FEATURES Superior Features of Borusan Natural Gas Pipe Internal burr difference: Only the internal burrs have been removed from all Borusan natural gas pipes. Normalization difference: All Borusan natural gas pipes are subjected to the normalization process with SRM (hot drawing) technology, which is only available at Borusan. Test differences: In Borusan natural gas pipes, each pipe produced is tested twice with both ultrasonic and eddy current methods to ensure continuity of quality. Difference at the delivery stage: In order to easily distinguish Borusan natural gas pipes, it is written on the pipe with a stencil that the natural gas production standard complies with TS EN 10208-2 and that it has the HN (normalized) feature found only in Borusan. Production Range Outer diameter: 21.3mm- 323.9mm Wall thickness: 2.80 mm-9.50 mm Length: 6.0 m (standard) Production Standards API 5L, TS EN 10208-1/2
