Now Available ASTM F-1803(Pro21)
Product Description
"PRO-21" Closed profile pipe is produced by extruding an "I-Beam" type profile which is wrapped onto a circular mandrel providing a continuous tube with a helical heat-welded seam. The result of this process is a pipe of solid wall appearance from the inside and outside coupled with the structural advantages of the "honey comb or I-beam" construction internal to the pipe wall itself. The pipe meets ASTM F794 Closed Profile Pipe and ASTM F1803.
Features and Benefit
- Made of PVC, the entire product is immune to the corrosive acid conditions that result from hydrogen sulfide gas generation in sanitary sewer lines. It is not susceptible to electrolytic corrosion. It is resistant to chemicals typically conveyed in sanitary sewers.
- By putting the structural rib on the inside both the ID and OD are free of ribs. The relatively smooth outside diameter allows easy fabrication of fittings, easy simple tapping with a saddle or Inserta-Tee type fitting and manhole connections with "A-Loc" or other boot type manhole gaskets are confidently made. There is reduced chance of separating joints by movement of a trench box compared to external ribbed pipe.
- Air tight joints bring peace of mind to the installing contractor and on-going financial savings to system owners. System leakage rates of less than 10 gallons per inch of diameter per mile per day are possible with the proper choice and testing of manholes and fittings. Zero leakage from the pipeline itself is also possible with the four fined gasket design which is provided by Diamond Plastics.
- Lighter weight than comparable size concrete pipe, Diamond Plastics closed profile pipe is both easier to handle and reqires less bedding for grade maintenance.
- Increased flow capacity allows downsizing of pipe diameter or reduced slope compared to concrete pipe. Gravity flow applications are designed with a Mannings n = 0.009 whereas pressure applications use a Hazen-Williams C = 150. The smooth PVC surface makes pipe cleaning easy with routine hydro-cleaning equipment.
- Flexible Strength is achieved with the material-efficient internal rib construction. A minimum pipe stiffness of 46 psi is sufficient for most applications - from the deepest sewer and drainage projects ( 40 + feet deep ) to the shallowest irrigation ditch closings ( 2 to 5 feet deep )
