What really sets us apart here at DYS Pipe Sales is our innovative centrifugally cast inner molds! Not only are they  made of a  super high-strength carbide alloy, but being that they are centrifugally cast this allows you to safely cut and weld the pipes to any length necessary. Unlike most other dual wall pipes, DYS pipes do not require any special procedures to cut and weld without compromising the molecular structure of the pipe. Which is a huge advantage for anybody that owns a concrete pump and has ever had an issue with down-time due to waiting on pipe kits. Often times after these pipe kits show up with incorrect or missing pieces after weeks of down time. That will no longer be in issue.
