  SSAW Steel Pipe Production Process

  Spiral welded pipe is the leader among welded pipes. The spiral welded pipe manufacturing process is not only one of the most efficient methods for producing steel pipe, but also offers a high degree of flexibility within the production range of diameters and wall thicknesses. This is why spiral welded pipe production began in areas where other welded pipe production processes were limited—whether producing transmission pipe, water pipe (AWWA), or oil and gas pipe (API).

  Seamless High-Pressure Boiler Tubes

  Against the backdrop of my country's rapid economic growth, the electric power industry, as a foundational industry, has experienced rapid development. Electricity is not only a source of power for industrial production but also a vital guarantee for people's daily lives. With increasing energy demand and the widespread construction of thermal power plants, the demand for high-pressure boiler tubes has steadily increased. As a key component of power plant boilers, seamless high-pressure boiler tubes play an irreplaceable role in energy equipment manufacturing.

  Surface rust removal treatment of SSAW steel pipe

  With the continued economic growth of my country, the country is vigorously developing the energy industry. Long-distance oil and gas pipelines are a crucial means of energy security. During the corrosion protection construction of oil and gas pipelines, the surface treatment of spiral steel pipe is a key factor in determining the service life of the pipeline's corrosion protection. It is a prerequisite for the strong bond between the anti-corrosion coating and the steel pipe. Research institutions have verified that in addition to factors such as the coating type, coating quality, and construction environment, the surface treatment of the steel pipe accounts for approximately 50% of the life of the anti-corrosion coating. Therefore, the surface treatment methods for spiral steel pipes should be strictly adhered to the requirements of the anti-corrosion coating specification for steel pipe surfaces, and continuous research, analysis, and improvement should be made.

  Advantages and Uses of Ductile Iron Pipes in Water Transport

  Water is one of the most vital resources for human life, economic development, and environmental sustainability. To ensure its safe and reliable delivery, the infrastructure used in water transportation must be strong, durable, and efficient. Among the many materials available for water distribution networks, ductile iron pipes (DIP) have emerged as one of the most trusted and widely used solutions. Their unique combination of strength, flexibility, and corrosion resistance makes them an ideal choice for transporting water across long distances, both in urban and rural environments.​

  Effective Methods for Pipe Degreasing and Cleaning

  In industrial production, pharmaceutical systems, petrochemical projects, and irrigation systems, pipes often accumulate oil, rust, and organic deposits during processing, transportation, and use. If not promptly removed, this not only reduces pipeline efficiency but can also lead to corrosion, blockage, and product contamination. Therefore, pipeline degreasing (degreasing) is a crucial process for ensuring pipeline cleanliness and extending its service life.
