What is the difference between P195GH pipe and P235GH pipe
P195GH and P235GH are two different steel materials that are mainly used for manufacturing pressure vessels and other important equipment. Here are the main differences between them:
Minimum yield strength:
P195GH: The minimum yield strength is 195MPa.
P235GH: The minimum yield strength is 235MPa.
Chemical composition:
P195GH: The content of carbon (C) does not exceed 0.19%, and the content of manganese (Mn) is between 0.9% and 1.1%.
P235GH: The content of carbon (C) does not exceed 0.16%, and the content of manganese (Mn) is between 0.6% and 1.2%.
Uses:
P195GH: Due to its specific strength and toughness, it is commonly used in the manufacture of pipelines and pressure vessels that require a high pressure tolerance.
P235GH: This material is used in applications that require higher strength and good welding properties, such as chemical equipment and containment in nuclear power plants.
To summarise, although there is some overlap between P235GH and P195GH in terms of use, P235GH is more suitable for use in the manufacture of equipment requiring higher safety and performance standards due to its higher yield strength and excellent welding properties.
