EC declaration of conformity available upon request. (See contact details on page 13)  Ref:THM 13004Issue: 05/04/2006Page4of14 INTRODUCTION The parameters appertaining to post weld heat treatment are clearly defined in the appropriate USA, Britishand European Standards. Postweld heat treatment to these codes may be affected by electrical resistancemethods and the following represents the fundamental requirements for effective heat treatment. ã The system must be fully capable of reaching and correctly recording the specific temperatures. ã Heating conditions must allow for various component thicknesses such that uniform temperatures result.Special provision often has to be made to control temperature gradients away from a heated zone inorder to minimize additional stress. ã The operation has to be recorded and controlled within the limits of specification.The oil refinery, petrochemical and power plant industries all utilise vast quantities of tubing and pipework, asubstantial proportion of which has a preheat and/or postweld heat treatment requirement and this can besuccessfully achieved by the use of Stork CooperheatTwin Heat module.StorkCooperheat equipment is manufactured incorporating ISO 9001:2000 quality controlled designs. Thesedesigns are based upon the results of third party testing for compliance with European Safety Directives andStorkCooperheat ‘s extensive experiencein the field of heat treatment engineering.TheStorkCooperheatTwin Heat modulehas been developed to meet the real needs of the heat treatmentengineering industry. Our design is based on almost 50 years experience as the worldwide market leader inthe field of heat treatment.
