Ngā Tikanga Hononga Rerekē mō ngā Paipa Ukume Ātete-Kakahu

1: Hononga whakarewa

 Ko te hononga whakarewa he tikanga honohono e whakamahia whānuitia ana i roto i ngā paipa uku ātete-kakahu. Ko ngā mahi motuhake koia ēnei:

 1). Te whakarewa i te mokowā: Tuatahi, whakarewahia ngā mokowā ki te pakitara o roto o te paipa. Ka whakamahia ēnei mokowā hei whakapiri i ngā pepa uku, i ngā arai rānei e ātete ana ki te pakaru. Ka whakamahia te hangarau mono-whakauru huna hei whakarewa i ngā mokowā hei whakarite i te pumau me te ataahua o te hononga.

 2). Te tāutanga o te pepa uku: Kātahi ka tāutahia te pepa uku ātete-mau, te arai rānei, he āhua-pewa, he kōhao kei roto i ngā kōhao. Hei whakarite i te kounga o te hononga, ka whakamahia he here ngāwari mimiti (pērā i te here uku, me kaha ki te tu atu i te pāmahana ≥350°C) i waenganui i te uku me te pakitara o roto hei whakakī, ka taea te mimiti i ngā ngaru wiri, ā, ka mahi i te mahi hononga tuarua.

 3). Te pakari o te whakarewa: I te whakarewa i ngā mokowā ki te paipa, me aro nui ki te pakari o te whakarewa. Hei tauira, i te whakarewa me ngā wāhanga whakarewa, ko te maha o ngā pūwāhi whakarewa i roto i te 100mm he nui ake i te 4 ngā pūwāhi, ā, he maha ngā wā ka whakamahia te whakarewa pewa argon hei whakarite i te pakari o te whakarewa me te whakaiti i te wetewete me te taka atu i puta mai i te wiri miihini me ētahi atu take.

 Ko te painga o te hononga whakarewa he pakari te hononga, ka taea te tu atu i te pēhanga me te pānga nui, ā, he pai hoki mō ngā āhuatanga mahi uaua maha.

2. Hononga flange

Haunga te hononga whakarewa, ka taea hoki te hono me te tāuta i ngā paipa uku ātete-kakahu mā roto i ngā flange. Me mārama ēnei take i te wā e tāuta ana i te hononga flange:

 1). Kia tūpato te pupuri: Me tūpato te pupuri i ngā paipa uku ātete-pakaru i te wā e kawe ana, e tāuta ana hoki, kia kore ai e pāngia e ngā tukinga kino, e ngā mea pakeke hoki e pā ki te mata o te uku, kia kore ai e kino te mata o te pito.

2). Te hononga tika: I te wā e tāuta ana i ngā paipa uku, me whakarite te rārangi pokapū o te paipa ki te rārangi pokapū o te paipa hei hono atu kia tika ai te hononga o ngā pito e rua, kia tika ai hoki te whakahaere i te korenga o te hononga o te mata pito i roto i tētahi whānuitanga (pērā i roto i te 1 mm).

3). Te tāutanga ahunga: Mā te tikanga whakapiri uku ā-roto me te tikanga whakapiri o te ngongo uku ātete-kakahu ka whakatau i tōna ahunga tino pakari. I te wā tāutanga, me rite te ahunga o te wai kawe me te āputa hononga kia rite ki ngā whakaritenga hangarau hei whakaiti i te horoi me te kakahu o te paipa.

4). Tirohia te hiri: Mō ngā paipa uku ātete-pakaru e kawe ana i ngā wai pērā i te paura, te hau me ngā wai, me tino tirohia te hiri o te hononga i te wā e tāuta ana hei ārai i te turuturu o te wai.

3. Ētahi atu tikanga hononga

 Haunga ngā tikanga hononga matua e rua o runga ake nei, kei reira anō ētahi atu tikanga hononga mō ngā paipa uku ātete-kakahu, pērā i:

 Hononga papaki: Whakamahia ngā rau uku, ngā arai uku rānei hei whakapiri tika ki roto i te paipa. He uaua ake te hanga i tēnei tikanga hononga, me whai hangarau hanga ngaio, ā, he nui ake ngā whakaritenga mō ngā piripiri.

Hononga ranu: I ētahi wā motuhake, ka whakamahia pea he tikanga hononga ranu e whakakotahi ana i te whakarewa me te whakapiri hei whakatutuki i ngā whakaritenga whakamahinga motuhake.

 I te nuinga o te wā, he maha ngā huarahi hei hono i ngā paipa uku ātete-kakahu, ā, me whakatau te tikanga motuhake hei whiriwhiri i runga i te whakamahinga me te taiao mahi. I te wā o te hononga, me tino whai i ngā tikanga whakahaere me ngā whakaritenga hangarau e tika ana kia mau ai te kounga me te roa o te ratonga o te hononga.
