In order to strengthen the quality management of the process, Yangzi Supervision has clarified the focus of quality control in the three stages of pre-event, in-process and post-event control, and guarantees the quality of the project with excellent management.

1. Prior Quality Control

Strengthen qualification examination and material inspection, strictly inspect machinery and tools, carefully review drawings and approval plans, and ensure that construction procedures are in compliance with laws and regulations.

2. In-process quality control

1) Civil construction construction strictly controls the incoming inspection of raw materials, and the acceptance rate of some completed projects is 100%.

A series of propylene compressor reinforcement works and formwork works of the refrigeration and compression unit of the purification unit passed the one-time acceptance inspection

2) Strictly control and check the quality of each key point in the ground pipe quality process.

Check the quality of centralized anti-corrosion and rust removal

3) The on-site installation of large static equipment follows strict implementation procedures and control.
