(Tuhipoka: He korero whakarāpopoto tenei mai i te ASME Specification A53. Tena tirohia te Paerewa motuhake, Whakatakotoranga ranei, whakapā mai ranei mo etahi atu korero.)
ASTM A53 paipa maitai tuitui he tohu paerewa Amerika. Ko te A53-F e rite ana ki nga taonga Q235 o Haina, A53-A e rite ana ki nga taonga nama 10 a Haina, me te A53-B ki nga taonga 20 o Haina.
Te tukanga whakaputa
Kua wehea te tukanga whakangao putorino maitai ki te wera-hurihia me te makariri putorino.
1. Te tukanga whakaputa o te putorino maitai kore-wera: pire ngongo → whakawera → perforation → toru-roera /whakawhitiwhiti & huri haere tonu → de-pipe → rahinga → whakamahana → whakatika → whakamātautau waipēhi → tohu → putorino maitai tuitui me te huanga huanga kua kitea.
2. Te tukanga whakaputa o nga ngongo rino korekore: ngongo parakore → whakawera → perforation → pane → annealing → pickling → hinu → tuhi matao maha → ngongo parakore → maimoatanga wera → whakatika → whakamātautau waipēhi → tohu → rokiroki.
Nga tono
1. Hanga: te paipa i raro, te wai o raro, me te kawe wai wera.
2. Te tukatuka miihini, te kawe ringaringa, nga waahanga miihini tukatuka, aha atu.
3. Te Hiko: Te tuku hau, te paipa wai hiko hiko
4. Nga ngongo anti-pateko mo nga tipu hiko hau, etc.
