D-type pipe is a type of irregular pipe with a D-shaped shape, mainly used for the following purposes:
1、 Construction field
1. Architectural decoration
      Handrails and railings: D-type pipes can be used to make handrails and railings for both the interior and exterior of buildings. Due to its unique D-shaped cross-section, the flat part can provide a comfortable grip when used as an armrest. For example, using D-shaped pipes on escalator handrails in shopping malls, balcony railings or staircase handrails in residential areas is not only aesthetically pleasing but also practical.
      Decorative lines: In indoor decoration, D-shaped pipes can be used as decorative lines to decorate walls, ceilings, etc. It can add a sense of hierarchy and three dimensionality to the space, and its shape is more distinctive compared to ordinary circular or square pipes. For example, in European style architectural interiors, the use of D-shaped pipes to create corner or waistline lines can highlight the delicacy and magnificence of the building.
2. Structural support
      Lightweight frame structure: In some small buildings or temporary structures, D-pipes can be used as a component of lightweight frame structures. Its unique shape allows it to provide relatively stable support when subjected to certain axial pressure or lateral tension. For example, using D-shaped pipes in the framework of simple warehouse sheds or prefabricated houses can help enhance the stability of the structure.
2、 Furniture manufacturing field
1. Making table and chair legs
      D-type tubes can be used to make legs for tables and chairs. Its shape makes the legs of the table and chairs look more innovative, and compared to traditional circular or square legs, the legs made of D-shaped pipes have a unique visual effect. Moreover, the D-shaped tube can better contact the ground in the flat part, increasing the stability of the table and chairs. For example, in modern minimalist furniture design, the legs of D-shaped tube tables and chairs can reflect a simple yet not monotonous design concept.
2. Bed frame and sofa frame
      D-type pipes are also used in the production of bed frames and sofa frames. It can provide good support performance, and the shape of the D-tube is easy to connect with other components. For example, in the design of some metal bed frames, D-pipes can be used as the main body of the bed frame, connected to the headboard, footboard, and bed support components through welding or bolt connections to ensure the stability of the bed frame.
3、 Industrial sector
1. Pipeline system for transportation
      Material conveying: In some material conveying systems with special requirements for the shape of the conveying pipeline, D-type pipes can play a role. For example, in some food processing plants, D-shaped pipes can be used as special shaped conveying pipelines to transport block shaped foods with regular shapes, such as biscuits. The flat part of the D-shaped tube can prevent food from rolling freely during transportation, ensuring orderly delivery.
      Fluid transport: For some fluid transport scenarios, D-type pipes are also used. It can be connected to other pipelines or equipment through special connection methods to transport fluids with strong adaptability to pipeline shapes. For example, in some small-scale chemical plants, D-type pipes can be used as transport pipelines for experimental fluids, and their unique shape facilitates the observation of fluid flow in the pipeline.
2. Equipment protection and support
      Equipment protective fence: D-shaped pipes can be used to make protective fences around industrial equipment. It can prevent personnel from accidentally coming into contact with high-temperature, high-speed rotating or electrified equipment components, playing a role in safety protection. For example, D-shaped pipe guardrails are installed around stamping machines, milling machines, and other equipment in the factory to protect the safety of operators.
      Equipment support structure: D-type pipes can also serve as support structures for small industrial equipment. It can flexibly adjust the support method according to the shape and weight distribution of the device. For example, in some electronic equipment production workshops, D-tubes can serve as support legs for small testing equipment, providing stable support for the equipment.
