ASTM A333/A333M magawo azinthu zachitsulo chosasunthika komanso chiyambi cha zinthu
Chidule Chachikulu
ASTM A333/A333M ndi muyezo wa "chitoliro chachitsulo chosasunthika komanso cholumikizidwa cha kutentha kochepa" wopangidwa ndi American Society for Testing and Materials, womwe ndi woyenera makina opopera mphamvu m'malo otentha pang'ono.
Magawo azinthu
Kukula kwa mitundu
M'mimba mwake wakunja: 1/8" (10.3mm) ~ 26" (660mm)
Kukhuthala kwa khoma: SCH 10 ~ SCH 160
Kutalika: nthawi zambiri 5.8m ~ 12.2m (kutalika kokhazikika kapena kutalika kosakhazikika)
Zofunikira pakugwira ntchito kwa makina
| Giredi | Mphamvu yokoka (MPa) | Mphamvu yotulutsa (MPa) | Kutalika (%) | Kutentha kwa mayeso a mphamvu |
| Gr.1 | ≥380 | ≥205 | ≥35 | -45℃ |
| Gr.3 | ≥450 | ≥240 | ≥30 | -100℃ |
| Gr.4 | ≥415 | ≥240 | ≥30 | -110℃ |
| Gr.6 | ≥415 | ≥240 | ≥30 | -45℃ |
| Gr.7 | ≥485 | ≥315 | ≥30 | -100℃ |
| Bwino | ≥690 | ≥515 | ≥20 | -195℃ |
| Gr.9 | ≥435 | ≥315 | ≥30 | -110℃ |
| Gr.10 | ≥450 | ≥260 | ≥30 | -75℃ |
Zofunikira pa ndondomeko
Njira yopangira: yopanda msoko kapena yolumikizidwa (koma Gr.6 nthawi zambiri imafuna yopanda msoko)
Chithandizo cha kutentha: kusinthasintha kapena kusinthasintha ndi kutentha
Kuyesa kosawononga: Kuyesa kwa 100% kwa ultrasound kapena eddy current
Kuyesa kwa kuthamanga kwa hydraulic: nthawi zambiri kuchulukitsa kuthamanga kwa ntchito 1.5
Kugawa zinthu
ASTM A333/A333M ili ndi mitundu yosiyanasiyana ya zinthu, ndipo kapangidwe ka mankhwala a mtundu uliwonse ndi kosiyana:
1. Chigawo 1
Kaboni (C): ≤0.30%
Manganese (Mn): 0.40-1.06%
Phosphorus (P): ≤0.025%
Sulfure (S): ≤0.025%
Silikoni (Si): ≥0.10%
2. Chigawo 3
Kuchuluka kwa nickel (Ni) kuli pafupifupi 3.5%, ndipo kutentha kwake kumakhala kotsika kwambiri.
3. Chigawo 6
Kaboni (C): ≤0.30%
Manganese (Mn): 0.29-1.06%
Phosphorus (P): ≤0.025%
Sulfure (S): ≤0.025%
Silikoni (Si): ≥0.10%
4. Chigawo 8
Chitsulo chosapanga dzimbiri cha Austenitic, nthawi zambiri chimakhala 304 kapena 304L
5. Gr.9
Kuchuluka kwa nikeli (Ni) kuli pafupifupi 1.5%, pakati pa Gr.3 ndi Gr.6
6. Gr.10
Chitsulo chopanda aloyi chokhala ndi molybdenum (Mo) kuti chiwonjezere kukana dzimbiri
Kutentha komwe kumagwiritsidwa ntchito pa kalasi iliyonse
| Giredi | Kutentha kocheperako kogwira ntchito |
| Gr.1 | -45℃ |
| Gr.3 | -100℃ |
| Gr.4 | -110℃ |
| Gr.6 | -45℃ |
| Gr.7 | -100℃ |
| Bwino | -195℃ |
| Gr.9 | -110℃ |
| Gr.10 | -75℃ |
Kufotokozera kwina
1. Gr.6 ndiye giredi yomwe imagwiritsidwa ntchito kwambiri, makamaka yoyenera malo otentha kwambiri monga LNG (-162℃)
2. Kusankha mitundu yosiyanasiyana kumadalira kutentha kwa kapangidwe kake, mawonekedwe apakati ndi mtengo wake
3. Mapaipi onse achitsulo amayesedwa kutentha kochepa kuti atsimikizire kulimba kwawo
4. Pa mapaipi achitsulo olumikizidwa, kutentha koyenera kumafunika mukamaliza kuwotcherera kuti mubwezeretse katundu wa zinthuzo
5. Pogula, kalasi yoyenera ya zinthu iyenera kusankhidwa malinga ndi malo enieni ogwiritsira ntchito, ndipo satifiketi ya zinthu ndi lipoti loyesa ziyenera kutsimikiziridwa mosamalitsa.
