Three Common Questions About Ductile Iron Pipe Gaskets Mcwane Ductile The harder rubber of the heel makes it more rigid and helps hold the gasket in place as the joint is being assembled. the bulb, made of a softer rubber, will compress easier during joint assembly than if it were made of a harder rubber. left gasket is manufactured by mcwane ductile and u.s. pipe. right gasket is manufactured by american. Ductile iron pipe is one of the most widely used pipe materials in north america. the design life is second to no other pipe material due to its robust design. in most soils, di needs no additional corrosion protection. however, polyethylene encasement should be used when the soils on the project are determined to be corrosive to di pipe.
Three Common Questions About Ductile Iron Pipe Gaskets Mcwane Ductile Among the most popular questions are: 1. why is the exterior of ductile iron pipe so “bumpy”? while visually "bumpy," the exterior of ductile iron pipe, if you slide your hand along the surface, feels relatively smooth like a golf ball – texture vs. feel. that's because the texture applied is entirely purposeful and proprietary to each. Gaskets are critical components in your ductile iron piping system. today’s modern push on gaskets comprise different types of rubber compounds, and the development of the push on gasket has proven to be instrumental to the success of the leak free water and sewer joint. 1. for ductile iron applications utilizing tyton® pipe, vales, and fittings made to awwa specifications. 2. in cold weather assembly maintain the temperature of the gasket above 40° f. 3. the socket of the joint should be clean and free of debris or significant corrosion. 4. gasket should be properly seated in the bell socket. 5. A displaced or rolled gasket creating water loss in a ductile iron pipeline is one of the most common errors that occur during joint assembly. to avoid displacing or rolling a gasket and to ensure proper joint assembly, be sure to follow these five easy steps. download.
