The Industry lets out smooth neglazurovannye pipes without bells or glazurovannye with a bell and punching on walls. Crock water absorption - no more than 15%, frost resistance - not below 15 cycles. Apply pipes at meliorative works, and also at drainage of the soil basis under buildings and constructions.
Sewer pipes produce from plastic fire-resistant or refractory glin. Form them in the vertical trumpet; 102
pressah, burn at temperature 1250-1300°С before sintering. A surface of pipes outside and inside cover kislotostojkoj with glaze. Sewer pipes should maintain hydrostatic pressure not less than 0,2 MPa. Water absorption of a crock of pipes: no more than 9% for I grade and 11% for II grade. Length of sewer pipes of 800-1200 mm, internal diameter of 150-600 mm. These pipes on one end have a bell. Sewer pipes apply to tap of waste sour and alkaline waters.
