In summer, there will be more rainy days. Thus water discharge becomes an important work. Generally, PVC hose and metal hose are both good for water discharge. However, some people think the metal hose is much heavier than PVC hose. Because in their opinion, metal is heavier than plastic. But in fact, it’s not that exactly. Besides material, many other factors affect the weight, such as wall thickness.
Is metal corrugated hose heavy?
In fact, different size, thickness and other specs cause different weight. For example, DN50 and 0.25mm thick metal hose weights about 0.45kg/m. While it’s 0.55kg/m of DN60 with the same thickness. Besides, DN50 and 0.28mm thick hose weights 0.5kg/m. These 3 types are also the most used specs.
How to test prestress metal corrugated hose
The test is mainly to check the appearance, diameter, stiffness and bend performance. There is also state standard JG 225-2007 for it. Besides the hose itself, the standard also stipulates the classification, requirement, test method, pack and transfer. As for the material, it requires the material is zinc coat or mild steel.
In another hand, keep the metal corrugated hose surface clean is necessary. Besides, there should not be any oil, rust and hole in both internal and external surface. Only this we can say it’s a standard. More important, there will not be quality or maintain problem in the future use. In general, you need to check it strictly after the production. Only the qualified products can be sold.
