The customer in Oslo, Norway is mainly engaged in the R&D and production of marine engineering equipment. The 100 cartridge heaters purchased this time are used for the mold heating of its offshore platform mechanical equipment. The working environment is a marine high-salt and high-humidity environment, with extremely high requirements for product corrosion resistance. The surface of the tube body is treated with a special anti-corrosion coating to effectively isolate the erosion of seawater and salt spray and extend the service life of the product; the interior is filled with high-purity magnesium oxide powder, matched with Ni80Cr20 resistance wire to ensure uniform and stable heating, adapting to the continuous working needs of marine engineering equipment. After production, the quality inspection department focused on corrosion resistance testing, adopting the simulated marine salt spray environment test method, placing the products in a salt spray test chamber for continuous testing for 72 hours. After the test, the products had no rust, no damage, no abnormality in circuit stability, and the corrosion resistance fully met the customer's requirements, with a test pass rate of 100%. At the same time, we have also completed the on-off test, temperature resistance test and appearance inspection, and all products meet the standards. At present, this batch of products has entered the packaging preparation stage, and will be packaged in corrosion-resistant and waterproof packaging, independent vacuum packaging + waterproof cartons + anti-corrosion film, with every 15 pieces packed in a bag. Bilingual labels in Norwegian and English and anti-corrosion marks are pasted on the outside of the carton to facilitate customer identification and use. The logistics department has connected with the Nordic sea freight special line in advance, done a good job in salt spray and waterproof transportation protection, and it is expected to arrive at the Port of Oslo, Norway within 5 working days to help customers improve the
