  • How To Cut Round Pipe?
    Manual sawing: Use a saw with sharp serrations to cut round pipes. Fix the circular tube on the workbench and start cutting from one end of the tube using pliers to reduce finger injuries. ‌1

    Manual circular saw: Fix the circular tube on the workbench and use a toothed circular saw for cutting. The circular saw can be mounted on a manual drilling machine and cut from one end of the pipe.

    Electric saw cutting: Using an electric saw can improve work efficiency, but safety should be taken into account. Place the chainsaw at one end of the circular tube and gently press it against the saw blade to cut into the tube.

    Welding and cutting: using modern technologies such as laser or plasma cutting, which utilize high thermal energy to achieve fast and precise cutting results, but require specialized equipment and operational skills.

  • How To Weld Round Pipe​ ?
    Circular pipe welding is a common connection process widely used in various industries. When welding circular pipes, we need to choose a suitable welding method to ensure welding quality and efficiency. The common welding methods and characteristics of circular pipes are as follows.

    1. Arc welding
    Arc welding is the use of an electric arc to generate high temperatures and weld workpieces together. Arc welding is suitable for circular pipes of various materials, with fast welding speed and wide applicability, but requires high operational skills.

    2. Gas shielded welding
    Gas shielded welding is a welding method that uses inert gas or active gas to protect the welding area. Common gas shielded welding methods include argon arc welding and argon shielded welding. Gas shielded welding can effectively prevent oxidation and hydrogen cracking, with high welding quality, suitable for circular pipes with high welding quality requirements.

    3. Welding joint form
    When welding circular pipes, common joint forms include butt welding, lap welding, and fillet welding.
    Butt welding is the process of aligning the ends of two circular pipes for welding, resulting in high-quality welding;
    Overlap welding is the process of welding the ends of two circular pipes at a certain distance apart, which is suitable for situations where the strength requirements for the joint are not high;
    Corner welding is the process of welding the ends of two circular tubes at a certain angle, suitable for connecting circular tubes in different directions.

    4. Selection of welding equipment
    When selecting the welding method for circular pipes, it is also necessary to choose suitable welding equipment according to the actual situation.
    Common welding equipment includes manual arc welding machines, gas shielded welding machines, submerged arc welding machines, etc.
    Different welding equipment is suitable for different circular pipe welding methods, and selecting the appropriate welding equipment can improve welding efficiency and quality.

    5. Welding process control
    When welding circular pipes, it is necessary to strictly control the welding process, including parameters such as welding current, welding speed, and welding temperature. Reasonable welding process control can ensure welding quality, avoid the occurrence of welding defects, and improve welding efficiency.

  • Which Is Stronger Round Pipe Or Square Tubing?
    Under the same cross-sectional area, square tubes are usually stronger than round tubes. The cross-sectional shape of square tube is more regular, processed more finely, and assembled more firmly. Therefore, at the same size, the structural strength of square tube is greater and more stable than that of round tube. In addition, the four corners of the square tube are connected by welding, making it structurally stronger.

    Comparison of structural strength

    The strength of square and round pipes mainly depends on their resistance moment (W), which is their ability to resist bending. Generally speaking, square tubes have a greater resistance moment than circular tubes, so they perform better in terms of bending resistance.

    Differences in application scenarios

    In the field of architecture, square structures are widely used because they do not require consideration of toughness, as buildings are stationary. However, in vehicle manufacturing, circular pipes are more common due to their good elasticity and ability to better absorb impacts and vibrations. ‌

  • How Is Round Tube Measured?
    The measurement of circular pipes requires the use of some tools, including vernier calipers, tape measures, micrometers, roundness measuring instruments, and other tools.

    Vernier caliper: used to measure diameter or length. The size of the circular tube can be accurately read through the scale on the caliper.

    Micrometer: used to measure wall thickness. The size of the circular tube can be accurately read through the scale of the micrometer or the screen display.

    Tape measure: commonly used for measuring length. Choosing a tape measure with a locking device can facilitate single person operation.

    Roundness measuring instrument: It can measure the roundness of a circular tube with a certain degree of accuracy and is suitable for situations that require high precision.

  • How To Bend Round Pipe​?
    There are several methods for bending round pipes, including manual bending of round steel pipes and mechanical bending of round steel pipes.
    Manual Bending Of Round Steel Pipes
    Firstly, use a steel ruler or tape measure to measure the position and angle that needs to be bent, and then use pliers to fix the round steel pipe in place.
    Secondly, when using tools with longer force arms (such as pipe clamps) to bend round steel pipes, attention should be paid to controlling the force and speed to avoid excessive deformation and warping.
    Thirdly, after the round tube is bent, it is necessary to use inspection tools with good smoothness to check the bent part, ensuring that the bending angle and radius meet the requirements and there are no cracks or fissures.
    Mechanical Bending Of Round Steel Pipes
    1. Preparation: Place the round steel pipe to be processed on the workbench of the pipe bending machine, and adjust the appropriate processing parameters according to the pipe diameter and bending radius.

    2. Clamping: Clamp both ends of the round steel pipe in the machine fixture to ensure that it is firmly fixed.

    3. Start processing: Switch the machine's working mode to bending mode, turn on the motor, and operate the machine to bend the round steel pipe.

    4. Inspection: After completing the processing, it is necessary to carefully check whether the bent part of the circular tube meets the requirements, including the bending angle and radius, and whether there are any defects on the surface.
