Product Description

Product Description of ASTM A358 SS Welded 304, 316 EFW Pipe

1. Physical Specifications

Specification	Details
Diameter	The pipe is available in a broad spectrum of diameters. It can range from small - sized diameters like 1/2 inch (12.7 mm) which are suitable for intricate plumbing or instrumentation systems, up to large - scale diameters of 48 inches (1219.2 mm) for major industrial pipelines. Custom diameter sizes can also be fabricated as per specific project requirements.
Wall Thickness	Wall thicknesses are designed to meet different pressure and application needs. They can vary from thin - walled options such as 0.083 inches (2.108 mm) for applications with lower pressure requirements to thick - walled ones up to 1.5 inches (38.1 mm) for high - pressure and heavy - duty operations. The wall thickness is precisely controlled during the manufacturing process to ensure consistent quality.
Length	Standard lengths typically include 20 feet (6.096 meters) and 40 feet (12.192 meters), which are convenient for transportation and installation in most projects. However, cut - to - length pipes can be provided as well. The ability to offer custom lengths allows for a perfect fit in various construction and industrial setups, from short - run connections to long - distance pipelines.
Surface Finish	The pipe has a smooth and uniform surface finish. The internal surface is polished to reduce friction and prevent the build - up of contaminants, which is especially important for applications involving the flow of fluids. Externally, it can have a mill finish or a more refined finish such as a brushed or mirror finish, depending on the application requirements and aesthetic preferences.

2. Material Properties

• Stainless Steel Grades: This pipe is made from high - quality austenitic stainless steel grades 304 and 316. Grade 304 offers good general corrosion resistance in a wide range of environments, including mild chemical exposure and atmospheric conditions. Grade 316, on the other hand, contains molybdenum, which enhances its resistance to pitting and crevice corrosion, making it particularly suitable for applications in chloride - rich environments such as marine and coastal areas.
• High - Temperature Resistance: The pipe can withstand elevated temperatures without significant degradation of its mechanical properties. It is suitable for use in high - temperature processes such as heat treatment furnaces, power generation plants, and chemical reactors. The stainless steel composition provides excellent thermal stability, ensuring reliable performance over a long period of time.
• Weldability: Being an Electric Fusion Welded (EFW) pipe, it has excellent weldability. The welding process used in its manufacturing results in strong and durable weld joints, which are essential for maintaining the integrity of the pipeline system. This allows for easy installation and connection of the pipes in various industrial settings.

3. Applications

• Chemical Processing: Due to its corrosion resistance, it is widely used in chemical plants for transporting corrosive chemicals, acids, and alkalis. It can handle a variety of chemical substances without being affected by corrosion, ensuring the safety and efficiency of the chemical processes.
• Petrochemical Industry: In refineries and petrochemical complexes, this pipe is used for pipelines carrying petroleum products, natural gas, and other hydrocarbon - based fluids. Its high - temperature and corrosion - resistant properties make it an ideal choice for these demanding applications.
• Power Generation: It is employed in power plants for steam and water piping systems. The pipe's ability to withstand high temperatures and pressures makes it suitable for use in boilers, condensers, and other power - generating equipment.
• Food and Pharmaceutical Industries: In food processing plants and pharmaceutical facilities, the pipe's hygienic surface finish and corrosion resistance make it suitable for transporting food products, beverages, and pharmaceutical ingredients. It meets the strict hygiene and quality standards required in these industries.

ASTM A358 Grade 304	Carbon ≤ 0.08%, Manganese ≤ 2.00%, Phosphorus ≤ 0.045%, Sulfur ≤ 0.030%, Silicon ≤ 0.75%, Chromium 18.0 - 20.0%, Nickel 8.0 - 11.0%	205 MPa (30 ksi)	515 MPa (75 ksi)	35%	A general - purpose austenitic stainless steel grade with good corrosion resistance and formability. Commonly used in pipeline systems in industries such as chemical, food processing, and architectural decoration for transporting various less - corrosive liquids and gases.
ASTM A358 Grade 304L	Carbon ≤ 0.03%, Manganese ≤ 2.00%, Phosphorus ≤ 0.045%, Sulfur ≤ 0.030%, Silicon ≤ 0.75%, Chromium 18.0 - 20.0%, Nickel 8.0 - 12.0%	170 MPa (25 ksi)	485 MPa (70 ksi)	35%	A low - carbon version of 304 stainless steel. The reduced carbon content minimizes sensitization during welding, enhancing the corrosion resistance of the welded areas. Frequently used in welded structures and pipelines, such as pressure vessels and heat exchangers.
ASTM A358 Grade 316	Carbon ≤ 0.08%, Manganese ≤ 2.00%, Phosphorus ≤ 0.045%, Sulfur ≤ 0.030%, Silicon ≤ 0.75%, Chromium 16.0 - 18.0%, Nickel 10.0 - 14.0%, Molybdenum 2.0 - 3.0%	205 MPa (30 ksi)	515 MPa (75 ksi)	35%	Contains molybdenum, which enhances pitting and crevice corrosion resistance in chloride - containing environments. Widely applied in industries like marine engineering, pharmaceuticals, and papermaking, especially in corrosive environments with chloride ions.
ASTM A358 Grade 316L	Carbon ≤ 0.03%, Manganese ≤ 2.00%, Phosphorus ≤ 0.045%, Sulfur ≤ 0.030%, Silicon ≤ 0.75%, Chromium 16.0 - 18.0%, Nickel 10.0 - 14.0%, Molybdenum 2.0 - 3.0%	170 MPa (25 ksi)	485 MPa (70 ksi)	35%	A low - carbon 316 stainless steel with similar corrosion resistance to 316. However, due to its low carbon content, it has better weldability and reduces the risk of intergranular corrosion in the welded zone. Commonly used in industries such as chemical, food and beverage, and medical equipment for welded structures and pipelines.
ASTM A358 Grade 321	Carbon ≤ 0.08%, Manganese ≤ 2.00%, Phosphorus ≤ 0.045%, Sulfur ≤ 0.030%, Silicon ≤ 0.75%, Chromium 17.0 - 19.0%, Nickel 9.0 - 12.0%, Titanium ≥ 5 × (C + N)	205 MPa (30 ksi)	515 MPa (75 ksi)	35%	Contains titanium, which stabilizes carbon and prevents the formation of chromium carbide at high temperatures, thus improving intergranular corrosion resistance. Suitable for high - temperature applications, such as pipelines and components in aerospace, petrochemical, and heat - treatment equipment.
