—— Sanonpipe, ʻO kāu mea hoʻolako hilinaʻi o nā paipu kila presisi maʻamau Lūkini

I. ʻIke Kūikawā: Ke Kihi o nā Paipu Humuhumu Anu ʻole o Rusia

GOST 8734-75(inoa piha: Nā paipu kila Seamless i hoʻololi anu ʻia. Range) ʻo ia ka Lūkini (USSR mua)kūlana ana/ʻano like ʻoleno nā paipu kila humuhumu anu a i ʻole i ʻōwili anu ʻia. Ua hoʻomaka ia i ka lā 1 o Ianuali 1977. Uhi ke kūlana i nā paipu humuhumu anu i hana ʻia (i hana ʻia e ka ʻōwili anu a i ʻole ke kahakiʻi anu) me kahika laulā o waho o 1 mm a 200 mma meka mānoanoa o ka paia mai 0.2 mm a i 22 mm.

ʻO ke kaʻina hana huki anu / ʻōwili anu e hāʻawi i nā paipu i ka pololei kiʻekiʻe loa o ka dimensional a me ka maikaʻi o ka ʻili. Ma o ka hoʻololi anu, hoʻomaʻemaʻe ʻia nā ʻano kila, a hoʻomaikaʻi nui ʻia ka nui o ka metala a me nā waiwai mechanical. ʻO kēia ʻenehana hana anu kiʻekiʻe e hoʻolilo i nā paipu i ʻoi aku ka maikaʻi ma mua o nā paipu ʻōwili wela maʻamau ma ke ʻano o nā hoʻomanawanui dimensional, concentricity a me ka hoʻopau ʻana o ka ʻili - e kūpono iā lākou no nā mea hana pololei, nā ʻōnaehana hydraulic, nā ʻano mīkini pololei kiʻekiʻe a me nā noi koi ʻē aʻe he nui.

Hoʻokumu ʻia ke kūlana ma ke kūlana honuaʻO 1483-78a ua ʻāpono ʻia e ke Komite Mokuʻāina o USSR no nā Kūlana ma ka lā 13 ʻOkakopa 1975 (ʻŌlelo Hoʻoholo No. 2604). ʻO ka paʻi kūpono o kēia manawa ka paʻi hou ʻana o 2007.

II. ʻŌnaehana Maʻamau: Ka Pilina Kūlike ma waena o GOST 8734 a me GOST 8733

Ma ka ʻōnaehana kūlana o Rūsia,GOST 8734-75pono e hoʻohana pū ʻia me kāna kikoʻī loea hoaGOST 8733-87(Nā paipu kila hoʻololi anu ʻole - Nā kūlana loea). Hoʻohui pū lākou i kahi kūlana huahana piha no nā paipu kila:

Kūlana Maʻamau	Ka laulā	Kūlana
GOST 8734-75	ʻO ka laulā o ke anawaena o waho, ka moʻo mānoanoa o ka paia, nā ʻae ʻana o ka dimensional, nā ʻano lōʻihi a me nā ʻokoʻa i ʻae ʻia, ke kaumaha kumumanaʻo	"Pehea kona ʻano" - nā ana
GOST 8733-87	Nā papa kila, ka haku mele kemika, nā waiwai mechanical, nā hoʻāʻo hana, nā hoʻāʻo hydraulic, nā lula nānā, ka māka ʻana, ka hoʻopili ʻana	"He aha nā mea a pehea ka ikaika" - nā koi loea

Palapala kūʻaiMa nā palapala ʻenekinia a i ʻole nā ​​kauoha kūʻai,ʻAneʻane pinepine ʻia ʻo GOST 8733 a me GOST 8734 i ʻōlelo pū ʻia.- hana lākou i hui hiki ʻole ke hoʻokaʻawale ʻia.

III. Ka laulā a me ka hoʻokaʻawale ʻana o nā ana

3.1 Ka laulā ana

Uhi ka maʻamau GOST 8734-75 i nā ana aʻe:

Palena	Pae
Anawaena o waho	1 – 200 mm
Mānoanoa o ka paia	0.2 – 22 mm
Lōʻihi (kaulana)	1.5 – 11.5 mika
Ka lōʻihi (paʻa)	4.5 – 9 mika(palena ʻokoʻa +10 mm)

3.2 Ka hoʻokaʻawale ʻana e ka mānoanoa o ka paia

Ma muli o ka lakio o ke anawaena o waho (D) i ka mānoanoa o ka paia (s), ua māhele ʻia nā paipu i ʻehā mau māhele:

Māhele	Laki D/s	Wehewehena
Pā lahilahi loa	D/s > 40	Māmā loa, no nā hana mālama kaumaha
Pā lahilahi	D/s = 12.5 – 40	Nā paipu paia lahilahi maʻamau
Pā mānoanoa	D/s = 6 – 12.5	Ka mana hoʻouka kaua kiʻekiʻe
Pā mānoanoa loa	D/s < 6	Nā noi kaomi koʻikoʻi

3.3 Nā ʻae ʻana o ke anawaena o waho

Ka laulā o ke anawaena o waho (mm)	ʻO ka ʻokoʻa i ʻae ʻia (mm)
4 – 10	±0.15
>10 – 30	±0.30
>30 – 50	±0.40
>50	±0.8%

3.4 Nā ʻae ʻana i ka mānoanoa o ka paia

Ka laulā mānoanoa o ka paia (mm)	ʻO ka ʻokoʻa i ʻae ʻia
≤1.0	±0.12 mm
>1.0 – 5.0	±10%
>5.0	±8%

3.5 Nā koi pololei

Ka laulā o ke anawaena o waho (mm)	Piʻo kiʻekiʻe loa no ka lōʻihi mika
4 – 8	≤ 3 mm
>8 – 10	≤ 2 mm
>10	≤ 1.5 mm

HoʻomaopopoNo nā paipu me ke anawaena o waho he 20-90 mm, he koi pololei koʻikoʻi o≤ 1 mm no ka lōʻihi mikahiki ke ʻaelike ʻia.

IV. Ka Helu ʻana o ke Kaumaha Manaʻo

Hoʻohana ʻo GOST 8734-75 i ke ʻano hana ma lalo nei e helu ai i ke kaumaha kumumanaʻo no ka mika o ka paipu:

M = 0.02466148 × s × (Dₙ − s)

Ma hea:

M= ke kaumaha no ka mika (kg)

Dₙ= ke anawaena waho maʻamau (mm)

s= ka mānoanoa o ka paia (mm)

Ka nui o ke kila= 7.85 g/cm³

Hāʻawi ka pākuʻi maʻamau i nā papa kaumaha piha no nā hui pū ʻana o ke anawaena waho a me ka mānoanoa o ka paia mai 0.3 mm a 24 mm. Nā Laʻana:

No ka paia 30 mm OD × 2.5 mm, ke kaumaha kumumanaʻo ≈ 1.696 kg/m

No ka paia 76 mm OD × 4.0 mm, ke kaumaha kumumanaʻo ≈ 7.102 kg/m

V. Nā Papa Kila i Loaʻa

Wahi a ke kūlana hoa GOST 8733-87, hiki ke hana ʻia nā paipu humuhumu anu mai nā ʻano kalapona a me ke kila kila like ʻole:

Papa kila	ʻAno	Hoʻohana maʻamau
Papa 10, Papa 20	Ke kila kūkulu kalapona kiʻekiʻe	Ka lawe ʻana i ka wai, nā ʻano hana maʻamau
Papa 35, Papa 45	Ke kila kūkulu kalapona kiʻekiʻe	Hana mīkini, nā ʻāpana kūkulu ikaika kiʻekiʻe
09Г2С (09G2S)	Ke kila haʻahaʻa	Hana lawelawe haʻahaʻa-mahana, nā hale ikaika kiʻekiʻe

Ka like ʻana o ka honuaʻO nā paipu humuhumu anu GOST 8734-75 ua like loa ia i ke kaʻina hana a me ka hoʻohana ʻana meASTM A519(paipu mīkini kalapona a me ke kila kila humuhumu ʻole).

VI. Nā Kahua Noi Maʻamau

Mahalo iāpololei kiʻekiʻe o ka dimensional, hoʻopau ʻili laumania a me ka concentricity maikaʻi loa, Hoʻohana nui ʻia nā paipu humuhumu anu GOST 8734-75 i:

Kahua noi	Nā hoʻohana kikoʻī	No ke aha i koho ʻia ai
Mīkini kikoʻī	Nā ʻau pololei, nā paukū hydraulic, nā ʻāpana pneumatic	Pololei kiʻekiʻe, concentricity maikaʻi
Nā ʻōnaehana hydraulic a me pneumatic	Nā paipu ʻaila kiʻekiʻe, nā laina pneumatic	ʻO ka ʻili o loko laumania, ke kū'ē haʻahaʻa o ke kahe
ʻOihana kaʻa	Nā paipu hoʻopūʻiwa haʻalulu, nā paipu kia hoʻokele	ʻO ke ʻano like o ka nui
Kemika ʻaila	Nā paipu mea hana, nā laina trace	Ke kūpaʻa paʻa hilinaʻi
Hana mana	Nā paipu kōkua paila	Hana maikaʻi i ka mahana kiʻekiʻe

Ke hoʻohālikelike ʻia me nā ʻōmole i ʻōwili wela ʻia, ʻo ke kaʻina hana huki anu e ʻoi aku ka maikaʻi o nā ʻōmole GOST 8734-75 i:

Pololei o ke anaʻO ke ahonui OD e like me ka ±0.15 mm (nā nui liʻiliʻi), ʻoi aku ka maikaʻi ma mua o ka ʻōwili wela.

ʻAno o ka ʻiliLaumania i loko a i waho - mākaukau no ka ʻākoakoa pololei me ka ʻole o ka mīkini hou ʻana.

KūlikeʻO ka mānoanoa like o ka paia, kūpono no ka hana pololei ma hope.

VII. Nā Kūlana Kūlike o ka Honua

ʻŌnaehana maʻamau	Kūlana kūlike	Wehewehena
Kina (GB)	GB/T 3639-2021	ʻO nā paipu kila humuhumu anu a i ʻole i ʻōwili anu ʻia
ʻAmelika Hui Pū ʻIa (ASTM)	ASTM A519	ʻO ka paipu mechanical kalapona a me ke kila kila humuhumu ʻole
Rusia (GOST)	GOST 8734-75(nā ana) +GOST 8733-87(nā kūlana loea)	Hoʻohana pū ʻia

memo likeʻO ke kūlana Kina kokoke loa i GOST 8734-75 ʻo iaGB/T 3639-2021(Nā paipu kila humuhumu kikoʻī i huki anu ʻia a ʻōwili anu ʻia paha), kahi e kūlike ai i ka noi (hana anu kikoʻī kiʻekiʻe) a me ke kaʻina hana. Eia kekahi, hiki ke kuhikuhi ʻia ʻo GB/T 8162 (nā paipu humuhumu kūkulu) a me GB/T 8163 (nā paipu humuhumu lawe wai), akā hāʻawi ʻo GB/T 3639 i ka mea kūpono loa i ka pololei a me ke kaʻina hana anu.

VIII. No ke aha e koho ai iā Sanonpipe?

ʻO kā mākou mau pono	Nā kikoʻī
ʻIke loea maʻamau	Ka hoʻomaopopo hohonu ʻana i ka ʻōnaehana GOST 8733/8734 - wehewehe pololei mākou i nā koi maʻamau Lūkini āpau
Hōʻoia waiwai	Piha nā papa i uhi ʻia - 10#, 20#, 45#, 09Г2С, a pēlā aku, me nā palapala hōʻoia lako piha.
Paʻa pono i hōʻoia ʻia	Hana ʻia nā ʻōmole āpau e like me nā koi hoʻomanawanui GOST 8734-75 - pololei ka ana hilinaʻi
Ka laulā piha	Hāʻawi mākou i ka laulā holoʻokoʻa o nā diameters o waho1–200 mma me nā mānoanoa o ka paia0.2–22 mm

Lawelawe hoʻopau a hoʻopau	Mai ka nīnau ʻana, ka wehewehe ʻana i ka ʻenehana a me ka ʻōlelo a hiki i ka palapala a me ka logistics - ka lawe ʻana i hoʻokahi wahi
Kūpaʻa pilikia ʻole	Ma luna o 240 mau wahi nānā mana kūloko, a me nā palapala me ka ʻole o nā ʻokoʻa

IX. Kāhea iā mākou

Ua hoʻolaʻa ʻia ʻo Sanonpipe i ka hāʻawi ʻana i nā paipu kila humuhumu anu GOST 8734-75 kiʻekiʻe i nā mea kūʻai aku ma ka honua holoʻokoʻa. Inā makemake ʻoe i nā paipu mīkini kikoʻī, nā paipu hydraulic a i ʻole nā ​​​​paipu kūkulu, hāʻawi mākou i ke kākoʻo loea ʻoihana a me nā hoʻonā lako maʻalahi.

Laʻana wehewehe kikoʻī maʻamau:

Труба стальная бесшовная холоднодеформированная 57×3.5 ГОСТ 8734-75 / В 20 ГОСТ 8733 87
(ʻO ka paipu kila humuhumu anu 57 × 3.5, nā ana e like me GOST 8734-75, papa kila 20, nā kūlana loea e like me GOST 8733-87)
