What is high press pipeline

　The high press pipeline is a pipe that can withstand pressure. It is used to transport the liquid. There are many kinds of pipes, such as steel pipes, copper pipes, stainless steel pipes, and so on. High quality carbon structural steel and alloy structural steel high press pipeline are mainly used for manufacturing steam boilers and pipes with high pressure and above pressure.

　　The high press pipeline is a tubular equipment that uses a certain pressure to transport gas or liquid. Its range is defined as a gas, liquefied gas, vapor medium with a maximum working pressure or equal to 0.1MPa (surface pressure), or a flammable, explosive, toxic, corrosive, maximum working temperature above or equal to a standard boiling point. A liquid medium with a nominal diameter greater than 25mm.

　　High Press Pipeline can be divided into four main categories: class GA (long distance pipeline), GB class (public pipeline), GC class (industrial pipeline), GD class (power piping).

　　Less than 1.5MP is a medium pressure with a low pressure and not greater than 2.5MP. High pressure greater than 2.5MP.
