uhlobo E: Electric-resistant-welding | A kunye no-B | |||
Qaphela: Yomibini imigangatho ivumela ukunikezelwa kombhobho kunye neminye imilinganiselo nje ukuba ihlangabezana nazo zonke ezinye iimfuno zekhowudi. |
IiMfuno zoNyango loBubushushu
I-ASTM A106
Kufuneka iphathwe ubushushu, ngokuqhelekileyo ngokulungiswa (inkqubo yokufudumeza ngaphezu kweqondo lokushisa elibalulekileyo kunye nokupholisa kwiqondo lokushisa eliphakathi).
Umbhobho oshushu oshushu: awufuni unyango lobushushu.Xa umbhobho oshushu esongwayo uphathwa ubushushu, uya kunyangwa ubushushu obukwi-1200 °F [650 °C] okanye ngaphezulu.
Umbhobho otsalwa ngokubanda: uyakunyangwa ubushushu obukwi-1200 °F [650 °C] okanye ngaphezulu emva kwenkqubo yokuzoba ebandayo yokugqibela.
I-ASTM A53
Uhlobo E, iBanga B, kunye noHlobo F, iBanga B: iya kunyangwa ubushushu emva kokuwelda ukuya ubuncinane kwi-1000 °F [540°C] ukuze kungabikho i-martensite enganyangekiyo ekhoyo, okanye iphathwe ngenye indlela ukuze kungabikho i-martensite enganyangekiyo ikhona.
Uhlobo lwe-S: Unyango lobushushu alufunwa kumbhobho ongenamthungo.
Amacandelo eMichiza
Xa uhlalutya ukubunjwa kweekhemikhali ze-ASTM A53 kunye ne-ASTM A106 tubing, iiyantlukwano ezininzi eziphambili zinokuqatshelwa.I-ASTM A106 ichaza umxholo we-silicon (Si) ongekho ngaphantsi kwe-0.10%, enegalelo ekusebenzeni kwayo kumaqondo obushushu aphakamileyo, okwenza ukuba ifaneleke ngokukodwa ukusetyenziswa kwiindawo ezinobushushu obuphezulu njengaleyo kushishino lwepetrochemical kunye neenkqubo zokuhambisa umphunga.
Ngomxholo wekhabhoni (C), umgangatho we-ASTM A53 uchaza umda ophantsi ongaphezulu, ngakumbi kumabakala A kunye no-B odidi lwe-S kunye noHlobo lwe-E. Oku kwenza iibhubhu ze-A53 zifaneleke ngakumbi kwi-welding kunye nokusebenza okubandayo kwaye ngoko zihlala zisetyenziselwa ukwakhiwa kunye nolwelo. iinkqubo zothutho, ezifana nemibhobho yamanzi negesi.
Ngokubhekiselele kumxholo we-manganese (Mn), i-ASTM A106 inikeza uluhlu olubanzi lweBanga B kunye ne-C, elivumela ukunyuka kokuguquguquka kwinkqubo yokuvelisa ngelixa uphucula amandla.Umbhobho we-A53, ngakolunye uhlangothi, ukhawulelwe kumda ophezulu ophezulu womxholo we-manganese, oququzelela ukuzinza ngexesha le-welding.
