Service Advantages

In the field of non-destructive testing of metallic materials, our organization provides full-process, high-quality testing services for clients across various industries, leveraging a comprehensive qualification system, a professional technical team, and an efficient service model. Our core strengths can be summarized in the following five dimensions, fully meeting the needs of equipment safe operation and enterprise production:

I. Comprehensive Qualification System:

We have obtained a Class B Testing Institution Certificate assessed by the China Special Equipment Inspection Association, and a Special Equipment Class A B1 Inspection Institution Approval Certificate issued by the Shaanxi Provincial Administration for Market Regulation. We possess NDT capabilities including RT (including DR), UT, MT, PT, TOFD, PAUT, and ECT.

II. Professional Technical Team:

Our team brings together many industry elites deeply engaged in the field of special equipment inspection and testing, including several senior special equipment inspection experts and young technical leaders. We have dozens of special equipment inspectors and over one hundred NDT personnel, relying on profound professional knowledge and practical experience to provide clients with an exceptional service experience.

III. Advanced Equipment and Methods:

We are equipped with internationally leading testing equipment, totaling over 280 sets, including X-ray flaw detectors, pipe crawlers, digital ultrasonic flaw detectors, phased array ultrasonic flaw detectors, TOFD ultrasonic flaw detectors, DR digital radiography detectors, eddy current detectors, spectrometers, buried pipeline coating detection systems (PCMX), underground pipeline locators (RD8200), close-interval potential (CIPS) survey systems, direct current voltage gradient (DCVG) testing systems, and electronically controlled high-definition endoscopes.

IV. Broad Business Coverage:

Our projects span petrochemical refining, chemical plant installations, coal chemical projects (coal-to-liquid, coal-to-gas, coal-to-methanol, etc.), long-distance transmission pipelines and surface gathering projects (oil and gas transmission), urban pipeline network projects (heating networks, natural gas networks), gas filling station/LPG station pipeline projects, storage projects (spherical tanks, storage tanks, cryogenic tanks), power plant projects, food/pharmaceutical/cement/glass processing/fertilizer/gas manufacturing/military manufacturing plant projects, as well as hotel/hospital projects with self-provided boilers.

The scope of work for the above projects includes third-party or fourth-party NDT and periodic inspection of pressure vessels/pipelines for new construction, repair and maintenance, and in-service inspections. Based on client needs, we also conduct specialized inspections and tests on metallic materials, including spectroscopic analysis (chemical element analysis), hardness testing, metallographic examination, wall thickness measurement, mechanical property testing, and physical property testing. Additionally, we perform annual inspections of pressure pipelines/pressure vessels within the scope of our special equipment inspection authorization, as well as commissioned inspections for equipment exceeding their design service life.

V. Extensive Geographic Coverage:

Our company's service projects cover multiple provinces and autonomous regions, including Shaanxi, Gansu, Ningxia, Inner Mongolia, and Xinjiang.
