1. LONGEVITY ….Many Vitrified Clay Pipe lines installed over one-hundred-fifty years ago are still performing as efficiently as the day they were first installed….. |
|
3. Tight Joints ...Advanced technology has resulted in major improvement in the jointing of pipe. |
|
2. Structural Integrity Vitrified Clay Pipe is a rigid material and is not subject to the problems of deflecting or flattening under load. The characteristics of clay pipe remain constant due to its inherent physical properties….. |
|
4. Corrosion Resistant ….Vitrified Clay Pipe is the only sewer pipe material proven over centuries of use to be resistant to attack by sulfide-generated acid, most industrial wastes and solvents or aggressive soils. The entire wall of clay pipe is chemically inert-providing built-in protection against any disintegration or loss of strength. It does not require any lining or protective coating. |
|
6. Abrasion Resistance ….Rigid Vitrified Clay Pipe, a ceramic material, is virtually unaffected by abrasion because of its hard, thick and dense pipe wall. |
|
5. Good Flow Characteristics …..Vitrified Clay Pipe retains its shape and resists corrosion better than any other sanitary sewer pipe material. It is strong, rigid, chemically inert and immune to gases and acids normally found in sanitary sewer lines……. |
