Fluid Steel Pipe

Fluid Steel Pipe are pipes specially used for conveying media with fluid properties.
Medium with fluid properties, in addition to liquid media such as water, oil, and solution, solid media such as cement, grain, and coal powder can also flow under certain conditions.
The fluid pipe must have a hollow cross-section, and it can also be square, triangular or any other shape. Some equipment is restricted by conditions, and rectangular pipes must be used, but most still use round pipes. The round tube has the smallest perimeter/area ratio in all geometric sections, that is, the largest internal section can be obtained under the same amount of material.
Steel pipes are also an indispensable material for various conventional weapons. Gun barrels and barrels are all made of steel pipes. Steel pipes can be divided into round pipes and special-shaped pipes according to different cross-sectional area shapes. Because the circle area is the largest under the condition of equal circumference, the circular pipe can transport more fluids, and is widely used to transport oil, natural gas, gas, water and certain solid materials.
