The customer in Caracas, Venezuela is a well-known local petroleum equipment parts manufacturer, mainly engaged in supporting petroleum mining equipment, which is in line with the country's characteristics of rich petroleum resources and the petroleum industry as the pillar of the national economy. The 400 cartridge heaters purchased this time are used for the heating of petroleum mining molds. The customer's core needs are that the products are oil-resistant, high-temperature resistant and structurally stable, and can adapt to the high-temperature, high-oil-pollution and multi-vibration working conditions of petroleum mining sites. Combined with customer needs, we selected SS316 stainless steel tubes, which have excellent oil resistance, high temperature resistance and corrosion resistance, can work stably in a high-temperature environment of 240℃, adapting to the harsh working conditions of petroleum mining; the pipe diameter is 10mm, the pipe length is 190mm, matched with high-temperature silicone wire resistant to 250℃, and shockproof terminals to improve the product's shock resistance, avoiding poor circuit contact caused by vibration at the mining site; the pipe mouth adopts a sealed design to effectively prevent oil pollution and sediment from seeping into the tube body and extend the service life of the product. The interior is filled with high-purity high-temperature resistant magnesium oxide powder, matched with Ni80Cr20 resistance wire, and adopts high-pressure vibration powder filling technology to ensure that the powder is tightly filled without gaps, even heating, avoiding local overheating damaging petroleum mining molds and ensuring mining efficiency. In the production process, we strictly followed Venezuela's petroleum industry standards, launched a special oil-resistant production line, and each process was subjected to oil resistance, high temperature resistance and shock resistance tests. All 400 products are qualified, with a pass rate of 100%. Considering the inconvenience of maintenance at the petroleum mining site, we optimized the product structure to improve product stability and service life, ensuring that the product service life can reach more than 7000 hours. The packaging link adopts oil-proof, shock-proof and waterproof packaging, independent vacuum packaging + double-layer shock-proof and oil-proof cartons + built-in shock-proof foam, 15 pieces per bag, with bilingual labels in Spanish and English pasted on the outside of the carton, clearly marking product specifications, oil resistance grade and quality inspection number. The logistics department has connected with the South American special line logistics in advance, done a good job in shock-proof and oil-proof transportation protection, and it is expected to arrive in Caracas within 6 working days to help customers improve the operational stability of petroleum mining equipment, in line with the needs of the country's petroleum industry development.
