Prediction of the Residual Creep Life of SA335-P22 Steel Main Steam Pipelines

Round 1

Reviewer 1 Report

In this study, the 9 comprehensive properties of a P22 high-temperature steam pipeline with moderate spheroidization were 10 evaluated after more than 11,700 hours of operation through a series of chemical, physical, and chemical 11 tests, utilizing a creep test.  This is an interesting study, and is of great significance to the engineering field. I recommend this paper can be accpeted after addressing minior issues:

1  The language use of this study can be improved to avoid some spelling errors.

2 The introduction can be richened to include the gap between this study and previous ones. The related studies on this topic should be discussed clearly. The innovitation of this study should be clarified. How this work is dfferent from others.

3 The conclusion of the present work should include the limitations and future work of this study. This is imporant for readers.

4 The resolution of pictures in the mansucirpt should be improved.

Reviewer 2 Report

This manuscript covers an important issue for the oil and gas industry. The comprehensive properties of a P22 high-temperature steam pipeline with moderate spheroidization were evaluated after more than 11,700 hours of operation through a series of chemical, physical, and chemical tests, utilizing a creep test. It is worthy of publication but requires substantial revisions. Following questions are listed for the authors' consideration.

1. Although the English is understandable, there are a great number of grammatical errors. The manuscript needs to be thoroughly checked by a native English speaker and corrections made.

2. In this paper, the properties of P22 material are studied based on the test method. Besides the influence of temperature on the strength and parameter modulus, any other factors are considered in the life prediction?

3. Please confirm whether the values of elastic modulus at room temperature and high temperature are correct.

 

4. How to evaluate and guarantee the accuracy of residual life prediction model？
