The size and specifications of cable conduits must comply with design requirements and relevant standards. The test includes the diameter, length, wall thickness, bending radius, etc. of the catheter. Use a bending tester or bending block for testing to simulate the bending of cable conduits in actual use. Bend the conduit within the specified bending radius and observe whether there are any cracks, indentations, or other deformations on its surface, in order to determine whether its flatness meets the standard requirements. For cable conduit joints, sealing tests are required to ensure they do not leak. The testing methods include hydrostatic testing and pneumatic testing, which observe the sealing performance of the joint by applying a certain amount of pressure.

Cable conduits are widely used in fields such as power, communication, petroleum, and chemical engineering. In the field of power, cable conduits are mainly used to protect power cables and ensure the stability and safety of power transmission; In the field of communication, cable conduits are used to protect communication cables and ensure the smooth flow of communication signals; In the fields of petroleum and chemical engineering, cable conduits are used to protect cables in oil and gas pipelines, ensuring smooth oil and gas transportation.
