WED pipes are dual-layer pipes made of high-density polyethylene, available in sizes that conform to ISO standards. Nominal diameter: W40 to W350 【Features】 ○ It applies the international standard ISO4427, which originated in Europe, where the penetration rate of polyethylene pipes is the highest in the world. This allows for the use of a wide variety of fittings. ○ Made from black high-density polyethylene with excellent weather resistance, making it suitable for exposed piping. ○ Pipes with a nominal diameter of W100 or less can be delivered in long lengths (tab-wound). ○ The delivery of long-length pipes can reduce labor and shorten construction time, leading to cost savings. ○ Polyethylene pipes are flexible and have excellent seismic resistance.

WEETDA enhances internal pressure strength and suppresses creep by wrapping aramid fibers around a high-density polyethylene double-layer pipe, creating a composite structure. Operating Pressure Nominal Diameter (Conduit dimensions are based on ISO standards.) 〇WEETDA-13.6 1.0MPa W40～W100 〇WEETDAX-13.6 1.5MPa W40～W100 〇WEETDAY-11 2.0MPa Please contact us for details. 【Features】 ○ The use of long pipes reduces labor and shortens construction time, allowing for cost savings. ○ It has excellent flexibility and can be extended while bending. ○ The outer layer is coated with low-density polyethylene containing carbon black, providing excellent weather resistance and corrosion resistance. ○ By using fittings of the same material and applying EF fusion and automatic butt fusion, it creates a highly reliable pipeline with a monolithic structure.

MESCO pipes support "living" in every place from the ground to the seabed. Based on the trust and achievements cultivated over more than 50 years of responding to diverse needs, we strive to improve our technical capabilities in piping lines and are committed to providing "valuable products" every day. Polyethylene pipes, backed by excellent corrosion resistance and flexibility, hold an overwhelming share as piping materials for infrastructure development such as water supply, sewage, and gas in Europe and the United States, particularly within the EU, and have recently gained significant attention in our country as well. **Features of MESCO Pipes** - The use of long-length pipes allows for labor-saving construction and shortened construction periods, demonstrating high cost performance. - By adopting a composite structure, they can be used under high internal pressure. - Their excellent flexibility makes them earthquake-resistant and suitable for construction that follows the terrain. - With outstanding weather resistance, they are suitable for exposed piping such as bridge installations. - We offer a range of large-diameter pipes up to a nominal diameter of 1,500 mm, making them suitable for applications such as agricultural water and rainwater drainage. MESCO pipes provide the optimal products tailored to your needs and usage conditions through a rich lineup, responding to your requests.

Lightweight and highly corrosion-resistant polyethylene pipes offer significant advantages over traditional metal pipes in terms of workability and durability. They have received high praise in infrastructure development focused on seismic resistance, and the trend towards larger diameters is rapidly advancing in the fields of water supply, sewage, and industrial piping. Among these, Mesco pipes provide consistent support from design to construction, demonstrating strengths in the construction technology of large-diameter piping. In particular, in exposed techniques (including bridge attachments), we have established safe and efficient construction methods that consider structural conditions and surrounding environments, thereby building reliable lifelines. Furthermore, installation locations vary widely, including buried, exposed, mountainous, bridge, and underwater settings, achieving high durability and workability even under harsh conditions, contributing to the creation of disaster-resistant social infrastructure. ◆Exhibition Information◆ We will be exhibiting at 'InterAqua 2026'.
