Inquire

In order to make the pipeline production more professional, we usually carry out some tests, so what is the eddy current flaw detection test?

Eddy-current testing (also commonly seen as eddy current testing and ECT) is one of many electromagnetic testing methods used in nondestructive testing (NDT) making use of electromagnetic induction to detect and characterize surface and sub-surface flaws in conductive materials.

 

Common applications of eddy current detection are pipeline checks in heat exchangers and condensers.

 

ECT uses electromagnetic induction to identify defects in the pipeline. Place the probe into the tube and pass through the tube. The eddy currents are generated by the electromagnetic coil in the probe and are monitored simultaneously by measuring the probe electrical impedance.

Eddy current tube detection is a non-destructive method for finding pipe defects that is effective for many different pipe materials and can detect defects that may cause greater problems for heat exchangers and condensers.

Several types of defects in the pipe can be detected using an eddy current detection method:  

1.Internal diameter (ID) and outer diameter (OD) pitting

2.cracking  

3.Wear (from supporting structures, other pipes and loose parts)

4. Outer diameter and inner diameter erosion

Every time the finishing tube is rolled, it must go through the process of solution treatment. Ta ensure that the performance of the steel pipe meets the technical requirements. and to provide guarantee for the post-process processing or use. Bright solution treatment process of ultra-long seamless steel pipe has always been a difficulty in the industry.

Traditional electric furnace equipment is large,covers a large area, has high energy consumption and large gas consumption, so it is difficult for realize bright solution process. After years of hard work and innovative development, the use of current advanced induction heating technology and DSP power supply. Precision control of heating temperature to ensure that the temperature is controlled within t2C,to solve the technical problem of inaccurate induction heating temperature control. The heated steel pipe is cooled by "heat conduction"in a special closed cooling tunnel, which greatly reduces the gas consumption and is more environmentally friendly.
