管道燃气工程由于隐蔽工程多，检查的难度也较大，特别是其质量的好坏并不是

Gas pipeline project due to the hidden works much difficulty checking is also large, especially its quality is not a visual inspection and manual testing can fully judge the general quality of the project can not do the whole supervisory inspection test, it is difficult to find hidden quality defects, therefore, prone to errors of judgment on the quality of the project.

Pipeline gas project because of hidden engineering, the difficulty of inspection is also greater, especially its quality is not the appearance of inspection and manual testing can be fully judged, generally can not do the whole inspection of the quality of the project, it is difficult to find hidden quality defects, therefore, easy to cause the wrong judgment of the quality of the project.

Because there are many concealed works in pipeline gas engineering, the difficulty of inspection is also great, especially the quality is not completely judged by appearance inspection and manual inspection. Generally, the quality inspection of the whole supervision and inspection project cannot be achieved, and it is difficult to find hidden quality defects. Therefore, it is easy to cause the wrong judgment of project quality.
