Pipe caps, frequently referred to as heads, are critical precision fittings engineered to hermetically seal the termination points of piping systems. Specifically designed for high-stakes industrial environments, these components are indispensable in the petroleum, natural gas, thermal power, and nuclear power sectors, where maintaining system integrity and preventing hazardous leaks is paramount.
Manufactured through advanced die pressing techniques, our pipe caps are available in a comprehensive range of high-grade materials, including carbon steel, alloy steel, stainless steel, and low-temperature steel. To ensure global compatibility and safety, all products are strictly manufactured in accordance with international standards such as ASME B16.9-2018 and MSS SP-75-2019.

A pipe cap fits over the end of the pipe, whereas a plug fits inside the pipe. Caps generally provide a more robust seal for larger diameters in pressure vessel manufacturing.
For corrosive environments, stainless steel or specialized alloy steels are recommended due to their high chromium and nickel content, which form a protective oxide layer.
Die pressing ensures uniform wall thickness and structural integrity, reducing the likelihood of stress concentrations that could lead to failure under high pressure.
Yes, we offer low-temperature steel caps specifically designed to maintain ductility and strength in cryogenic or sub-zero industrial environments.
ASME B16.9 is the industry gold standard for factory-made wrought butt-welding fittings, ensuring safety and precision in high-pressure systems.
The schedule relates to the wall thickness. You should match the cap's schedule (e.g., SCH40 or SCH80) to the wall thickness of the pipe it is sealing to ensure a smooth weld joint.
