endobj It is also difficult to repair them.Vitrified Clay Pipe is not often used as pressure pipe, but is widely used in sewerage and drainage for flow at partial depth.The main advantage of vitrified clay pipe is that it is virtually corrosion-free, has a long life, and its smooth surface provides high hydraulic efficiency.Use of vitrified clay pipe under pressure is usually prevented by its low strength in tension and the difficulty of securing watertight joints.The most common joint for vitrified clay pipe is the bell-and-spigot flexible compression joint in which precision mated surfaces are in tight contact with one another.Rubber-sleeve couplings held in place with corrosion-resistant steel bands are occasionally used with a plain-end clay pipe,…but more often the joints of this type of pipe are left open to permit passage of water either into or out of the pipe.Vitrified Clay pipe is most commonly made of 3-ft lengths, but 2, 2.5, and 4-ft lengths can be obtained.Inside diameters vary by 2 inches increments from 4 to 12 inches and by 3 inches increments above 12 inches.Clay pipe in diameters greater than 36 inches is rarely used.Because of the dimension changes, while the pipe is in the kiln, liberal tolerances in all dimensions are necessary.My question is,how many branches we have do from 20 mm dia pipe in a horizontal linesthey serve mostly which purposes , can they be used where pressure is wanted .if i need 50litres of water which pressure head will need to have on the pipe stream 1.

The hydraulic efficiency of an asbestos pipe is high.These pipes are soft from the inside. It means that if you choose a ball valve over a butterfly valve for the same function. These pipes are made from steel sheets.Small pipes have welded joint along the length which is not visible. /Type /XObject /FormType 1 The average age of such pipes is from 25 years to 50 years.These pipes are light in weight. /ExtGState
