GB/T244-2020金屬材料管彎曲試驗方法2020.12.01實施，替代GB/T244-2008。GB/T244-2020標准適用于測定外徑不大于65mm的圓形橫截面金屬管的全截面彎曲塑性變形能力。標准規定了金屬管彎曲試驗方法的試驗原理、試驗設備、試樣、試驗程序和試驗報告。
GB/T244-2020標准修改內容：將管壁厚度符號由‘a’修改爲‘t’，並修改了表1中管壁厚度符號的注；將全文‘彎心’修改爲‘彎模’； 增加了特殊要求的試樣可參照附錄A進行彎曲試驗；將‘對要求在控制條件下進行的試驗’修改爲‘對溫度要求嚴格的試驗’；將‘焊接管’修改爲‘直縫焊管’；增加了資料性附錄‘專用彎管試驗機及試驗方法’；修改采用ISO 8491金屬材料管全截面彎曲試驗；
65mm金屬材料管彎曲試驗機，實現金屬材料管0°～90°任意角度彎曲試驗，金屬材料管彎曲角度實時顯示，HRJ彎曲試驗一鍵操控。HRJ滾轉式彎曲試驗裝置，HRJ包覆式鋼管彎曲溝槽，HRJ滾轉式鋼管溝槽支撐。測定外徑≤65mm圓形橫截面金屬管全截面彎曲塑性變形能力。將不帶填充物的管試樣彎曲到規定角度，觀測鋼管是否産生裂紋、裂縫、裂口或離層。
