Steel chain approaching stainless steel chain in corrosion resistance
Double Guard Chain is highly corrosion resistant with coating of double layers of two distinctive supplies. When compared to the High-Guard Chain, it exhibits just about doubled corrosion resistance inside the salt water spray check, and can be used in mild alkaline and mild acidic situations.
Functions
?With its enhanced corrosion resistance, it could be utilized in situations in which High-Guard or Rustless Chains are not able to be used, as well as in some ailments in which only stainless steel is often used.
?The coating consists of environmentally pleasant non-chrome materials. To comply using the EU’s Restriction of Hazardous Substances (RoHS) Directive, hexavalent chromium is just not applied.
Proposed makes use of
?Circumstances that need each strength and corrosion resistance
Multilevel parking facility, moving decks, cleansing lines and so on. ?Conditions exposed to rain or sea water
Machines installed outside, amusement machines
?Disorders exposed to mild alkaline and mild acidic chemical agents, sea water or wastewater. Various chemical plants and water treatment plants.
Choice of chains
Double 
Guard Chain has an equivalent strength to a common roller chain.
Connecting hyperlinks and offset back links
R connecting links are used for high-guard chains #60 or smaller sized and C connecting hyperlinks for #80 or bigger, and OJ and 2POJ are applied as offset hyperlinks.
Sprockets
Normal sprockets for high-guard chains is often utilised since the dimensions would be the same as standard roller chains.
Caution
Use stainless steel chains in case the chains will can be found in direct get hold of with meals.
Double Guard chain won’t have a gloss such as the nickel coated chain.
Unless not so specified through the consumer, chains are coated with grease and shipped. If attainable, oil the spaces among pins and bushes and bushes and rollers. Please utilize the advised lubrication oil for that upkeep with the chain as oiling with grease could cause flexion failure.
