ASTM A403 / ASME SA403 / EN10253-4 WP316L 1.4404 CAP STAINLESS STEEL BUTT WELD FITTING

Overview:

The 316L cap is an end fitting used to seal the end of a pipe or tube made from stainless steel alloy 316L. It is designed with a convex or flat top and a cylindrical body that fits over the pipe end. The cap is available in various sizes and connection types such as threaded, socket weld, or butt weld.

One of the notable features of the 316L cap is its excellent corrosion resistance, especially in chloride-rich environments. It is resistant to corrosion, oxidation, and pitting, making it suitable for applications in industries such as chemical processing, pharmaceuticals, food and beverage, and oil and gas.

The 316L cap is commonly used to provide a secure closure to prevent leakage or contamination in piping systems. It is highly dependable and can withstand various temperatures and pressures, depending on the specific design, size, and applicable standards.

GENERAL NOTE: The shape of these caps shall be ellipsoidal and shall conform to the requirements given in the ASME Boiler and Pressure Vessel Code.
NOTES:
(1) Length E applies for thickness not exceeding that given in column “Limiting Wall Thickness for Length, E.”
(2) Length E1 applies for thickness greater than that given in column “Limiting Wall Thickness for Length, E” for NPS 24 and smaller. For NPS 26 and larger, length E1 shall be by agreement between the manufacturer and purchaser.

Application:

1. Chemical Processing: 316L caps are widely used in chemical plants and refineries to seal the ends of piping systems handling corrosive chemicals, acids, and solvents. Their corrosion resistance and compatibility with a range of chemicals make them suitable for preventing leakage and ensuring system integrity.

2. Pharmaceutical and Biotechnology: In pharmaceutical and biotech industries, 316L caps are utilized in piping systems involved in drug manufacturing, sterile processing, and sanitary applications. They provide a hygienic closure, preventing contamination and maintaining the integrity of the process.

3. Food and Beverage: The food and beverage industry relies on 316L caps for sealing piping systems in food processing, breweries, dairy plants, and beverage production. The caps ensure food safety and prevent contamination by maintaining a secure and hygienic connection.

4. Water Treatment: Water treatment facilities and desalination plants use 316L caps to seal the ends of pipes in applications such as filtration systems, reverse osmosis, and water distribution. The caps provide corrosion resistance and prevent the entry of contaminants into the water supply.

5. Oil and Gas: In the oil and gas industry, 316L caps are employed in piping systems involved in upstream, midstream, and downstream operations. They are used in offshore platforms, pipelines, refineries, and petrochemical plants, offering corrosion resistance and sealing capabilities in harsh environments.

6. General Industrial Applications: The versatility of 316L caps extends to general industrial applications where sealing and corrosion resistance are crucial. They find use in power generation, pulp and paper mills, wastewater treatment, and other industrial processes.
