ASTM A299 G.A Mn-Si Alloy Pressure chotengera zitsulo mbale

Chitsulo cha carbon chokhala ndi Manganese-Silicon plate SA299 Grade A,SA299 Grade B under steel specification standard ASME SA 299/SA 299M. Pali magiredi ena awiri achitsulo A299 Grade A ndi A299 Grade B omwe ali ndi chitsulo chofanana ndi ASTM. A 299/A 299M. Ponena za chithandizo cha kutentha, mbale yachitsulo A299 Gulu A ndi A299 Gulu B yofanana ndi pansi pa mamilimita 50 nthawi zambiri imakulungidwa mumkhalidwe wopindika, mbale yachitsulo yoponderezedwa.
Malinga ndi muyezo wa ASTM A299/A299M, mbale yachitsulo A299 Gulu A ndi A299 Gulu B idzasankhidwa muzotsatira zamakono: S1. Chithandizo cha Vacuum, S2. Kusanthula kwazinthu. S3. Kuthandizira kutentha kwa post weld kutentha kwa makuponi oyesa makina, S4. Mayeso owonjezera azovuta, S5. Kuyesa kwamphamvu kwa Charpy V-notch, S6. Kutsika kulemera, S7. Kuyesa kwamphamvu kwa kutentha kwakukulu.

1. Gulu la Zitsulo: A 299 Giredi A, A 299 Gulu B.
2. Kukula (T * W * L): Makulidwe: 8mm mpaka 300mm; m'lifupi: 1500mm kuti 4020mm; Utali: 4000mm kuti 18000mm
3. Adopt Standard: ASTM A299 ndi ASME SA 299.
4. Chithandizo cha Kutentha: Kutentha Kwambiri, CR, Normalized, Kuzimitsidwa, Kutentha, TMCP, Electroslag Remelting Technical.
5. Ntchito Zitsulo: Kudula, Kupenta, Kuphulika kwa Mpira, Kukonzekera ndi Gulu Lachitatu mu gawo la DNV, BV, LR, GL, ABS ndi CCS mu mbale yachitsulo yochuluka kwambiri.

ASTM A299 Giredi A boiler zitsulo mbale, ASME SA299 Gulu A chotengera chopumira mbale zitsulo ndi mfundo za carbon zitsulo ndi Manganese-Silicon. Ponena za mbale yopyapyala ya SA299 Gulu A yomwe idapangidwa kuchokera kuchitsulo chachitsulo SA299 Gulu A ndikuperekedwa popanda chithandizo cha kutentha kapena kungochepetsa kupsinjika kokha, zofunika zowonjezera, kuphatikiza zoyeserera zowonjezera komanso lipoti lazoyeserera zowonjezera zidzagwiritsidwa ntchito pa A20/ A20M zitsulo muyezo.

Zofunikira Zaukadaulo & Ntchito Zowonjezera:

• Kuthamanga kwakukulu
• Mayeso okhudza kutentha kochepa
• Normalized kwa mbale wandiweyani kuposa 40mm
• Simulated post-weld heat treatment (PWHT)
• Satifiketi yoyeserera ya Orginal Mill yoperekedwa pansi pa EN 10204 FORMAT 3. 1/3. 2
• Kuwombera ndi Kupenta, Kudula ndi kuwotcherera malinga ndi zofuna za wogwiritsa ntchito
