Ngokutsho kokusetyenziswa kwazo, zinokuthi zihlulwe zibe yimibhobho yokubhobhoza, iikhola zokubhobhoza, iipayipi eziphambili, iibhobho ze-casing kunye nemibhobho ye-sedimentation.

8. Imibhobho yentsimbi engenamthungo yokugrumba undoqo wedayimane (GB3423-82) yimibhobho yentsimbi engenamthungo esetyenziselwa imibhobho yokomba, imibhobho engundoqo kunye neecasing zokomba ongundoqo wedayimani.

9. Umbhobho wokugaya i-oyile (YB528-65) ngumbhobho wensimbi ongenamthungo osetyenziselwa ukugaya ioli kunye nokuqina kwangaphakathi okanye kwangaphandle kuzo zombini iziphelo. Kukho iintlobo ezimbini zemibhobho yentsimbi: i-threaded and non-threaded. Imibhobho ephothiweyo idityaniswe kunye nezihlanganisi, kwaye imibhobho engekho intambo idibaniswe kunye nezixhobo zesixhobo nge-butt welding.

10. Imibhobho yentsimbi yeCarbon engenamthungo yeenqanawa (i-GB5213-85) yimibhobho yentsimbi ye-carbon steel engenamthungo ukwenzela ukuveliswa kweenkqubo zemibhobho ye-Class I-resistant-resistant-resistant systems, i-Class II system-resistant-resistant system piping systems, iibhoilers kunye ne-superheaters. Ubushushu bokusebenza kombhobho wentsimbi yentsimbi engenamthungo eludongeni aludluli kuma-450°C, kunye nobushushu bokusebenza kwentsimbi yentsimbi engenamthungo yodonga lombhobho idlula i-450°C.

11. Umbhobho wensimbi ongenamthungo we-automobile half-shaft casing (GB3088-82) ngumbhobho wensimbi ongenamthungo ogqithisiweyo we-high-quality carbon structural steel kunye ne-alloy structural steel yokwenziwa kwe-automobile half-shaft casing kunye ne-drive axle casing shaft pipe.

12. Imibhobho yeoli enoxinzelelo oluphezulu yeenjini zedizili (GB3093-2002) yimibhobho yentsimbi engenamthungo etsalwa ngokubanda esetyenziselwa ukwenza imibhobho yoxinzelelo oluphezulu kwiinkqubo zokutofa kwenjini yedizili.

13. Iityhubhu zetsimbi ezichanekileyo ezingaphakathi kwidayamitha engenamthungo zehydraulic kunye ne-pneumatic cylinders (GB8713-88) ziityhubhu zentsimbi ezitsalwa ngokubanda okanye eziqengqelekayo ezicolekileyo nezingenamthungo ezinedayamitha ezichanekileyo zangaphakathi zokwenziwa kweesilinda zehydraulic kunye nepneumatic.

14. Umbhobho wensimbi ongenamthungo obandayo okanye obandayo obandayo (i-GB3639-2000) ngumbhobho wensimbi ongenamthungo obandayo okanye opholileyo ococekileyo kunye nomgangatho ophezulu wokuchaneka kunye nokugqiba okulungileyo kwizakhiwo zoomatshini kunye nezixhobo ze-hydraulic.

15. I-Structural steel stainless steel pipe (i-GB / T14975-2002) yi-hot-rolled (i-extrusion, i-extrusion) kunye ne-cold drawn (i-rolled) i-tube yensimbi engenamthungo.
