To access the full standards with specific details, you would need to purchase them from an official standards organization or authorized reseller. Please respect copyright laws when accessing and using standards.
APPEARANCE OF EN 10217-1 PIPES
– Jahitan Kimpalan
The weld area of EN 10217-1 pipe is a critical component that must be free from cracks, kekurangan gabungan, and lack of penetration. Any repairs to the weld seam of EW and HFW tubes are not permitted. Repairs to the weld seam of SAW tubes shall be allowed if done by an agreed documented procedure. This is to ensure the structural integrity of the pipe and to prevent any potential leaks.
– Tube Surface
EN 10217-1 pipe has specific requirements for its surface to be considered usable. The tube must be free of any external or internal surface defects that can be detected by a visual examination of the surfaces. Selain itu, the finish and surface condition should not be such that any surface imperfections would require dressing. Namun begitu, if it is necessary to dress the surface imperfections, they can only be ground or machined down. The wall thickness in the dressed area must not fall below the specified minimum wall thickness after dressing. Akhirnya, all dressed areas must blend smoothly into the contour of the tube without any visible imperfections.
