Alloy piip is in soarte fana106 koalstof naadleaze stielen piip.De prestaasjes binne folle heger as dy fan gewoane naadleaze stielen piip.Want ditstielen piipbefettet mear Cr, syn hege temperatuer ferset, lege temperatuer ferset en corrosie ferset binne oare.Sewed stielen buizen kinne net oerien, dusnaadleaze alloy stielen boiler piipwurde in soad brûkt yn petroleum, gemyske, elektryske krêft, boiler en oare yndustry.
Benammen standert fanAlloy Steel Pipe:
GB/T8162, GB3087, GB5310, ASME SA210, ASME SA213, DIN17175
Applikaasje: Foar ferwaarming pipen mei lege en medium druk boilers (wurkdruk is oer it generaal net mear as 5.88Mpa, wurkje temperatuer is ûnder 450 ° C);brûkt yn hege druk boilers (wurk druk is oer it algemien boppe 9.8Mpa, wurk temperatuer is tusken 450 ° C en 650 ° C) Heating oerflak piip, economizer, superheater, reheater, petrochemyske yndustriële piip, ensfh
