The scope of engineering supervision involves oil and gas processing equipment, skid-mounted equipment, boilers, pressure vessels, pipelines, surface engineering equipment and facilities, tools, instruments and meters in the project.

The operation and maintenance work before the commissioning of oil and gas engineering projects is a critical stage to ensure the smooth and safe operation of the project.

Through the metrological calibration of instruments and meters in marine engineering projects, a complete traceability system for measurement values is established. Through information management methods, comprehensive and timely traceability of assets is achieved to ensure the "accuracy, consistency, traceability, and legality" of measurement value transmission! Potential risks are promptly identied, preventive measures are taken to avoid accidents, and the safety of personnel and property is guaranteed.

Provide customers with an integrated solution for leak detection and monitoring throughout the entire lifecycle of oil and gas engineering projects.

Construction safety monitoring is a crucial link in ensuring the safe and smooth progress of construction projects. Tong'ao Inspection can provide safety monitoring services throughout the construction process of oil and gas engineering projects.

Cathodic protection is one of the effective methods to prevent electrochemical corrosion of metals. By applying a certain cathodic current to the protected steel pipeline, the corrosion process can be effectively slowed down and inhibited. Cathodic protection can be divided into the sacricial anode method and the impressed current method. Both methods can inhibit corrosion, thereby keeping metal structures in a good state of protection, extending their service life, and preventing accidents.
