Ko nga ahuatanga o te riipene aa-a-te-a-Amerika
1. Ko nga hua kua hangaia, kua hangaia kia rite ki nga paerewa ASME B16.34 me BS, me te hanganga whaitake, te hiri pono, te mahi pai me te ahua ataahua;
2. Ko te mata hiri kua whakakikoruatia ki te carbide cimented Co e hangai ana he pai te kakahu, te waikura, te abrasion me te roa o te mahi;
3. Ko te kakau takirere he pai te aukati waikura me te rakuraku i muri i te tinei me te whakamahana me te maimoatanga nitriding mata;
4. Ko te kohao me te pehanga ≥ class1500 e tango ana i te hanganga hiri whakakaha whaiaro, a ka piki ake te mahi hiri me te piki o te pehanga o roto, e whakarite ana i te pono o te hiri;
5. Ko te paera he mea whakamuri te hanganga hiri, he pono;
6. Ko nga mea o nga waahanga me te rahi o te pito o te reke whakahiato o te flange ka taea te whiriwhiri tika i runga i nga ahuatanga mahi me nga whakaritenga a te kaiwhakamahi ki te whakatutuki i nga momo hiahia miihini.
