Ka Ike ana o na hiohiona o na pahu waiho laina laina

I loko o nā ʻoihana kemika, meaʻai, a me nā lāʻau lapaʻau, hoʻohana nui ʻia nā pahu mālama laina ma muli o ko lākou kūpaʻa maikaʻi a me ka palekana. Hoʻokumu pinepine ʻia kēia ʻano pahu waihona me ka metala a i ʻole ka ʻili palaki a me kahi mea lining, ʻaʻole hiki ke pale wale i ke kaomi o waho, akā hoʻokaʻawale maikaʻi hoʻi i ke ʻano o loko e pale ai i ka pollution a i ʻole corrosion. E kālailai kēia ʻatikala i nā hiʻohiʻona nui o nā pahu hoʻopaʻa laina laina mai ke ʻano o nā hiʻohiʻona hiʻohiʻona e kōkua i nā mea hoʻohana e ʻike maikaʻi a koho i nā huahana kūpono.

ʻO ke ʻano o ka pūpū: paʻa a paʻa

Hana ʻia ka pūpū o kahi pahu mālama laina i nā mea e like me ke kila kalapona, ke kila kila, a i ʻole fiberglass e hōʻoia i ka ikaika a me ka paʻa o ka hale holoʻokoʻa. Mai ka hiʻohiʻona, he pālahalaha a maʻalahi ka ʻili o ka pūpū, ʻaʻahu like nā welds, ʻaʻohe hewa i ʻike ʻia. Hiki ke hoʻopaʻa ʻia a pena ʻia paha kekahi mau pahu i mea e hoʻoikaika ai i ka pale ʻana a i ʻole e hoʻomaikaʻi i ka nani. Hoʻopili maʻamau ka hoʻolālā ʻana o ka pūpū me nā kūlana honua e like me ASME, API, a me nā mea ʻē aʻe, e hōʻoia i ka hana palekana ma lalo o ke kaomi kiʻekiʻe a i ʻole ka pōʻino.

Laina mea: nā koho like ʻole

Aia ke kumu o ka pahu ho'opa'a laina i loko o kona papa lining. ʻO nā mea maʻamau ka polyethylene (PE), polypropylene (PP), fluoroplastics (e like me PTFE), a me nā mea ʻē aʻe. He kūpaʻa kemika maikaʻi kēia mau mea a hiki ke hoʻokaʻawale maikaʻi i nā media e like me nā waikawa, alkalis, a me nā mea hoʻoheheʻe. Mai ka hiʻohiʻona, ʻoluʻolu a palahalaha ka papa lining, me ka ʻole o nā ʻōpū a me nā māwae, a ua hana maikaʻi ʻia nā hui e hōʻoia i ka sila. Hiki paha i kekahi -huehu pahu waihona ki'eki'e ke ho'ohana i ka -mea ho'olālā lining no ka ho'oikaika 'ana i ka lō'ihi a me ka -permeability.

Manholes a me nā paipu: nā hana a me ka nani

Hoʻolako pinepine ʻia nā pahu mālama laina me nā manholes, nā paipu, nā flanges a me nā mea pono ʻē aʻe no ke komo ʻana a me ka puka ʻana, ka ʻike a me ka mālama ʻana i ka waena. ʻO ka hoʻolālā hiʻohiʻona o kēia mau ʻāpana e pili ana i ka hana. No ka la'ana, ho'ohana ma'amau ka uhi manhole i ka -ho'olālā pahe'e, a he palahalaha ka pilina paipu, he mea ma'alahi no ka ho'ohui 'ana i nā paipu. Hiki paha i kekahi mau pahu waihona ke hōʻailona i nā laina pae wai a i ʻole nā ​​hōʻailona hōʻailona palekana ma ka pūpū e hoʻomaʻamaʻa i ka hana a ka mea hoʻohana.

Lapaʻau ʻili: pono a nani hoʻi

I mea e hoʻomaikaʻi ai i ka lōʻihi a me ka maikaʻi o ke ʻano o ka pahu mālama, hana maʻamau nā mea hana i ka hana kūikawā ma ka ʻili. No ka laʻana, hiki ke galvanized, sprayed a anodized ka pūpū metala e hoʻoikaika ai i ka pale ʻana i ka corrosion; hiki ke hoʻopololei ʻia a i ʻole ka hau e hoʻonui ai i ka paʻi a me nā hopena ʻike.

ʻO nā hiʻohiʻona hiʻohiʻona o nā pahu mālama laina ʻaʻole wale e hōʻike i ke kiʻekiʻe o kā lākou hana hana, akā pili pū kekahi i kā lākou hana a me ke ola. Hiki i ka hoʻomaopopo ʻana i kēia mau hiʻohiʻona ke kōkua i nā mea hoʻohana e hana i nā koho ʻike i ka wā e kūʻai ai a e hōʻoia i ka paʻa a palekana nā pahu i ka -hoʻohana lōʻihi.
