Hydraulic type row tube bender is simple in structure, reliable which can bend and correct complicated platen with low cost.
自主开发的拉弯式液压成排弯管机具有结构简单、可靠，可弯管屏形状复杂，还可校正管屏、造价低廉等特点。

Through tests, the wall temperature distribution of platen type reheater has been obtained, and the over-temperature of reheater tube being known from the analysis of test results.
通过试验得到屏式再热器的壁温分布，分析试验结果找出超温的再热器管。
