304 316 409 Welded Stainless Steel Pipe Tube Manufacturer with Factory Price

304, 316, 409 Welded Stainless Steel Pipe Tube: A Premium Choice for Global Buyers

1. Product Overview

Our company specializes in manufacturing high - quality 304, 316, and 409 welded stainless steel pipes and tubes. These pipes are crafted with precision and adhere to strict quality standards. Stainless steel is renowned for its durability, corrosion resistance, and aesthetic appeal, making our products suitable for a wide range of applications across various industries.

2. Material Characteristics

• 304 Stainless Steel: This is one of the most widely used grades of stainless steel. It contains approximately 18% chromium and 8% nickel, which gives it excellent corrosion resistance in most environments. 304 stainless steel pipes are resistant to oxidation and can withstand a moderate amount of heat. They are commonly used in food processing equipment, architectural applications, and general - purpose piping systems.
• 316 Stainless Steel: With the addition of molybdenum (around 2 - 3%), 316 stainless steel offers enhanced corrosion resistance, especially in chloride - rich environments such as coastal areas or chemical processing plants. It is more resistant to pitting and crevice corrosion compared to 304. Applications include marine equipment, medical devices, and chemical handling systems.
• 409 Stainless Steel: A ferritic stainless steel, 409 contains lower amounts of nickel and higher amounts of chromium. It is known for its good resistance to high - temperature oxidation and is often used in automotive exhaust systems, heat exchangers, and other applications where exposure to elevated temperatures is expected.

3. Manufacturing Process

Our pipes and tubes are manufactured using advanced hot - rolling and cold - rolling techniques. The hot - rolling process involves heating the stainless steel billets to a high temperature and then passing them through a series of rollers to achieve the desired shape and size. This process improves the mechanical properties of the steel and gives it a uniform grain structure. Cold - rolling is then applied to further refine the surface finish and dimensional accuracy of the pipes. After the rolling processes, the pipes undergo a complete surface treatment to remove any impurities and enhance their corrosion resistance. Welding is carried out using state - of - the - art equipment and techniques to ensure strong and reliable joints.

4. Product Specifications

• Size Range: We offer a wide range of sizes for our welded stainless steel pipes and tubes, from small - diameter tubes used in precision applications to large - diameter pipes for industrial infrastructure. The outer diameter can range from a few millimeters to several inches, and the wall thickness can be customized according to the specific requirements of our customers.
• Length: The pipes can be supplied in standard lengths or cut to custom lengths as requested. This flexibility allows our customers to minimize waste and optimize their projects.
• Tolerance: Our products are manufactured with tight tolerances to ensure consistent quality. The dimensional tolerances for outer diameter, wall thickness, and length are in line with international standards, guaranteeing a perfect fit in any application.

5. Quality Assurance

As a manufacturer with ISO9001 certification, we have a comprehensive quality control system in place. Every step of the manufacturing process, from raw material inspection to final product testing, is carefully monitored. We conduct various tests, including non - destructive testing (such as ultrasonic testing and X - ray testing) to detect any internal defects, and mechanical property testing (such as tensile testing and hardness testing) to ensure the pipes meet the required strength and durability standards.

6. Applications

• Industrial: Our stainless steel pipes and tubes are widely used in the chemical, petrochemical, and power generation industries. They are used for transporting corrosive chemicals, high - pressure fluids, and steam.
• Architectural: In the construction industry, these pipes are used for structural support, handrails, and decorative elements. Their sleek appearance and corrosion resistance make them an ideal choice for both indoor and outdoor applications.
• Automotive: 409 stainless steel pipes are commonly used in automotive exhaust systems due to their high - temperature resistance and durability.
• Food and Beverage: 304 stainless steel pipes are the preferred choice for food processing and beverage production equipment, as they are hygienic and resistant to corrosion from food acids.
