We will introduce the installation procedure for the 'SS40 and SS-3300 series' that we handle. First, cut the pipe at a right angle and use 120-grit sandpaper to polish the sealing surface in a circular manner, cleaning the surface to remove any scratches. Next, use a Multi-Purpose Gauge (MPG) to confirm that the outer diameter of the pipe is the appropriate size and mark the pipe. Then, select the necessary LOKRING tools for installation, inspect the tools, and ensure they operate correctly. After that, set the fitting at the location marked "INSTALL" and securely install it while operating the tool. Finally, visually confirm that the installation has been done correctly. *For more details, please refer to the PDF document or feel free to contact us.

We will introduce the installation procedure for the 'MAS-3000 series' that we handle. First, cut the pipe at a right angle and use 120-grit sandpaper to polish the sealing surface in a circular manner, cleaning the surface to remove any scratches. Next, use a Multi-Purpose Gauge (MPG) to ensure that the outer diameter of the pipe is the correct size and mark the pipe. If the surface condition of the pipe is poor, apply a thin layer of PST sealant (liquid TFE) as an aid for sealing. Then, select the necessary LOKRING tools for installation, inspect the tools to ensure they operate correctly, set the fitting at the location marked "INSTALL," and securely install it while operating the tool. Finally, visually confirm that the installation has been done correctly. *For more details, please refer to the PDF materials or feel free to contact us.

Introducing the technology of "Elastic Strain Preload (ESP)." During installation, the axial movement of the LOKRING driver on the joint body compresses the body against the pipe surface, initially elastically and then plastically compressing the pipe wall. As resistance to the compressive force on the pipe wall occurs, significant compressive loads develop at the contact area between the narrow sealing section inside the joint body and the pipe surface. 【Features】 - The pipe wall is initially compressed elastically and then plastically. - Significant compressive loads occur at the contact area between the narrow sealing section and the pipe surface. - Plastic deformation occurs on the pipe surface beneath multiple sealing sections. - A permanent seal of metal is formed between the pipe and the joint body along a 360° circumference. - The durability of the connection is enhanced. *For more details, please refer to the PDF document or feel free to contact us.

The "LOKRING fitting" is a piping solution that achieves a high-strength and high-seal connection without welding by attaching the fitting body to the piping and tightening it with a special tool. You can watch the installation of Lokring fittings in a YouTube video. Since Lokring fittings do not use open flames, there is no need for protective measures around the area, reducing the risk of fire and explosion. They can be installed in confined spaces adjacent to walls and ceilings, repair existing piping, and work even when fluids are flowing, allowing for quick and easy installation, which contributes to reduced work time and alleviates labor shortages. 【Features】 ■ Improved safety by connecting piping with high strength through crimping without using open flames. ■ Reduced construction time due to quick installation, contributing to cost savings. ■ Easy installation helps alleviate labor shortages. *For more details, please refer to the materials available for download in the <Download Catalog> section.

In chemical plants and power stations, many "flanged joints" are used outdoors. Flanged joints are essential for connections with valves and equipment. However, there are many flammable fluid pipes in the surrounding area, and hot work such as welding poses risks, necessitating fire protection measures. Additionally, rainwater can infiltrate the gasket area, leading to corrosion and potential fluid leaks, which can be time-consuming and labor-intensive to inspect. This issue is particularly exacerbated in petrochemical plants and power stations located along the coast, where salt damage further complicates the problem. The 'Lokring joint' provided by E-Piping features a sealing structure (inboard seal and outboard seal) that isolates the main seal from external environments and internal fluids, thereby reducing the possibility of leaks. (Refer to the PDF for more details) **Features of Lokring Joints** - Reduces the possibility of leaks! - Can be installed easily and quickly without using fire! - Contributes to improved safety, reduced labor, and lower overall installation costs! - Usable in areas with risks of ignition or explosion, and can be installed underwater. *For more details, please download the PDF or contact us directly.*
