Imibhobho yentsimbi yahlulwe yaba yimibhobho yentsimbi engenamthungo kunye nemibhobho yentsimbi edityanisiweyo (imibhobho ethungelweyo).

Umbhobho we-boiler luhlobo lwetyhubhu engenamthungo. Indlela yokuvelisa iyafana neyombhobho ongenamthungo, kodwa kukho iimfuno ezingqongqo kumabakala ensimbi asetyenziselwa ukuvelisa iipayipi zetsimbi. Ngokweqondo lobushushu bokusetyenziswa, inokwahlulwa ibe ziityhubhu zebhoyila ngokubanzi kunye neityhubhu zebhoyila zoxinzelelo oluphezulu.

I-1) Amabakala ensimbi yensimbi ephezulu ye-carbon structural i-20G, i-20MnG kunye ne-25MnG.

2) I-alloy structural steel grade 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, njl.

Iityhubhu zentsimbi ezingenamthungo zeziBoiler zoxinzelelo oluphantsi noluPhakathi (GB3087-2008), Iityhubhu zentsimbi ezingenamthungo kwiiBoilers zoxinzelelo oluphezulu (GB5310-2008), I-ASME SA-106, I-ASME SA-213, I-ASTM A335

Ukongeza, inkampani yethu ikwasebenzisa imibhobho yentsimbi engenamthungo kwizakhiwo (GB/T 81628163), imibhobho yentsimbi engenamthungo yokuqhekeka kwepetroleum (GB9948), imibhobho yentsimbi engenamthungo yesichumiso soxinzelelo oluphezulu (GB6479), imibhobho yeoyile (API 5L) kunye nemibhobho ye-oyile yesingxobo (I-API 5CT), kunye nokufakelwa kombhobho we-alloy.
