HDSS and HP LOK restrained joint pipe are well suited for bridge applications. Long spans, aerial crossings and pipe on support applications such as creek crossings etc, are accomplished using standard U. Pipe joints such as TYTON JOINT®, HP LOK®, HDSS®, MECH LOK® or Flange Pipe. The following examples show different types of installations and typical joints that are. The Ductile Iron Pipe Research Association (DIPRA) periodically receives requests from engineers and contractors concerning recommendations on the design and/or installation of pipelines spanning waterways, highways, and railroads. Because the variables involved in such installations present. Ductile iron pipe meets, with a wide safety margin, the necessary requirements for transporting drinking and wastewater on bridges. When choosing, the degree of freezing risk must be taken into account, for which we have special coatings that prevent freezing at temperatures well below the water. Has consideration been given to make the crossing using River Crossing pipe or Horizontal Directional Drilling (HDD) with TR Flex pipe?“ For this #IronStrong Blog, we will assume that these options have been examined and that the most effective way to complete the project is to install the piping. Ductile Iron pipe is centrifugally cast in 18- and 20-foot nominal laying lengths. Nominal diameters range from 3 to 64 inches, with a variety of pressure and special thickness classes.
