ASTM A335 p5 pipe suppliers produce these ferritic alloy steel pipes for high temperature services. The material has 4-6% chromium and molybdenum, silicon, sulfur, phosphorus, manganese and carbon in the composition. The ASTM A335 gr p5 erw pipe is made through electric resistance welding procedure. They do not require post weld heat treatments and they don’t need to be preheated for welding. Also the SA335 P5 material allows for most conventional methods for welding. The application of these A335 Grade P5 welded pipe types can be seen in sugar, fertilizer, gas processing and petrochemical plants.
ASTM A335 P5 Alloy Steel Seamless Pipe
P5 Alloy Steel Pipe
Also the strength and corrosion resistance of the pipes launch them in applications such as the refineries, machine building, oil and gas and in power generation industrial applications. The minimum tensile strength of the Alloy steel p5 pipes is 415MPa and the minimum yield strength of the pipes is 205MPa. Since the considerable elements in the composition are chromium and molybdenum, these pipes are also known as the A335 P5 Chrome Moly Pipes. The pipes belong to different specifications such as ASTM A369 which is a forged or bored pipe specification.
The pipe is also traded as 5 chrome pipe. The sizes range from ½ inches to 30 inches in nominal bore sizes with schedules varying from 20 through XXS. There are ASME SA335 P5 High Pressure Alloy Pipe types with high wall thicknesses and light wall types as well. Since these pipes are most suitable for heating applications and can withstand high temperatures, the UNS K41245 Pipe is mostly used in heater applications and in super heater elements.
