| 红白螺旋管简介 |
在钢管外复合红白相间螺旋状塑料硬管，是我们公司的专利产品，也是环保产品，在施工过程中不电焊不油漆。
Steel pipe coated with red and white spiral shaped plastic pipe is the patent of our company.It is also a green product.It does not need electric welding or painting in the process of engineering project. |
本产品有萤光和反光两个系列

特征是中间是钢管，在钢管外包复一层塑料管，该塑料管是红白二色相间，且是螺旋状结构，特点是既保留了钢管的强度又解决了油漆维护的问题，同时又能起到警示作用。塑料管在生产过程中作了防老化处理，且有1毫米的厚度，所以使用寿命长，可达20年上（红颜色也能保持10年左右的时间）无需维护保养，可广泛应用于作护栏、围杆等，在高架二边、道路二边、绿化区域等均可使用，因为有了红白二色，所以能起到警示作用，减少交通事故，也增加了城市色彩。
This product consist of two pipes.The outer one is plastic.The inner one is steel.It has the advantage of hardness and strength of steel.The plastic coating solve the problem of maintenance.It also has the function of warning.The plastic has been treated by special process to prevent it from ageing.The thickness of the plastic is 1mm.It can used over 20 years(The red colour keeps about 10 years)without. |
考虑到环保及将来的回收利用，本产品的联接方式不采用传统的焊接法，而是采用联接体夹紧法，这样施工文明、方便、干净，若干年后可卸下剥去外层塑料，钢管可重新使用。
Concerning the environmental protection and the plastic recycling,we don't apply welding to join two pipes.Instead,we use a kind of instrument to fasten two pipes.The work is clear,clean and convenient.After many years,the plastic pipe can be removed away and steel pipe can be reused. |
