Lightweight polyethylene personnel access EP sleeves support shortening construction timelines!

In the construction industry, shortening construction periods is a crucial issue directly linked to cost reduction and efficiency. In particular, the installation of access openings is one of the factors that affect the construction schedule due to the time and effort required. EP sleeves, being lightweight, facilitate transportation and installation, contributing to a reduction in work time. 【Usage Scenarios】 ◆ For access openings in water pit partitions of buildings and various structures! - Ensures high load-bearing performance with polyethylene pipes. - Reduces work burden with lightweight polyethylene sleeves. - Provides corrosion resistance measures in underground pits and water areas. 【Benefits of Implementation】 ◆ Proposals for labor and manpower savings! - Reduces the burden on workers - Cost reduction through shortened construction periods - Improved safety *For more details, please request a catalog through "Contact Us" or view the PDF data via "Download."

basic information

**Features** - High pressure resistance: Strong against impact and external pressure, excellent flat strength - Lightweight material: Lighter than rigid PVC pipes, contributing to transportation and work efficiency - Rust-resistant: Made of high-density polyethylene, ideal for installation in wet areas - Cold and chemical resistant: Resistant to extreme cold and chemicals **Our Strengths** We provide products that contribute to solving challenges at construction sites. Please feel free to contact us. **Specifications** (This product is based on nominal 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 [Manufacturing length: Minimum 300 to Maximum 1900 mm] 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. 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 for each construction site before use.**

Applications/Examples of results

Are the 'beam depth and beam width of buildings trending towards extension'? - Response to high-rise and large space development - Evolution of seismic and vibration control technology - 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'! Furthermore, to realize 'human-saving' beyond that, we propose the 'lightweight' of human passage 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 for the construction of underground beam penetration! Ensuring the waterproof performance of buildings!" For the underground exterior wall section, we apply 'waterproof treatment' in advance at the factory to the PVC sleeve and the surrounding space of the Eflex (FEP), delivering it as prefabricated. No cumbersome work is required on-site; after installation, it is basically "only joint connection." Stable waterproofing is guaranteed! Work efficiency is improved, achieving 'labor-saving' for flood prevention and waterproofing. Please feel free to download from the related catalog.
