I-Sanonpipe – Umhlinzeki Wakho Wepayipi Lensimbi Ejwayelekile Ye-GOST Othembekile Wemakethe YaseRussia
1. Ukubuka konke kweSistimu Yepayipi Yensimbi Engenamthungo YaseRussia i-GOST
Uhlelo olujwayelekile lwe-GOST lwaseRussia lungenye yezindinganiso zezimboni eziqine kakhulu emhlabeni, ezisetshenziswa kabanzi emikhakheni yokukhiqiza uwoyela, igesi, amakhemikhali, amandla, ukwakhiwa, kanye nemishini. Kumapayipi ensimbi angenamthungo ashisayo, amazinga ayinhloko aqukethe ukucaciswa kobukhulu kanye nezimo zobuchwepheshe - kokubili kumele kusetshenziswe ndawonye futhi akuhlukaniseki.
| Okujwayelekile | Igama eligcwele | Inhloso |
|---|---|---|
| I-GOST 8732-78 | Amapayipi ensimbi angenamthungo ashisayo – Ububanzi obunobukhulu | Icacisa ububanzi bangaphandle, ukujiya kodonga, ubude kanye nezinye izilinganiso zobukhulu |
| I-GOST 8731-74 | Amapayipi ensimbi angenamthungo ashisiwe – Izimo zobuchwepheshe | Icacisa ukwakheka kwamakhemikhali, izakhiwo zemishini, imithetho yokuhlola, njll. |
Inothi Elibalulekile: I-GOST 8732-78 izothathelwa indawo yi-GOST 8732-2025 ngomhlaka-1 Mashi 2026. I-sanonpipe ingahlinzeka ngemikhiqizo ehambisana nezindinganiso ezindala nezintsha, iqinisekisa ukuthobela okugcwele kwamaphrojekthi akho.
2. GOST 8732-78: Izinga Elinemininingwane Elinganiselwe
I-GOST 8732-78 isebenza kumapayipi ensimbi angenamthungo asetshenziswa ngokujwayelekile ashisayo aguquliwe (agoqekile ashisayo), akhiqizwa ngokwesilinganiso sangaphandle, ubukhulu bodonga kanye nobude.
Ububanzi obunobukhulu:
Ububanzi obujwayelekile bangaphandle: 32 - 426 mm
Ubukhulu bodonga: kulungiswe ngokwesicelo
Ubude: butholakala ngobude obungahleliwe noma obungaguquki, kufika kumamitha angu-30
Ukubekezelelana kobubanzi bangaphandle:
| Ububanzi be-OD | Ukuphambuka okuvunyelwe |
|---|---|
| 32 – 50 mm | ± 0.5 mm |
| 51 – 219 mm | ± 1% |
Ukubekezelelana kobukhulu bodonga:
| Ububanzi bokujiya kodonga | Ukuphambuka okuvunyelwe |
|---|---|
| 3 – 15 mm | +12.5% / –15% |
| 16 – 30 mm | ± 12.5% |
| 32 – 45 mm | +10% / –12.5% |
3. Incazelo Yensimbi Yokwenziwa 20 (Ст20)
Insimbi 20 (igama lesiRashiya elithi Ст20) iyinsimbi yesakhiwo sekhabhoni esezingeni eliphezulu esetshenziswa kakhulu ezindinganisweni zesiRashiya, esetshenziswa kabanzi kumapayipi okucindezela kanye nezingxenye zesakhiwo.

Izindawo ezijwayelekile zokusetshenziswa
Ngenxa yokusebenza kwayo okuhle kakhulu, amapayipi ensimbi angenamthungo e-Steel 20 asetshenziswa kabanzi kulezi zinsimu ezilandelayo:
Uwoyela negesi: amapayipi okudlulisa uwoyela negesi, ukubhoboza ngomfutho ophezulu
Imboni yamandla: amashubhu ebhoyila, ama-superheater, ama-economizer
Imboni yamakhemikhali: imikhumbi yokucindezela, amapayipi amakhemikhali
Ukwakha kanye nemishini: izakhiwo zokwakha, izingxenye zemishini, amasilinda e-hydraulic
4. Uhlelo Olujwayelekile Olusekelayo
i-sanonpipe inikeza imikhiqizo ngokuhambisana ngokuqinile nohlelo oluphelele lwe-GOST standard, iqinisekisa ukuhambisana okugcwele nezidingo zokufinyelela emakethe yaseRussia:
| Okujwayelekile | Indima |
|---|---|
| I-GOST 8732-78 | Imininingwane yobukhulu (OD, ukujiya kodonga, ubude) |
| I-GOST 8731-74 | Izimo zobuchwepheshe (ukwakheka kwamakhemikhali, izakhiwo zemishini, imithetho yokuhlola) |
| I-GOST 9567-75 | Imininingwane yobukhulu bamapayipi ensimbi anembile kakhulu (lapho kudingeka ukubekezelelana okuqinile) |
Ukuqinisekisa ikhwalithi:
Iqoqo ngalinye linikezwa i-MTC ephelele (Isitifiketi Sokuhlolwa Kwezinto)
Izitifiketi ze-EN 10204 3.1/3.2 ziyatholakala uma ziceliwe
Ukuhlolwa kweqembu lesithathu yi-SGS, i-BV, i-TÜV njll. kuyasekelwa
5. Kungani Ukhetha i-sanonpipe?
| Izinzuzo Zethu | Imininingwane |
|---|---|
| Ubuchwepheshe obujwayelekile | Ukuqonda okujulile kohlelo lwe-GOST - ukuhumusha okunembile kwezimfuneko zobuchwepheshe zaseRussia |
| Isiqinisekiso sezinto ezibonakalayo | I-Steel 20 ihambisana ngokugcwele ne-GOST 8731‑74, elingana ne-ASTM A106 Gr.B |
| Ukulethwa okusheshayo | Kuthenjelwe kumathani angu-20,000 esitokwe esivamile, ama-oda aphuthumayo alethwa ezinsukwini ezingu-7-15 |
| Iphakheji yesevisi ephelele | Kusukela ekubuzeni, ekuhlolweni kwesizinda kanye nesilinganiso kuya kumadokhumenti kanye nezinhlelo zokusebenza - ukulethwa okukodwa |
| Ukuzibophezela okungenangozi | Izindawo zokuhlola zangaphakathi ezingaphezu kuka-240, akukho mehluko kumadokhumenti |
