LJ Welding Automation provides top quality, heavy-duty pipeline construction equipment for both pipeline building and maintenance. LJ’s pipeline construction equipment is engineered for applications such as horizontal directional drilling (HDD) crossings, pipeline construction, and offshore firing lines. Pipeline rollers and pipeline cradles ensure a quick and efficient welding process, offering faster installations than do traditional processes and better worker safety. We build LJ’s pipeline construction equipment for heavy-duty use and design it to be reused repeatedly.
LJ's standard pipeline rollers are trusted for pipeline construction for pipe ranging from 2" to 72" outer diameter (OD). With full engineering and custom fabrication ability, LJ can design and build rollers to suit any unique project.United States of America CASE STUDY: HDPE WATER PIPELINE INSTALLATION WITH POLYURETHANE ROLLERS Canada CASE STUDY: 6″ OD NATURAL GAS TIE-IN APPLICATION WITH PIPELINE ROLLER RENTAL Canada
Horizontal Directional Drilling (HDD) has become one of the most used methods of installation because it reduces traffic disruption and decreases surface damage.Chile CASE STUDY: TUNNEL INSTALLATION USING HDD PIPE TUNNEL ROLLERS Nigeria CASE STUDY: PIPELINE INSTALLATION FOR RIVER CROSSINGS USING POLYURETHANE ROLLERS
