In order to meet constant expansion of business in long distance pipeline and pipe installation and pipeline plugging, our company decided to apply for GA1 Grade b, GC1 level and pipeline plugging first class pressure pipe qualification, so as to help our company obtain further development in the field of pressure piping.

In November 1, 2012, oil and gas pressure piping installation permit assessment team of experts came to our company for assessment. The expert group spent three days conducting in-depth understanding and assessment of multiple aspects of our company's equipment archive records, project site and our company's program files. They gave a high evaluation to our company forensics work.

Forensic work has been completed now and the follow-up work also has been gradually spread, we still hope the relevant department colleagues work closely, so as to smoothly pass the evaluation center certification audit.
