— He Aratohu Whānui ki te Paerewa me ngā Rauemi o ngā Paipa Tuitui Matao-Hanga o Rūhia
Paipa Sanon – Tō Kaiwhakarato Pono mō ngā Ngongo Rino Tika e Tutuki ana ki te GOST
1. Tirohanga Whānui mō te Pūnaha Paerewa: Te Hononga Tāpiri i waenganui i te GOST 8734 me te GOST 8733
Ko te GOST 8734-75 te paerewa ā-ahu/ā-whakakotahi mō ngā paipa maitai kore-whakairo matao (toia matao/hurihuri matao) i Rūhia (ko te USSR o mua). E tohu ana i te whānuitanga o te diameter o waho, te raupapa matotoru pakitara, ngā ātete ā-ahu, ngā momo roa me ngā rerekētanga e whakaaetia ana, me te taumaha ariā o ngā paipa. He nui ake te tika o ngā ā-ahu o te tukanga toia matao i ngā paipa huri wera, ā, he mea pai mō ngā taputapu tika, ngā pūnaha waipēhi, ngā hanganga miihini tino tika, me ngā tono rite.
I roto i te pūnaha paerewa o Rūhia, me whakamahi tahi te GOST 8734-75 me tōna paerewa āhuatanga hangarau hoa GOST 8733-87. Ko te tikanga, e whakamārama ana te GOST 8734-75 i "te āhua o te paipa" (ngā ine me ngā manawanui), ko te GOST 8733-87 ia e whakamārama ana i "te rauemi me tōna kaha" (te hanganga me te mahi).
| Paerewa | Taitara Hainamana | Whānuitanga |
|---|---|---|
| GOST 8733-87 | Ngā paipa maitai kore-whakairo matao – Ngā tikanga hangarau | Ngā tohu maitai, te hanganga matū, ngā āhuatanga miihini, ngā whakamātautau tukanga, ngā whakamātautau waipūmau, ngā ture tirotiro, te tohu, te takai |
