Machubu otenthetsera otsika ndi apakatikati amapangidwa ndi ma ingots kapena ma billet olimba omwe amabowoleza kuti apange chubu cha burr, kenaka chotentha, chopiringizika kapena chozizira.Wopanda zitsulo chitoliro ali ndi udindo wofunika mu makampani China zitsulo chitoliro.Malinga ndi ziwerengero zosakwanira, China alipo opanda msokonezo chitoliro kupanga mabizinezi pafupifupi 240 kuposa, opanda zitsulo chitoliro unit pafupifupi 250 waika, mphamvu pachaka kupanga pafupifupi matani miliyoni 4.5.Kuchokera pamalingaliro amtundu, <φ76, owerengera 35%, <φ159-650, owerengera 25%.Pankhani ya mitundu, matani 1.9 miliyoni a machubu azinthu zambiri, omwe amawerengera 54%;760,000 matani a machubu a petroleum, owerengera 5.7%;Matani 150,000 a zipilala zama hydraulic, machubu olondola, owerengera 4.3%;machubu osapanga dzimbiri, machubu onyamula, machubu amagalimoto okwana matani 50,000, owerengera 1.4%.
Machubu amawotchi otsika ndi apakatikati: mphamvu zamakokedwe σb (MPa): ≥ 410 (42) zokolola mphamvu σs (MPa): ≥ 245 (25) elongation δ5 (%): ≥ 25 chigawo kutsika ψ (%): ≥ 5 , kuuma: osati kutentha mankhwala, ≤ 156HB, chitsanzo kukula: chitsanzo kukula 25mm mfundo kutentha mankhwala ndi gulu metallographic: specifications kutentha mankhwala: normalized, 910 ℃, mpweya kuzirala.Bungwe la Metallographic: ferrite + pearlite.
Kuphatikizika kwa chubu chapakati komanso chotsika: GB3087-1999 chubu chachitsulo chosasunthika cha boiler yotsika komanso yapakatikati.
Machubu otenthetsera apakati komanso otsika amakhala otentha okulungidwa komanso ozizira (okulungidwa) opanda msokonezo azitsulo zapamwamba za carbon structural zomwe zimagwiritsidwa ntchito popanga machubu otentha kwambiri, machubu amadzi ogudubuza ndi machubu otenthetsera kwambiri opangira ma boilers, machubu akulu a utsi, machubu ang'onoang'ono a utsi ndi arch. machubu a njerwa azinthu zosiyanasiyana zama boilers otsika komanso apakatikati.Amagwiritsidwa ntchito makamaka pama boilers akumafakitale ndi ma boilers okhalamo kuti azinyamula mapaipi amadzimadzi otsika komanso apakatikati.Zoyimira ndi 10 ndi 20 gauge zitsulo.
