The theASTM A312 UND S30815 253ma Stainless Steel pombiis the yakakwira autenitic stainless simbi alloy inozivikanwa nekupokana kwayo kune yakakwirira-tembiricha audidation, Corrosion, uye yakanakisa manhamba munzvimbo dzakakwirira tembiricha.253mayakagadzirwa chaizvo yekushandira mune zvekushandisa inoda kuti isimbe-tembiricha kugadzikana, kunyanya muvira uye inopisa maindasitiri ekurapa. Kwakanaka kupokana kuti uvharise, Carburization, uye General Oxidation inoita kuti ive nzvimbo yakavimbika yenzvimbo dzakanyanyisa.
Iyi giredhi yesimbi isina kushandiswa inoshandiswa zvakanyanya mune yakakwirira-tembiricha mashandiro eindasitiri uye yakanakira maficha ipo paine simba rakakwirira uye kusimba kwe oxidation zvinokoshesesa.

Production Process: CraftsmansHips yekunyora
Kugadzirwa kwe253ma Stainless Steel PIPESInotevera nzira dzekuratidzira dzazvino kuti dzive nechokwadi chekumusoro uye kusimba:
- Seamless pombi yekugadzira.
- Kutonhora-kushanda maitiro.
- Kupisa kurapwa: Mapipi anodziya ekupisa pakurapa kune chaiyo tembiricha kuti uwedzere midziyo yavo yemuchina uye yakakwirira-tembiricha kuita.
- Kurongedza & kupaza: Mapepa anotorwa kuti abvise chiyero uye mafirimu ehodhi uye akaparadzaniswa kuti ave nechokwadi chekurwisa kudzikama.
