Quality Precision – Carridea’s Pursuit of Perfection in Every Detail

Precision is the core demand of the precision steel pipe industry, and quality is the lifeline of an enterprise. Jiangyin Carridea, as a national high-tech small and medium-sized enterprise, has been deeply engaged in the research and manufacturing of cold-drawn tube and honed tube for 17 years, adhering to the production concept of "high quality, large scale, high standards and exquisite craftsmanship", and interpreting the pursuit of perfection with millimeter-level precision and strict quality control.

To achieve the ultimate precision of products, Carridea has invested heavily in introducing advanced production equipment and established an intelligent production system. The company is equipped with 12-meter annealing furnaces, CNC honing units, boring and rolling integrated units, grinding machines and other professional equipment, which technically ensures the accuracy of product dimensions, with a dimensional deviation of only ±0.05mm. Through the digital production system, the whole process from raw material processing to logistics distribution is controllable, and the production efficiency and product precision are greatly improved.

Carridea has created a unique "three core processes + 20 quality inspection procedures" production model to solve the industry’s common problems such as cylinder tube leakage and cylinder installation jamming. The company strictly controls the straightness of products within 0.25-0.3mm/m, the inner hole size accuracy reaches H7-H9 level, and the surface finish is Ra0.2-0.4μm, which are far higher than the industry average level. For example, the special pipe for mine hydraulic support cylinders customized by the company for Sany Heavy Industry has a service life twice that of conventional products, successfully solving the wear and pressure resistance problems under extreme working conditions.

Quality control runs through every link of Carridea’s production. The company has set up a professional quality inspection team with more than 50 technical personnel, implementing "inspection upon raw material entry, random inspection during cold drawing, full inspection during production and final inspection before delivery". Special inner hole straightness measuring instruments are used for precise detection, and 30-odd quality inspection procedures are carried out to ensure that every product delivered to customers meets the quality standards. The company has passed ISO9001

quality management system, environmental management system and occupational health and safety management system certification, building a comprehensive compliance production barrier.

Carridea adheres to the concept of "zero defect" and regards every detail in the production process as the key to ensuring product quality. From the debugging of equipment to the operation of workers, from the control of processing temperature to the inspection of finished products, every link is strictly standardized and controlled. The company also provides third-party inspection reports for products, so that the quality of each pipe can be "seen and measured", which fully reflects Carridea’s pursuit of product quality and responsibility to customers.

With its strict quality control and excellent product precision, Carridea has won wide recognition from the market and customers. The company’s products are widely used in hydraulic systems, construction machinery, mine machinery, shipbuilding and other fields, and have been highly praised by customers for their stable performance and high precision. In the future, Carridea will continue to take quality as the core, constantly improve the quality management system, innovate production processes, and provide the market with more precise and reliable precision steel pipe products.
