随着压力容器制造技术水平的提高,球形高压容器已在我国广泛应用。由于球形高压容器制造工艺复杂,并伴有开孔接管的问题,所以容器壳体强度容易削弱,开孔周围局部峰值应力增高。为保证容器的安全运行,在制造过程中加强质量控制极为重要。现将我们的做法介绍如下,仅供参考。一、材质控制我厂制造的带接管高压球形容器是为年产六万吨合成氨氮氢气压缩机配套的。材料为西
With the improvement of pressure vessel manufacturing technology, spherical pressure vessel has been widely used in our country. Due to the complicated manufacturing process of the spherical high-pressure vessel and the problem of open-cell takeover, the strength of the container shell is easily weakened, and the local peak stress around the opening is increased. In order to ensure the safe operation of the container, it is very important to strengthen the quality control in the manufacturing process. Now we introduce the following practices, for reference purposes only. First, the material control I plant with high pressure spherical containers is to take annual output of 60,000 tons of synthetic ammonia nitrogen hydrogen compressor supporting. Material for the West
