ASTM A672 klassi b60 klass 22 EFW toru kirjeldus
A672GrB60Cl22 on materjaliklassi tähis, mis vastab konkreetsetele rahvusvahelistele standarditele. See tähistus sisaldab palju teavet: "A672" viitab keskmise tugevusega elektrofusioonkeevitatud terastoru standardile, mis on tavaliselt toodetud elektrofusioonkeevitusega, kus terasplaate või -ribasid rullitakse ja keevitatakse kokku. "GrB60" näitab materjali konkreetset sorti ja minimaalse voolavuspiiri väärtust; "Gr" on lühend sõnast "Grade" ja "B60" määrab minimaalse voolavuspiiri ühikutes. "Cl22" tähistab "Class 22", täpsustades toru kuumtöötlemise tingimusi. A672GrB60Cl22 puhul tähendab see üldiselt, et toru läbis pärast keevitamist pingeid-vabandava kuumtöötluse, mis aitab parandada selle mikrostruktuuri ja mehaanilisi omadusi ning vähendada keevitusjääkpingeid.
