Butt Weld End Cap
Kaizen Steel Industries is a supplier, and exporter of ASME B16.9 Buttweld End Caps in various forms and sizes. Our Buttweld fittings adhere to the ASME B16.9 standards for dimensions and tolerances.
The ASME B16.9 Buttweld End Cap Pipe Fittings standard includes specifications for pressure-temperature ratings, materials, dimensions, tolerances, marking, testing, and designating openings for fittings.
End Caps, also known as Pipe Caps, seal the ends of pipes. They are designed to protect piping networks from water, chemicals, moisture, and weather. Our end caps are pressure-releasing and flexible, offering durability and resistance.
Our end caps come in high-temperature resistant materials, various colors, finishes, and sizes.
