TR Flex® is the most widely accepted and installed integrally cast restraint joint system in the Ductile iron pipe industry. Proven as a versatile and easy-to-use item, this joint is flexible, sure, and watertight to and beyond its up-to-350-psi pressure rating while preventing longitudinal separation of the joints, whether installed above or below ground.
Having managed water and wastewater systems for most of my career, I have engaged with interest in the operations of specific water systems. Many times, those conversations have lead into areas beyond the engineering criteria for daily operations and into areas such as customer satisfaction. The great majority of these systems meet all required regulatory quality standards each day. Then why do customers become dissatisfied with the utility? One notable answer: SERVICE.
Polyethylene encasement (polywrap) has been used since 1958 to protect ductile iron pipe from corrosion. It is the most popular, economical, and successful method for protecting pipe from corrosion.
A new advancement in polyethylene encasement called V-Bio® adds additional protection by inhibiting the formation of corrosion cells under the wrap. McWane Ductile added V-Bio® polywrap to its line of products in 2015. Adding a few steps to your pipe installation with V-Bio® is an Iron Strong decision that will benefit your pipeline for generations.
