Pehea e hoʻokaʻawale ai i nā paipu kila huki anu

1. Ma mua o ka hemo ʻana o ka ʻōpalapaipu kila huki anu, pono e wehe mua ʻia nā lepo ʻike ʻia ma luna o ka ʻili, a laila e hoʻohana ʻia ka solvent a i ʻole ka mea hoʻomaʻemaʻe e wehe i ka ʻaila.

2. E hoʻohana i ka tungsten steel shovel e wehe i nā wahi nui o ka ʻōpala.

3. E hoʻohana i ka ʻōpala a me ka pulupulu uea e wehe i ka ʻōpala mai nā ʻaoʻao a me nā kihi o ka paipu kila.

4. E hoʻohana i kahi faila e wehe i nā protrusions e like me ka welding slag a me nā burrs like ʻole mai nā paipu kila.

5. E hoʻomaʻemaʻe ʻia nā paipu kila i huki ʻia me ke kapa one a me ka pulupulu uea kila.

(1) Paipu kila ka pollution kalapona: nā ʻōpala i hoʻopili ʻia me nā ʻāpana kila kalapona i hana ʻia i ke pākaukau Primary me ke ʻano corrosion, ka hopena i ka ʻino electrochemical.

(2) ʻO ka ʻoki ʻana i ka paipu kila huki anu: ʻo ka hoʻopili ʻana i nā mea ʻeleʻele e like me ka ʻoki ʻana i ka slag a me ka spatter a me ka hoʻokumu ʻana o ka pākaukau Primary me ka mea corrosive e hoʻopōʻino electrochemical.

(3) Hoʻoponopono Baking: hoʻololi like ʻole ka haku mele ʻana a me ke ʻano metala o ka wahi hoʻomehana ahi, e hoʻokumu ana i ka pākaukau Primary me ke ʻano corrosion, e hopena i ka ʻino electrochemical.

(4) Steel paipu kuʻihao: nā kino defects (undercut, pore, māwae, incomplete fusion, incomplete penetration, etc.) a me kemika defects (coarse grain, poor chromium at grain boundary, segregation, etc.) in the welding area form Primary pākaukau me ka mea ʻino e hana i ka ʻino electrochemical.

(5) Material: nā kino kemika (ʻano like ʻole, S, P nā haumia, a me nā mea ʻē aʻe) a me nā hemahema kino o ke kino (looseness, nā lua one, nā māwae, a me nā mea ʻē aʻe) o ka paipu kila e kūpono i ka hoʻokumu ʻana i ka pākaukau Primary me ka corrosion medium a me ka hana ʻana. ʻinoʻino electrochemical.

(6) Passivation: Poor acid pickling passivation hopena i uneven a lahilahi passivation film ma ka ili o anu anu huki kila paipu, i mea prone i electrochemical corrosion.

I ka hōʻuluʻulu ʻana, he hōʻuluʻulu kēia o ka ʻike pili e pili ana i ka decontamination a me ka mālama kemika o nā paipu kila huki anu.Ke manaʻoʻiʻo nei au ua loaʻa i kēlā me kēia kanaka ke aʻo hou a me ka hoʻomaopopo.Inā makemake ʻoe e aʻo hou aku i ka ʻike, e ʻoluʻolu e hoʻomau i ka hahai ʻana iā mākou.
