STREET SEWAGE SYSTEM

STREET SEWAGE SYSTEMSPipes and fittings for steet sawage systemsDrainage-sewage problem solution and systemic sewage net construction, respectively, presents one of the primary problems of all urbanized centers; therefore, we find program application of street sewage in drainage pipelines for waste and precipitate waters in households, road construction, bridge construction etc. They are also used in waste water drainage in agriculture, for ventilation purposes, protection and sheathing. They are available in diameters from DN 110 to DN 500 with standardized production lengths according to DIN 8062.MaterialPipes and fittings of street sewage system are of red-brown colour according to RAL 8023 and are delivered with incorporated gaskets, which together with the embracer, enable fast and simple connection.They are produced from hard PVC, characterized by high mechanical resistance to acids and many organic and inorganic substances.It is also resistant to abrasion (wearing) with a high resistance to ageing and external influence. Low pipe weight and high mechanical hardness alleviate transport, manipulation and mounting.PVChardness and stiffness temperature steadfastness hardly inflammable resistance to sediments and bacteria resistance to chemicals StandardStandard in compliance with the requirements of the norm HRN EN 1401.Mounting modeTechnological development in the field of plastic materials has made possible production of a wide assortment of fittings and special parts making possible solutions of all situations regarding PVC pipe mounting in sewage system. Proper mounting of PVC sewage pipes requires uniform basis, i.e. care should be taken at all times to avoid vacancies under pipes and to keep filling between pipes and canal walls uniform and compact. During work on the construction lot, particularly during mounting, pipes shouldnt be dragged over the soil. On the contrary, stones and other sharp objects may cause irreparable damages. Connection is performed on dry principle with the embracer and gasket, achieving absolute impermeability, simplicity and mounting speed. During pipe shortening, the tip of the pipe should always be finely honed to achieve the angle of approximately 30?, alleviating further connection.
