Manufactured by our unit; qualification for the installation of pressure vessels and their connecting pipelines
Thread Content
1. Can this unit manufacture pressure vessels and their connecting pipes and install them itself? Where can I find the source of the text? According to Article 5.1 of the «Grand Regulations», qualifications are required, but many people say that their own units can install containers they manufacture themselves. Can the pipes connected to the container be installed? If possible, is there any limit on the installation length? Where is it from? 2. As a follow-up question, is it necessary to obtain certification for modifying or carrying out major repairs on the unit’s containers? Thank you!
