many people have questions when they come into contact with PE pipes - does PE pipe have steel wire? In fact, this question cannot be answered with a simple "yes" or "no", but first clarify the different types of "PE pipe".
First of all, ordinary PE pipe (pure PE pipe) does not contain steel wire. The full name of PE pipe is polyethylene pipe, which is made of food-grade polyethylene resin and is made by extrusion molding. It is characterized by good flexibility, corrosion resistance and light weight. It is common in civilian water supply and drainage, farmland irrigation, low-pressure gas transportation and other scenarios - such as tap water pipes in residential areas, watering pipes in rural areas, mostly pure PE pipes, which are smooth to the touch and cannot see steel wire in section.
But why do some people ask "PE pipe with steel wire"? Because of the existence of "steel wire reinforced PE pipe", which is an enhanced derivative of PE pipe. This type of pipe will add a steel wire layer to the polyethylene material (usually a steel wire mesh skeleton or a steel wire winding structure), the purpose is to improve the pressure-bearing capacity and rigidity of the pipe. For example, "steel wire mesh skeleton plastic composite pipe" is a typical representative: it is woven with high-strength steel wire into a mesh as a skeleton, and the inner and outer layers are wrapped in polyethylene, which not only retains the corrosion resistance advantages of PE pipe, but also can withstand higher working pressure (such as high pressure above 1.6MPa). It is often used in scenarios that require high pressure such as long-distance water supply, industrial wastewater transportation, and oil field water injection pipelines.
In simple terms, ordinary PE pipe = pure polyethylene without steel wire; steel wire reinforced PE pipe = polyethylene + steel wire layer, which is a "reinforced version" of PE pipe. The core difference between the two lies in the pressure-bearing capacity and use: if it is an ordinary household or low-pressure scene, pure PE pipe is enough; if you want to transport high-pressure fluids (such as factory process water, cross-town water pipes), you have to choose reinforced PE pipe with steel wire.
So, next time you ask "PE pipe with steel wire", you can answer like this: not all PE pipes have steel wire - ordinary ones do not have, and high-pressure ones are required. When choosing, look at your own usage scene first, and then choose the corresponding type.
