Sanonpipe - Wogulitsa Mapaipi Anu Odalirika a GOST Standard Steel ku Msika wa ku Russia
1. Chidule cha Dongosolo Lokhazikika la Mapaipi a Chitsulo Chosasemphana la ku Russia la GOST
Dongosolo la GOST la ku Russia ndi limodzi mwa miyezo yokhwima kwambiri ya mafakitale padziko lonse lapansi, lomwe limagwiritsidwa ntchito kwambiri m'magawo opanga mafuta, gasi, mankhwala, mphamvu, zomangamanga, ndi makina. Pa mapaipi achitsulo opindidwa bwino, miyezo yayikulu imakhala ndi mawonekedwe a kukula ndi mikhalidwe yaukadaulo - zonse ziyenera kugwiritsidwa ntchito limodzi ndipo sizingalekanitsidwe.
| Muyezo | Dzina lonse | Cholinga |
|---|---|---|
| GOST 8732-78 | Mapaipi achitsulo osapindika otentha - Magawo amitundu | Imatchula mainchesi akunja, makulidwe a khoma, kutalika ndi magawo ena a kukula kwake |
| GOST 8731-74 | Mapaipi achitsulo osapindika otentha - Mikhalidwe yaukadaulo | Imafotokoza kapangidwe ka mankhwala, makhalidwe a makina, malamulo owunikira, ndi zina zotero. |
Chidziwitso Chofunika: GOST 8732-78 idzasinthidwa ndi GOST 8732-2025 pa Marichi 1, 2026. Sanonpipe ikhoza kupereka zinthu zogwirizana ndi miyezo yakale ndi yatsopano, kuonetsetsa kuti mapulojekiti anu akutsatira malamulo onse.
2. GOST 8732-78: Muyezo Watsatanetsatane wa Miyeso
GOST 8732-78 imagwira ntchito pa mapaipi achitsulo osasinthika omwe amagwiritsidwa ntchito nthawi zonse, opangidwa molingana ndi kukula kwa kunja, makulidwe ndi kutalika kwa khoma.
Magawo osiyanasiyana:
Ma diameter wamba akunja: 32 - 426 mm
Kukhuthala kwa khoma: kusinthidwa malinga ndi momwe ntchito ikuyendera
Kutalika: Kumapezeka m'mautali osasinthika kapena okhazikika, mpaka mamita 30
Kulekerera kwa m'mimba mwake kwakunja:
| Mtundu wa OD | Kupatuka kovomerezeka |
|---|---|
| 32 - 50 mm | ± 0.5 mm |
| 51 – 219 mm | ± 1% |
Kulekerera makulidwe a khoma:
| makulidwe a khoma osiyanasiyana | Kupatuka kovomerezeka |
|---|---|
| 3 - 15 mm | +12.5% / –15% |
| 16 - 30 mm | ± 12.5% |
| 32 – 45 mm | +10% / –12.5% |
3. Kufotokozera kwa Zipangizo za Chitsulo 20 (Ст20)
Chitsulo 20 (dzina lachi Russia Ст20) ndi chitsulo chapamwamba kwambiri chomwe chimagwiritsidwa ntchito kwambiri mu miyezo ya ku Russia, chomwe chimagwiritsidwa ntchito kwambiri mu mapaipi opanikizika ndi zigawo zina za kapangidwe kake.

Madera ogwiritsira ntchito wamba
Chifukwa cha ntchito yake yabwino kwambiri, mapaipi achitsulo opanda msoko a Steel 20 amagwiritsidwa ntchito kwambiri m'magawo otsatirawa:
Mafuta ndi gasi: mapaipi otumizira mafuta ndi gasi, kuboola mokakamiza kwambiri
Makampani opanga magetsi: machubu a boiler, ma superheater, ndi ma economizer
Makampani opanga mankhwala: zombo zopondereza, mapaipi a mankhwala
Kapangidwe ndi makina: nyumba zomangira, zida zamakina, masilinda a hydraulic
4. Njira Yothandizira Yokhazikika
Sanonpipe imapereka zinthu motsatira dongosolo lonse la GOST, kuonetsetsa kuti zikutsatira zonse zomwe zikufunikira pamsika waku Russia:
| Muyezo | Udindo |
|---|---|
| GOST 8732-78 | Mafotokozedwe a miyeso (OD, makulidwe a khoma, kutalika) |
| GOST 8731-74 | Mikhalidwe yaukadaulo (kupanga mankhwala, mawonekedwe a makina, malamulo owunikira) |
| GOST 9567-75 | Mafotokozedwe a miyeso ya mapaipi achitsulo olondola kwambiri (ngati pakufunika kulekerera kolimba) |
Chitsimikizo chadongosolo:
Gulu lililonse limaperekedwa ndi MTC (Chitsimikizo Choyesera Zinthu) chathunthu.
Zikalata za EN 10204 3.1/3.2 zimapezeka mukapempha
Kuyang'aniridwa kwa anthu ena ndi SGS, BV, TÜV ndi zina zotero kumathandizidwa
5. N’chifukwa Chiyani Muyenera Kusankha Sanonpipe?
| Ubwino Wathu | Tsatanetsatane |
|---|---|
| Ukatswiri wokhazikika | Kumvetsetsa kwakukulu kwa dongosolo la GOST - kutanthauzira kolondola kwa zofunikira zaukadaulo zaku Russia |
| Chitsimikizo cha zinthu zakuthupi | Steel 20 ikugwirizana kwathunthu ndi GOST 8731‑74, yofanana ndi ASTM A106 Gr.B |
| Kutumiza mwachangu | Kudalira matani 20,000 a katundu wamba, maoda ofulumira amaperekedwa mkati mwa masiku 7-15 |
| Phukusi la utumiki wonse | Kuyambira pa kafukufuku, kufufuza mbiri ya moyo ndi mtengo wake mpaka zolemba ndi zinthu zomwe zachitika - kutumiza zinthu nthawi imodzi |
| Kudzipereka kopanda chiopsezo | Malo owunikira khalidwe la mkati opitilira 240, palibe kusiyana kulikonse pa zikalata |
| Zobiriwira komanso mpweya wochepa | Malipoti okhudza carbon footprint akupezeka kuti athandizire kutsatira malamulo a ESG |
Chitsanzo cha kufotokozera kwa muyezo:
*Труба стальная бесшовная горячедеформированная 114×6 ГОСТ 8732-78 / В 20 ГОСТ 8731-74*
(Chitoliro chachitsulo chosasunthika chotentha 114×6, chogwirizana ndi muyezo wa GOST 8732‑78, Chitsulo 20, chogwirizana ndi mikhalidwe yaukadaulo ya GOST 8731‑74)
6. Lumikizanani nafe
Sanonpipe yadzipereka kupereka zinthu zapamwamba kwambiri za GOST zokhazikika pa chitoliro chachitsulo kwa makasitomala ku Russia ndi misika ya CIS. Kaya mukufuna zofunikira kapena kukula koyenera, timapereka chithandizo chaukadaulo chaukadaulo komanso njira zosinthira zinthu.
