Product Description

1. Material: Caps are available in various materials such as carbon steel, stainless steel, alloy steel, and other materials suitable for specific applications. The material used depends on factors such as the type of fluid being conveyed, temperature, pressure, and corrosion resistance requirements.
2. Size: Caps are manufactured in different sizes to fit various pipe diameters. The size is specified in terms of nominal pipe size (NPS) or nominal diameter (DN), which indicates the approximate inside diameter of the pipe.
3. Wall Thickness: Caps are available in different wall thicknesses to meet the pressure and structural requirements of the piping system. The wall thickness is specified according to the schedule of the pipe, which defines the wall thickness based on the nominal pipe size.
4. End Connection: Caps are designed for butt-welding installation, where they are welded directly to the end of the pipe using a butt-welding process. The end connection is typically beveled to facilitate the welding process and ensure a secure and leak-free joint.
5. Standard Compliance: ANSI B16.9 caps are manufactured in accordance with the requirements specified in the ANSI B16.9 standard, which defines the dimensions, tolerances, materials, and testing procedures for butt-welding fittings.
6. Additional Features: Depending on the application and specific requirements, caps may include additional features such as reinforcement ribs, vent or drain holes, and special coatings or treatments for enhanced corrosion resistance.
