The steam pipes of the boiler are submitted for inspection as pressure pipes
Thread Content
I vaguely remember that the auxiliary steam pipes of the boiler, **M**, can be inspected together with the boiler during its annual inspection. Which expert remembers in which standard this is specified? Thank you
Units holding a pressure pipeline installation license may install pressure vessels or complete boilers connected to such pipelines simultaneously, with the installation supervision and inspection being carried out by a qualified inspection agency. When the total length of the connection pipes between the boiler and the heat-using equipment is 1000 meters or less, the boiler and its connected pipes can be installed simultaneously by a unit holding a boiler installation license, with installation supervision and inspection carried out by a qualified installation supervision agency; meanwhile, registration for use can be handled along with the boiler. When the total length of the pipelines exceeds 1,000 meters, the pipelines connected to the boiler must be installed by a unit holding a license for the installation of pressure pipelines, and separate registration for the use of those pressure pipelines must be obtained. . . . Are the above regulations true?~~ Where do they come from?
