What is the difference between A106 and A333 pipe?
The difference between ASTM A333 and ASTM A106 is that ASTM A333 is a low-temperature carbon steel pipe that can be used as a structural pipe, while ASTM A106 is a non-structural carbon pipe that is used in high-temperature applications.
ASTM A106 seamless steel pipe is an American standard seamless steel pipe made of ordinary carbon steel series.
A106 includes A106-A and A106-B. The former is equivalent to the domestic 10# material, and the latter is equivalent to the domestic 20# material. It belongs to the ordinary carbon steel series and is one of the commonly used materials. ASTM A106 seamless steel pipe includes two processes: cold drawing and hot rolling. In addition to the different production processes, the two are different in precision, surface quality, minimum size, mechanical properties, and organizational structure. It is widely used in various industries such as petroleum, chemical industry, boilers, power stations, ships, machinery manufacturing, automobiles, aviation, aerospace, energy, geology, construction and military industry.
ASTM A106 Seamless Steel Pipe Pressure Calculation Method
S choose S=8; P is less than 17.5MPa seamless steel pipe, S is the safety factor seamless steel pipe, the wall thickness is 3mm, the pressure the pipe can withstand P= (2*σ/S*δ)/D
Taking A333 low-temperature steel as an example, the use temperature is divided into -45℃ (Gr.1 and Gr.6), -60℃ (Gr.10), -75℃ (Gr.7 and Gr.9), -100℃ (Gr. .3 and Gr.4) and -195℃ (Gr.8 and Gr.11), a total of 5 levels.
