Nima uchun reytingda tazyiqlarASTM A269 quvuri?
Astm A269 - bu {{2} sanoat tizimlarida, asosan, asosiy tazyiqli antoskoplar uchun keng qo'llaniladigan maxsus qo'llanilgan, asosan, ARTM A269 quvurining quvvati uchun keng qo'llaniladi, chunki A269 quvurining quvvati quyidagilarga bog'liq:
Tashqi diametri (OD)
Devor qalinligi (WT)
Moddiy baho (e {{{{{{{{{{{{{., TP304, TP316, TP316L)
Harorat
Naychani qurish (uzluksiz yoki payvandlangan)
Astm A269 naychaga qanday baholanganmi?
Hisob-kitoblar Asme B31.3 jarayon inshootiga asoslangan va quyidagi formuladan foydalanadi:
Qayerda:
P= Ishchi bosim (PSI)
S= Dizayn haroratida ruxsat beriladigan stress (PSI)
t= Devor qalinligi (dyuym)
D= tashqi diametr (dyuym)
📌 Welded tubes may have a weld factor applied (typically 0.85 if not full-penetration).
ASTM A269 bosimli tang
Material: TP304 / TP304L
Dizayn harorati: 100 d / f (38 daraja)
Ruxsat beriladigan stress (lar): 20,000 psi
| Naycha hajmi (OD X devor) | Devor (ichiga) | Ish bosimi (PSI) | Portlash bosimi (taxminan {.) |
|---|---|---|---|
| 1/4" x 0.035" | 0.035 | ~7,600 | ~22,800 |
| 1/4" x 0.049" | 0.049 | ~10,400 | ~31,200 |
| 3/8" x 0.035" | 0.035 | ~5,200 | ~15,600 |
| 3/8" x 0.065" | 0.065 | ~9,000 | ~27,000 |
| 1/2" x 0.035" | 0.035 | ~3,700 | ~11,100 |
| 1/2" x 0.065" | 0.065 | ~6,600 | ~19,800 |
| 3/4" x 0.049" | 0.049 | ~2,700 | ~8,100 |
| 3/4" x 0.083" | 0.083 | ~4,500 | ~13,500 |
| 1" x 0.065" | 0.065 | ~2,300 | ~6,900 |
| 1" x 0.109" | 0.109 | ~3,800 | ~11,400 |
Ostenitik zanglamaydigan po'lat uchun harorat
Yuqori haroratda bosim o'tkazishni sozlash uchun quyidagilarni qo'llangHaroratni tuzatish omillari:
| Harorat (f) | Tuzatish faktori |
|---|---|
| 100 daraja F (38 daraja) | 1.00 |
| 200 diplom f (93 daraja) | 0.96 |
| 400 daraja F (204 daraja) | 0.85 |
| 600 daraja F (316 daraja) | 0.76 |
| 800 daraja F (427 daraja) | 0.69 |
Misol:
1/2 "× 0 {. . . 000 PSI F. 100 daraja F. dan 4 da kichik rosti bor.
600 daraja F:
4,000 × 0.76 = 3,040 psi
