Hoʻohana nui ʻia nā paipu kila spiral e like me nā paipu wai a me nā paipu pila. Inā hoʻohana ʻia ka paipu kila no ka hoʻoheheʻe wai, e hana maʻamau ia i ka anti-corrosion ma ka ʻaoʻao o loko a i waho paha. ʻO nā lāʻau lapaʻau maʻamau me ka 3pe anti-corrosion, epoxy coal tar anti-corrosion, a me ka pauka epoxy anti-corrosion. E kali, no ka mea, pilikia ke kaʻina hana epoxy pauda e nā pilikia pili, ʻaʻole i hoʻolaha ʻia ke kaʻina hana epoxy pauda. I kēia manawa, me ka hoʻomohala kūleʻa ʻana o ka hopena phosphating kūikawā no ka hoʻoheheʻe ʻana i ka pauka epoxy, ua lanakila ka pilikia adhesion o ke kaʻina hana epoxy powder dipping no ka manawa mua, a ua hoʻomaka ke ʻano o ka epoxy powder dipping.

Ke kālailai ʻana i nā kumu o ka mānoanoa o ka uhi ʻana i ka corrosion ma luna o nā paipu kila spiral, ʻike ʻia ka mānoanoa like ʻole o ka 3PE spiral steel pipe coatings i ka mānoanoa like ʻole o nā helu hoʻāʻo ma kēlā me kēia ʻaoʻao i puʻunaue ʻia ma ka ʻaoʻao circumferential. ʻAʻohe kānāwai o ka ʻoihana maʻamau SY/T0413-2002 no ka like ʻana o ka mānoanoa. Hōʻike ia i ka waiwai mānoanoa o ka uhi akā koi i ka waiwai mānoanoa o ka uhi ʻaʻole hiki ke emi ma mua o ka waiwai mānoanoa o kahi kiko, ma mua o ka waiwai awelika o nā helu hoʻāʻo lehulehu.

Inā ʻaʻole kūlike ka mānoanoa o ka uhi ʻana i ka wā o ka hoʻopili ʻana o nā paipu kila spiral, ʻaʻole hiki ke hoʻopau ʻia ka mea uhi. ʻO kēia no ka mea i ka wā e hiki ai ka mānoanoa o ka uhi ma ka ʻāpana lahilahi i ka kikoʻī, e ʻoi aku ka mānoanoa o ka ʻāpana mānoanoa ma mua o ka mānoanoa kikoʻī Coating. Eia kekahi, hiki i ka uhi ʻole ʻia ke hana maʻalahi i ka mānoanoa o ka uhi ʻana i ka ʻāpana ʻoi loa o ka paipu kila e hiki ʻole ke hoʻokō i nā kikoʻī. ʻO nā kumu nui o ka mānoanoa like ʻole i ka wā o ke kaʻina hana, ʻo ka hāʻawi ʻana i nā mea pono ʻole a me ke kuʻi ʻana o ka paipu kila. ʻO kahi ala maikaʻi e hoʻomalu ai i ka uhi ʻole ʻana o nā paipu anti-corrosion 3PE ʻo ia ka hoʻoponopono ʻana i nā make extrusion e hana i ka mānoanoa o ka uhi anti-corrosion ma nā wahi like me ka hiki a pale i nā paipu kila kūpono ʻole mai ka uhi ʻia ʻana ma ka pūnaewele.

ʻO nā wrinkle ma ka ʻili o ka uhi: ʻO ka extrusion a me ka wili ʻana o ka mea polyethylene ma luna o ka paipu kila e pono ai ka hoʻohana ʻana i kahi wili silicone. ʻO ka hoʻoponopono kūpono ʻole i ka wā o kēia kaʻina hana hiki ke kumu i nā wrinkles ma ka ʻili o ka uhi. Eia kekahi, ʻo ka haki ʻana o ke kiʻi hoʻoheheʻe i ka wā e haʻalele ai ka mea polyethylene i ka puka i ka wā o ke kaʻina extrusion e hana pū kekahi i nā hemahema maikaʻi e like me nā wrinkles. ʻO nā ʻano hana hoʻomalu e pili ana i nā kumu o nā wrinkles e pili ana i ka hoʻoponopono ʻana i ka paʻakikī a me ke kaomi ʻana o ka wili pahu a me ka ʻili kaomi. Mai kēia hiʻohiʻona, e hoʻonui kūpono i ka nui extrusion o ka polyethylene e hoʻomalu i ka haki ʻana o ke kiʻiʻoniʻoni.
