Advantages for hot galvanising plants

"High Temperature Chain | Pewag Winner Fire | Solution for Hot Galvanising Plants"

Galvanizing plants use various types of sling chains for lifting and transporting parts to be galvanized and for adding zincingots. Chains, particularly those used during the galvanizing process, are subject to extraordinarily high stress:

 

• They are heated up to approx. 475°C in the galvanizing bath.
• They are subjected to zinc corrosion.
• The hydrogen that develops during the repeated work cycles of „galvanizing – pickling – galvanizing“ in the galvanizing bath has a considerable effect on the chains.

The absorption of hydrogen causes the dreaded stress corrosion cracking which results in component breakage without any signs of deformation or any other previous warning signals. In the case of sling chains, such failure would have dramatic consequences.


With pewag’s special sling chains for hot galvanizing plants you have this problem under control!


This has been proven in renowned European galvanizing plants for several years. (In Germany, pewag austria was the first and only chain manufacturer to receive a special permit from the German trade association which was later replaced by EN 818.) In galvanizing plants, the chains are used in diluted sulfuric or hydrochloric acid of a concentration of 15% at approx. 20-30°C bath temperature. The use of pewag chains offers further important advantages compared to ordinary chains of grade 2 acc.to BGR 150:

• Due to the higher strength (quality grade 4 according to EN818-5), the ratio of load capacity and mass is improved by a factor of 2.6.
• The surface of the chains and thus the undesired zinc dragout is reduced by nearly 30%.
• At high temperatures, pewag’s special sling chains for hot galvanizing plants achieve a 25% higher minimum breaking force than those demanded in EN 818-5 and EN 818-6, which means 25% more safety for the user. The risk of breaking is significantly smaller than with ordinary chains and the level of security 25% higher.

 

Production

All pewag winner fire sling chains are produced in all welded design pursuant to EN 818-5 and afterwards subjected to a special treatment to increase the resistance to stress corrosion cracking. pewag winner fire chain slings must not be modified by the user.

 

Test certificate

Test certificates are issued for each sling chain and must be kept on file for the entire period of usage.

 

"High Temperature Chain Combinations | Pewag Winner Fire | Solution for Hot Galvanising Plants"Possibilities of combination

Pewag winner fire system offers many possibilities of combination.

Our chain slings are produced according to the information provided by the user. Special constructions are also possible. Welding processes are carried out according to BG directives. The original product must not be altered or modified after shipment. If needed, we also provide customized solutions on site.

 

 

Working load limits

The provided working load limits are the maximal values of the
different chain sling types according to the reference method.

Demanding conditions

If pewag special chains are exposed to special conditions (e.g. asymmetry or edge load), the working load limits defined in the table above must be reduced. In such cases, the load factors stipulated in the table below must be applied. Please take the information given by the user manual into consideration. When lifting with chains directly on lugs or round loads, it is recommended to use a lug diameter of at least 3 x the pitch of the chain. If this is not the case, the working load limit must be reduced by 50%.
