Steel chain approaching stainless steel chain in corrosion resistance
Double Guard Chain is highly corrosion resistant with coating of double layers of two various elements. In comparison to the High-Guard Chain, it exhibits just about doubled corrosion resistance while in the salt water spray test, and may be utilized in mild alkaline and mild acidic situations.
Attributes
?With its enhanced corrosion resistance, it could possibly be used in situations where High-Guard or Rustless Chains are unable to be employed, and in many cases in some conditions exactly where only stainless steel can be employed.
?The coating consists of environmentally friendly non-chrome materials. To comply using the EU’s Restriction of Hazardous Substances (RoHS) Directive, hexavalent chromium just isn’t utilized.
Advisable makes use of
?Conditions that need the two strength and corrosion resistance
Multilevel parking facility, moving decks, cleansing lines and so forth. ?Circumstances exposed to rain or sea water
Machines installed outdoors, amusement machines
?Disorders exposed to mild alkaline and mild acidic chemical agents, sea water or wastewater. Many chemical plants and water treatment plants.
Choice of chains
Double Guard Chain has an equivalent strength to a typical roller chain.
Connecting links and offset hyperlinks
R connecting back links are utilized for high-guard chains #60 or smaller and C connecting back links for #80 or greater, and OJ and 2POJ are applied as offset backlinks.
Sprockets
Common sprockets for high-guard chains is often employed since the dimensions would be the same as regular roller chains.
Caution
Use stainless steel chains when the chains will are available in direct speak to with foods.
Double Guard chain will not have a gloss just like the nickel coated chain.
Unless not so specified through the client, chains are coated with grease and shipped. If attainable, oil the spaces concerning pins and bushes and bushes and rollers. Please make use of the advisable lubrication oil for that maintenance in the chain as oiling with grease could cause flexion failure.
