The pipelines produced by WLLHOT have obtained qualification reports from multiple national quality inspection units worldwide.

PE-rt（3-layer oxygen barrier）
High performance: the pipeline has excellent high temperature resistance, pressure resistance and aging resistance, and can operate stably for a long time to ensure smooth water flow and efficient use of energy.
Safe and reliable: The pipeline is made of environmentally friendly materials, non-toxic, odorless, and in compliance with global safety standards and regulations. At the same time, the pipeline has reliable connection technology and sealing performance, effectively preventing the risk of leakage and rupture. Strong durability: The pipeline has a long service life and can maintain stability under various environmental and climatic conditions. Its three-layer oxygen blocking structure can effectively prevent oxygen from entering the interior of the pipeline, thereby extending the service life of the pipeline and reducing maintenance costs.
Convenient installation: The pipeline adopts standardized production processes and connection methods, making it easy to install and configure. In addition, the pipeline also has good flexibility, easy transportation and bending, and is suitable for various complex installation environments.
Environmental sustainability: WLLHOT is committed to sustainable development, and its PE-Xa pipeline is made of recyclable materials, helping to reduce its impact on the environment. In addition, energy-saving technologies and measures to reduce waste emissions are adopted in the production process of pipelines.

PE-xa
Pressure resistance: The WLLHOT Weierhead PE-XA tube has excellent pressure resistance and will not rupture or deform even in high pressure environments.
Heat resistance: WLLHOT, after years of research and development, PE- × The applicable temperature range of A tube is very wide, and it can be used at temperatures ranging from -40 ° C to 100 ° C, fully meeting the needs of various environments.
Environmental friendliness: WLLHOT ensures no harmful substances during the manufacturing process and poses no harm to human health and the environment. The PE-XA pipe produced is a new type of environmentally friendly pipe material.
WLLHOT's products have characteristics such as high temperature resistance, solvent resistance, corrosion resistance, and extraction resistance.

PE-xa-Al-pen
Composite layer: The aluminum layer of PE-Xa aluminum pipe is composed of high-purity aluminum foil, closely combined with the PE-Xa material layer, which can effectively increase the corrosion resistance and strength of the pipeline.
High temperature resistance: PE Xa aluminum pipes have high heat resistance and can be used for a long time in high-temperature environments without deformation or damage.
Low temperature resistance: PE Xa aluminum pipes can maintain good performance in low temperature environments and are suitable for conveying pipelines in various low temperature environments.
Good processing performance: PE Xa aluminum pipes can be connected through technologies such as hot melt welding, which is convenient for processing and can meet various complex pipeline design and installation requirements.
