There are several types of pipe tempering

Ukurikije GB / T9711.1 imiyoboro ikora ibyuma bisabwa gukora, ukurikije ubushyuhe butandukanye, birashobora kugabanywa muburyo bukurikira:

Ubushyuhe buke (dogere 150-250)
Microstructure yabonetse kubushyuhe buke ni tempered martensite.Intego yacyo ni ukugabanya imihangayiko yo kuzimya hamwe nubugome bwibyuma bikomye hashingiwe ku gukomeza ubukana bwayo bwinshi no kwihanganira kwambara cyane, kugirango wirinde guturika cyangwa kwangirika imburagihe mugihe ukoresheje.Ikoreshwa cyane cyane muburyo bwose bwibikoresho byo gukata karubone ndende, ibikoresho byo gupima, GB / T9711.1 umuyoboro wibyuma byumuyoboro, ibyuma bizunguruka hamwe nibice bya carburizing, nibindi, ubukana nyuma yubushyuhe ni RUSANGE HRC58-64.

[2] Ubushyuhe buringaniye (dogere 250-500)
Microstructure yabonetse kubushyuhe buringaniye irangwa na trostite.Ikigamijwe ni ukubona umusaruro mwinshi, imipaka ntarengwa no gukomera.Kubwibyo, ikoreshwa cyane cyane muburyo bwose bwa GB / T9711.1 umuyoboro wibyuma no kuvura ibishyushye, nyuma yubushyuhe bukabije ni HRC35-50.

Ubushyuhe bwo hejuru (dogere 500-650)
Microstructure yabonetse kubushyuhe bwo hejuru ubushyuhe bwitondewe.Mubisanzwe, kuvura ubushyuhe hamwe no kuzimya no gutwarwa byitwa kuzimya no gutuza.Intego yacyo ni ukubona uburyo bwuzuye bwubukanishi bwimbaraga, gukomera, plastike no gukomera.Kubwibyo, ikoreshwa cyane mumodoka, GB / T9711.1 umuyoboro wicyuma, ibikoresho byimashini nibindi bice byingenzi byubaka, nko guhuza inkoni, bolt, ibikoresho na shaft.Gukomera nyuma yo kurakara muri rusange HB200-330.
