ABOUT US

Longkou Truck Oil Pipe Co., Ltd. is located in the beautiful and rich Jiaodong Peninsula-Longkou City, Shandong Province. It is located on the south bank of Bohai Bay, facing Yantai in the east, Qingdao in the south, and facing Dalian, Tianjin, and Qinhuangdao across the sea. Parts industry processing base.

The company is mainly committed to the development and production of fuel systems, lubrication systems, and cooling system accessories such as automobiles, construction machinery, and marine generator sets. Several series of products and mature production and processing technology systems have been formed, such as stamping, welding, bending, tightening and machining of high-pressure oil pipe assembly, low-pressure metal oil pipe assembly, low-pressure non-metallic oil pipe assembly, oil gauge pipe assembly and filter collector pipe assembly, with an annual output of more than 9000 million pieces of various oil pipe accessories, with an output value of 0.16 billion.

As an enterprise with large production scale, complete variety, high technical level, advanced equipment and high market share in the domestic oil pipe industry, the company has always adhered to the road of technological innovation. in the first batch of domestic enterprises to adopt new materials, new technologies and new processes to manufacture products in strict accordance with international standards. Since its establishment in 1989, in the course of more than 20 years of development, with advanced technology, modern equipment, strict management and good reputation, to provide our customers with high-quality products and services, won the support and recognition of all sectors of society, so that the company continues to grow and develop.

The company now covers an area of 100000 square meters, construction area of 54000 square meters. With fixed assets of 0.14 billion yuan and working capital of 52.8 million yuan, it has laid a solid foundation for the company's subsequent development. In order to meet the needs of the rapid development of the automobile industry, the company has introduced more than 120 sets of advanced production equipment and testing equipment from all over the world. Among them, "PS1149" inner surface hardening equipment was imported from Germany. "ITP" three-coordinate measuring instrument was imported from Britain. Fenbao imported automatic pipe fitting crimping machine from Finland. Nut spot welding machine was imported from Panasonic of Japan. We have successively purchased more than 60 "EF30-1, EF30-3 and EF50-1" end-finishing machines and "CNC18-50" full-automatic pipe benders with flexible steel pipe diameters ranging from 4mm to 65mm produced by Taiwan technology; purchase special equipment for cleaning, drying and oiling the inner and outer surfaces of the oil pipe assembly and mesh belt type gas protection continuous brazing furnace from Shanghai; Purchase automatic gas seal detection equipment for pipelines, reducing the risk of traditional manual gas seal detection; The company's 100000-class dust-free purification workshop was completed and put into use in 2013.

The high-pressure oil pipe assembly produced by the company is made of advanced high-pressure seamless steel pipe Q-grade pipe imported from Thyssenknuber of Germany, which can withstand pressure of 100-250Mpa and is made of st52.4, DSG1600, DSG1800 and CRG890, which are respectively adapted to different spray pressure resistance requirements of Euro III (III) to Euro V (V) engines on high-pressure oil pipes. The high-pressure seamless steel pipe has narrow tolerance band of inner and smooth inner and inner and inner surface, the fatigue resistance is high and the pressure drop in the pipe is small, which is beneficial to the pressure wave transmission of the fuel pipe. So that the flow to each cylinder of the engine has a small dispersion, the oil volume is uniform, and the consistency is good, which effectively improves the stability of the engine and helps the emission indicators to meet the standards.

The company's existing 100000-level dust-free purification workshop and special internal and external surface cleaning, drying and oiling automatic assembly lines ensure the cleanliness requirements of the inner cavity of the oil pipe. The use of full-automatic pipe bender greatly improves the pipe bending efficiency and product quality. Each pipe component is corrected one by one on the special inspection tool simulating the actual assembly of the engine, thus ensuring the stability and consistency of the product pipe type; all DSG1600, DSG1800 and CRG890 pipes imported from Germany shall be subjected to eddy current flaw detection one by one, thus preventing steel pipe raw materials with quality defects from flowing into the production process and ensuring the stability of pipe quality. By extruding and hardening the inner surface of the high-pressure oil pipe assembly, the pressure bearing capacity of the high-pressure oil pipe assembly is increased by 30% ~ 50%, and the fatigue strength is increased by 5~10 times. Advanced equipment and technology ensure the quality of the company's products, and fully meet the technical indicators of the high-pressure oil pipe assembly for Euro III and Euro V models, so that the company has always been in a leading position in the industry.

The company has a professional physical and chemical laboratory and measuring room, which is carried out by professionally trained experimenters. The detectable items include: metallographic, mechanical properties, chemical composition, corrosion resistance, aging resistance, pressure resistance, cleanliness, etc. The measurement room has obtained the second-level measurement qualification confirmation certificate issued by the State Bureau of Quality and Technical Supervision, which ensures the credibility of the quality inspection of raw materials and finished products.

The company passed the ISO9000 quality system certification in 1999; passed the QS9000 quality system certification in 2002; passed the ISO/TS16949 quality system certification in the same industry in 2007; passed the type approval of marine diesel engine high-pressure oil pipe in 2012, established and improved The quality assurance system has standardized the management of the enterprise, expanded the popularity of the enterprise, and won the favor of customers. We are actively preparing to apply for ISO14001 environmental management system and OHSAS18000 occupational health and safety management system to make the quality system of the enterprise more perfect.
