BAIJIAN - Third party testing organization
Steel pipe welding quality and component connection inspection
Appearance defects of steel pipe welds、 detection methods and quality evaluation indicators should be determined in accordance with the current "Code for Acceptance of Construction Quality of Steel Structures"
When the steel pipe is self rolled by the construction unit、 the quality evaluation index of the weld groove should be determined in accordance with the "Design and Construction Specification for Steel Pipe Concrete Structures"
Concrete strength and defect detection in steel pipes
The compressive strength of concrete in steel pipes can be tested using the ultrasonic method or the method of drilling concrete core samples.
The compressive strength correction test specimens shall be concrete cubes with a side length of 150mm and the same conditions、 or concrete core samples with a diameter of 100mm (aspect ratio 1:1) drilled from the structural component testing area. The number of test blocks or specimens shall not be less than 6; The correction amount or correction coefficient of the corresponding sample can be obtained、 and one-to-one corresponding correction coefficient can also be used
Defects in concrete in steel pipes can be detected using ultrasonic method、 and the detection operation can be carried out in accordance with the provisions of the "Technical Specification for Ultrasonic Testing of Concrete Defects"
