Izinto ezibalulekileyo ekufuneka ziqwalaselwe xa kuthengwa

1. Cacisa ukulingana kwamaBanga ukuze uphephe ukungangqinelani

Xa utshintsha ipayipi ye-GB/T 8162 ibe yimigangatho ye-ASTM, qinisekisa iimfuno zokusebenza ezipheleleyo. Ukulingana ngokuthe ngqo kusebenza kwimithwalo yesakhiwo esingashukumiyo kuphela; kwiimfuno zobushushu, impembelelo okanye ukugqwala, unyango olongezelelweyo lobushushu kunye ne-NDT kufuneka luchazwe. Ungaze ufake ipayipi yesakhiwo ngokubanzi kwizicelo zenkonzo ekhethekileyo.

2. Cacisa Imeko Yokuhanjiswa kunye Nonyango Lobushushu

I-GB/T 8162 inikezelwa ikwimeko egoqwe ngokuzenzekelayo. Lungelelanisa unyango lobushushu neemfuno ze-ASTM:

I-ASTM A53 Gr.B equivalent: Imeko ye-As-rolled yanele.
I-ASTM A106 Gr.B elinganayo:Iqhelekileukuhanjiswa kuyafuneka.
Inkonzo yomthwalo ophantsi/oguquguqukayo: Imeko eqhelekileyo neyomeleleyo okanye elawulwayo iyacetyiswa ukuze kube nokuqina okuqinisekisiweyo.

3. Qinisekisa iKlasi yoKunyamezelana kweMilinganiselo

Umgangatho uchaza iindidi ezimbini zokunyamezelana:

Udidi oluqhelekileyo: OD ±0.75%, WT +12.5% ​​/ -10%, kwizakhiwo zezakhiwo ngokubanzi.
Udidi oluchanekileyo kakhulu: OD ±0.5%, WT ±10%, kwizakhiwo zoomatshini ezineemfuno zokulingana okuqinileyo. Soloko uchaza udidi lokunyamezela ngokweemfuno zokufakela ukuze uphephe iingxaki zokufaneleka kwindawo.
