Jindal Multi Layer Composite (MLC) pipes being produced with IS:15450 standards at its state of the art manufacturing unit at Dehradun, Uttaranchal, India.Jindal MLC Pipes combine the advantages of metal and plastic pipes and eliminate the disadvantages of both materials at the same time. The aluminum core is absolutely diffusion tight and reliably prevents oxygen or gases from permeating into the pipe. It compensates and reduces snap-back forces and heat expansion with changes in temperature. Jindal MLC Pipes consist of an overlapped aluminum core with an inner and outer layer of polyethylene - PE. All the layers are permanently bonded together by intermediate adhesive layers. The aluminum thickness of Jindal MLC pipes has been selected to meet compressive and flexural strength requirements
