End Cap is a pipe fitting used to close pipe ends, typically welded to the end of pipes to seal the pipeline, preventing medium leakage or external impurities from entering. The product is widely used in various pipeline systems for temporary or permanent plugging of pipes, and can also be used for pressure testing of pipeline systems. End caps are manufactured using high-quality stainless steel materials with excellent corrosion resistance and mechanical strength, suitable for pipeline systems conveying various media. The end cap has a reasonable design with good sealing performance and simple installation, making it an indispensable important component in pipeline systems. The product is strictly manufactured according to international and national standards such as ASME, ANSI, and GB to ensure product quality and safety performance. The end cap surface undergoes polishing treatment with high smoothness, suitable for applications with high hygiene requirements.
