Sumul karfe bututu kai tsaye tallace-tallace na daban-daban kayan

1.Janar manufa sumul karfe bututu ne birgima da talakawa carbon tsarin karfe, low gami tsarin karfe ko gami tsarin karfe, tare da most fitarwa. Ana amfani da shi galibi azaman bututu ko sassa na tsari don isar da ruwa.

2. Akwai nau'ikan wadata uku bisa ga dalilai daban-daban:

a. Bayarwa bisa ga tsarin sinadaran da kaddarorin inji;

b. Bayarwa bisa ga kayan aikin injiniya;

c.An kawo shi kamar yadda gwajin hydrostatic. Idan bututun ƙarfe da aka kawo bisa ga ajin A da B ana amfani da shi don ɗaukar matsa lamba na ruwa, zai kuma kasance ƙarƙashin gwajin hydrostatic.

3. Bututun da ba su da kyau don dalilai na musamman sun haɗa da bututun da ba su da kyau don tukunyar jirgi, sinadarai da wutar lantarki, bututun ƙarfe don ilimin ƙasa da bututun mai na mai.

Bututun ƙarfe mara ƙarfi yana da ɓangaren rami kuma ana amfani da shi sosai azaman bututun isar da ruwa, kamar bututun isar da mai, iskar gas, gas, ruwa da wasu ƙaƙƙarfan kayan aiki.

① Babban tsarin samarwa na bututun ƙarfe mara nauyi (△ babban aikin dubawa):

Shiri da duba bututu babu △ → dumama bututu blank → perforation → bututu mirgina → reheating na karfe bututu → sized (rage) → zafi magani △ → mikewa gama → gamawa → dubawa △ (nodestruction, jiki da sinadari, benci dubawa ) → ajiyar kaya

② Babban hanyoyin samar da sanyi birgima (jawo) bututun ƙarfe mara nauyi:

Shirye-shirye mara kyau → pickling da lubrication → mirgina sanyi (zane) → maganin zafi → daidaitawa → gamawa → dubawa
