ASTM A333/A333M fa'asologa o oloa paipa u'amea seamless ma fa'atomuaga o meafaitino
Aotelega Masani
ASTM A333/A333M o le tulaga fa'atonuina o le "paipa u'amea e leai ni so'oga ma fa'apipi'iina mo le vevela maualalo" ua fa'atulagaina e le American Society for Testing and Materials, lea e talafeagai mo faiga o paipa mamafa i siosiomaga maualalo le vevela.
Fa'asologa o oloa
Tele o le lapo'a
Lapo'a i fafo: 1/8" (10.3mm) ~ 26" (660mm)
Mafiafia o le puipui: SCH 10 ~ SCH 160
Umi: e masani lava 5.8m~12.2m (umi tumau pe umi e le tumau)
Mana'oga mo le fa'atinoga fa'amekanika
| Vasega | Malosiaga o le tensile (MPa) | Malosiaga o le gaosiga (MPa) | Fa'aloloa (%) | Vevela o le su'ega o le a'afiaga |
| Vasega 1 | ≥380 | ≥205 | ≥35 | -45℃ |
| Vasega 3 | ≥450 | ≥240 | ≥30 | -100℃ |
| Vasega 4 | ≥415 | ≥240 | ≥30 | -110℃ |
| Vasega 6 | ≥415 | ≥240 | ≥30 | -45℃ |
| Vasega 7 | ≥485 | ≥315 | ≥30 | -100℃ |
| Vasega 8 | ≥690 | ≥515 | ≥20 | -195℃ |
| Vasega 9 | ≥435 | ≥315 | ≥30 | -110℃ |
| Vasega 10 | ≥450 | ≥260 | ≥30 | -75℃ |
Mana'oga o le faagasologa
Faiga o gaosiga: e leai se so'oga pe fa'apipi'i (ae o le Gr.6 e masani ona mana'omia le leai o se so'oga)
Togafitiga i le vevela: fa'atulagaina pe fa'atulagaina ma fa'amalūlūina
Su'ega e lē fa'aleagaina: 100% su'ega o le ultrasonic po'o le eddy current
Su'ega o le mamafa o le hydraulic: e masani lava 1.5 taimi o le mamafa o le galuega
Fa'avasegaga o meafaitino
O le ASTM A333/A333M e tele ituaiga o meafaitino, ma e eseese le tuufaatasiga o vailaʻau o ituaiga taʻitasi:
1. Vasega 1
Kaponi (C): ≤0.30%
Manganese (Mn): 0.40-1.06%
Fosforus (P): ≤0.025%
Sulfur (S): ≤0.025%
Silikoni (Si): ≥0.10%
2. Vasega 3
E tusa ma le 3.5% le aofaʻi o le Nickel (Ni), ma e sili atu ona malosi i le vevela maualalo.
3. Vasega 6
Kaponi (C): ≤0.30%
Manganese (Mn): 0.29-1.06%
Fosforus (P): ≤0.025%
Sulfur (S): ≤0.025%
Silikoni (Si): ≥0.10%
4. Gr.8
Mea e fai i le uʻamea e le gaoia e le austenitic, e masani lava o le 304 poʻo le 304L
5. Vasega 9
E tusa ma le 1.5% le aofaʻi o le Nickel (Ni), i le va o le Gr.3 ma le Gr.6
6. Gr.10
U'amea fa'a'ele'ele maualalo o lo'o i ai le molybdenum (Mo) e fa'aleleia atili ai le tete'e atu i le 'ele
Va'aiga vevela talafeagai mo vasega ta'itasi
| Vasega | Vevela maualalo o le fa'agaioiga |
| Vasega 1 | -45℃ |
| Vasega 3 | -100℃ |
| Vasega 4 | -110℃ |
| Vasega 6 | -45℃ |
| Vasega 7 | -100℃ |
| Vasega 8 | -195℃ |
| Vasega 9 | -110℃ |
| Vasega 10 | -75℃ |
Fa'amatalaga fa'aopoopo
1. O le Gr.6 o le vasega e sili ona faʻaaogaina lautele, aemaise lava e talafeagai mo siosiomaga maualalo le vevela e pei o le LNG (-162 ℃)
2. O le filifilia o vasega eseese e faʻalagolago i le vevela o le mamanu, uiga o le feololo ma le tau o le gaosiga
3. O vaega uma o paipa uʻamea e faia i ai suega o le aʻafiaga i le vevela maualalo e faʻamaonia ai lo latou malosi
4. Mo paipa u'amea ua fa'apipi'iina, e mana'omia le togafitiga vevela talafeagai pe a uma ona fa'apipi'iina e toe fa'afo'isia ai meatotino o meafaitino
5. A faʻatau, e tatau ona filifilia le vasega talafeagai o meafaitino e tusa ai ma le siosiomaga faʻaoga patino, ma e tatau ona faʻamaonia ma le faʻamaoni le tusi faamaonia o meafaitino ma le lipoti o suʻega.
