API SPEC 5CT标准使用中的要点分析

Analysis of Key Points in the Use of API SPEC 5CT Standard

针对API SPEC 5CT标准中PSL1钢管产品要求,采用归纳分类法,从工艺过程方法分类、接箍验收注意问题、两组相似钢级对比、冲击功及加厚油套管拉伸试验几个方面入手,归纳分析了标准使用中需要注意的问题。为标准使用者准确把握产品要求,加深标准理解,解决标准现实使用中存在的问题提供参考。

According to the requirements of PSL1 of API SPEC 5 CT standard（product specification Level 1） to steel pipe products, the problems to be paid attention to in the use of the standard are analyzed from the classification of technological process, the acceptance of collars, the comparison of similar two groups of steel grade, the impact work and the tensile tests of thickened tubing and casing by using classification method, which is helpful for the standard users to accurately grasp the requirements to steel pipe products, deepen the understanding of the standard, and solve the existing problems in the use of standard reality.
