The select bedding and backfill material will be included in the cost 4 of the installed pipe. 5 Where unclassified excavation or borrow material meets the requirements for select 1.02A Single Wall HDPE Pipe Place and compact backfill in layers to the meet the requirements of Table 1. Pipes laid in parallel installations require the same backfill support. Place and compact initial backfill in layers around pipe and at least 6 (150mm) above the crown as shown in Figure 1.

For the less rigid commonly used pipes such as SDR35 PVC pipe and Corrugated HDPE pipes, etc, the backfill and compacting operations must be done with more caution as damaging the pipe below can happen quickly and can go unnoticed.

Concrete and Flexible Pipe Installation Considerations

In this example HDPE pipe only contributes 5% whereas RCP contributes 90% of the structural strength of the soil/pipe system. Therefore, post installation inspection is imperative to ensure the constructed flexible soil / pipe system was properly built.

HDPE pipe safely handles pressurized natural gas and wont leak due to its heat fusion joining. WL Plastics HDPE pipe meets and exceeds all of the testing requirements per Code of Federal Regulations (CFR) 49 Part 192 and ASTM HDPE Pipe Claims on Internet Not Grounded in FactBackfill requirements are also greater for HDPE pipe, normally a minimum of one foot above the top of the pipe versus support only to the springline for RCP. In many cases, wider trenches are required to provide proper side support for HDPE pipe. These additional backfill material requirements, along with the additional compaction and

The most durable pipe on the market. Thanks to its engineered structure and balance of strength and ductility, you dont have to baby our pipe during installation like PVC. Better yet, it offers unmatched flexibility. HDPE pipe can be bent up to radius 25X the nominal pipe diameter. ISCO Industries Total Piping SolutionsISCO is a family-owned, total piping solutions company with more than 30 facilities in the United States and Canada. ISCO offers custom high-density polyethylene (HDPE) fabrication and inventories large stockpiles of pipe, including a large supply of HDPE pipe, usually within a Inspection Manual For Pipe - IN.govUnder each pipe type , the pipe materials that are required areindicated. These sheets also indicate the pipe material abbreviations which are used throughout construction in plans and the proposals (Figure 1-1). When pipe is listed by type, the Contractor may use any pipe material that meets the requirements of that type. If the item

Pipe Bedding and Backfill

Rigid pipe is designed to transmit the backfill load on the pipe through the pipe walls to the foundation beneath the pipe. The pipe walls must be strong enough to carry this load. A line load at the top and bottom of a pipe is the worst possible loading case. If the load can be distributed over a large area at the top and at the bottom of the Polyethylene Pipe Embedment Materials HDPE Trench The favorable characteristics of these type soils, or in combination, lead many designers to select these materials when they are readily and economically available. Maximum aggregate size of Class I and Class II materials when used next to the pipe (i.e., bedding, haunches and initial backfill) should be compatible with the pipe size.

The backfill should be placed evenly on both sides of the structure and advanced along the pipe length at th e same rate to avoid differential loading. At a minimum, larger, multiple barrels and more critical structures should have stone or a uniform graded material, not larger than ½ inch in size, placed for the initial 1.5 to 2 feet up the pipe elevation or to the spring-line elevation of the pipe.
