ASTM A335 High Pressure High Temperature PipeASTM A335 High Pressure High Temperature Pipe in compliance with ASTM A335 standard is the core pipe material in the high-parameter industrial field. As a professional Alloy Steel Pipe (mostly using chromium-molybdenum alloy base material), it has excellent high-pressure load-bearing capacity and high-temperature creep resistance performance. It can operate stably for a long time in extreme working conditions such as the main steam pipeline of power station supercritical boilers and high-pressure hydrogenation units in petrochemicals, ensuring the safe transmission of high-parameter media. Compared with the conventional Carbon Steel Pipe, it has better strength and fatigue resistance in the superimposed environment of high temperature and high pressure, and can avoid frequent failure replacement. For the low-temperature auxiliary pipelines in the system, it can be used in combination with Low Temperature Steel Pipe to form full-temperature…
