Waea noke
Whakaahuatanga:
Ka hangaia e te 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 o te rewharewha, te paera poipoi, te paera 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 ki te 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.
