This catalog introduces a variety of pipes and fittings in different shapes, along with examples of construction for various applications. It also covers fusion connections and mechanical connections as methods for connecting pipes and fittings. You can also check the tool rental service and methods for transporting and storing pipes, which will be helpful for product selection and construction method considerations. 【Featured Products】 Pipe Products ■WED ■WE ■WEETDA/WEETA ■GNGWDA/GNGWA ■WNG/WEETS ■PXE ■GNGAR ■GNGRT Fitting Products ■Various Fitting Products ■EF Fitting Connection ■Butt Fusion ■Connection Short Pipe Quick Reference ■Discharge Manhole Connection Diagram ■Mechanical Fitting Others ■Tool Rental ■Properties of Polyethylene ■From Delivery to Construction *For more details, please refer to the PDF document or feel free to contact us.

GNGRT is an insulated pipe primarily used for hot springs and hot water. Nominal diameter: W25 to W250S Maximum operating temperature: 80°C 【Features】 ○ The conduit is made from high heat-resistant polyethylene, which has characteristics such as heat resistance and chemical stability. ○ The use of EF sockets made from high heat-resistant polyethylene eliminates concerns about corrosion, similar to traditional metal fittings. ○ It is a long pipe that has undergone consistent processing for insulation, installation, and corrosion prevention within the factory. ○ Pipes with a nominal diameter of 100 or less can be delivered to the site as long-length pipes (tab-wound). ○ The introduction of long-length pipes allows for labor-saving in construction and shortening of construction periods, leading to cost reductions. ○ The long-length pipes are highly flexible and can be extended while bending. ○ They are ideal for exposed piping in mountainous areas and for soft ground such as marshes and reclaimed land, and they also excel in earthquake resistance. ○ The outermost layer is coated with low-density polyethylene containing carbon black, which provides excellent weather resistance and corrosion resistance.

Polyethylene pipes have become widespread, particularly in water supply and drainage systems, due to their long-term reliability and seismic resistance, and an expansion of market share is expected in the future! 【Features of MESCO Pipes (High-Density Polyethylene Pipes)】 - The use of long pipes allows for labor-saving construction and a reduction in construction time, demonstrating high cost performance. - By adopting a composite structure, they can be used under high internal pressure. - They are highly flexible, strong against earthquakes, and can be installed along the terrain while bending. - They have excellent weather resistance, making them recommended for exposed piping such as bridge installations. - A wide range of large-diameter pipes up to a nominal diameter of 1,500 mm is available! They can also be used for agricultural water and rainwater drainage applications. 【MESCO's Joint System】 - EF Joint Method: Allows for easy and reliable connections / Stable fusion quality in a short time / Can be installed in narrow spaces. - Automatic Butt Fusion Method: Capable of large-diameter butt fusion (with domestic achievements up to a nominal diameter of W1500) / Integration through thermal fusion enables reliable construction.
