Izilinganisi zamapayipi asezingeni eliphansi
1. Isisekelo sentambo kufanele sibe bukhali, size sibe ne-pitch futhi sibukeke sicwebezela.
2. Isisekelo sentambo singathintwa ngesandla, kufanele sibushelelezi futhi sisebenze ngokujwayelekile.
3. Udonga lwangaphambili lomgogodla wokufakwa kwamapayipi wensimbi engagqwali luyunifomu futhi izingxenye zokugeleza zibushelelezi.
4. Izilinganisi zamapayipi zilethwa ngemuva kokwelapha okuqinile, ngakho-ke indawo kufanele ingafakwa.
5. Okuqukethwe kwekhabhoni ephansi, ukumelana nokugqwala, ukumelana ne-oxidation, ukuqina okuqinile, nokumelana okuqinile nengcindezi.
02 okungaphansi insimbi engagqwali threaded ipayipi nokufakwa:
1. Ubuso bushubile, intambo ayibukhali futhi ayijiyile, iphimbo alilingani, kwesinye isikhathi intambo iyalimala, futhi kulula ukuvuza.
Intambo ayicwebezeli
3. Ingaphakathi ligobile, ubukhulu bodonga abalingani, futhi kulula ukuvimba ngemuva koketshezi.
4. Indawo engamampunge, indawo engalashwa, kulula ukuba ne-oxidized
5. Okuqukethwe kwekhabhoni ephezulu, ukugqwala okulula, ukuqina okuncane, namandla aqine okuqina.
