Sanonpipe - Mutengesi Wako weGoST Standard Steel Pipe Akavimbika weMusika weRussia
1. Pfupiso yeRussian GOST Seamless Steel Pipe Standard System
Sisitimu yeRussia GOST standard ndeimwe yemitemo yeindasitiri yakaoma kwazvo pasi rose, inoshandiswa zvakanyanya muzvikamu zvekugadzira mafuta, gasi, makemikari, simba, kuvaka, uye michina. Kune mapaipi esimbi asina musono anopisa, mitemo mikuru inosanganisira zviyero zvehukuru nemamiriro ehunyanzvi - ese anofanira kushandiswa pamwe chete uye haaparadzanise.
| Zvakajairika | Zita rizere | Chinangwa |
|---|---|---|
| GOST 8732-78 | Mapaipi esimbi asina musono anopisa - Dimensional range | Inotsanangura dhayamita yekunze, ukobvu hwemadziro, kureba uye zvimwe zviyero zvehukuru |
| GOST 8731-74 | Mapaipi esimbi asina musono anopisa - Mamiriro ehunyanzvi | Inotsanangura kuumbwa kwemakemikari, hunhu hwemakanika, mitemo yekuongorora, nezvimwewo. |
Chinyorwa Chinokosha: GOST 8732-78 ichatsiviwa neGOST 8732-2025 musi wa1 Kurume, 2026. Sanonpipe inogona kupa zvigadzirwa zvinoenderana nezvinodiwa zvekare nezvitsva, zvichiita kuti mapurojekiti ako anyatsotevedzera zvinodiwa.
2. GOST 8732-78: Chiyero cheDimensional chakadzama
GOST 8732-78 inoshanda kumapaipi esimbi asina musono anoshandiswa pakupisa (akamoneredzwa nekupisa), akagadzirwa zvichienderana nedhayamita yekunze, ukobvu hwemadziro uye kureba.
Rudzi rwemhando:
Dhayamita dzekunze dzakajairika: 32 - 426 mm
Ukobvu hwemadziro: hwakagadziriswa zvichienderana nekushandiswa
Kureba: kunowanikwa muhurefu hwakasiyana-siyana kana hwakatarwa, kusvika pamamita makumi matatu
Kushivirira kwedhayamita yekunze:
| Rudzi rweOD | Kutsauka kunobvumidzwa |
|---|---|
| 32 - 50 mm | ± 0.5 mm |
| 51 – 219 mm | ± 1% |
Kushivirira ukobvu hwemadziro:
| Ukobvu hwemadziro | Kutsauka kunobvumidzwa |
|---|---|
| 3 - 15 mm | +12.5% / –15% |
| 16 - 30 mm | ± 12.5% |
| 32 - 45 mm | +10% / –12.5% |
3. Tsananguro yesimbi yezvinhu 20 (Ст20)
Simbi 20 (zita rechiRussian Ст20) ndiyo simbi yemhando yepamusoro inoshandiswa zvakanyanya mumatanho ekuRussia, inoshandiswa zvakanyanya mupombi dzemhepo uye zvikamu zvechimiro.

Nzvimbo dzakajairika dzekushandisa
Nekuda kwekushanda kwayo kwakanaka, mapaipi esimbi eSteel 20 asina musono anoshandiswa zvakanyanya muminda inotevera:
Oiri negasi: mapaipi ekufambisa mafuta negasi, kuchera dhiri rine simba guru
Indasitiri yemagetsi: machubhu ebhoyira, ma superheater, economizers
Indasitiri yemakemikari: midziyo yekumanikidza, mapaipi emakemikari
Kuvaka & michina: zvivakwa zvekuvaka, zvikamu zvemakanika, masirinda ehydraulic
4. Sisitimu Inotsigira
sanonpipe inopa zvigadzirwa zvinoenderana nehurongwa hwakazara hweGOST, ichiva nechokwadi chekuti zvinodiwa pamusika weRussia zvinotevedzwa zvizere:
| Zvakajairika | Basa |
|---|---|
| GOST 8732-78 | Zvimiro zvehukuru (OD, ukobvu hwemadziro, kureba) |
| GOST 8731-74 | Mamiriro ehunyanzvi (kuumbwa kwemakemikari, hunhu hwemakanika, mitemo yekuongorora) |
| GOST 9567-75 | Zvimiro zvemapombi esimbi akanyatsogadzirwa (kana zvichidikanwa kuti pave nekukwanisa kushivirira kwakasimba) |
Simbiso yemhando yepamusoro:
Batch yega yega inopihwa MTC yakazara (Material Test Certificate)
Zvitupa zveEN 10204 3.1/3.2 zvinowanikwa kana zvakumbirwa
Kuongororwa kwevamwe vanhu neSGS, BV, TÜV nezvimwewo kunotsigirwa
5. Sei Uchifanira Kusarudza Sanonpipe?
| Zvakanakira Zvedu | Zvidimbu |
|---|---|
| Unyanzvi hwemazuva ose | Kunzwisisa kwakadzama kwehurongwa hweGOST - kududzirwa kwakarurama kwezvinodiwa zvehunyanzvi zveRussia |
| Vimbiso yezvinhu | Steel 20 inoenderana zvizere neGOST 8731‑74, yakaenzana neASTM A106 Gr.B |
| Kutumira nekukurumidza | Tichivimba nematani zviuru makumi maviri ezvekudya zvenguva dzose, maodha ekukurumidzira anouya mukati memazuva manomwe kusvika gumi nemashanu |
| Pakeji yebasa rakazara | Kubva pakubvunza, kuongorora nhoroondo uye quotation kusvika kumagwaro ne logistics - kuendesa zvinhu panzvimbo imwe chete |
| Kuzvipira kusina njodzi | Nzvimbo dzekutarisa dzemukati dzinopfuura 240, hapana musiyano pamagwaro |
| Girini uye kabhoni shoma | Mishumo yezviratidzo zvecarbon footprint yezvigadzirwa iripo kutsigira kutevedzera ESG |
Muenzaniso wetsananguro yezvakajairwa:
*Труба стальная бесшовная горячедеформированная 114×6 ГОСТ 8732-78 / В 20 ГОСТ 8731-74*
(Pombi yesimbi isina musono inopfurwa inopisa 114×6, inoenderana nechiyero cheGOST 8732‑78, zvinhu zveSimbi 20, inoenderana nemamiriro ehunyanzvi eGOST 8731‑74)
6. Taura Nesu
Sanonpipe yakazvipira kupa zvigadzirwa zvemhando yepamusoro zveGOST zvemapaipi esimbi asina musono kune vatengi vari muRussia nemisika yeCIS. Kunyangwe muchida zvakajairwa kana saizi dzakagadzirwa, tinopa rutsigiro rwehunyanzvi uye mhinduro dzekushandisa dzinochinjika.
