Modern industry needs better piping systems, especially ones that can resist corrosion, connect reliably and be installed efficiently. Thin-walled stainless steel pipe fittings are a good choice because they work well. This paper discusses a new way to make pipe fittings.
Internal high-pressure water expansion molding technology uses high-pressure water to deform and fit the inside of the pipe into the mold, forming the desired shape. This technology has several advantages over traditional methods.
First, this process can make complex shapes, which are often difficult or expensive to make in other ways.
The technology makes sure the fittings have the same wall thickness, which avoids stress concentrations and the risk of them breaking due to uneven wall thickness.
The inner walls of the fittings are not damaged during the molding process. This technology also improves product quality, productivity and reduces labour costs.
Double clamp fittings are a connection method that uses rings on both sides of the expansion kit to secure the pipe joints. Combined with internal high-pressure hydro-expansion molding technology, double clamp fittings can be produced in precise sizes and shapes, ensuring reliable connections and system stability.
Double clamp fittings made by this technology are used in many fields, including building water supply and drainage, gas transportation, and medical gas transportation. They resist corrosion and are easy to install and maintain.
But there are also challenges to internal high-pressure water-expansion molding technology. The equipment and control systems must be precise. Also, different pipe fittings need different process parameters to ensure good quality.
This technology shows great potential for making thin-walled stainless steel double press-type fittings. As technology improves, we believe this technology will become more important in future piping systems.
