检验装备是开展特种设备检验工作的基础之一,是否配备了必要的检验装备是各个特检机构开展检验工作的基本条件,所以装备管理工作是非常重要的一项工作。科学、高效的装备管理工作是对检验工作的强有力支持,也是检验工作质量的保证。在此笔者就中小型特检机构装备管理工作的一些基本问题进行一下探讨。 1 装备的选购 1.1 超声波测厚仪对于配备到每一个检验员的超声波测厚仪宜选用国产的成熟产品,分度值宜为0.1mm,不确定度不高于(0.1+1%)mm;一般应配备2个探头,一个为常规探头,一个为小径管专用探头;每一特检机构应配备至少1台带有高温探头并配有相应高温耦合剂的测厚仪及1台分度值为0.01mm、不确定度为0.01mm的测厚仪。对于大多数情况下的测厚工作,国产测厚仪能够完全胜任,而国产测厚仪的价格只有进口测厚仪的1/5或更少;在大多数测厚工作中,0.1mm的分度值及(0.1+1%)mm的不确定度已经完全能够满足需要,不需要盲目追求高分度值、高不确
Inspection equipment is one of the foundations for the inspection of special equipment. Whether it is equipped with the necessary inspection equipment is the basic condition for the inspection carried out by various inspection agencies. Therefore, the management of equipment is a very important task. Scientific and efficient equipment management is a strong support for inspection work, but also to ensure the quality of work. In this author on the small and medium-sized special inspection agencies and equipment management of some of the basic issues to explore. 1 Optional equipment 1.1 Ultrasonic Thickness Gauge For each equipped with an ultrasonic thickness gauge inspectors should choose the domestic mature products, the dividing value should be 0.1mm, the uncertainty is not higher than (0.1 + 1%) mm ; Generally should be equipped with two probes, one for the conventional probe, one for the small diameter tube probe; each special inspection agencies should be equipped with at least one with a high temperature probe and with the corresponding high temperature couplant and a thickness gauge Thickness gauge with a value of 0.01 mm and an uncertainty of 0.01 mm. For most of the thickness measurement work, the domestic thickness gauge can be fully competent, and the price of domestic thickness gauge is only imported 1/5 or less thickness gauge; in most of the thickness measurement work, 0.1mm points Degree and (0.1 + 1%) mm of uncertainty has been fully able to meet the need, do not blindly pursue the high degree of value, high uncertainty
