I-ASTM A106 umbhobho woxinzelelo olungenamthungo (ekwaziwa ngokuba ngumbhobho we-ASME SA106) iqhele ukusetyenziswa kulwakhiwo lweoyile nerhasi yokucokisa, izityalo zamandla, izityalo zepetrochemical, iibhoyila, kunye neenqanawa apho imibhobho kufuneka ithuthe ulwelo kunye neegesi ezibonisa ubushushu obuphezulu kunye namanqanaba oxinzelelo. .
I-ASTM A106 Umbhobho woxinzelelo olungenamthungo (ekwabizwa ngokuba yi-ASME SA106 umbhobho) igubungela i-carbon steel engenamthungo umbhobho wodonga oluqhelekileyo lwenkonzo yobushushu obuphezulu.Ifanele ukugoba, ukujika kunye nokusebenza okufanayo kokubumba.
Umbhobho we-ASTM A106 weBanga B ulingana ne-ASTM A53 yeBanga B kunye ne-API 5L B kwindawo yeekhemikhali kunye neempawu zomatshini, ngokubanzi ukusetyenziswa kwe-carbon steel kunye ne-leled amandla angaphantsi kwe-240 MPa, amandla e-tensile 415 Mpa.
Iindlela zovavanyo ze-ASTM A106 A, B, C luvavanyo lokucaba, uvavanyo lwe-hydrostatic, uvavanyo lombane olungonakalisiyo, uvavanyo lwe-Ultrasonic, uvavanyo lwangoku lwe-eddy, uvavanyo lokuvuza kwe-flux, ezi nkqubo zovavanyo ziya kwaziswa okanye kuxoxwe ngazo nomxhasi ukuqinisekisa ukuba luhlobo luni lwe uvavanyo luya kusetyenziswa.
