Parameters of JIS G3461 Carbon Steel Pipe. 1. Mechanical Properties. 1. OD refers to outside diameter. 2. The above table is only applicable for heat exchanger carbon steel tubes. The buyer can appoint the upper limit value of tensile strength. The upper limit value of tensile strength is the above shown value plus 120 N/mm 2. LSAW Pipe - COSASTEELLSAW Steel Pipe Features (1) The testing of 100% ultrasonic of the parent metal ensures the tubes internal quality. (2) Because there was no process of unwinding, flattening and alignment, the base material is dented and scratched less. (3) The welding is carried out in a straight line in a horizontal position after the forming is completed.

The paper gives an overview of the theory, practice and application of ultrasonic flaw detection.
Concrete-filled steel pipes have been widely used as piles for supporting marine and civil structures. They provide good bending resistance and can be easily spliced for long depth installations. In addition, they have high strength and ductility and are an economical solution for bridges. However, these piles are usually exposed in water, particularly seawater, and thus the outside corrosion Water and Wastewater Pipe Nondestructive Evaluation and May 19, 2010 · The selection of the inspection method is mainly driven by the pipes size and material. For instance, eddy currents (EC), electromagnetic testing (EMT), and ultrasonic testing (UT) are used in metal pipes. Acoustic emission (AE), impact-echo
