Nā pōmaikaʻi o nā paipu wai PVC:
⑴ He tensile maikaʻi a me ka ikaika compressive.
⑵ Haʻahaʻa wai kūʻē:ʻO ka pā o UPVCʻoluʻolu loa nā paipu a he liʻiliʻi ke kūʻē i ka wai. ʻO 0.009 wale nō ka helu o kona ʻāʻī. Eia kekahi, hiki ke hoʻonui ʻia ka mana hoʻoili wai e 20% i hoʻohālikelike ʻia me nā paipu hao hao o ke anawaena like a me 40% i hoʻohālikelike ʻia me nā paipu paʻa.
⑶ ʻOi aku ka maikaʻi o ka pale ʻana i ka corrosion a me ke kūʻē kemika: ʻO nā paipu UPVC he maikaʻi ka waika a me ka pale alkali a me ke kūpaʻa ʻino. ʻAʻole pili lākou i ka maʻa a me ka lepo PH, no laila ʻaʻole pono ka mālama anti-corrosion i ke kau ʻana i nā paipu.
⑷ Paʻa wai maikaʻi: ʻO ka hoʻokomo ʻana i nā paipu UPVC he paʻa wai maikaʻi ka pili ʻole inā pili ʻia e ka hoʻopaʻa ʻana a i ʻole nā apo lāʻau.
⑸ ʻAi-nahu: No ka mea ʻaʻole kumu o ka meaʻai nā paipu UPVC, ʻaʻole lākou e ʻānai ʻia e nā ʻiole.
Nā wahi noi
ʻO nā paipu plastik PVCHoʻohana nui ʻia i nā ʻōnaehana wai hale noho, nā ʻōnaehana wai kūkulu kūlanakauhale, nā ʻōnaehana pipeline wai a me nā ʻōnaehana wai wai. Hiki ke hoʻohana ʻia nā paipu plastik PVC e like me nā paipu hoʻoili mana no nā uea a me nā paipu infusion olakino. Eia kekahi, hiki ke hoʻohana ʻia nā paipu plastik PVC ma lalo o ka lepo e like me nā awa hoʻoheheʻe kinoea ma nā kahua koli lanahu, ma ke ʻano o nā awa hoʻoheheʻe ʻana i lalo, a no ka waiho ʻana i nā paipu i nā lua lanahu lalo. He laula loa kona laula noi.
Hoʻohana nui ʻia nā paipu plastik PVC liʻiliʻi ma ke ʻano he paipu wai hale, hiki ke hoʻohana ʻia nā paipu liʻiliʻi e like me nā paipu wai lepo o ke kūlanakauhale, a ʻo nā mea me ke anawaena nui loa e hiki ke hoʻohana ʻia i paipu wai no ka South-to-North Water Diversion Project. Aia kekahi paipu plastik PVC liʻiliʻi i hiki ke hoʻohana ʻia ma ke ʻano he paipu lawe mana.
Inā huli melemele ka paipu PVC i hana ʻia, pono ʻoe e nānā i ka pilikia o nā lako hana paipu PVC.
1. Inā pilikia ka thermocouple a i ʻole ka peʻahi, e hoʻopau ka pahu i ka wela ma ka ʻāina a lilo ka huahana i melemele, ʻo ia hoʻi, puhi a huli melemele. Pane: E nānā i ka hana pono ʻana o nā thermocouple ma kēlā me kēia wahi o ka barela a inā paha e hana maʻamau nā mea pā ma kēlā me kēia wahi.
2. Inā pa'a ka 'aila kaapuni, 'a'ole hiki ke ho'oku'u 'ia ka wela ku'i o ka wili, no laila e wela loa ka wili a ho'ohehe'e ka mea a lilo i melemele. Pane: E nānā inā lawa ka ʻaila hoʻoili wela o ka wili, inā paha e hana pono ana ka ʻaila ʻaila, a paʻa paha ka paipu aila.
3. I ka hihia o ka wili nui, ua nui ka hakahaka ma waena o ka wili a me ka pahu, a ʻoi aku ka maikaʻi o ka hiki ʻana o ka wili i ka mea, e hoʻihoʻi i ka mea i loko o ka pahu, i mea e wela ai ka mea. no ka manawa lōʻihi i loko o ka barela, ka hopena o ka melemele. Pane: Hiki iā ʻoe ke nānā a hoʻoponopono i ka ʻākea wili a hoʻololi paha i ka wili.
