Paipu astm a335 P91 jẹ Pipe ti ko ni ailopin ti a tumọ fun awọn ohun elo iwọn otutu giga. Awọn paipu wọnyi ni a ṣe lati Alloy-Steel ferritic.
Kemikali a335 P91 paipu welded ni awọn eroja bii Molybdenum (Mo) ati Chromium ti a ṣafikun si alloy naa. Nigbati Molybdenum
ati chromium ti wa ni afikun si alloy, ilosoke ninu agbara fifẹ ti sa335 grade P91 pipe. Agbara fifẹ ti
paipu P91 a335 jẹ 415 Mpa, lakoko ti agbara ikore rẹ jẹ 205 Mpa. Iwọn elongation ti paipu awọn sakani laarin 20% si 30%.
Alloy Steel P91 Awọn paipu Alailẹgbẹ ni igbagbogbo tọka si bi irin ti o dara julọ nitori ilodisi ti o pọ si si ipata kiloraidi ti o jẹ ki o jẹ pupọ.
ohun elo to dara fun lilo ni awọn agbegbe omi iyo.
