China OEM China High Pressure Seamless Carbon Steel Pipe for Liquid Transportation
Mwachidule
Timayesetsa kuchita bwino, kuchitira makasitomala makasitomala", tikuyembekeza kukhala gulu logwira ntchito bwino kwambiri komanso loyang'anira antchito, ogulitsa ndi ogula, timazindikira kugawana kwamitengo komanso kutsatsa kosalekeza kwa High Pressure Seamless Carbon Steel Pipe for Liquid Transportation, Timalandira ndi mtima wonse ogula onse. padziko lonse lapansi bwerani ku malo athu opangira zinthu ndikukhala ndi mgwirizano wopambana ndi ife. Kuphatikiza apo, timathandizidwa ndi akatswiri odziwa zambiri komanso odziwa zambiri, omwe ali ndi luso lambiri pantchito yawo yolumikizana zina kuti tipatse makasitomala athu zinthu zosiyanasiyana ndi mayankho.
Kwa mapaipi amadzimadzi, kuphatikiza muyeso waku America, miyezo yambiri yaku Japan imagwiritsidwa ntchito padziko lapansi. Pakati pawo, JIS G3454 STPG370 ndi zinthu zomwe zimagwiritsidwa ntchito kwambiri mu mapaipi amadzimadzi aku Japan. Zofunikira pakupanga mankhwala ndi: C: 0.25%max, Si: 0.35%max, Mn: 0.3% ~ 0.9%, P: 0.04%max, S: 0.04%max; katundu wamakina ayenera kukhala: mphamvu zamakokedwe: 370Mpa min, zokolola mphamvu: 215Mpa min, elongation: 30%. Zofanana kwambiri ndi GB / T8163 10 #, miyeso iwiriyi imafuna kuyesa kofanana (kuthamanga kwa hydraulic ndi kuyesa kosawononga, kuyesa kwamoto), kotero kuti ziwirizo zikhoza kulowetsedwa m'malo mwa wina ndi mzake.
Kugwiritsa ntchito
Amagwiritsidwa Ntchito Kwambiri Kupanga Zitsulo Za Carbon Structural, Alloy Structural Steel ndi makina amakina.
