Waea noke
Whakaahuatanga:
Ka whakaputahia e TWS nga raupapa pukapuka-a-ringa teitei o te miihini taputapu kutukutu, kei runga i te anga CAD 3D o te hoahoa modular, ka taea e te tauwehenga tere te whakatau i te taipana whakauru o nga paerewa rereke katoa, penei i te AWWA C504 API 6D, API 600 me etahi atu.
Ko o maatau miihini taputapu kutukutu, kua whakamahia nuitia mo te rewharewha rewharewha, te paera poipoi, te raima mono me etahi atu reera, mo te mahi whakatuwhera me te kati. Ko nga waahanga whakaheke tere BS me BDS e whakamahia ana i roto i nga tono whatunga paipa. Ka taea e te hononga ki nga paera te whakatutuki i te paerewa ISO 5211 me te whakarite.
Āhuatanga:
Whakamahia nga tohu tohu rongonui hei whakapai ake i te pai me te oranga ratonga. Ko te kutukutu me te rakau whakauru kua whakaritea me nga raka e 4 mo te haumaru ake.
Ka hiritia te Worm Gear ki te O-mowhiti, ka hiritia te kohao o te kakau ki te pereti hiri rapa hei whakamarumaru i te wai huri noa me te whakamarumaru puehu.
Ko te waahanga whakaheke tuarua e kaha ana ki te tango i te maitai waro kaha me te tikanga maimoatanga wera. Ko te ōwehenga tere whaitake e whakarato ana i te wheako mahi mama ake.
He mea hanga te noke ki te rino ngongo QT500-7 me te rakau kutukutu （waohanga maitai waro, 304 ranei i muri i te tinei）， ka honoa ki te tukatuka tino-tika, kei a ia nga ahuatanga o te aukati kakahu me te pai o te tuku.
Ka whakamahia te pereti tohu tohu tuunga konumohe whakarewa-mate hei tohu i te tuunga whakatuwheratanga o te takirere.
Ko te tinana o te taputapu noke he mea hanga ki te rino ductile kaha teitei, a ka tiakina tona mata e te rehu epoxy. Ko te whana hono hono he rite ki te paerewa IS05211, he maamaa ake te rahi.
