Ko te hononga paipa wiri he wāhanga o te paipa wiri, kua wehea ki ngā hononga tāne me ngā hononga wahine, e honoa ana i ngā pito e rua o te tinana o te paipa wiri. Kei te hononga he miro tīwiri (miro tīwiri matotoru) hei hono i ia paipa wiri. I roto i te tukanga wiri, ka wetewetehia te hononga, ā, ka pāngia te mata o te hononga e te kaha ngau nui, nō reira he nui ake te matotoru o te pakitara o te hononga paipa wiri, he nui ake te diameter o waho o te hononga i te diameter o waho o te tinana paipa, ā, ka whakamahia te maitai koranu he kaha ake. Ko ngā hononga paipa wiri ā-whare he mea hanga i te maitai koranu 35CrMo.
Me tutuki ngā whakaritenga e toru mō te hononga o te miro tīwiri, arā, kia ōrite te rahi, kia ōrite te momo miro tīwiri, ā, kia ōrite te miro tīwiri tāne me te wahine. He rerekē ngā rahi hononga o ngā paipa wiri rerekē. He rerekē anō hoki te momo miro o te paipa wiri o te rahi kotahi. He uaua hoki te tino ōrite te momo hononga e whakamahia ana e ia kaihanga paipa wiri. Nō reira, hei whakahaere i te wehewehe i waenga i ngā hononga paipa wiri me ngā tono hangarau, kua whakaritea e API he whakaritenga ōrite mō te momo hononga paipa wiri, hei hanga i ngā hononga paipa wiri API e whakamahia whānuitia ana i roto i te umanga hinu.
Kei te wātea ngā hononga paipa API i roto i ngā paerewa tawhito me ngā paerewa hou. Ko te hononga paipa keri API tawhito e whakaarohia ana mō te whakamahinga wawe o ngā paipa keri pai, e wehea ana kia toru ngā momo: papatahi ā-roto (IF), pokaia (FH) me te noa (REG).
Ko te hononga papatahi o roto e whakamahia ana mō te whakamātotoru o waho o te paipa keri, e tohuhia ana e te diameter o roto o te paipa keri me te diameter o roto o te hononga i te whakamātotoru o te tinana paipa, ā, he iti te ātete rere o te wai keri, he pai ki te whakapai ake i te mana wai o te mata keri, engari he nui te diameter o waho o te hononga, ā, he ngāwari ki te mau.
He pai te hononga poka mō te whakamātotoru ā-roto o te paipa keri, e tohuhia ana e ngā diameter ā-roto e rua o te paipa keri, ā, ko te diameter ā-roto o te hononga he ōrite ki te diameter ā-roto o te whakamātotorutanga o te tinana paipa, engari he iti iho i te diameter ā-roto o te wāhanga tinana paipa. He nui ake te ātete o te wai keri e rere ana i roto i te hononga i te hononga papatahi o roto, engari he iti ake tōna diameter o waho i te hononga papatahi o roto.
He pai te hononga noa mō te whakamātotoru ā-roto o te paipa keri. He iti noa te whānui o roto o tēnei hononga, he iti iho i te whānui o roto o te paipa keri. Nō reira, e toru ngā whānui poka rerekē o te paipa keri e hono ana ki ngā hononga noa. Ka rere te wai keri mā roto i tēnei hononga me te ātete nui rawa atu, engari ko tōna whānui waho he iti rawa, ā, he kaha ake. He maha ngā wā ka whakamahia ngā hononga noa mō ngā paipa keri iti te whānui me ngā paipa keri whakamuri, tae atu ki ngā keri, ngā taputapu hī ika, me ētahi atu. Ko ngā momo hononga e toru e whakamahi ana i ngā miro āhua "V", engari he rerekē rawa te momo miro tīwiri (e whakaatuhia ana e te whānui o te tapahi o runga), te tawhiti o te miro tīwiri, te whakawhāiti me te rahi.
Te tautuhi hononga
1. kōhao FH, XH, kāore i te kitea noa i te toa taputapu, kāore i te whakamahia whānuitia.
2. Ko te IF me te REG noa e whakamahia whānuitia ana, ko te rerekētanga penei:
Mēnā e 4 ngā pātene mō ia inihi, he matotoru ake te miro tīwiri, ā, he iti ake te whakawhāiti, REG 5 ngā pātene mō ia inihi, he iti ake te miro tīwiri, ā, he nui ake te whakawhāiti. Ko te rahi o te miro tīwiri IF kei waenga i te 2-3/8 "ki te 4-1/2", ā, ko ngā mea nui ake i te 4-1/2 "kāore he IF, ko te tikanga he REG, ā, ko ngā mea 7-5/8" me runga ake kāore he REG.
3. Tikanga whakapuakitanga noa:
E toru ngā tau e tohuhia ana, pērā i te 310,410,411, me ētahi atu.
Ko te tau tuatahi e tohu ana i te rahi (2 ~ 7) e kitea whānuitia ana: 2-2 -, 3-3-7/8", 1/2", 4-4-1/2", 5 1/2"- 5 -, 6-6-5/8", 7-5/8 o Hūrae;
Ko te tau tuarua e tohu ana i te momo miro tīwiri (1, 2, 3), 1-- IF; 2--- FH; 3-- REG;
Ko te tau tuatoru e tohu ana i te tāne me te wahine (e tohuhia ana e te 0 me te 1)
0--Pouaka (wahine); 1--Pin (tāne);
4. Ko ētahi atu momo miro tīwiri paipa wiri e whakamahia whānuitia ana ko BTC, MT, AMT, HT55 me ētahi atu.
5. Hei tāpiritanga, ko te momo miro tīwiri noa o te motuka 7-5/8 "REG, 6-5/8" REG, 4-1/2 "REG, kei a ia anō hoki te 4-1/2" IF. Ko te momo miro tīwiri noa o te waru paipa me te tapahi waipēhi ko REG.
