A good way to distinguish the advantages and disadvantages of plastic drag chains
The thickest cable, oil pipe, gas pipe, water pipe, etc. in the bridge type drag chain shall be selected as the reference height, and the height space of at least 10% shall be used as the inner height Hi of the drag chain In case of overlap, the actual height after overlap is taken as the reference height; The inner width of some cables, oil pipes, gas pipes, water pipes, etc. that are thicker shall be selected, and the sum of their outer diameters shall be used as a reference for the inner width of the drag chain.

The use of steel drag chain originated in Germany
Reinforced nylon is selected as the main material of plastic drag chain, which has high pressure and tensile load, good high elasticity, toughness and wear resistance, flame retardant, stable high and low temperature performance, and can be used outdoors. The outer height, inner height and pitch of the same series of plastic drag chains are the same. The internal width and bending radius R of the drag chain are also different. The unit chain link is composed of left and right chain plates and upper and lower cover plates. It can be opened and disassembled easily without threading. After the cover is opened, the cable, oil pipe, air pipe, water pipe, etc. can be put into the drag chain. Due to the limited bending radius of various plastic drag chains, a complex number of pipes are placed on a unified support plate. If you select a single bend radius, some pipes may be damaged. You can choose to install drag chains with different bending radii. The compound cutting of wire pipe not only effectively maintains the damage caused by pipe friction, but also maintains labor safety.
