The calculation of the bending radius for steel conduit depends on two factors: typically, the largest diameter or thickness and the hardest cable determine the maximum allowable minimum bending radius; the available installation space determines the allowable bending radius (in cases where the steel conduit installation space is limited); the method for calculating the bending radius: Cable: The bending radius for domestic cables is about 8-10 times their maximum outer diameter; for imported cables, it is about 6 times their maximum outer diameter; Oil Pipe: The bending radius for oil pipes is about 12 times their maximum outer diameter; Water and Air Pipes: The bending radius for water and air pipes is about 10-12 times their maximum outer diameter; Actual Installation Height HL: The bending radius R ≤ (HL-H)/2, where H is the external height dimension of the steel conduit.
How to determine the internal dimensions of a steel cable chain?
The quantity, type, and diameter of cables, gas tubes, hydraulic hoses, etc., determine the internal dimensions and distribution of steel chain conveyors.
Firstly, ensure the internal distribution of the load in the drag chain is reasonable and even: including even weight distribution and reasonable space distribution.
If it's a single load and there's only one, sufficient space is enough.
If you have different loads such as hydraulic pipes, water pipes, air pipes, oil pipes, and cables, it's best to separate them with vertical partitions.
If there are a large number of the same type of loads with significant diameter differences, it's also best to separate them with vertical partitions.
If there are multiple layers, horizontal partition plates can be used to separate them in the height direction.
Next, ensure that the load can move freely within the conduit, preventing any entanglement during arrangement.
Then, based on the load arrangement, calculate the internal height and width: Generally, the internal width and height of the steel conduit chosen are 1.5 times the maximum height and width of the load arrangement.
Finally, decide whether to choose a fully enclosed steel conduit based on the usage environment of the steel conduit (generally, in environments with larger dust particles or more severe conditions, to better protect the load, a fully enclosed type of conduit can be selected).
