3 Must-Have Non-Welded Piping Equipment – Benefits You Should Know Piping solutions are now using non-welded piping technologies because they offer reductions in fabrication and time while enhancing workforce safety. For certain applications, welded systems are no longer applicable or a reliable economic choice. Hose, pipes, and tubes are largely used in the hydraulic industry due to their flexible structure. As the name suggests, non-welded piping equipment and connections unite two hydraulic pipes without using a conventional welding process. This method is commonly used for pipe grooving and threadless fittings in applications like refineries, wind turbines, locomotive/seismic, steel and power plants. Non-Welded Piping Equipment 1. 37º Flare Flange A system based on flaring the pipe ending to 37 degrees and using internal cones and flanges for easy assembly. Both cones have O-rings, attaching the connection together to align flared pipe and cone with each other to provide an elevated seal. It is considered a proven solution for relatively thin-walled pipes. 2. Retain Ring Flange It is useful for heavy wall pipes, which have a machined butt-end face alongside an annular groove on the outer diameter. It is largely utilized for high-pressure and large pipe sizes. Bolt the flanges together and draws retain rings towards the O-ring seal within the connection. Pipe sizes ranging from 1-1/2” through 10” are used with pressure up to 6000 psi. 3. PYPLOK® It is a weldless connection system to join pipes. It is mainly used in the most demanding environments where fire safety and quick and easy maintenance repairs are essential. It is great to use a portable, hand-held tool, compressed onto piping to form a permanent leakproof seal. PYPLOK® couplings are available in stainless steel type 316L, carbon steel, and copper-nickel. Use this connection system to eradicate the extensive need and costs of welding. Installation, repairs, and maintenance can be made easily to minimize the duration of a shutdown. Benefits of Non-Welded Piping
Time-saving – Non-welding piping need only tightening at joints while welding requires extensive surface preparation, welding, and grinding, which saves ample time and energy. Safe – Non-welded technology is safe for assembling pipes. There is no need for obtaining safety permits or evacuating sensitive equipment in the work area. There is no such process hazard as exposure to radiation and disruption of bunkering and tank smearing. Flexible in confined areas – Non-welded piping systems cater to areas where movement is restricted. As it fits joint using fastening or swaging technique, confined areas don’t hinder the installation. Reliable – No need to worry about weld contamination and erosion, which may damage sensitive hydraulic components. There is no problem of stress corrosion, resulting in a longer time span of machinery.
