Stress Relief Design for Pressure Equipments at Stress Corrosion Condition
Abstract：Based on the conditions of generating stress-corrosion-crack,the concept of stress relief design for pressure equipments such as boiler and pressure vessel was brought forward.Its three aspects,operation processing,structure and heat treatment design for stress relief,were expatiated accordingly.And aiming at the caustic embrittlement happened in some smoke tubes fracture of a oil(gas)-fired boiler of LHS series and field manufacturing for pressure vessel,a new kind of boiler structure and the technique of field manufacturing for stress relief were introduced respectively.
