Ubalulo lwemveliso yosetyenziso olwahlukileyo lombhobho wentsimbi engenamthungo (2)

9. Umbhobho wentsimbi engenamthungo GB / T8162-1999, inombolo yentsimbi: 10 #, 20 #, 35 #, 45 # kunye ne-16Mn

(Q345), Inkcazo: 6-720 * 1-70mm

10. Umbhobho wensimbi ongenamthungo wokuhambisa ulwelo lwe-GB / T8163-1999, inombolo yentsimbi: 10 #, 20 #, 16Mn (Q345),

Iinkcukacha: 6-720 * 1-70mm

11. Ityhubhu yebhoyila yoxinzelelo oluphantsi-ophakathi GB3087-1999, intsimbi No.: 10 #, 20 #, inkcazo: 6-720 * 1-70mm

12. Umbhobho webhoyili woxinzelelo oluphezulu lwe-GB5310-1995, intsimbi yeNombolo: 20G, inkcazo: 6-720 * 1-70mm.

“kwaye” DN ” -njengaye zisetyenziswa ukubonisa i-diameter, umahluko uthi:

"" iphawula i-diameter yesangqa esiqhelekileyo, okanye i-diameter yangaphandle yombhobho iphindaphindwe ngobuninzi bodonga, njengale: φ25 × 3 iphawula i-diameter yangaphandle

Umbhobho we-25mm kunye ne-3mm yodonga lwamadonga;I-“DN”: ubizo lwegama lofakelo olufana nemibhobho kunye neevalvu

Umendo, ngokuqhelekileyo usondele kwi-diameter yangaphakathi.Ligama eliqhelekileyo elisungulwe ngenjongo yokufakelwa kwezixhobo zobunjineli.

Kuthetha i-diameter yangaphandle, kwaye i-DN ibhekisela kwi-diameter yangaphakathi ye-DN: i-diameter ye-nominal: i-diameter yangaphandle

Ngoku imibhobho--.njengakwi-intshi, iimilimitha luqikelelo olungaphezulu, kulula ukukhumbula inani.

Umzekelo, umbhobho we-DN50 kufuneka ube yi-intshi ezi-2, i-intshi eyi-1 = 25.4mm, i-intshi ezi-2 kufuneka ibe yi-50mm,

Ngeli xesha, ubukhulu bodonga lombhobho, umbhobho ojikelezayo ungaphezulu kwe-5mm, uthatha i-5mm njengomzekelo.

I-diameter yangaphandle ye-tube ye-DN50 kufuneka ibe malunga ne-60mm.

I-Q345 umbhobho wentsimbi ongenamthungo ngokwenene luhlobo lwemathiriyeli yombhobho wentsimbi.Q imele isivuno sesi sixhobo,

Yileta yokuqala yepinyin, ilandelwa yinombolo 345, ebhekisela kwixabiso lemveliso yale nto.

Ngaphakathi okanye malunga ne-345.Kwaye iyancipha inani njengoko ubukhulu bezinto eziphathekayo bukhula.

Iklasi efanayo kwindlela yokubiza amagama kwiklasi ye-Q235.

Q345A,Q345B,Q345C,Q345D,Q345E.Lo ngumahluko wamabanga, amelwe ngamabakala

Ikakhulu, na ifuthe lobushushu yahlukile kwaye!

Q345A, akukho mpembelelo;I-Q345B, i-20 degrees impembelelo yobushushu;Q345C, yi-0

Impembelelo yesidanga;Inqanaba le-Q345D, liyimpembelelo ye-20 degree;Inqanaba le-Q345E, yi-40 degree impact.Ngokwahlukileyo

Ubushushu bempembelelo, ixabiso lempembelelo nalo lahlukile..

Kwi-plate, luhlu lwe-alloy ephantsi.Kwizinto eziphantsi kwe-alloy, le nto ixhaphake kakhulu.

I-Q345 ipayipi yensimbi engenamthungo kwixesha elidlulileyo ibizwa ngokuba yi-16Mn ipayipi yensimbi engenamthungo.

Umgangatho wokuphunyezwa wangaphandle we-Q345 umbhobho wensimbi ongenamthungo ngu: GB709, kunye nomgangatho wokuphunyezwa kwangaphakathi ngu:

GB/T1591-94
