化工生产用压力容器壳体,因受到腐蚀和各种应力作用使得壁厚减薄,强度降低。为此,我厂按“压力容器安全监察规程”的有关规定,在停车大检修期间和单台容器停车间隙,对压力容器作定期检测。主要采用沪产CCH-10A型超声波测厚仪对壳体壁厚进行测定。根据测得的最小壁厚校核其强度,并结合其它检测结果决定该容器所需的措施。液氯是一种剧毒易腐蚀物质。我厂七台大型液氯贮罐,使用时间均在十年以上。1983年,对3、4号计
Chemical production pressure vessel shell, due to corrosion and a variety of stress makes the wall thickness thinning, strength reduction. To this end, our factory according to “Pressure Vessel Safety Supervision Regulations ” the relevant provisions of the parking lot during the overhaul and single container parking clearance, pressure vessels for regular testing. The main use of Shanghai CCH-10A ultrasonic thickness gauge shell wall thickness was measured. According to the measured minimum wall thickness to check its strength, combined with other test results to determine the required measures for the container. Liquid chlorine is a highly toxic and corrosive material. I plant seven large liquid chlorine storage tank, the use of time are more than 10 years. 1983, on the 3, 4 meter
