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 whakapumautanga, me te paipa rino e kore e turuturu. Ko te Whakamatau Hydraulic ranei ka taea te whakakapi e te Eddy o naianei Whakamātautau, te Whakamātautau Rerewhanga Rerewharewha ranei.
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 o te Roopu Ka Whakapumautia I roto i Te Kiriata, Ka Taea Te Apiti Atu Whakamatau Whakamate Kore.
Whakamātautau Whakapapa:
Ko nga ngongo he nui ake i te 22 mm te roa 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 te Paipa o nga Koeke P91, P92, P122, me te P911, Brinell, Vickers, Rockwell ranei ka mahia nga whakamatautau pakeke ki runga i tetahi tauira mai ia rota.
