The role of fastener surface treatment: First, improve anti-corrosion performance Corrosion resistance: The surface treatment of fasteners can significantly improve the corrosion resistance of fasteners and extend their service life. Different surface treatment processes, such as electroplating, hot dip galvanizing, dacromet, etc., can provide different degrees of corrosion protection for fasteners. Adhesion: Through surface treatment, a solid layer of coating or coating can be formed on the surface of the fastener, which can be tightly attached to the base material to prevent the corrosive medium from directly contacting the base material, thus playing a anti-corrosion role. Second, beautify the appearance Aesthetic: Fastener surface treatment can also give fasteners a beautiful appearance. For example, the electroplating process can provide a bright, uniform metal surface for fasteners, while the dacromet process can form a unique grayish-black coating to meet different aesthetic needs.

The major advantage of using a metal bellows seal is the removal of a semi-dynamic sliding elastomer from a conventional pusher type mechanical seal. This removes the potential for mechanical seal hang-up or shaft/sleeve fretting. With 50% more bellows than the industry standard (12 instead of 8) there is less stress on each convolution in the bellows stack which helps increase seal life. AESSEAL® standard bellows material, Alloy 276, has superior mechanical and corrosion resistance properties than other industry standard bellows materials such as 300 series Stainless Steel or Alloy 20. The hydraulically balanced bellows unit is available in a variety of different material options with either elastomer or graphite packing sealing rings.
