DIN 1.4438 EFW Tube Inowanikwa Maererano neInternational Standards uye Zvinotsanangurwa Stainless simbi capillary coiled tubing
DIN 1.4438 EFW Tube Inowanikwa Maererano Nenyika Dzepasi Pose uye Zvinotsanangurwa
Sezvinoita alloy 316, kemikari yesimbi yakaderera kabhoni ine chromium, nickel, uye molybdenum.An austenitic alloy ye300 series, iyo 317L Stainless Steel Seamless Tubes inoonekwa seshanduko pamusoro pegiredhi 316. Zviri mukati molybdenum mumakemikari alloy iyi yakakwirira kudarika 3%.Iyi yakagadziridzwa molybdenum giredhi alloy ine akati wandei akakosha maitiro.Semuyenzaniso, iyo WERKSTOFF NR.1.4438 Heat exchanger Tube inoratidza kuramba kwegomba uye kukoromoka kwegomba zvichienzaniswa nealloy 316.
