No ke aha e koho ai i ka kiwikā nānā? He aha nā ʻano kiwikā i loaʻa?

Ua lilo mālie nā kiwikā nānā i mea koʻikoʻi i nā mea hoʻokomo paipu a me nā kiwikā i ka hoʻolālā paipu o kēia manawa. Hāʻawi lākou i nā hōʻoia palekana no ka paipu holoʻokoʻa a hōʻemi pololei i nā pilikia palekana a me nā kumukūʻai no ka ʻōnaehana paipu holoʻokoʻa.

Hoʻohana ʻia nā kiwikā nānā e nānā i nā kūlana hana i ka manawa maoli, hoʻoponopono i nā pilikia a hōʻoia i ka palekana. ʻO nā kiwikā nānā i hoʻohana pinepine ʻia (e like me nā aniani ʻike pololei a me nā ʻōkuhi kahe) ʻaʻole lākou e kāohi i ke kahe ponoʻī, akā hāʻawi i kahi puka makani ʻike ma ka pipeline.

ʻO nā pono o ka nānā ʻana i nā valves e hōʻike nui ʻia ma nā ʻano ʻekolu:

1. E nānā pono i ke kahe ʻana o ke kahe, ke kala a me ka turbidity o ka wai, ke kinoea, ka mahu a me nā mea ʻē aʻe i loko o ka pipeline.
2. Ke ʻike ʻia ke kahe kūpono ʻole o ke kahe i loko o ka ʻōnaehana, ke ālai ʻia a i ʻole ke kahe ʻole ʻana, hiki ke hoʻoholo koke ʻia ke kumu ma o ka valve nānā ʻana inā paha ma muli o ka paʻa ʻana o ka valve ponoʻī, ka hāʻule ʻana o ke kumu valve, a i ʻole nā ​​​​pilikia i loko o ka pipeline o uka.
3. E hōʻoia i ka hana palekana o ka ʻōnaehana. I nā wahi weliweli e like me nā hale hana kemika, hoʻohana ʻia ia e nānā i nā mea wela kiʻekiʻe, ʻōpala loa a me nā mea hoʻoheheʻe maʻalahi e pale aku i nā pōpilikia palekana i hoʻokumu ʻia e nā pae wai wahaheʻe a i ʻole nā ​​​​​​mea ālai.

Hoʻohana ʻia nā kiwikā nānā like ʻole ma nā wahi hana like ʻole. Hana ʻia me ke kila kalapona, kūpono lākou no nā mea maʻamau e like me ka wai, ka mahu, a me ka ʻaila, akā ʻaʻole kūpaʻa i ka pala.

Mea kila kila

ʻO ia ka mea kūpaʻa i ka corrosion a kūpono loa no nā ʻano pāpaho corrosive like ʻole.

Ke kila kila a me nā mea kila kila kūikawā

He kūpono no nā ʻano ʻino e like me ke kiʻekiʻe o ka mahana, ke kaomi kiʻekiʻe, a me ka pala ikaika.

Hoʻopaʻa ʻia me ka palakiko a i ʻole ka fluorine

Kūpono no nā mea hoʻoheheʻe ʻino loa e like me nā waikawa ikaika a me nā alkalis ikaika.

So

• Pāpaho ʻino ʻole: He koho ke kila kalapona a he kūpono hoʻi ke kumukūʻai.
• Nā mea ʻino maʻamau: makemake ʻia ke kila kila 304 a i ʻole 316.
• Mea ʻino loa a mea hoʻolaha kūikawā paha: Pono nā kiwikā i uhi ʻia i ka fluorine a i ʻole nā ​​​​mea hoʻohuihui kūikawā.
• Pāpaho wela kiʻekiʻe a i ʻole ka wela haʻahaʻa: Pono e koho ʻia ke kila wela kiʻekiʻe kūikawā a i ʻole ke kila wela haʻahaʻa.
