Nā mea e pono ai ka nānā ʻana i ka wā e wili ai i ka paipu keleawe

Nā kikoʻī hou aku loulou:https://www.wanmetal.com/

ʻO ka paipu keleawe: he ʻano paipu metala non-ferrous, ʻo ia ka paipu ʻole i kaomi ʻia a huki ʻia. ʻO nā paipu keleawe he ikaika a pale i ka corrosion, a ua lilo lākou i mea hoʻokomo i nā paipu wai paipu, nā paipu hoʻomehana a me nā mea hoʻoluʻu ma nā hale kūʻai a pau o ka hale e ka poʻe ʻaelike hou. ʻO nā paipu keleawe ʻoi aku ka maikaʻi o ka hoʻolako wai.

Nā hiʻohiʻona o ka paipu keleawe:

ʻOi aku ka māmā o ka paipu keleawe i ke kaumaha, maikaʻi ka conductivity thermal a me ka ikaika kiʻekiʻe ma ka wela haʻahaʻa. Hoʻohana pinepine ʻia i ka hana ʻana i nā mea hoʻololi wela (e like me condensers, etc.). Hoʻohana ʻia ia e hōʻuluʻulu i nā pipeline cryogenic i nā lako hana oxygen. Hoʻohana pinepine ʻia nā paipu keleawe me nā anawaena liʻiliʻi no ka lawe ʻana i nā wai i kaomi ʻia (e like me nā ʻōnaehana lubrication, nā ʻōnaehana ʻaila, a me nā mea ʻē aʻe) a me nā paipu ana kaomi no nā mea kani. He ikaika ka paipu keleawe a pale i ka corrosion.

ʻO ka nui o nā mea maikaʻi aʻe: ʻo ka paipu keleawe he paʻakikī i ke ʻano, ʻaʻole maʻalahi ke corrode, a kūpaʻa i ka wela kiʻekiʻe a me ke kaomi kiʻekiʻe, a hiki ke hoʻohana ʻia i nā ʻano kaiapuni keleawe-noa. Ke hoʻohālikelike ʻia me nā paipu keleawe, ʻike ʻia nā hemahema o nā paipu ʻē aʻe. ʻO kahi laʻana, ʻo nā paipu kila galvanized i hoʻohana ʻia i nā hale noho i ka wā ma mua he maʻalahi loa ka pala. Inā ʻaʻole hoʻohana ʻia no ka manawa lōʻihi, e melemele ka wai paipu a liʻiliʻi ke kahe o ka wai. Aia kekahi mau mea e emi koke ana ka ikaika ma nā wela kiʻekiʻe, hiki ke hoʻopilikia i ka palekana ke hoʻohana ʻia i nā paipu wai wela. Eia naʻe, no ka mea, ʻoi aku ka kiʻekiʻe o ka helu heheʻe o ke keleawe ma 1083 degere, ʻoi aku ka liʻiliʻi o ka mana o ka wela o ka ʻōnaehana wai wela ma luna o ka paipu keleawe. ʻO nā paipu keleawe maʻamau, ʻo ia nā paipu keleawe no nā mea hana, nā paipu keleawe no ka pahu hau, nā paipu keleawe kiʻekiʻe, nā paipu keleawe kūpaʻa ʻole, nā paipu keleawe no ka hoʻopili ʻana, nā paipu keleawe no nā ala wai, nā paipu keleawe no ka hoʻomehana uila, a me ka melemele no ka hana ʻoihana. ʻO nā paipu keleawe a pēlā aku.

ʻO ka mālama ʻana i ka wiliwili keleawe:

1. I ka wā o ke kaʻina hana kuʻi, e mālama mau i ka lapalapa e uhi ana i nā pilina e pale aku i ke komo ʻana o ka ea;

2, e hoʻomaloʻo ʻia ka flux, e hoʻoheheʻe ʻia ka wai ma 100 ℃, a e lilo ke kahe i keʻokeʻo milky;

3, e hoʻohūhū ka flux ma 316 ℃;

4, lilo ka flux i paʻi ma 427 ℃;

5. Lilo ka flux i ka wai ma 593 ℃, kahi kokoke i ka mahana wela;

6. ʻO ka solder i loaʻa ka 35% -40% kālā heʻe ma 604 ℃ a kahe i 618 ℃;

7. E hoʻomaopopo i nā mea hana ʻelua e hoʻopili ʻia e pono e hoʻomehana ʻia me kahi lama wili;

8. Ma o ke kala lapalapa, hiki iā ʻoe ke nānā inā kūpono ka mahana. Ke piʻi ka mahana i ka mahana wela, e ʻike ʻia ka ʻōmaʻomaʻo o ka lapalapa, a i ka wā e hiki ai ka mahana i ka mahana kuʻi kālā, ʻo ka lapalapa ʻōmaʻomaʻo ke kūpono ka mahana;

9. Hoʻopiliʻia ka paipu keleawe a me ka paipu kila i kekahi i kekahi, aʻo ka paipu keleawe e hoʻomehana muaʻia (no ka mea, ua wikiwiki ka hoʻoili wela o ka paipu keleawe, pono ka wela);

10. I ka wā o ka brazing kaʻina hana, ʻaʻole pono e pani ʻia ka lama kuʻihao i hoʻokahi manawa i nā manawa a pau, hiki ke hoʻoneʻe ʻia i kahi kiʻi o ʻewalu;

11. Manaʻo ʻia e hoʻohana i ka lama kuʻihao nui, i hiki ke hoʻohana ʻia kahi lapalapa palupalu e loaʻa ai ka wela nui me ka ʻole o ka overpressure a i ʻole ka "puhi", a aia kahi plume liʻiliʻi ma ka lapalapa cone i loko.
