3pe paipu kila anticorrosion

3pe paipu kila anticorrosionpaipu kila ʻole, paipu kila wiliwilialsaw paipu kila. Hoʻohana nui ʻia ke ʻano ʻekolu-layer o ka polyethylene (3PE) anticorrosion coating i ka ʻoihana pipeline petroleum no kona kūpaʻa maikaʻi ʻana, ka wai a me ke kinoea permeability a me nā waiwai mechanical.ʻO kēia hana anti-corrosion e hoʻomaikaʻi nui i ka pale ʻana i ka corrosion o ka paipu kila, i kūpono i nā ʻōnaehana pipeline e like me ka hoʻoili ʻana i ka aila, ka lawe ʻana i ke kinoea, ka lawe wai a me ka lako wela.

ʻO ke ʻano o ka paipu kila anticorrosion 3PE ka papa mua:
Epoxy pauka uhi (FBE):

ʻO ka mānoanoa ma kahi o 100-250 microns.

Hāʻawi i ka hoʻopili maikaʻi a me ke kūpaʻa kino kino, a hui pū ʻia ka ʻili o ka paipu kila.

 

ʻO ka papa ʻelua: binder (Adhesive):

ʻO ka mānoanoa ma kahi o 170-250 microns.

He mea hoʻopaʻa copolymer ia e hoʻopili ai i ka pauka epoxy i ka papa polyethylene.

 

ʻEkolu papa: Polyethylene (PE) uhi:

ʻO ka mānoanoa ma kahi o 2.5-3.7 mm.

Hāʻawi i ka pale mechanical a me kahi papa wai e kūʻē i ka pōʻino kino a me ke komo ʻana o ka wai.

Ke kaʻina hana o ka paipu kila anti-corrosion 3PE
1. lapaʻau ili: hoʻoneʻe ʻia ka ʻili o ka paipu kila a i ʻole ka pana ʻia e wehe i ka ʻōpala, ka ʻili oxidized a me nā mea haumia ʻē aʻe a hoʻomaikaʻi i ka pili ʻana o ka uhi.

2. Hoʻomaʻamaʻa i ka paipu kila: ua wela ka paipu kila i kahi mahana (maʻamau 180-220 ℃) ​​e hāpai i ka hui ʻana a me ka hoʻopili ʻana o ka pauka epoxy.

3. Hoʻopili i ka pauka epoxy: e hoʻoheheʻe i ka pauka epoxy ma ka ʻili o ka paipu kila wela e hana i ka papa mua o ka uhi.

4. E hoʻopili i ka mea hoʻopili: E hoʻopili i ka mea hoʻopili copolymer ma luna o ka uhi paʻa epoxy e hōʻoia i ka paʻa paʻa ʻana me ka papa polyethylene.

5. Ka uhi ʻana o ka polyethylene: Hoʻopili ʻia kahi ʻāpana polyethylene hope ma luna o ka papa hoʻopaʻa e hana i kahi ʻano ʻekolu-papa piha.

6. Hoʻomaʻalili a hoʻōla: Hoʻomaʻalili ʻia ka paipu kila i uhi ʻia a hoʻōla ʻia e hōʻoia i ka hui pū ʻana o nā ʻāpana ʻekolu o ka uhi ʻana e hana i kahi papa anti-corrosion paʻa.

Nā hiʻohiʻona a me nā pono o ka paipu kila anti-corrosion 3PE

1. maikaʻi maikaʻi ka hana anti-corrosion: ʻo ke ʻano ʻekolu-layer coating e hāʻawi i ka pale anti-corrosion maikaʻi loa a kūpono i nā ʻano ʻano paʻakikī e like me ka acidic a me ka alkaline, nā kai moana a pēlā aku.

2. nā waiwai mechanical maikaʻi: ʻo ka papa polyethylene he hopena maikaʻi loa a me ke kūpaʻa friction a hiki ke kū i ka pōʻino kino o waho.

3. ʻO ke kūlana kiʻekiʻe a me ka haʻahaʻa haʻahaʻa: hiki i ka 3PE anticorrosion layer ke mālama i ka hana maikaʻi ma nā wahi wela kiʻekiʻe a me ka haʻahaʻa, a ʻaʻole maʻalahi ka haki a hāʻule.

4. ka lōʻihi o ka lawelawe ʻana: 3PE anti-corrosion steel pipe lawelawe ola a hiki i 50 mau makahiki a i ʻole ka lōʻihi, e hōʻemi ana i ka mālama pipeline a me nā kumukūʻai pani.

5. maikaʻi adhesion: epoxy pauka uhi a me ke kila paipu ili a ma waena o ka paʻa paʻa i ka adhesion ikaika e pale aku i ka uhi mai ka peeling.

 
Nā kahua noi

1. ʻO ka lawe ʻana i ka aila a me ke kinoea: hoʻohana ʻia no ka lawe ʻana i ka ʻaila a me nā pipeline kūlohelohe e pale ai i ka corrosion a me ka leakage.

2. ʻO ka pipeline kaʻa wai: hoʻohana ʻia i ka lako wai o ke kūlanakauhale, ka hoʻoheheʻe wai, ka mālama ʻana i ka wai a me nā ʻōnaehana pipeline wai ʻē aʻe, e hōʻoia i ka palekana o ka maikaʻi o ka wai.

3. pipeline hoʻomehana: hoʻohana ʻia no ka lawe ʻana i ka wai wela i loko o ka ʻōnaehana hoʻomehana kikowaena e pale ai i ka ʻino o ka pipeline a me ka wela.

4. pipeline ʻoihana: hoʻohana ʻia i ka ʻoihana kemika, metallurgy, mana uila a me nā wahi ʻoihana ʻē aʻe o ka pipeline kaʻina, e pale i ka pipeline mai ka ʻinoʻino o ka media.

5. ʻenehana moana: hoʻohana ʻia i nā paipu submarine, nā paepae moana a me nā ʻenehana moana ʻē aʻe, e kūʻē i ka ʻino o ke kai a me nā mea ola kai.
