•PE lay flat hose, also known as polyethylene lay flat hose, has been an important tool for the transportation of water and other fluids in various industries for several decades. The development of PE lay flat hose can be traced back to the early 1960s.

•Initially, PE lay flat hose was made using low-density polyethylene (LDPE). This material was chosen due to its flexibility and ease of manufacturing. However, LDPE hoses were prone to kinking and folding, which limited their usefulness in many applications.

•In the 1980s, high-density polyethylene (HDPE) became available, which allowed for the development of more robust and durable PE lay flat hoses. HDPE hoses were resistant to kinking and folding, and could handle higher pressure and flow rates.

•In the 1990s, the use of reinforced PE lay flat hoses became more widespread. These hoses featured an internal reinforcement layer, typically made of polyester, which added strength and durability. Reinforced PE lay flat hoses were capable of handling even higher pressures and flow rates, and were used in applications such as irrigation and firefighting.

•Today, PE lay flat hoses continue to be an important tool for fluid transportation. Modern PE lay flat hoses are made using a variety of materials and manufacturing techniques, which allow them to be tailored to specific applications. For example, hoses may be reinforced with materials such as aramid or steel wire, or may feature specialized coatings for improved chemical resistance.

•In recent years, advancements in technology have also led to the development of lay flat hoses that are lighter, more flexible, and easier to handle. These hoses are designed for applications such as firefighting, where fast deployment and ease of use are critical.

•Overall, the development of PE lay flat hoses has been driven by the need for a reliable and efficient method of fluid transportation in a variety of industries. As technology continues to advance, it is likely that we will see further improvements in the design and performance of these important tools.
