TU14-2-706-86 P38 is a standard for steel rails used in railway systems, particularly in Russia and other former Soviet countries. The standard specifies the requirements for the manufacturing, Dimensi, and mechanical properties of P38 steel rails.

TU14-2-706-86 P38 steel rail are heavy-duty rails commonly used in mainline railways, Trek Industri, and high-speed rail systems. They are made of high-quality carbon steel with a pearlitic structure, which provides excellent strength, Pakai rintangan, and durability under heavy loads and high speeds.

According to TU14-2-706-86, the P38 rail has the following specifications:

– Profil: The rail has a standard profile with a head width of 152 Mm, a head height of 76 Mm, dan ketebalan web 17.6 Mm.
– Panjang: The standard length of the rail is 12.5 Meter, but it can also be supplied in shorter or longer lengths as required.
– Komposisi kimia: The steel used for P38 rails has a specific chemical composition that includes carbon, Mangan, Silikon, Fosforus, Sulfur, dan unsur-unsur lain dalam perkadaran tertentu.
– Sifat mekanikal: The rail must meet specific mechanical properties, termasuk kekuatan hasil, kekuatan tegangan muktamad, Kekerasan, dan kesan keliatan, to ensure its performance and reliability under heavy loads and high speeds.

The TU14-2-706-86 standard also specifies testing methods and acceptance criteria for P38 rails, termasuk teknik ujian yang tidak merosakkan seperti ujian ultrasonik dan pemeriksaan zarah magnetik, to ensure their quality and safety. Keseluruhan, TU14-2-706-86 P38 steel rail is a high-performance rail type that is suitable for demanding applications where high speeds, heavy loads, and long service life are critical factors.
