Kugulitsa Kutentha kwa Carbon Steel Alloy ASTM A508-98 40mn2/45mn2/27simn/20cr/40cr Seamless Steel Pipe Yopangidwa ku China
Kufotokozera Kwachidule:
Mapaipi achitsulo a 27SiMn amagwiritsidwa ntchito kwambiri m'mafakitale amagalimoto, petroleum, mankhwala ndi zotumiza.27SiMn chitsulo chitoliro chimakhala chokhazikika komanso chokhazikika, ndikukutidwa ndi phosphate mkati ndi kunja.Chitoliro chachitsulo ichi chimagwiritsidwa ntchito makamaka pakuzimitsidwa ndi kupsya mtima popanga zida zopondera zotentha (zigawo zama hydraulic) zomwe zimafuna kulimba kwambiri komanso kukana kuvala, komanso kupondaponda kotentha komwe kumafunikira kulimba kwambiri komanso kukana kuvala.
27SiMn opanda zitsulo chitoliro ali kuuma mkulu, yovuta hardability awiri m'madzi ndi 8 ~ 22mm, machinability wabwino, sing'anga ozizira mapindikidwe plasticity ndi weldability;Kuonjezera apo, kulimba kwa chitoliro chachitsulo sikumachepetsedwa kwambiri panthawi ya chithandizo cha kutentha, koma kumakhala ndi mphamvu zambiri komanso kukana kuvala, makamaka pozimitsa madzi.
Ntchito yathu nthawi zonse imakhala yopatsa makasitomala athu ndi makasitomala zinthu zabwino kwambiri komanso zonyamulika zama digito Zogulitsa Zotentha za Carbon Steel Alloy ASTM A508-98 40mn2/45mn2/27simn/20cr/40cr Seamless Steel Pipe Yopangidwa ku China, Tidzapereka zinthu zabwino ndi ntchito zabwino kwambiri pamitengo yopikisana.Yambani kupindula ndi mautumiki athu onse polumikizana nafe lero.
Ntchito yathu nthawi zonse imakhala yopatsa makasitomala athu ndi makasitomala zinthu zabwino kwambiri komanso zankhanza zam'manja za digitoChina Seamless Steel Pipe ndi Seamless Pipe, Kampani yathu imayang'anira mzimu wa "zatsopano, mgwirizano, ntchito yamagulu ndi kugawana, mayendedwe, kupita patsogolo kwanzeru".Tipatseni mwayi ndipo tidzawonetsa kuthekera kwathu.Ndi chithandizo chanu chokoma mtima, timakhulupirira kuti tikhoza kupanga tsogolo labwino ndi inu pamodzi.
