Solutions to the challenges of piping welding in steel mills.

There are many narrow spaces in the steel mill, such as "trenches," making welding work on piping difficult. Many facilities have pumps, electrical wiring, hoses, and fittings nearby, requiring protective measures for hot work, which takes time. The "downtime" until the equipment is restored leads to losses for the steel mill. In particular, hydraulic piping is easily affected by temperature, pressure, and vibration, which can cause leaks.
By using Lokring fittings as an alternative to welding, access to narrow spaces is made easier due to the shape of the specialized tools. Since no open flame is used, protective measures against fire are unnecessary, reducing fire risk and significantly improving safety. The installation does not require special skills and can be completed in a short time, thereby reducing equipment downtime, enhancing productivity, and significantly lowering costs. Lokring fittings comply with ASME B31 and have performance comparable to welding, making them suitable for use under harsh conditions, thus solving many challenges associated with piping welding. I would like to introduce some representative cases. I hope this will be helpful to those involved in the reference steel mill.
