GOST 8733-87	Ma'aunin ƙarfe, abun da ke cikin sinadarai, kaddarorin injiniya, gwaje-gwajen tsari, gwaje-gwajen hydraulic, ƙa'idodin dubawa, alama, marufi	"Wane kayan aiki da kuma yadda yake da ƙarfi" - buƙatun fasaha

Bayanin Siyayya: A cikin takardun injiniya ko odar siye,Kusan koyaushe ana ambaton GOST 8733 da GOST 8734 tare– suna samar da ma'aurata marasa rabuwa.

III. Girman Girma da Rarrabawa

3.1 Kewayon girma

Ma'aunin GOST 8734-75 ya ƙunshi waɗannan girma:

Sigogi	Nisa
Diamita na waje	1 – 200 mm
Kauri a bango	0.2 – 22 mm
Tsawon (bazuwar)	1.5 – 11.5 mita
Tsawon (an gyara)	4.5 – 9 mita(ɓangaren iyaka +10 mm)

3.2 Rarrabawa ta hanyar kauri bango

Dangane da rabon diamita na waje (D) da kauri (s) na bango, an raba bututu zuwa rukuni huɗu:

Nau'i	Rabon D/s	Bayani
Bango mai siriri sosai	D/s > 40	Nauyin nauyi mai sauƙi, don aikace-aikacen ceton nauyi
Sirara-bango	D/s = 12.5 – 40	Bututun bango na al'ada
Bango mai kauri	D/s = 6 – 12.5	Ƙarfin ɗaukar nauyi mafi girma
Bango mai kauri sosai	D/s < 6	Aikace-aikacen matsa lamba mai tsanani

3.3 Juriyar diamita na waje

Kewayon diamita na waje (mm)	Bambancin da aka yarda (mm)
4 – 10	±0.15
>10 – 30	±0.30
>30 – 50	±0.40
>50	±0.8%

3.4 Juriyar kauri bango

Kauri daga bango (mm)	Bambancin da aka yarda da shi
≤1.0	±0.12 mm
>1.0 – 5.0	±10%
>5.0	±8%

3.5 Bukatun daidaito

Kewayon diamita na waje (mm)	Matsakaicin lanƙwasa a kowane mita
4 – 8	≤ 3 mm
>8 – 10	≤ 2 mm
>10	≤ 1.5 mm

BayaniGa bututun da diamita na waje ya kai mm 20-90, akwai buƙatar daidaito mai tsauri.≤ 1 mm a kowace mita tsawonsaza a iya amincewa da shi.

IV. Lissafin Nauyin Ka'ida

GOST 8734-75 yana amfani da dabara mai zuwa don ƙididdige nauyin ka'idar a kowace mita na bututu:

M = 0.02466148 × s × (Dₙ − s)

Ina:

M= nauyi a kowace mita (kg)

Dₙ= diamita na waje mara iyaka (mm)

s= kauri bango (mm)

Karfe mai yawa= 7.85 g/cm³

Manhajar da aka saba amfani da ita tana ba da cikakkun tebura na nauyi don duk haɗuwar diamita na waje da kauri bango daga 0.3 mm zuwa 24 mm. Misalai:

Ga bangon 30 mm OD × 2.5 mm, nauyin ka'ida ≈ 1.696 kg/m

Ga bangon 76 mm OD × 4.0 mm, nauyin ka'ida ≈ 7.102 kg/m

V. Ma'aunin Karfe da ake da su

Dangane da ma'aunin GOST 8733-87, ana iya samar da bututun da ba su da santsi daga nau'ikan ƙarfe na carbon da alloy iri-iri:

Karfe aji	Nau'i	Aikace-aikacen yau da kullun
Aji na 10, Aji na 20	Karfe mai inganci mai ƙarfi	Jigilar ruwa, tsarin gabaɗaya
Aji na 35, Aji na 45	Karfe mai inganci mai ƙarfi	Kera injina, sassan tsarin ƙarfi mai ƙarfi
09Г2С (09G2S)	Ƙananan ƙarfe	Sabis mai ƙarancin zafin jiki, tsarin ƙarfi mai ƙarfi

Daidaito tsakanin ƙasashen duniya: Bututun GOST 8734-75 marasa shinge suna kama da juna a tsari da aikace-aikacen suASTM A519(bututun ƙarfe mara sumul na carbon da ƙarfe mai ƙarfe).

VI. Filayen Aikace-aikace na yau da kullun

Godiya gadaidaito mai girma, kammala saman da santsi da kuma kyakkyawan tsari, Ana amfani da bututun GOST 8734-75 masu santsi waɗanda aka zana da sanyi sosai a cikin:

Filin aikace-aikace	Amfani na musamman	Me yasa aka zaɓa
Injin daidaici	Shafts masu daidaito, silinda na hydraulic, abubuwan da ke cikin iska	Babban daidaito, kyakkyawan haɗin kai
Tsarin na'ura mai aiki da iska (hydraulic & pneumatic systems)	Bututun mai mai matsin lamba mai yawa, layukan iska masu amfani da iska	Sulfur mai santsi a ciki, ƙarancin juriya ga kwarara
