Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

Introducing a revolutionary product by Ningbo Dongheng Sealing Co., Ltd., the Durable Metal Gasket with 316 Inner Ring and Graphite Winding Features. This state-of-the-art spiral wound gasket is expertly engineered to encompass a robust outer structure alongside an advanced inner ring. The inclusion of this inner ring not only elevates gasket efficacy but ensures impeccable centering with its external guide ring on the flange face, promising unparalleled precision. The inner ring is pivotal, safeguarding the gasket from disintegration during installation and offering a formidable defense against extreme temperatures and aggressive environments. It perfectly occupies the gap between flanges, thereby minimizing erosion risks and drastically lowering potential failure rates. Crafted from the same premium alloy as the winding, the inner ring complies with the rigorous DIN 2699 standard, a testament to its necessity in all spiral wound gaskets. For versions utilizing PTFE filler, the ASME B16.20 standards also mandate inner rings, affirming their critical role in conjunction with graphite fillers. This adaptable design is impeccably suited for both raised and flat-faced flanges. The external ring enhances radial stability, preventing blowouts and serving as an essential compression limiter. Typically made from either painted or zinc-plated carbon steel to resist corrosion, the outer ring can also be fabricated from specialized alloys to endure higher temperatures and more challenging substances, thus ensuring the gasket's versatility and durability.
