ʻO ka paipu ʻāwili paʻa paʻa pālua

ʻO ka wehewehe pōkole:

ʻO ka paipu ʻāwīwī palua-pā: he ʻano paipu hou me ka paia o waho annular a me ka paia o loko. Hoʻohana nui ʻia ia no ka hāʻawi ʻana i ka wai nui, ka wai wai, ka hoʻoheheʻe ʻana, ka hoʻokuʻu ʻana i ka wai, ka exhaust, subway ventilation, mine ventilation, irrigation ʻāina mahiʻai a pēlā aku me ke kaomi hana ma lalo o 0.6MPa. He uliuli a ʻeleʻele ka waihoʻoluʻu o ka paia o loko, a e hoʻohana kekahi mau lama melemele.

ʻO ka paipu ʻāwili paʻa paʻa pālua
Hana ʻia ʻo "HDPE (high-density polyethylene) corrugated pipe", "PVC-U (hard polyvinyl chloride) corrugated pipe", "PP (polypropylene) corrugated pipe", etc. e like me nā kumu kumu. , Hoʻopili pū ka extruder o waho, hoʻokahi manawa hoʻoheheʻe, paʻa ka paia o loko, ua hoʻopili ʻia ka pā o waho, a aia kahi ʻāpana o ka paipu plastik ma waena o nā paia o loko a me waho.

Nā hiʻohiʻona o nā paipu corrugated plastic:
1. ʻO keʻano kūʻokoʻa, ka ikaika kiʻekiʻe, ka hoʻopiʻi a me ka hopena hopena.
2. He kūpono ka pilina, hoʻopaʻa maikaʻi ʻia ka hui, ʻaʻohe leakage.
3. ke kaumaha māmā, ka hana wikiwiki a me ke kumu kūʻai haʻahaʻa.
4. ʻOi aku ke ola lawelawe i kanu ʻia ma mua o 50 mau makahiki.
5. ʻO ka polyethylene he polymer hydrocarbon me nā molekala non-polar a kū'ē i kaʻakika a me ka alkali.
6. ʻO nā mea maka he mau mea palekana kaiapuni'ōmaʻomaʻo,ʻaʻohe meaʻawaʻawa, non-corrosive, non-scaling, a hiki ke hana hou a hoʻohana.
7. He ākea ka laulā wela o ka hoʻohana ʻana, ʻaʻole e haki ka paipu i ke kaiapuni o -60 ℃, a ʻo 60 ℃ ka mahana o ka mea lawe.
8. 'O ke kumu kū'ai o ka papahana holo'oko'a, ua like ia me ke ko'iko'i, a he ha'aha'a ka uku hana.
9. ʻAʻole pono ke kahua inā maikaʻi ka maikaʻi o ka lepo.

Noi:
Hoʻohana nui ʻia nā paipu corrugated plastic ma nā wahi he nui e like me lalo
1. ʻO nā paipu hoʻoheheʻe a me ka ea no nā mina a me nā hale;
2. Ka 'enekinia kaona, ka ho'okahe 'ana i lalo o ka honua a me nā paipu wai ho'oha'aha'a ma nā wahi noho;
3. Ka wai a me ka hoʻokahe ʻana i ka mālama wai ʻāina mahiʻai; nā paipu hoʻoheheʻe wai no nā mea kanu hoʻomaʻemaʻe wai a me nā wahi hoʻolei ʻōpala;
4. ʻO nā paipu hoʻoheheʻe kemika a me nā paipu lawe wai kemika a me ka mining;
5. ʻO ka hana holoʻokoʻa o nā luawai nānā pipeline; nā kilomika kiʻekiʻe o nā pipeline i kanu mua ʻia;
6. uwea kiʻekiʻe-voltage, pou a me ke kelepona pale lima lima, etc.
