Stainless Steel Pipe Manufacturer Stainless Steel 304 316l 904 Pipe 300 Series Alloy for Industry

Introduction to Our Stainless Steel Pipes

Our company specializes in manufacturing high - quality stainless steel pipes, offering a wide range of options including Stainless Steel 304, 316L, and 904 pipes from the 300 series alloy, specifically designed for industrial applications. These pipes are crafted with precision and adhere to the highest quality standards, ensuring durability and performance in various industrial environments.

Material and Composition

• Stainless Steel 304: This is one of the most commonly used grades in our stainless - steel pipe range. It contains approximately 18% chromium and 8% nickel. The high chromium content provides excellent corrosion resistance, while the nickel enhances the pipe's formability and toughness. In industrial settings, it can withstand mild corrosive environments, making it suitable for applications such as food processing, beverage production, and general construction.

• Stainless Steel 316L: With a composition of about 16 - 18% chromium, 10 - 14% nickel, and 2 - 3% molybdenum, the 316L grade offers superior corrosion resistance compared to 304. The addition of molybdenum makes it highly resistant to pitting and crevice corrosion, especially in chloride - rich environments. It is often used in marine applications, chemical processing plants, and pharmaceutical industries.

• Stainless Steel 904: This is a super - austenitic stainless steel with a high nickel (23 - 28%), chromium (19 - 23%), and copper (1 - 2%) content. It provides excellent resistance to a wide range of corrosive substances, including sulfuric acid, phosphoric acid, and many organic acids. In industries where exposure to harsh chemicals is common, such as the chemical and petrochemical sectors, 904 pipes are the ideal choice.

Manufacturing Process

• Hot Rolling and Cold Rolling: Our pipes are manufactured using both hot - rolling and cold - rolling techniques. Hot rolling is used to initially shape the steel into rough pipe forms. This process involves heating the steel above its recrystallization temperature and passing it through rollers. It allows for the production of large - diameter pipes with a relatively thick wall. Cold rolling, on the other hand, is used to further refine the pipes. It improves the surface finish, dimensional accuracy, and mechanical properties of the pipes. The cold - rolled pipes have a smoother surface and tighter tolerances, which are crucial for many industrial applications.

• Surface Treatment: Each pipe undergoes a complete surface treatment process. This includes pickling, passivation, and polishing. Pickling removes any scale or impurities from the pipe's surface, while passivation forms a protective oxide layer that enhances corrosion resistance. Polishing gives the pipes a smooth and aesthetically pleasing finish, which is not only important for appearance but also helps in reducing friction and preventing the accumulation of contaminants.

Product Features

• Strength and Durability: Our stainless - steel pipes possess high strength and can withstand high - pressure and high - temperature conditions. They are designed to have a long service life, reducing the need for frequent replacements in industrial operations. This durability translates into cost savings for our customers in the long run.

• Dimensional Accuracy: We ensure strict control over the dimensions of our pipes. The outer diameter, wall thickness, and length of each pipe are precisely measured and meet international standards. This dimensional accuracy is essential for proper installation and connection in industrial systems, ensuring a leak - free and efficient operation.

• Versatility: The 300 series alloy pipes can be used in a wide variety of industrial applications. Whether it's for transporting fluids, gases, or as structural components, our pipes can adapt to different requirements. They can be easily welded, bent, and fabricated according to specific project needs.

Quality Assurance

• ISO 9001 Certification: Our manufacturing process is certified under the ISO 9001 quality management system. This means that every step, from raw material sourcing to the final product inspection, is carefully monitored and controlled. We conduct regular quality audits to ensure that our products consistently meet or exceed customer expectations.

• Testing and Inspection: Each pipe undergoes a series of rigorous tests, including non - destructive testing such as ultrasonic testing and magnetic particle inspection to detect internal and surface defects. We also perform mechanical property tests such as tensile testing and hardness testing to ensure that the pipes have the required strength and toughness.

Applications

• Chemical Industry: In chemical plants, our stainless - steel pipes are used to transport various chemicals, acids, and alkalis. The corrosion - resistant properties of these pipes ensure the safe and efficient transfer of these substances without the risk of leakage or contamination.

• Oil and Gas Industry: For oil and gas exploration, production, and refining, our pipes can handle high - pressure and high - temperature fluids. They are used in pipelines, wellheads, and refinery equipment, where reliability and performance are of utmost importance.

• Food and Beverage Industry: The hygienic properties of our stainless - steel pipes make them suitable for food and beverage processing. They can be used for conveying liquids, such as milk, juice, and beer, without imparting any taste or odor to the products.
