　　电厂通常是使用双启齿尼龙波纹管的大户，由于电厂的行业特殊对于电线电缆的防护要求更为严格，采购的双启齿尼龙波纹管应具有的耐磨，耐热、耐油、耐酸碱等特性。随着现代化经济的发展，电厂各种设备不断更新，老设备线路的定期检修维护，相比其他行业电厂的双启齿尼龙波纹管需求数量要大很多。所以在购买时需要注意以下几点：

　　1. Look at the appearance: whether the color of the whole coil of double split nylon bellows is consistent, whether the outer wall of the pipe is smooth and flat, whether there are cracks and bubbles.

　　2. 看做工：双启齿尼龙波纹管外管和内管相接的槽口是否平整，有无变形和扭曲。外管两边的切口是否光滑平整（如果这两个切口不够平滑，太过锋利，工人在施工时容易划伤手指，也会对电缆外壁构成危害）。

　　2. Look at the workmanship: whether the notch between the outer tube and the inner tube of the double split nylon bellows is flat, whether there is deformation and distortion. Whether the cut on both sides of the outer pipe is smooth and smooth (if these two cuts are not smooth enough and too sharp, workers will easily scratch their fingers during construction, which will also harm the cable outer wall).

　　3. 看包装：双启齿尼龙波纹管一般厂家在打包出售时只是在管子外层缠绕1-2圈类似保鲜膜样的塑料薄膜。在运输过程中快递转运、搬动、拖拽肯定在所难免，由于包装管子的塑料膜本本身的厚度很薄，任何的移动都可能导致刮烂划伤，对管子外壁也会造成一定程度的损伤。影响使用寿命。建议多缠几卷，或是用编织袋缠绕包装。

　　3. Look at the packaging: the general manufacturers only wrap 1-2 circles of plastic film on the outer layer of the pipe when packing and selling. In the process of transportation, express transportation, moving and dragging are inevitable. Because the plastic film of the packaging pipe is very thin, any movement may lead to scratch and scratch, and also cause some damage to the outer wall of the pipe. Affect the service life. It is suggested to wrap more rolls or wrap them in woven bags.
