Te whakarewa i te kani:Ka hangaia te paipa mā te whakamahi i te tukanga whakarewa pewa ruku (SAW), arā, ko te hanganga o tētahi hononga whakarewa mā te whakamahi i tētahi tukanga whakarewa pewa ruku tonu. E mōhiotia ana tēnei tikanga mō te whakaputa i ngā whakarewa kounga teitei, ōrite.
Whakamutunga Pania Pango:Mā te paninga pango ka ātete ki te waikura, ka whakarei ake hoki i te āhua ataahua o te paipa rino. Ka āwhina hoki te peita ki te tiaki i te paipa i te wā e rongoa ana, e kawe ana hoki.
Ngā tono:Ko te Paipa Rino API 5L ASTM A53 Grade B, he mea whakakikorua ki te SAW, he mea peita pango, e whakamahia whānuitia ana i roto i ngā momo mahi, tae atu ki ngā paipa tuku hinu me te hau, te tautoko hanganga i roto i te hanganga, me ētahi atu mahi ahumahi me te miihini.
