau, a hiki ke hoʻohana ʻia no ka manawa lōʻihi i ka pae wela o -40 ℃ ~ 120 ℃.ʻO ka mahana kiʻekiʻe o ka wai home he 100 ℃.Inā he wela kiʻekiʻe a haʻahaʻa paha, paʻa loa nā waiwai waiwai;a loaʻa iā ia ka ductility maikaʻi a me ka paʻakikī.ʻO ka ikaika kiʻekiʻe o nā paipu wai kila kila e hōʻemi nui i ka hiki ke hoʻoheheʻe ʻia ka wai i hoʻopilikia ʻia e nā ikaika o waho, e hōʻemi nui i ka leakage o ka wai, a hiki i nā kumu wai ke mālama pono a hoʻohana ʻia.
ʻO nā pono o nā paipu wai kila ma mua o nā paipu wai galvanized
ʻO ke kila kila he mea metala.ʻO ke kila kila ʻole ke kila i kū i nā mea hoʻoheheʻe nāwaliwali e like me ka ea, ka mahu, a me ka wai, a me nā mea hoʻoheheʻe kemika e like me ka waikawa, ka alkali, a me ka paʻakai.Ua ʻike ʻia ʻo ia he kila kuhiliʻole waika.
Ma nā hoʻohana pono, kapa pinepine ʻia ke kila kūʻē i ka media corrosive nāwaliwali, a ʻo ke kila kūʻē i ka media chemical corrosion ua kapa ʻia ʻo ka acid-resistant steel.Ma muli o ka ʻokoʻa o ka haku mele ʻana ma waena o nā mea ʻelua, ʻaʻole kū pono ka mea mua i ka corrosion media kemika, ʻoiai ʻo ka mea maʻamau he stainless.ʻO ka pale ʻana i ka corrosion o ke kila kila ma muli o nā mea hoʻohui i loko o ke kila
ʻO nā mea hoʻohui kumu o ke kila kila, ʻo ia ka nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., e hoʻokō i nā koi no ke kūkulu ʻana a me nā waiwai o ke kila kila no nā kumu like ʻole.Hoʻopili maʻalahi ke kila kila e nā ion chloride, no ka mea, he isotopes ka chromium, nickel, a me ka chlorine, a e hoʻololi a hoʻohui ʻia nā isotopes e hana i ke kila kila.
Ke emi nei ka pale ʻino o ke kila kila kila me ka piʻi ʻana o ke kalapona.No laila, he haʻahaʻa ka ʻike kalapona o ka hapa nui o nā kila kila, ʻaʻole i ʻoi aku ka nui ma mua o 1.2%, a ʻoi aku ka haʻahaʻa o ka wc (carbon content) o kekahi mau kila ma mua o 0.03% ( E like me 00cr12).ʻO ka mea hoʻohui nui i ke kila kila ʻo Cr (chromium).Ke hiki wale ka ʻike Cr i kahi waiwai, ʻoi aku ka pale ʻana o ke kila.No laila, he cr (chromium) ka maʻiʻo o ke kila kila ma ka liʻiliʻi loa he 10.5%.Aia i loko o ke kila kila ni, ti, mn, n, nb, mo, si, cu a me nā mea ʻē aʻe.ʻO ke kila kila kekahi o nā mea ikaika loa i nā mea metala kūkulu.Ma muli o ke kila kila maikaʻi ke kūpaʻa ʻana i ka corrosion, hiki iā ia ke mālama mau i ka pono ʻenehana o nā mea hana.Hoʻohui pū ʻia ke kila kila kila Chromium i ka ikaika mechanical a me ka elongation kiʻekiʻe, a ua maʻalahi ka hana a hana i nā ʻāpana e hoʻokō i nā pono o nā mea kālai a me nā mea hoʻolālā.
