Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

Discover the excellence of our spiral wound gasket, engineered with precision and durability in mind. Featuring a robust outer and inner ring, this gasket is designed to maximize performance. The meticulously added inner ring enhances stability, preventing any risk of implosion during installation. It safeguards the sealing element from extreme temperature variations and harsh media, filling the gap between flanges to avert erosion and reduce failure risks. Crafted typically from the same alloy as the winding, the inner ring adheres to the stringent DIN 2699 standard, mandating its inclusion in all spiral wound gaskets. Essential for PTFE fillers under ASME B16.20 standards, and highly recommended for graphite fillers, this design is ideally suited for raised and flat-faced flanges. The outer ring amplifies radial strength, preventing blowouts and serving as a compression limiter, often crafted from carbon steel with protective coatings or available in specialized alloys for high-temperature and demanding environments.
