For the bending operation of RMC conduit (Rigid Metal Conduit), it is necessary to combine tool selection, operating specifications, and material characteristics. The following is a professional operation guide for organizing comprehensive search results:

‍

Advantages and disadvantages of the applicable scenarios of the method

1. Manual bending method for small-diameter pipes, simple bending, low cost, flexible operation, low precision, and easy deformation

2. The pipe bending machine method requires high efficiency and uniform bending on a large scale or with high precision, and the equipment cost is relatively high

3. Hot bending method for special shapes or hard pipes to improve flexibility and reduce the risk of fracture requires temperature control, and the operation is complex

4. The mold method for mass production has high consistency in fixed shapes, beautiful finished products, and high customization costs for molds

5. Precautions and Techniques

Avoid bending after threading

If the cable has already been threaded, bending operation may squeeze the wire and cause damage to the insulation layer. The bend should be completed first before threading.

Material quality inspection

Before construction, check whether the thickness of the pipe wall is uniform, whether there are no cracks or rust on the surface, and avoid using inferior pipe materials.

Special scenario handling

Right angle bend: Use bend springs to assist in forming natural curvature, or use flexible wire technology to ensure smooth threading.

Multiple bending sections: The bending is completed in stages, with a certain distance between each section, to avoid fatigue of the pipe caused by continuous bending
