316 Loaʻa iā 2-3% molybdenum (hele i loko 304), ka hoʻonuiʻana i kāna pren mai 18-20 a 24-26.
Hana kēia 316 kū i loko 100+ ppm choride (vsa. 50 ppm no 304), Kūpono kūpono no nā noi / nā noi. 304 is ~ 15% cheaper a kūpono kūpono no nā wahiʻoluʻolu (Hvac, ʻO ka ho'ōlaʻana i ka meaʻai).
Pehea ka lōʻihi o kahi kila kila kila kila?
ʻO ka ola ola ola mai nā makahiki 10-25. Me nā'ōlelo maʻamau, lubrication makahiki, a me nā koho kūpono kūpono (E.g., 2507 no na kaa), Hiki iā ia ke hoʻonui 30+ makahiki-8x lōʻihi ma mua o nā valves keleawe i nā wahi hoʻoponopono.
Hiki ke hoʻohanaʻia nā val bet ball bet no ka lawelawe hydrogen?
ʻAe-hoʻohana 316ln (nutrogen-hoʻoikaika) Oole 2507 nā mea makemake e pale i ka hydrogen embrittlement.
E hōʻoia i ka hoʻokōʻana me ka iso 19880-3 (Kameka !≤ × 10 ⁻⁸ 10 ⁻⁸ /(s · cm²)) a me ka leakage e hōʻike ana i ka iso 5208 Kakau Vi.
ʻO keʻano nui loa no kahi ssbv sign?
Loaʻa i nā hōʻailona PTFE i kahi kiʻekiʻe kiʻekiʻe o 260 ° C. ʻOi aku ka nui o kēia kumu seal degradation a me ka leakage. No nā mahana 260-500 ° C, E hoʻohana i nā sila kiʻi kiʻi.
Pehea wau e hōʻike ai i kahi kīleʻa kila kila kila?
A5: Hana i kahi API 598 hōʻike hōʻike: E noi 1.1 × hana hoʻoikaika i ka inlet, poloka i ka puka, a me ke ana o ka leakage me kahi kaula bubble.
No iso 5208 Class vi hoʻokō, ʻO Leakage pono ≤0.0001 cm³ / min per mm o ka biometer.
