Te Whakamātau i ngā Tukanga Whakarewa Paipa: He Aratohu Whānui

Whakaahuatanga Poto:

He mea nui ngā tukanga whakarewa paipa i roto i ngā momo ahumahi tae atu ki te hanga, te whakangao, te hinu me te hau, me ētahi atu. He mea nui te mōhio ki ēnei tikanga hei whakarite i te hanganga me te haumaru o ngā paipa. I roto i tēnei aratohu whānui, ka whakamāramahia e mātou'Ka rukuhia ngā āhuatanga matua o te tukanga whakarewa paipa, tae atu ki ngā tikanga, ngā taputapu me ngā mahi pai rawa atu.

1. Kia mārama ki ngā kaupapa matua o ngā tikanga whakarewa paipa

Ko te whakarewa paipa he hononga i ngā wāhanga o ngā paipa hei hanga i tētahi paipa tonu, ā, kāore e turuturu. Me mārama pai ki ngā tikanga whakarewa pēnei i te TIG (hau korekore tungsten), te MIG (hau korekore whakarewa) me te whakarewa rakau mō tēnei mahi. He painga me he herenga tō ia hangarau, ā, ko te whiriwhiri i te hangarau ka whakawhirinaki ki ngā āhuatanga pēnei i te momo rauemi, te whānui o te paipa me te wāhi whakarewa.

2. Te whakarite i te whakarewa paipa

He mea nui te whakarite tika i mua i te tīmatanga o te tukanga whakarewa. Kei roto i tēnei ko te horoi i ngā mata hei whakarewa, te whakarite kia tika te tāutanga o ngā paipa, me te whiriwhiri i ngā rauemi whakarewa e tika ana. Hei tāpiri, he mea nui kia whai i ngā tikanga haumaru, kia kore ai he tūponotanga mōrearea i te wāhi mahi.

3. Kōwhiria ngā taputapu tika

He mea nui te whiriwhiri i ngā taputapu whakarewa hei angitu i tō kaupapa whakarewa paipa. Kei roto i tēnei ko te whiriwhiri i te mīhini whakarewa e tika ana, ngā hiko whakarewa, ngā hau ārai me ētahi atu taputapu tāpiri. He mea nui kia haumi ki ngā taputapu kounga teitei hei whakarite i te pono o ngā whakarewa me te pūnaha paipa katoa.

4. Whakatinanahia ngā tikanga pai rawa atu

He mea nui te piri ki ngā tikanga pai rawa atu kia tutuki ai he whakarewa paipa kounga teitei, he pakari hoki. Kei roto i tēnei ko te pupuri i ngā tawhā whakarewa tika pēnei i te ngaohiko, te iahiko me te tere haere kia tika ai te urunga me te hanumi. Hei tāpiri, he mea nui te whakarite hononga tika, tae atu ki te whakarite i te piko me te taha, kia tutuki ai he whakarewa kaha me te pono.

5. Whakarite kia tutuki ngā whakaritenga ture

I roto i te maha o ngā ahumahi,ngā tukanga whakarewa paipame piri ki ngā ture me ngā paerewa motuhake hei whakarite i te pono me te haumaru o te pūnaha paipa. Kei roto pea i tēnei ko te tutuki i ngā whakaritenga pēnei i te ASME B31.3, API 1104, AWS D1.1 rānei. Me mārama pai ngā kaiwhakarewa me ngā kaitirotiro whakarewa ki ēnei whakaritenga, ā, me whakarite kia tutuki ngā tikanga whakarewa katoa i ngā paerewa e hiahiatia ana.

6. Te whakahaere kounga me te tirotiro

He wāhanga nui o te kaupapa whakarewa paipa te whakahaere kounga me te tirotiro. Kei roto i tēnei ko te tirotiro tirohanga, te whakamātautau kore-whakangaro (NDT) me te whakamātautau whakangaro hei whakarite i te kounga me te pono o ngā whakarewa. He mahi nui tā ngā kaitirotiro whakarewa ki te manatoko kei te tutuki ngā tukanga whakarewa i ngā whakaritenga me ngā paerewa kua tohua.

Hei whakarāpopototanga, ko te matatau ki ngā tikanga whakarewa paipa me whai i te huinga o te tohungatanga hangarau, ngā taputapu tika, te piri ki ngā mahi pai rawa atu, me te tutuki i ngā paerewa ahumahi. Mā te whai i ēnei aratohu, ka taea e ngā kaiwhakarewa te whakarite i te pono me te haumaru o ngā pūnaha paipa i roto i ngā momo mahi ahumahi. He mea nui hoki te whakangungu tonu me te mōhio ki ngā whanaketanga hou o te hangarau whakarewa hei matatau ki ngā tikanga whakarewa paipa me te whakatutuki i te hiranga i roto i te mara.
