Nā Paipu me nā uhi no ka anti-corrossion
Nā Huahana
Nā Kūlana: Hoʻonohonoho ʻia nā kūlana no nā paipu i hoʻopaʻa ʻia anti-corrosion e nā hui e like me ka American Society for Testing and Materials (ASTM), ka International Organization for Standardization (ISO) a me ka National Society of Corrosion Engineers (NACE). Hōʻike kēia mau maʻamau i nā koi no nā mea uhi, nā ala noi, nā kaʻina hana hoʻokolohua a me nā kūlana hana.
Hoʻokaʻawale ʻia ma muli o ka mālama ʻana i ka ʻili: Hiki ke hoʻokaʻawale ʻia nā paipu me nā pale anti-corrosion ma muli o ke ʻano o ka uhi i hoʻohana ʻia. ʻO nā ʻāpana maʻamau ka: Fused Bonded Epoxy (FBE) Coating Polyethylene (PE) a i ʻole polypropylene (PP) ka uhi ʻana i ka asphalt a i ʻole ka asphalt ka pena Zinc waiwai nui Polyurethane coating Coal tar enamel coating.
Nā noi: Hoʻohana nui ʻia nā paipu me nā ʻāpana anti-corrosion i nā ʻoihana like ʻole, e like me: ʻAila a me Gas: ʻO nā paipu i hoʻohana ʻia no ka lawe ʻana i ka ʻaila maʻemaʻe, ke kinoea maoli a me nā huahana ʻaila Ka wai a me ka wai ʻino: no ka wai lepo a me ka hoʻoheheʻe ʻana. a me waho o ke kai: no nā paipu o lalo o ka moana a me nā hale o waho o ke kai: No ka hoʻohana ʻana ma nā alahaka, nā pā a me nā hale ʻē aʻe i ʻike ʻia i nā kūlana kaiapuni koʻikoʻi He mea koʻikoʻi kēia mau paipu no ka mālama ʻana i ka pono a me ka lōʻihi o nā ʻōnaehana koʻikoʻi a me nā ʻōnaehana ʻoihana, ʻoi aku ma nā wahi ʻino a ʻino paha. I ka wehewehe ʻana a i ʻole ke koho ʻana i ka paipu me kahi pale anti-corrosion, he mea nui e nānā i nā kūlana kūpono a kūkākūkā me nā poʻe loea o ka ʻoihana e hōʻoia i ka hoʻokō ʻana o ka uhi i koho ʻia i nā koi kikoʻī o ka noi i manaʻo ʻia.
