Forged Threaded End Cap Fittings Stockists| MSS SP-79, 83, 95, 97, BS 3799
ASME B16.11 Forged End Caps are essential components for securely closing and sealing the ends of pipes in high-pressure systems. Socket weld end caps are designed to be welded onto the pipe, providing a permanent, leak-proof seal ideal for high-pressure and high-temperature applications. The pipe is inserted into the cap's socket and welded to create a secure joint.
Threaded end caps feature threads on the inside that allow for easy screwing onto the pipe, making them perfect for low-pressure systems or applications where disassembly is required. Whether you need a permanent, secure closure or a removable option, socket weld and threaded end caps provide reliable solutions for pipe end protection.
Ample Alloys excels in providing high-quality ASME B16.11 Forged Threaded End Caps tailored to meet the most demanding industrial applications. With a focus on precision and durability, We ensures that every end cap is manufactured to the highest standards, adhering to ASME B16.11 specifications for reliable, leak-proof pipe end closures. Whether it's a socket weld end cap for high-pressure systems or a threaded end cap for easier installation and removal, Ample Alloys delivers products with exceptional consistency and reliability. Our end caps are rigorously tested for quality assurance, ensuring each piece offers optimal performance in critical applications across industries.
