When rehabilitating a sewer, it’s important to reconnect laterals after the relining of sewer pipes. A contractor relies on the right tools to get the job done fast. A lateral cutter is exactly what is needed to take care of new liners in different types and sizes of pipe. Having gone through extensive changes over the past few decades, the remote controlled unit makes the job easier for the professionals doing it.
How It Was Done in The Past
In the past, pipe relining was awkward. It required a liner system that used short sections of pipe that were pushed into place until a professional reached the first lateral. Laterals were then pre-measured and cut before additional sections were driven in from the other side. This inefficient way of relining pipes caused people to question the process. What was needed was a remote-controlled cutter that could travel into a small space and have the type of reach that got the job done quickly.
Big Advancements in Cutting and Grinding Pipes
Soon air or hydraulic-driven cutters and sewer inspection cameras made their debut. Rather than simply push pipe into place, the tools could cut or grind the pipe and solve issues involving mineral deposits, break-ins, and hammer taps. Once that task was complete, professionals were required to find the lateral in the relined pipe. This required precise measurements.
Pre-Measuring Pipes Accurately Before Pre-Inspection
The standard way of pre-measuring included either dragging the cutter through a line or marking a separate line on the pipe. The latter gave more leeway by allowing several lines to be pre-measured before pre-inspection. Precisely-cut laterals using lateral reinstatement cutters is well worth the time spent guaranteeing their accuracy.
To achieve this, the cutting head is placed on the center of the lateral in a relined pipe. Then, the camera is backed 3-4 feet away. A hole is punched and the lateral is drained. The actual cutting occurs when the cutting heads grind liner material. Large heads are easiest to use because they produce a cleaner edge.
How the Cutter Works in the Mainline
When the cutter is inserted into a mainline, it moves toward the lateral connection based on the measurement given. It then makes a hole to relieve accumulated flow and helps remove the lining material left over so that the professional is able to reconnect the lateral. Then the pipe is cut properly.
Reinstatement cutters make fast work out of big tasks. Choosing the right head makes the biggest difference as it doesn’t require additional sanding like it does with saw-toothed heads. Expert cutters know this and work with the lateral cutting tool that they most prefer. This makes cutting pipes precise and efficient.
Any time a lateral needs to be cut, a reinstatement cutter is used. It’s the preferred tool of professionals who work on relining pipes. Thanks to the advancements made in technology, it’s not as difficult of a process as it was in the past. That’s a relief for both the person cutting the pipe and the person the pipe is being cut for.
