随着我国对外开放的不断扩大,进口压力容器用钢的使用也越来越普遍,这就给压力容器制造厂的钢材验收和使用带来了一些新问题。有些单位在使用进口钢材时仅仅把其强度指标与国内钢材进行比较,采用了强度对等原则;有些单位在对进口钢材复验时,仍采用国内的试验方法;有些单位甚至在无国外标准的情况下,按国内钢材相应的性能对进口钢材进行验收。这种对进口钢材的验收和使用的方法是不恰当的。
With the continuous expansion of China’s opening up, the use of imported pressure vessel steel is also becoming more and more common, which brings some new problems for acceptance and use of steel in pressure vessel manufacturers. Some units use imported steel only to compare their strength indicators with those of domestic steel products and adopt the principle of strength equivalence. Some units still adopt domestic test methods when re-inspection of imported steel products. Some units even use non-foreign standards Case, according to the corresponding performance of domestic steel imported steel acceptance. This method of acceptance and use of imported steel is not appropriate.
