Gas polyethylene pipe fitting materials "SSB Series"

Gas polyethylene pipe fitting materials "SSB Series"

Branching out from various existing pipes to polyethylene pipes is speedy and economical!

The "SSB Series" is a gas polyethylene pipe material that allows for easy direct perforation of existing low-pressure piping and branching off of PE pipes. It combines the functions of a chip recovery device and a no-blow shutter device, featuring a transition structure with a pre-connected PE short pipe on the branching side. This improves workability and efficiency, significantly reducing costs. Additionally, the excavation area is about one-third compared to conventional methods, which also reduces environmental impact. 【Features】 ■ Allows for easy direct perforation of existing low-pressure piping and branching off of PE pipes ■ Transition structure ■ Improved workability and efficiency, leading to significant cost reductions ■ Excavation area is about one-third compared to conventional methods, reducing environmental impact *For more details, please refer to the PDF document or feel free to contact us.

Installation Guidelines for Stainless Steel LOKRING Fittings

Installation Guidelines for Stainless Steel LOKRING Fittings

We will introduce the construction guidelines for LOKRING pipe fittings made of 316L stainless steel.

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.
