Non-destructive testing of steel structure welds

Non-destructive testing of steel structure engineering has been widely used in various industries today. Welding seam, as one of the most extensive basic ways to connect steel structural members, to achieve the core of the steel structure large span, beautiful appearance and superior performance has become an important link to ensure the quality of steel structure engineering. Its good quality is directly related to the safety of the entire steel structure project.

Billboard detection

Billboard safety inspection, landing billboards, anti-aircraft billboards, single-post billboards, wall billboards, roof billboard detection, highway billboard detection, highway billboard detection, toll booth billboards and other fields.

Boiler non-destructive testing

Boiler non-destructive testing occupies a very important position in boiler inspection. It can detect various defects on the surface and inside of boiler components and their welded joints. Under normal circumstances, these defects are difficult or undetectable by conventional inspection methods. Commonly used nondestructive testing methods include radiographic testing, ultrasonic testing, magnetic particle testing, and penetration testing. Some unconventional detection methods such as acoustic emission detection and eddy current.

Non-destructive testing of special equipment

Special equipment testing includes: refers to the life-threatening, dangerous boilers, pressure vessels (including gas cylinders, the same below), pressure pipes, lifting machinery, large-scale amusement facilities. Among them, boilers, pressure vessels (including gas cylinders) and pressure pipes are pressure-bearing special equipment; hoisting machinery and large-scale amusement facilities are electromechanical special equipment.

Ship non-destructive testing

Non-destructive testing of hull and cabin, non-destructive testing of rudder and propeller, non-destructive testing of internal pipelines, non-destructive testing of marine products and thickness measurement of hull.

Non-destructive testing and thickness measurement of forging castings

Non-destructive testing and thickness measurement of castings and forgings, including plates, bars, pipes, bolts, screws, etc.

(1) The quality inspection of the outer surface of the pipe material of the pressure pipeline inspection.

(2) Inspection of the surface and internal defects of important butt welds in pressure pipeline inspection.

(3) Inspection of the surface and internal defects of important fillet welds in pressure pipelines.

(4) Pressure pipeline inspection. Inspection of the welded joint surface and internal defects of important socket welding and bridging tee branch pipes.

(5) Pressure pipeline inspection Surface defects inspection after pipe bending.

(6) Bevel detection of welded joints of pressure pipeline testing materials with large tendency to quench.

(7) Testing of pressure pipelines with non-austenitic stainless steel pipe grooves whose design temperature is lower than or equal to minus 29 degrees Celsius.

(8) Pressure pipeline inspection. Welding seam of double-sided weldments is required to be cleaned after root cleaning.

(9) Pressure pipeline inspection When oxyacetylene flame is used to cut welding fixtures on alloy pipes that have a tendency to harden, the defects of the repaired parts are detected.
