  • Tractive force design for self-cleansing of sanitary sewers

    The new edition of the WEF FD 5/ASCE MOP 60 manual recommends use of the tractive force approach for self-cleansing design of gravity sanitary sewers. The tractive force approach is a major improvement in designing gravity sewers to achieve self-cleansing. This approach results in a self-cleansing slope value, Smin, for the combination of sewer diameter, design particle size, d, and design ...

  • Sanitary Fittings for Plastic and Polypropylene Pipes

    Fittings for metal-plastic pipes have the same function as fittings for metal pipes. To connect them to the pipes, a collet is used. They can also be transitional from a collet to a threaded joint, for joining metal-plastic pipes and metal pipes. One of the most reliable connections for metal-plastic pipes is a press connection (press-fitting compound). It is achieved by ...

  • Sanitary Butterfly Valve Principle of Work

    Sanitary butterfly valve is a type of pipeline fitting in which the locking or adjusting element has the shape of a disc that rotates around an axis that is perpendicular to or at an angle to the working fluid flow direction. Also, these devices are also called turning shutters, airtight valves, and damp valves. The disk shutter can be used to control the flow of liquid, gas ...

  • Comparing the utility of decision trees and support vector machines when planning inspections of linear sewer infrastructure

    Closed-circuit television inspection technology is traditionally used to identify aging sewer pipes requiring rehabilitation. While these inspections provide essential information on the condition of pipes hidden from day-to-day view, they are expensive and often limited to small portions of an entire sewer system. Municipalities may benefit from utilizing predictive analytics to leverage ...

  • Installation Steps of Sanitary Ball Valve

    The sanitary ball valve uses a special molding process to allow a dense sealing surface to achieve zero leakage. Its sphere and shank are fused as one to remove the valve stem from pressure due to pressure changes within the possibility of pressure pieces and, therefore, achieve the fundamental guarantee of safety. It uses a full metal hard welding process that is resistant to strong corrosion. ...
