ASTM A53 Gr.B pajp ta 'l-azzar tal-karbonju b'temperatura għolja-huwa tubi ta'-prestazzjoni għolja manifatturati f'konformità ma 'standards ASTM A53/A53M, iddisinjati speċifikament għal applikazzjonijiet ta' trasport ta 'fluwidu ta' -temperatura għolja. Il-kompożizzjoni kimika tagħha hija fformulata b'mod metikoluż b'kontenut ta 'karbonju Inqas minn jew ugwali għal 0.30%, kontenut ta' manganiż li jvarja minn 0.29% sa 1.06%, kontenut ta 'fosfru u kubrit kull wieħed Inqas minn jew ugwali għal 0.035%, u kontenut ta' silikon akbar minn jew ugwali għal 0.10%. Dan id-disinn tal-kompożizzjoni jagħti lill-pajp ta 'l-azzar bi proprjetajiet mekkaniċi eċċellenti: saħħa tat-tensjoni Akbar minn jew ugwali għal 415 MPa, saħħa ta' rendiment akbar minn jew ugwali għal 240 MPa, u elongazzjoni li tissodisfa r-rekwiżiti standard, tiżgura l-istabbiltà strutturali anke taħt-temperatura għolja u kundizzjonijiet ta 'tħaddim ta' pressjoni għolja-.
