优质钢管是我国的短线产品,增加优质钢管的生产对于发展国民经济和提高企业的经济效益具有重要意义。目前我厂的钢管产量在逐年增加,对产品的质量要求也越来越高。在力学性能试验中最常见的是拉力试验和压扁工艺试验。当钢管产量多、受检量大时,在计算上往往出现困难或花费很多时间,影响检验速度。例如,我们常用到整管拉力试样的横截面积(F_0)数值及压扁工 High-quality steel pipe is our country’s short-term products, increase the production of high-quality steel pipe for the development of national economy and improve the economic efficiency of enterprises of great significance. At present, I plant steel pipe production increased year by year, the product quality requirements are getting higher and higher. The most common mechanical properties test is the tensile test and flattening process test. When the steel pipe production, large amount of test, the calculation is often difficult or spend a lot of time, affect the test speed. For example, we commonly used to the whole pipe tensile specimen cross-sectional area (F_0) value and crush
