Structural pipes are general structural steel pipes, referred to as structural pipes. This standard is applicable to seamless steel pipes for general structures and mechanical structures, and the standard for fluid seamless steel pipes is applicable to general seamless steel pipes for conveying fluids. Structural pipes are steel pipes that are used to build various structures, and as they are used to build various structures, several properties need to be achieved. The pressure bearing capacity should be good, and no fracture should occur, otherwise, once an accident occurs, the construction of the entire project will be affected. Durable, can be used for a long time after the project is completed, and will not be damaged and worn for a long time.

Fluid pipes are steel pipes used to transport various liquids and gases such as oil, natural gas, natural gas and water. Since they are used for transportation, fluid pipelines also have their own distinctive features. Good air tightness, no leakage is allowed during transportation, otherwise the gas leaks and the consequences are unimaginable. , Prevent corrosion, because many transported objects are corrosive, if corrosion occurs, the entire project will be affected. The finish of the tube is very demanding, and it needs to meet the requirements to make a fluid tube.

First, strictly speaking, they cannot be shared. Structural pipes require good pressure bearing capacity, while fluid pipes require good sealing properties. Therefore, the purpose of the two is very different. Try not to use the wrong area. Secondly, structural pipes have high cost requirements, otherwise the corrosion resistance or pressure bearing capacity of some steel pipes is not up to standard, and it is easy to damage. Hygiene requirements are more stringent if fluid pipes are used to transport water and food. It can be shared in special cases, and some features are the same, as long as the environmental requirements are not too harsh.
