There are several types of pipe tempering

Marka loo eego GB/T9711.1 dhuunta dhuumaha birta shuruudaha waxqabadka, marka loo eego heerkulka heerkulka kala duwan, waxaa loo qaybin karaa noocyada soo socda ee heerkulka:

[1] Heerkul hooseeya (150-250 darajo)
Qaab-dhismeedka yar-yar ee lagu helo heerkulka hooseeya waa martensite.Ujeeddadeedu waa in la yareeyo walbahaarka deminta iyo jajabnaanta birta adag iyada oo laga duulayo ilaalinta adkaanteeda sare iyo adkaysiga xidhashada sare, si looga fogaado dildilaac ama dhaawac degdeg ah inta lagu jiro isticmaalka.Waxaa inta badan loo isticmaalaa dhammaan noocyada kala duwan ee qalabka goynta kaarboon sare, qalabka cabbirka, GB / T9711.1 tuubbooyinka birta birta, biraha duuban iyo qaybaha carburizing, iwm.

[2] Heerkul dhexdhexaad ah (250-500 digrii)
Qaab-dhismeedka yar-yar ee lagu helo heerkulka dhexdhexaadka ah waa trostite.Ujeeddadu waa in la helo xoog wax-soo-saar sare, xadka laastikada iyo adkaanta sare.Sidaa darteed, waxaa inta badan loo isticmaalaa dhammaan noocyada GB/T9711.1 tuubbooyinka birta iyo daaweynta caaryada kulul, ka dib markii ay adag tahay tempering guud ahaan waa HRC35-50.

[3] Heerkul sarreeya (500-650 digrii)
Qaab-dhismeedka yar-yar ee lagu helo kulaylka sare ee heerkulka ayaa ah mid xanaaqsan.Caadi ahaan, daawaynta kulaylka ee lagu daray deminta iyo xanaaqa waxa loo yaqaan deminta iyo xanaaqa.Ujeeddadeedu waa in la helo sifooyin farsamo oo dhammaystiran oo ka wanaagsan xoogga, qallafsanaanta, caagga iyo adkaanta.Sidaa darteed, waxaa si ballaaran loo isticmaalaa in baabuurta, GB / T9711.1 dhuumaha birta birta ah, qalabka mashiinka iyo qaybaha kale ee muhiimka ah ee dhismaha, sida isku xirka usha, bolt, marsho iyo shaft.Adayga ka dib xanaaqa guud ahaan waa HB200-330.
