Need casing around your pipeline for a bridge crossing? Or below a railroad crossing or a highway? Provide cathodic protection to the pipe by installing TDW’s M-2 Plastic THINSULATOR® pipe insulator between the pipe and casing walls. This will assure no metal-to-metal contact, eliminating corrosion caused by electrochemical activity.
Finish the job with our three-way cradle or concentric support cradle at the casing ends to center the pipe in the casing, followed by our Z-SEAL™ Casing Seal or U-SEAL™ Casing Seal to moisture-proof the inside of the cradle.
