Advanced Seamless Steel Pipe Manufacturing Facilities

Our factory is equipped with advanced seamless steel pipe manufacturing facilities to ensure high precision and stable product quality. The main production equipment includes cold rolling machines and cold drawing machines, which enable accurate dimensional control and excellent surface quality during the pipe manufacturing process.

Cold Rolling Machine

Cold Drawing Machine

In addition to core rolling and drawing equipment, the production line is supported by specialized workshops such as precision polishing, solution annealing, and straightening workshops. These facilities allow us to perform processes including cold expansion, cold drawing, and pipe straightening to achieve high mechanical performance and consistent pipe geometry.

Our plant also features pickling lines, natural gas heat treatment furnaces, and dedicated cold drawing workshops. Through these integrated processing facilities, we can ensure reliable material properties, improved corrosion resistance, and stable performance for a wide range of seamless steel pipe applications.

Seamless Steel Pipe Inspections & Quality Tests

At Haomei Aluminum, we specialize in the production and supply of high-quality seamless steel pipes, dedicated to providing safe and reliable products for customers worldwide. To ensure that every pipe meets strict standards, we have established a comprehensive quality control system and a modern testing workshop.

Our Core Inspection Methods

• Ultrasonic Testing (UT): Accurately detects internal defects in steel pipes to ensure structural integrity.
• Chemical Analysis: Strictly monitors material composition to guarantee consistent pipe performance.
• Metallographic Analysis: Examines the microstructure of steel to evaluate strength and durability.
• Tensile Testing: Verifies the tensile strength and elongation of steel pipes.
• Internal Surface Inspection: Ensures the inner surface of pipes is smooth and defect-free.
• Eddy Current Testing (ECT): Quickly detects surface and near-surface defects, improving inspection efficiency.
• Hardness Testing: Assesses pipe hardness to ensure wear resistance and reliability.
• Spectral Analysis: Precisely measures alloy element content to ensure compliance with international standards.

Our quality control workshop is equipped with advanced testing equipment and experienced engineers, ensuring that every batch of products undergoes rigorous inspection before shipment. Through a comprehensive inspection system, our seamless steel pipes have earned the trust of customers in domestic and international markets.

Seamless Steel Pipe Warehouse

Our seamless steel pipe warehouse operates under modern management standards, with each pipe carefully inspected and sorted to ensure that all products leaving the warehouse meet high-quality standards.
