Chubu cha boiler chili chotseguka mbali zonse ziwiri ndipo chili ndi gawo lopanda kanthu, kutalika ndi kuzungulira kwa chitsulo chachikulu, malinga ndi njira zopangira zitha kugawidwa m'zigawo za chitoliro chachitsulo chosasunthika ndi chitoliro chachitsulo chosungunuka, tsatanetsatane wa chitoliro chachitsulo chokhala ndi miyeso yonse (monga m'mimba mwake kapena kutalika) ndi makulidwe a khoma, adati kukula kwake ndi kwakukulu kwambiri, kuyambira m'mimba mwake waung'ono mpaka mamita angapo m'mimba mwake, chitoliro chachikulu m'mimba mwake.

Machubu achitsulo angagwiritsidwe ntchito popangira mapaipi, zida zotenthetsera, makampani opanga makina, kufufuza za geology ya mafuta, zotengera, makampani opanga mankhwala ndi ntchito zapadera.

(1) Chitsulo chapamwamba kwambiri cha kaboni chopangidwa ndi chitsulo 20G, 20MnG, 25MnG.

(2) Chitsulo cha kapangidwe ka alloy 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, ndi zina zotero.

Boiler chubu imagawidwa m'magulu awiri:GB/T3087-2018chubu cha boiler chapakati ndi chotsika,GB/T5310-2018Chitoliro cha boiler champhamvu kwambiri. Zinthu zathu zazikulu ndi izi:

ASTMA210(A10M)-2012Boiler yachitsulo chapakati cha carbon ndi chitoliro chachitsulo chosasunthika cha superheater, chinthu chachikulu ndi SA210 GrA1, SA210GrC;

ASME SA106/SA-106M-2015, zipangizo zazikulu ndi GR.B gr.C;

ASME/SA SA – 213-213 – m, zinthu zodziwika bwino za aloyi: T11, T12, T22 ndi T23, T91, P92, T5, T5b, T9, T21, T22, T17;

ASTM A335 / A335M – 2018, zipangizo zazikulu ndi izi: P11, P12, P22, P5, P9, P23, P91, P92, P2, ndi zina zotero.
