The piping that is in contact with soil or runs below grade level is called buried or underground piping. In the oil and gas industry, we find frequent use of buried piping mainly for cross-country pipelines where security and safety justify the pipelines to be underground.
Paling Underground Drainage Systems make use of pipes that are both flexible and strong. These versatile products are suitable for all types of sewage and are useful for all building applications.
The term “underground” applies to the piping – both buried or in trenches. The underground system consist of gravity flow drainage system carrying process waste, spillage, reclaimable hydrocarbons, sanitary and storm water, firewater and drinking water system.
terminology and design concepts relating to the underground installation of PE pipe will be fully discussed. This will include fundamental guidelines regarding trench design and the placement and subsequent backfill of the PE pipe. This chapter is intended to assist the pipeline designer in the underground installation of PE piping materials ...
There are four types of AC drainage pipes such as Non-pressure pipes for sanitary sewers, pressure pipes for local water mains, storm drain pipes for carrying storm drains and transmission pipes for use as water mains.

For the standard product range, the nominal pipe diameters (DN) range from 80 mm up to 4000 mm with nominal pressure classes (PN) of 1, 3, 6, 10, 12, 16, 20 or 25 barg and nominal stiffness classes (SN) of 2500, 5000 or 10000 Pa. The table 1 shows Fiberstrong™pipe standard lengths. Table 1: Standard Pipe Length.
Underground Pipe. External damage of underground pipes and polymers can be caused by manufacturer faults, temperature, coating or cathodic protection issues, the activities of organisms such as bacteria or fungi, and soil chemistry (Khajouei et al., 2017).
