Tuubada xariiqda: Waa in la qaado saliidda, gaaska ama biyaha laga soo saaro dhulka una gudbiyo shirkadaha warshadaha saliidda iyo gaaska iyada oo loo marayo tuubada xariiqda. Tuubooyinka xariiqda waxaa ka mid ah tuubooyin aan kala go 'lahayn oo la alxamay. Dhammaadka tuubooyinku waa cidhifyo siman, cidhifyo dun ah iyo cidhifyo godad ah; hababka isku xidhka waa alxanka dhammaadka, isku xidhka isku xidhka, isku xidhka godadka, iwm.

Isticmaalka: Waxaa loo isticmaalaa gaaska, biyaha iyo gaadiidka saliidda ee warshadaha saliidda iyo gaaska

API SEC 5L-2018(Qeexitaanka tuubbooyinka khadka) waxaa soo diyaariyay oo daabacay Machadka Batroolka Mareykanka waxaana si caadi ah looga isticmaalaa adduunka oo dhan.

Sida waafaqsan shuruudaha waxqabadka kala duwan eeGB/T9711-2017Tuubooyinka birta ah ee dhuumaha, tempering-ka waxaa loo qaybin karaa noocyada soo socda iyadoo loo eegayo heerkulka tempering-ka:
1. Heerkulka hooseeya (150-250 digrii)
Qaab-dhismeedka laga helo heerkulka hooseeya waa martensite la qaboojiyey. Ujeeddadiisu waa in la yareeyo cadaadiska gudaha ee daminta iyo jilicsanaanta birta la damiyey iyadoo la ilaalinayo adkaanta sare iyo iska caabbinta xirashada sare ee birta la damiyey, si looga fogaado dildilaaca ama dhaawaca degdega ah inta lagu jiro isticmaalka. Waxaa inta badan loo isticmaalaa qalabka kala duwan ee jarista karbohaydraytka sare leh, qalabka cabbirka, tuubooyinka birta ee dhuumaha GB/T9711, biinanka rogrogaya iyo qaybaha kaarboonaysan, iwm. Adkaanta ka dib daminta guud ahaan waa HRC58-64.
2. Heerkulka dhexdhexaadka ah (250-500 digrii)
Qaab-dhismeedka laga helo heerkulka dhexdhexaadka ah waa troostite la hagaajiyay. Ujeeddadiisu waa in la helo xoog wax soo saar sare, xadka dabacsanaanta iyo adkeysi sare. Sidaa darteed, waxaa inta badan loo isticmaalaa daawaynta tuubooyinka birta ah ee dhuumaha GB/T9711 iyo qaababka shaqada kulul, adkaanta ka dib marka la kululeeyo guud ahaan waa HRC35-50.
3. Heerkulka sare ee kululaynta (500-650 digrii)
Qaab-dhismeedka laga helo heerkulka sare waa troostite la hagaajiyay. Daaweynta kulaylka oo isku daraysa daminta iyo heerkulka sare waxaa badanaa loo yaqaan daawaynta daminta iyo daminta, ujeeddadeeduna waa in la helo sifooyin farsamo oo dhammaystiran oo leh xoog wanaagsan, adkaysi, balaastik iyo adkaysi. Sidaa darteed, waxaa si weyn loogu isticmaalaa qaybaha muhiimka ah ee dhismaha ee baabuurta, tuubooyinka birta ah ee dhuumaha GB/T9711, qalabka mashiinka, iwm., sida ulaha isku xira, boolal, geero iyo shabaqyo. Adkaanta ka dib daminta guud ahaan waa HB200-330.
