NDT Branch belongs to T-ALL INSPECTION, started in 2002, NDT Branch provides drilling tool inspection, maintenance and evaluation, oil and gas site inspection, oil drilling and production equipment inspection, petrochemical equipment inspection, surface engineering inspection technology, offshore platform equipment and facilities safety inspection. It is the most competitive and largest oilfield NDT integrated service provider in China. It is the first third-party testing technology service provider in China to enter the international oilfield market and has international competitiveness.

Drilling tool inspection and maintenance and evaluation, is to carry out non-destructive testing and inspection of oil drilling tools and wellhead tools, and conduct graded evaluation of their safety, to provide customers with professional drilling and workover tools testing and evaluation, maintenance, wear-resistant band welding and drilling tool asset management integrated services. Ensure the safe use of drilling tools, prevent failure accidents, effectively eliminate drilling accidents, improve drilling efficiency, reduce drilling costs.

Oil and gas station testing is a non-destructive testing technical service for the construction of new oil and gas station engineering. In service, oil and gas station equipment and pipeline corrosion detection and risk assessment are carried out to effectively assess the quality of oil and gas station equipment and pipelines, prevent oil and gas leakage, poisoning and explosion accidents, prevent accidents, and ensure the safe operation of oil and gas station.

Petrochemical equipment testing is the non-destructive testing and risk assessment of new and in-service petrochemical storage tanks, pressure vessels, devices and pressure pipelines. Detect the internal and surface defects, including incomplete structure, defects and residual stress damage, to ensure the safe operation of petrochemical equipment, improve manufacturing process, improve production efficiency, and extend the service life of equipment.

Non-destructive testing of oil and gas field surface engineering refers to the non-destructive testing of the welding joints of oil and gas field gathering and transportation pipelines and process pipelines in the field station during the construction of oil and gas field surface engineering, and the excavation verification and testing evaluation of in-service pipelines. It is an important means to ensure the quality of oil and gas pipelines, and is of great significance to ensure the quality and safety of ground engineering of oil and gas fields and promote the sustainable development of oil and gas fields.

The safety testing of offshore platform equipment and facilities is the inspection and testing of offshore pressure pipelines, pressure vessels, facility structures, and professional equipment, which is to ensure that offshore professional equipment and facilities have the technical conditions for safe production and operation, and to protect the safety of people's lives and property and prevent water environment pollution.
