D-type pipes (pipes with a semi-circular or D-shaped appearance) are commonly used in the construction industry due to their unique cross-sectional shape, high space utilization, and flexible installation. They are commonly used in the following scenarios: 1、 Drainage system 1. Toilet/kitchen drainage Installed at the corner of the wall or floor, using the curved outer side of the D-shaped pipe to fit the wall corner, concealed installation can save space and avoid the problem of right angle pipes being easily blocked.
Circular pipes are widely used in many fields, and their advantages are mainly reflected in the following aspects: 1. High structural strength: The circular cross-section of the circular tube ensures uniform force distribution in all directions, allowing it to withstand significant pressure and external forces. Compared to other shapes of pipes, such as square pipes, round pipes are less prone to deformation and rupture when subjected to the same external force, and have higher compressive strength and resistance to torsion. This makes circular pipes widely used in load-bearing components in fields such as building structures, bridge engineering, and mechanical manufacturing.
The high strength of the circular tube structure is mainly due to its unique circular cross-section, and the specific reasons are as follows: 1.Uniform stress distribution: When a circular tube is subjected to external forces, the force will be evenly distributed along the circumference, so that the stress on each point of the tube wall is relatively consistent and there will be no stress concentration phenomenon. In contrast, square or other shaped pipes are prone to stress concentration at corners and other locations, making them more prone to damage.
The elliptical flat tube has the following advantages in shape: 1. Unique and beautiful appearance: The elliptical shape of the elliptical flat tube gives it smooth lines and a unique appearance. Compared to traditional circular or square pipes, it has a more modern and fashionable feel, which can add unique visual effects to products or buildings. It is commonly used in occasions with high external design requirements, such as decoration engineering, furniture manufacturing, etc.
Rectangular tubes are widely used in the field of rail transit, and the following are some main aspects: 1.Vehicle body structure Vehicle body frame: Rectangular tubes are often used to manufacture vehicle body frames for subways, light rails, high-speed trains, and other vehicles. Due to its high strength and stiffness, it can effectively reduce vehicle weight, improve operational efficiency and energy utilization while ensuring overall structural stability of the vehicle. For example, the body frame of some new subway vehicles is welded with high-strength rectangular tubes, which not only meets the strength requirements of the vehicle during operation, but also achieves lightweight design and reduces operating costs.
D-type pipes are widely used in fluid transportation. The following are some common areas: 1. building water supply and drainage system Water supply pipe: D-type pipe can be used for cold water and hot water supply system of buildings. The larger inner diameter can meet a certain water flow demand, and can withstand a certain water pressure to provide stable water supply for each water consumption point.
