Polyethylene Encasement Tubing

TRUULL POLYETHYLENE ENCASEMENT TUBING protects metallic pipe in corrosive soils. The tubing is slipped over the pipe, extended and taped. An overlap of approximately two feet should be fi gured in calculating the total polywrap required. For example, about 20 feet of polywrap is required for each 18 foot length, or 22 feet for each 20 foot

DuroMaxx Steel Reinforced Polyethylene Technology

loss of pipe stiffness greater than 30% for a non-reinforced profile wall polyethylene pipe. Steel reinforced DuroMaxx pipe loses less than 1% of its stiffness under the same conditions because the steel provides the pipe stiffness, not the PE plastic. As a result, DuroMaxx can be twice as stiff as non-steel reinforced HDPE pipe.
