Distinguish: ceramic, asbestos-cement, concrete, reinforced concrete, wooden, plastic, from porous materials (plastobeton, keramzitosteklo, etc.) polyethylene (from polyethylene of low pressure of PND) drainage pipes. Recently the two-layer polyethylene drainage pipes possessing a uniform structure, high corrosion resistance and durability are most widespread. Stack drainage pipes end-to-end the friend, to the friend connecting special couplings. Drainage pipes have punched openings (perforated or slot-hole openings) through which water arrives.
