Here are some especially important aspects of quality: Material The incoming material is supplied with test certificates only from qualified manufacturers and according to our stated material specifications. Manufacturing During forming and welding, the operators continuously control that the links meet the speci ed dimensions both before and after welding. Single link samples are continuously mandrel tested on the weld. Shape, dimensions and deburring are then inspected visually. Sample lengths are heat treated and then destruction load tested. Following these tests, the chain is heat treated. Hardening and tempering is carried out continuously in computer controlled induction furnaces with regular samplings. Proof Force The entire chain is test loaded. The manufacturing proof force for short link chain is 2.5 times the permitted working load limit. This gives the chain high safety in use. The chain is then visually inspected and cut into delivery lengths. A sample is taken from every length and tested to destruction. Dimensions and shape are also checked. All results are documented. Chains are divided into grades based on minimum nominal breaking stress. SWE 10G 10G H 4 Marking and Traceability The international standards for lifting chain require that the chain is marked with Grade and Manufacturers ID. On our chain we stamp “SWE - 10G - H - 10G - 4”, where the “H” and the “4” is the combination for the traceability code. In case of the unlikely event of chain failure, we can trace the specific chain link back to the very batch and raw material as well as the year and place of manufacture. Each individual delivery length also has its unique batch number. Technical Information
