【Features】 - Made of non-corrosive all polyethylene, suitable for humid environments. - Expected lifespan of approximately 30 to 50 years, contributing to longevity. - Compared to rigid PVC pipes at about 53kg/m, the EP sleeve weighs about 17kg/m, significantly improving the efficiency of transportation and installation work. <Specifications> (This product is referred to by its inner diameter) - EP-600 Inner diameter: 600 / Outer diameter: 700 (mm) Reference weight: approximately 17kg/m * EP-700 Inner diameter: 700 / Outer diameter: 816 (mm) Reference weight: approximately 23kg/m * EP-800 Inner diameter: 800 / Outer diameter: 938 (mm) Reference weight: approximately 29kg/m [Standard manufacturing length: Minimum 300 to maximum 1900 mm] ■ Only for EP-600, we also accept manufacturing lengths exceeding L=1900mm. Please consult us in advance ■ Note 1) The allowable tolerance for the inner diameter of the pipe is ±1.5%. Note 2) The cutting tolerance for the pipe is manufacturing length -5mm to 0mm. Note 3) * Sizes are not part of regular stock items. Please confirm the manufacturing lead time in advance. ▲ Please consider the reinforcement of the sleeve pipe's internal space based on the concrete pouring speed, pouring height, mouth diameter, and beam width at each construction site before use ▲

EP-Sleeve

"Are the beam height and beam width of buildings trending towards extension?" - Responding to high-rise and large space developments - Evolution of seismic and vibration control technologies - Diversification of building uses - Securing equipment space These are said to be the possible factors, but on the other hand, recent construction sites are facing numerous challenges such as labor shortages, aging workforce, and a lack of skilled workers. We urgently need to achieve "labor-saving" and further realize "manpower reduction" by proposing the "lightweight" design of human passage (human access) sleeve materials. "Lightening the burden on the site with technology and ideas!" ＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝ ■ We also offer "labor-saving products" for electrical equipment, including underground beam sleeves ■ 'Waterproof sleeve for underground exterior walls "Pipe-In-Sleeve (abbreviated as PIS)"' "Labor-saving construction for underground beam penetration! Ensuring the waterproof performance of buildings!" For underground exterior wall sections, we apply "waterproof treatment" in advance at the factory to the PVC sleeve and the FEP outer space, delivering it as prefabricated units. This eliminates cumbersome tasks on-site, and after installation, it requires only "joint connections." It ensures stable waterproofing! Achieving work efficiency and "labor-saving" for flood prevention and waterproofing. Please download from the related catalog.
