— Buku Lofotokozera Zonse za Muyezo ndi Zipangizo za Chitoliro Chopanda Msoko cha ku Russia Chopangidwa ndi Cold-Formed
Chitoliro cha Sanon – Wogulitsa Wanu Wodalirika wa Machubu Achitsulo Olondola a GOST
1. Chidule cha Dongosolo Lokhazikika: Ubale Wogwirizana Pakati pa GOST 8734 ndi GOST 8733
GOST 8734-75 ndiye muyezo wofanana wa mapaipi achitsulo opangidwa ndi kuzizira (okokedwa ndi kuzizira / opindidwa ndi kuzizira) ku Russia (kale USSR). Imafotokoza kutalika kwa mainchesi akunja, makulidwe a khoma, kulekerera kwa miyeso, mitundu ya kutalika ndi kupotoka kololedwa, komanso kulemera kwamalingaliro kwa mapaipi. Njira yokokedwa ndi kuzizira imakwaniritsa kulondola kwakukulu kwa miyeso kuposa mapaipi opindidwa ndi kuzizira, zomwe zimapangitsa kuti ikhale chisankho chabwino kwambiri cha zida zolondola, machitidwe a hydraulic, kapangidwe ka makina kolondola kwambiri, ndi ntchito zina zofanana.
Mu dongosolo la miyezo ya ku Russia, GOST 8734-75 iyenera kugwiritsidwa ntchito pamodzi ndi mikhalidwe yake yaukadaulo yofanana ndi muyezo wa GOST 8733-87. Mwachidule, GOST 8734-75 imafotokoza "momwe chitoliro chimawonekera" (kukula ndi kulekerera), pomwe GOST 8733-87 imafotokoza "momwe chilili ndi mphamvu yake" (kapangidwe ndi magwiridwe antchito).
| Muyezo | Mutu wa Chitchaina | Chigawo |
|---|---|---|
| GOST 8733-87 | Mapaipi achitsulo opanda msoko opangidwa ndi ozizira - Mikhalidwe yaukadaulo | Magiredi achitsulo, kapangidwe ka mankhwala, mawonekedwe a makina, mayeso a njira, mayeso a hydrostatic, malamulo owunikira, kulemba, kulongedza |
| GOST 8734-75 | Mapaipi achitsulo opanda msoko opangidwa ndi ozizira - Mitundu yosiyanasiyana | Kunja kwa mainchesi, makulidwe a khoma, kulekerera kwa miyeso, mitundu ya kutalika ndi kupotoka kololedwa, kulemera kwa chiphunzitso |
Malangizo Ogulira: Mu zikalata za uinjiniya kapena maoda ogulira, GOST 8733 ndi GOST 8734 nthawi zambiri zimatchulidwa pamodzi; amapanga muyezo wathunthu wazinthu za chitoliro.
2. Kufotokozera Zinthu Zatsatanetsatane: Chitsulo 20 (Giredi 20)
Chitsulo 20 (dzina lachi Russia Ст20) ndi chitsulo chapamwamba kwambiri cha kaboni chomwe chimagwiritsidwa ntchito kwambiri motsatira muyezo wa GOST 8734, chomwe chimapereka kuphatikiza koyenera kwa zinthu. Mosiyana ndi chitsulo chotenthedwa cha 20 chomwe chili mu GOST 8731, Chitsulo chozizira cha 20 chimapereka kulondola kwapamwamba komanso khalidwe la pamwamba.
Kapangidwe ka Mankhwala (%)
| Chinthu | Mndandanda wa Zomwe Zili M'kati | Udindo / Zotsatira |
|---|---|---|
| C (Kaboni) | 0.17 – 0.24 | Zimathandiza kuti mphamvu ndi kulimba zikhale bwino |
| Mn (Manganese) | 0.35 – 0.65 | Zimawonjezera mphamvu ndi kuuma |
| Si (Silikoni) | 0.17 – 0.37 | Zimawonjezera kukana kwa okosijeni |

Katundu wa Makina
| Katundu | Mtengo | Muyezo Woyesera |
|---|---|---|
| Mphamvu yokoka (σb) | ≥ 412 MPa | GOST 1497 |
| Mphamvu yobereka (σs) | ≥ 245 MPa | GOST 1497 |
| Kutalika pambuyo pa kusweka (δ5) | ≥ 21% | GOST 1497 |
| Kuuma (HB) | ≤ 156 HB | GOST 9012 |
3. Magawo ndi Kulekerera kwa Miyeso (Chigawo cha GOST 8734-75)
Magawo Ozungulira
Njira yokokera yozizira imapatsa chitolirocho kulondola kwambiri. Kulekerera kwa dayamita yakunja kumatha kufika pa ± 0.15 mm kapena ± 0.8%, kukwaniritsa zofunikira zolimba za makina olondola ndi makina a hydraulic:
| Chizindikiro | Malo ozungulira |
|---|---|
| M'mimba mwake wakunja (OD) | 1 – 200 mm |
| Kukhuthala kwa khoma (WT) | 0.2 – 22 mm |
| Utali | Kutalika kosasinthika 1.5 - 11.5 m; kutalika kosasinthika 4 - 9 m |
Kulekerera kwa M'mimba mwake kwa Kunja
| OD Range (mm) | Kupatuka Kovomerezeka (mm) |
|---|---|
| 5 ≤ OD ≤ 10 | ± 0.15 |
| 10 < OD ≤ 30 | ± 0.30 |
| 30 < OD ≤ 50 | ± 0.40 |
| OD > 50 | ± 0.8% |
Kulekerera kwa Makulidwe a Khoma
| Kulemera kwa thupi (mm) | Kupatuka Kovomerezeka |
|---|---|
| Kulemera ≤ 1 | ± 0.12 mm |
| 1 < Kulemera ≤ 5 | ± 10% |
| Kulemera > 5 | ± 8% |
Zofunikira pa Kuwongoka (pa kutalika kwa mita)
| OD Range (mm) | Kupindika Kwambiri |
|---|---|
| 5 - 8 | ≤ 3 mm |
| 8 - 10 | ≤ 2 mm |
| > 10 | ≤ 1.5 mm |
Dziwani: Pa mapaipi okhala ndi mainchesi 20–90 mm, malire olunjika okhwima angaperekedwe ngati pakufunika mwapadera.
4. Ma Giredi Ofanana Padziko Lonse
Steel 20 ikugwirizana kwambiri ndi magiredi mu miyezo ina yapadziko lonse lapansi, zomwe zimapangitsa kuti pakhale kusankha ndi kusintha padziko lonse lapansi:
| Dongosolo Loyenera | Giredi Yofanana |
|---|---|
| China (GB) | 20# (GB/T 699 chitsulo chapamwamba cha kapangidwe ka kaboni) / 20G (cha ma boiler othamanga kwambiri) |
| USA (ASTM) | A106 Gr.B |
| Japan (JIS) | S20C |
5. Ubwino Waukulu wa Njira Yokokera Zinthu Zozizira
Poyerekeza ndi mapaipi opindidwa ndi kutentha, mapaipi opanda msoko okokedwa ozizira a GOST 8734‑75 amapereka maubwino otsatirawa:
| Ubwino | Kufotokozera Zaukadaulo | Mtengo wa Makasitomala |
|---|---|---|
| Kulondola kwakukulu | Kulekerera kolimba komwe kumachitika chifukwa cha kukoka kozizira | Yoyenera kwambiri makina olondola kwambiri komanso makina oyendetsera ma hydraulic |
| Malo osalala amkati | Kuchepa kwa kuuma kwamkati kumachepetsa kukana kwa madzi | Zimawonjezera magwiridwe antchito mu makina a hydraulic ndi pneumatic |
| Mphamvu yabwino yamakina | Kukwanira kolimba komanso mphamvu yotulutsa mphamvu | Yoyenera kugwiritsidwa ntchito polimbana ndi kupanikizika komanso kapangidwe kake |
| Kukula kwakukulu | OD 1–200 mm, Kulemera 0.2–22 mm | Zimakwaniritsa zosowa zosiyanasiyana za uinjiniya ndi kapangidwe |
6. Magawo Ogwiritsidwa Ntchito Kawirikawiri
Mapaipi opanda msoko a GOST 8734‑75 / Steel 20 opangidwa ndi zitsulo zozizira amagwiritsidwa ntchito kwambiri pazochitika zotsatirazi:
| Malo Ofunsira | Kugwiritsa Ntchito Mwachindunji | Chifukwa Chosankha |
|---|---|---|
| Kuyendera mafuta ndi gasi | Mapaipi otsika mphamvu | Kutha kupotoka bwino, mphamvu yapakati |
| Zipangizo zosinthira kutentha | Mapaketi a chubu chosinthira kutentha / condenser | Kulondola kwakukulu, kusamutsa kutentha bwino |
| Kupanga makina | Zigawo zopangidwa ndi makina, zida zamagalimoto | Kugwira ntchito bwino kwambiri, miyeso yofanana |
| Machitidwe a hydraulic | Mizere yamadzimadzi, mizere yamafuta | Bowo lamkati losalala, kukana madzi pang'ono |
| Mapaipi a mafakitale | Makina ambiri a mapaipi a mafakitale | Kugwira ntchito bwino, kotsika mtengo |
Zipangizozi zimakhala zogwira ntchito bwino komanso zowongoka, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito ponyamula katundu wochepa. Mtundu wa OD wa 10–76 mm ndiye kukula kofala kwambiri kwa mapaipi opanda msoko opangidwa ndi GOST 8734 ozizira.
7. Chitsimikizo cha Ubwino ndi Chithandizo Chotsatira Malamulo a CBAM
Chitsimikizo chadongosolo:
Gulu lililonse limaperekedwa ndi MTC (Mill Test Certificate) yonse.
Zikalata za EN 10204 3.1/3.2 zimapezeka mukapempha.
Kuyang'aniridwa kwa anthu ena ndi SGS, BV, TÜV, ndi zina zotero kumathandizidwa.
Kutsatira kwathunthu kuyambira nambala yosungunuka mpaka chinthu chomalizidwa.
Chithandizo Chotsatira Malamulo a CBAM (Carbon Border Adjustment Mechanism):
Tikhoza kupereka deta yokhudza mpweya woipa womwe umatuluka m'zinthu zathu kutengera muyeso weniweni wa malo.
Thandizo pakukonzekera mapulani owunikira, malipoti otulutsa mpweya, ndi zikalata zina zotsimikizira.
Kukuthandizani kupewa njira yopezera chilango cha mtengo wokhazikika wa EU.
8. N'chifukwa Chiyani Muyenera Kusankha Makampani Opanga Mapaipi a Sanon?
| Mphamvu Zathu | Tsatanetsatane |
|---|---|
| Ukatswiri pa miyezo | Kumvetsetsa mozama kwa dongosolo la GOST 8733/8734; kutanthauzira kolondola kwa zofunikira zaukadaulo zaku Russia |
| Kukhulupirika kwa zinthu zakuthupi | Zikalata zonse za Steel 20; tithanso kupereka zikalata zofanana za GB/ASTM/JIS |
| Kulondola kotsimikizika | Kupanga kumatsatira mosamalitsa zofunikira za GOST 8734‑75 zololera - kulondola kodalirika |
| Kutumiza mwachangu | Chothandizidwa ndi katundu wolemera matani 20,000; maoda ofulumira amatumizidwa mkati mwa masiku 7-15 |
| Thandizo la utumiki wonse | Utumiki wokhazikika kuyambira pa kafukufuku, kufufuza mbiri, mtengo, zikalata, mpaka zinthu zoyendera |
| Kudzipereka kopanda chiopsezo | Malo opitilira 240 owunikira mkati; palibe kusiyana kwa zikalata |
9. Lumikizanani nafe
Sanon Pipe yadzipereka kupereka mapaipi achitsulo opanda zingwe abwino kwambiri okonzedwa ndi GOST kwa makasitomala ku Russia, CIS, ndi kwina. Kaya mukufuna kukula koyenera kapena miyeso yokonzedwa, timapereka chithandizo chaukadaulo chaukadaulo komanso mayankho osinthika azinthu.
Chitsanzo cha kufotokozera kwapadera:
