Recently, Mtsco's 30 tons Alloy 625 heat exchanger tube production has come to an end, and has entered the sampling inspection stage. This order is of pioneering significance for Mtsco to export nickel alloy products. Based on the strategic cooperation with European customers and the assurance of the best quality, we have online connection with the third party inspection at home and abroad to witness the accuracy of the inspection.

The day before the test, we took a sample from each batch of finished products with the same heat number, marked them and waited for inspection. The whole process of sampling was recorded by camera to ensure the fairness of the test results.

The inspection items include mechanical property test, chemical composition analysis, dimension test, PMI test, hydrostatic test, etc. In addition, we also sent the samples to the third party Laboratory for 120 hours intergranular corrosion test.

The two-day third-party inspection has been completed successfully. Under the witness of Lloyd's at home and abroad, all the inspection results are in line with the standards and recorded by camera. For a long time, the quality of Chinese nickel alloy products has been questioned in European and American markets. In recent years, through the efforts of Mtsco and ERAUM, they have continuously improved product quality and developed new products, and gradually gained the trust of more and more customers.

Mtsco is currently able to provide pipe, coiled tubing, fittings, flanges, plates and strips made of nickel alloy 600/601/625/825/C276/C22/400..... ERAUM products have been used in petroleum, aerospace, military and other fields.

The whole process of inspection proves the quality assurance of Mtsco. Made in China has become the synonym of high cost performance. Give us a chance to cooperate, we will create higher value for you.

The following is the details of the third-party inspection and scene picture sharing, let's take a look at the quality of Mtsco！

Sampling. In the early stage, take a section of sample from the pipe with the same heat number, mark and record it

Metal tensile test is one of the simple mechanical property tests. Through tensile test, the most basic mechanical property indexes in the process of elastic deformation, plastic deformation and fracture can be measured, such as positive elastic modulus E and yield strength σ 2, yield point σ s. Tensile strength σ b. Elongation after fracture δ And the contraction rate after fracture φ And so on. The index of tensile property is the basic property of material and the main basis of engineering design.

Hardness test is one of the most important indexes for testing material properties, and it is also one of the fastest and most economical test methods. The reason why hardness test is a common method of mechanical property test is that hardness test can reflect the differences in chemical composition, microstructure and treatment process of materials.

Chemical composition analysis can accurately analyze the metal elements and non-metal elements in the sample, and intuitively see the composition of each chemical component of the finished product

Dimension inspection includes outer diameter, wall thickness, length, straightness and port inspection

Portable spectrometer is used for classification, grade identification and composition analysis of metal and alloy materials on site.

Hydraulic test is widely used in daily life, such as hydraulic flaw detection, pressure and burst test of small valves, pressure vessels, various metal and non-metal pipes.

The two-day third-party inspection has been completed successfully. Under the witness of Lloyd's at home and abroad, all the inspection results are in line with the standards and recorded by camera. After a while, intergranular corrosion test results will come out, remember to pay attention to my latest posts!
