High-pressure steam pipeline has been out of use for 4 years and is put back into operation
Thread Content
Dear experts, a high-pressure steam pipeline that has been out of use for 4 years needs to undergo chemical cleaning before being put back into use. Is it necessary to carry out impact testing? Are there any relevant standards for this? :handshake:handshake
Reference can be made to the \"Rules for the Registration and Management of the Use of Pressure Pipelines\"
As shown in the figure, but it’s best to contact the local security authorities to confirm, as there are differences in how this is implemented from place to place
Re-registration is required to make it legal; using it after testing is compliant. But would you dare to use high-pressure steam from the generator set without conducting tests first?
