Whakaritenga Whakamatau
Whakamātautau Hydraustatic:
Me Whakamatauhia te Paipa Hiko Tira Kotahi Ma te Kotahi. He 20 MPa te Pehenga Whakamatau Morahi. I raro i te Pehenga Whakamatau, Kaua e iti iho i te 10 S te wa whakapumau, me te paipa rino kia kore e turuturu.
Whai muri i te whakaae a te Kaiwhakamahi, ka taea te whakakapi i te whakamatautau Hydraulic e te whakamatautau o naianei a Eddy o naianei, ki te whakamatautau ranei i te rerenga rerenga aukume.
Whakamātautau kore kino:
Ko nga paipa e hiahia ana kia nui ake te tirotiro me tirotirohia e te Ultrasonically takitahi. I muri i te Whakawhitiwhitinga Me Te Whakaaetanga a te Roopu Ka Whakatakotoria I Te Kiriata, Ka Taea Te Apiti Atu I etahi atu Whakamatau Whakamate-kore.
Whakamātautau Whakapapa:
Ko nga ngongo me te diameter o waho ka nui ake i te 22 mm ka tukuna ki te whakamatautau papatahi. Karekau he whakamomori, he wahi ma, he poke ranei i te wa o te whakamatautauranga katoa.
Whakamātautau pakeke:
Mo nga paipa o nga Tohu P91, P92, P122, me P911, me mahi nga whakamatautau pakeke a Brinell, Vickers, Rockwell ranei ki runga i tetahi tauira mai ia rota.
Whakamātautau Piko:
Mo te paipa kua neke ake te diameter ki te NPS 25 me te 7.0 iti iho ranei te diameter ki te matotoru o te pakitara, ka tukuna ki te whakamatautau piko hei utu mo te whakamatautau papatahi. Ko etahi atu paipa e rite ana, neke atu ranei te diameter o te NPS 10 ka tukuna he whakamatautau piko hei whakakapi i te whakamatautau papatahi i raro i te whakaaetanga a te kaihoko.
