Pipe Fitting Caps, commonly referred to as end caps or pipe end closures, are essential fittings used to seal the ends of pipes in various piping systems. At Neonox Overseas, we manufacture and supply a comprehensive range of Caps that meet international quality standards such as ASTM, ASME, DIN, EN, and ISO. Our Caps are available in seamless, welded, and fabricated types to suit different industrial requirements. These fittings are designed to provide a secure and leak-proof closure to pipe ends, ensuring safety, durability, and efficiency across applications.
Caps are primarily used to stop the flow in piping systems, protect pipe ends during storage or transportation, and serve as testing closures for pipelines. Their usage spans across industries such as oil and gas, petrochemicals, power generation, pharmaceuticals, water treatment, marine, and food processing. With precision engineering and strict quality control, our Caps deliver exceptional performance even in the most demanding environments involving high pressure, extreme temperatures, and corrosive media.
We supply Caps in a wide variety of materials to meet specific service conditions. Stainless Steel Caps (304, 304L, 304H, 316, 316L, 321, 347, 904L, etc.) are widely used for their excellent corrosion resistance and durability. Duplex and Super Duplex Caps are designed for offshore and marine industries where resistance to chloride-induced corrosion is critical. Nickel Alloy, Inconel, Hastelloy, Monel, and Titanium Caps are provided for highly corrosive and high-temperature applications. Copper Nickel and Alloy 20 Caps are widely preferred in chemical processing industries due to their exceptional resistance to sulfuric acid and seawater.
Our Caps are available in various sizes, ranging from 1/2” to 48”, with wall thicknesses from Sch 10s to Sch XXS. They can be supplied in beveled, threaded, or plain ends based on customer requirements. Additionally, special customizations such as coating, lining, or non-standard dimensions are offered to meet project-specific needs.
Quality is at the core of Neonox Overseas. All our Caps undergo rigorous testing, including hydrostatic tests, ultrasonic testing, and non-destructive examinations, to ensure superior performance and reliability. With timely deliveries and global export expertise, we have established ourselves as a trusted supplier of pipe fittings across international markets.
By choosing Neonox Overseas for your Caps requirements, you are assured of world-class products, unmatched durability, and compliance with the highest industry standards. Whether for standard piping networks, pressure vessels, or specialized process equipment, our Caps are engineered to deliver maximum performance, making them the preferred choice for industries worldwide.
