The reason of magnetic deflective blow when highpressurevapor pipe is magnetized and welded is analyzed. A new simple demagnetizing weld is introduced.
分析了高压蒸汽管线带磁及焊接时产生磁偏吹的原因，介绍了简易消磁焊接新方法。

Above the critical temperature and under highpressure the vapor may become as dens and as incompressible as the liquid at lower temperature.
在临界温度以上和高压下，蒸汽密度可能变得象在低温下液体那样稠密且不可压缩。

The existing density compensator model does not fit high temperature and pressure saturated vapor, the density compensator precision is low and causes big error in saturated vapor measurement.
