ʻO nā paipu wiliwili wiliwili (SSAW) no nā papahana mālama wai, ʻo ia nā paipu kila wiliwili ʻia me nā anawaena nui, no ka mea, he nui ka wai e kahe ana i kēlā me kēia manawa, hiki ke hoʻomaikaʻi maikaʻi i ka hana. No ka mea e holoi mau ʻia ka paia o loko o ka paipu kila e ka wai, ʻaʻole mālama ʻia ka paia o loko me ka anti-corrosion treatment, akā ʻo ka waho ma ke ʻano o ke poʻo, no laila pono e hana ʻia ka anti-corrosion e hana ai. ʻO ka ua a me ka ʻike ʻana i ka lā, no laila ʻoi aku ka kiʻekiʻe o nā koi no nā pale anti-corrosion.

Ma mua o ka anticorrosion o nā paipu kila spiral no nā papahana mālama wai, pono e hoʻoneʻe ʻia ka ʻili o nā paipu kila, a ʻo ka papa e hiki i st2.5. Ma hope o ka sandblasting, e hoʻopili koke i ka anti-corrosion primer. ʻO ka anti-corrosion primer ka mea maʻamau epoxy zinc-waiwai peʻa me ka zinc content o 70% a ʻoi aku paha, ʻo ka waena ka pena epoxy mica, a ʻo ka papa o waho he anti-oxidation a me ka corrosion. Pena polyurethane.

Ma mua o ka haʻalele ʻana i ka hale hana, pono e hoʻāʻo ʻia ka paipu kila spiral no nā waiwai mechanical, flattening a flaring, a pono e hoʻokō i nā koi o ka maʻamau. ʻOi aku ka maʻalahi o nā paipu kila wiliwili i ke anawaena a me nā kikoʻī mānoanoa o ka paia, ʻoi aku ka maikaʻi ma ka hana ʻana i nā paipu mānoanoa kiʻekiʻe, ʻoi aku ka liʻiliʻi a me ke anawaena o nā paipu mānoanoa. Nui nā koi e pili ana i nā kikoʻī o ka paipu kila spiral. Pono e ho'omalu pono 'ia ke anawaena a me ka nui o ka paipu kila.

Pono ka hoʻokō ʻana i ka ʻenehana anti-corrosion i kēia mau kūlana ma mua o ka hiki ke hoʻokō:

ʻO ka mea mua, ua paʻa ka hoʻolālā a me nā palapala ʻenehana ʻē aʻe, a pono e loiloi pū ʻia nā kiʻi kūkulu. ʻO ka lua, ua hoʻopau ʻia ka hōʻike ʻenehana o ka hoʻolālā kūkulu, a ua hoʻokō ʻia ke aʻo ʻana i ka ʻenehana palekana a me ka hoʻomaʻamaʻa ʻenehana pono. ʻO ke kolu, pono e loaʻa i nā mea hana a pau, nā paipu a me nā mea hoʻopili i kahi palapala hale hana, a i ʻole kahi palapala moʻokāki pili. ʻO ka hā, ʻo nā mea hana, nā mīkini, nā lako hana a me nā kahua. ʻO ka lima, pono e loaʻa nā lako pale pono i palekana a hilinaʻi, a ʻo ka wai hana, ka uila, a me ke kinoea e hiki ke hoʻokō i nā pono hana mau.
