Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

Introducing an exceptional spiral wound gasket from Ningbo Dongheng Sealing Co., Ltd., crafted with precision and innovation. This remarkable gasket showcases a sturdy and meticulously engineered outer ring, complemented by an advanced inner ring crafted from premium 304 alloy for enhanced durability. The inner ring is a marvel of design, significantly boosting gasket performance by ensuring impeccable centering on the flange face, thanks to its expertly designed external guide ring. This vital inner component not only safeguards the gasket from collapse during installation but also expertly resists extreme temperatures and corrosive mediums, providing unparalleled protection. Its purpose is to perfectly seal the space between flanges, thus preventing erosion and substantially lowering the risk of malfunction. Complying with the rigorous DIN 2699 standards, it is mandatory for all spiral wound gaskets, especially those utilizing PTFE or graphite fillers, as recognized by ASME B16.20 standards. This adaptable design is not only ideal for raised and flat-faced flanges but also demonstrates superior radial strength, preventing blowouts and acting as an essential compression stop. The outer ring, meticulously fashioned from either painted or zinc-plated carbon steel, wards off corrosion. For more demanding environments, it is optionally available in high-grade alloys to endure elevated temperatures and challenging conditions.
