Abstract

Abstract: The reasons leading to abnormal operation of hot reheater steam pipes in No.1 supercritical unit of Ruijin Power Plant of China Huaneng Group during trial operation were analyzed, and the pipe stress was calculated. Based on above analysis, the optimal adjustment scheme of the supports and hangers of the pipe was put forward.After implementation of the scheme, the pipe stress is equalized, the supports and hangers work well, and the requirement of longterm safety operation condition is satisfied.

Key words: pipe, supports and hangers, abnormal operation, reason analysis, stress calculation, optimal adjustment
