PE pipes can be jointed using butt and electrofusion techniques or using mechanical fittings. Polytheylene products including polyethylene pipe , PE Fittings and PE Manholes . In the past 50 years we have had significant progresses in production of PE pipes and PE Fittings and PE Manhole which are now an appropriate alternative for metal, PVC, GRP and cast iron pipes.
The TRUFLO PVC pipes and fittings can be used for a variety of appliions like, irrigation, water supply, industrial process lines, swimming pools, firefighting mains, etc. This piping system is far better than CI, DI or RCC pipes, as it is light in weight, quick and easy to install, has excellent corrosion and chemical resistance properties, high flow rates, long life and economy.

receive water, as water will flow to that area from the other side. Water reaches all points with minimum head loss. At the time of fires, by manipulating the cut off valves, plenty of water supply may be diverted and concentrated for fire fighting.

The Sewerage and Water Board of New Orleans had previously selected HOBAS pipe for a nuer of projects for several other reasons including its superior flow capacity. The HOBAS potable water pipes deliver significant energy savings due to the low head loss delivered by the smooth pipe interior.
). Product specifiions PVC U pipes and fittings for water supply, drainage and sewerage under pressure should now be purchased to the relevant part of BS EN 1452.
In Table 4, the head loss drops rapidly as the ID increases. For example, transporting water through a pipe results in 16.2 feet of head loss, while a 6 inch pipe has a head loss of only 1.1 feet. This reduction in pipeline head loss allows for the selection of

point C that is lower than water level in the pipes by 4 m. The pipe is 100 mm diameter and 15 m long. The highest point on the pipe B is 1.5 m above water level in the pipes and 5 m long from the pipes. The friction factor (4 f) is , with sharp inlet and outlet b.
You can easily convert inch dimension to mm by multiplying it with 25.4 and rounding as follow; Outside diameter above 16 inches rounded to nearest 1 mm Outside diameter 16 inches and below rounded to nearest 0.1 mm Pipe wall thickness are rounded to
16 Re = ( ) In summary, the hydraulic gradient i may conveniently be expressed in terms of a dimensionless wall friction factor f. This factor has the theoretical value f = 16/Re for laminar flow along a smooth walled pipe. There is no corresponding theoretical
tricky. Copper 3/4 inch pipe, for instance, doesn’t measure 3/4 inch anywhere — its outside diameter (OD) is inch and inner diameter (ID) is inch for Type M pipe (a designation relating to wall thickness). But HDPE 3/4 inch pipe is inch OD and 0
Finally, select the size of the pipe using Figure 4. Note: Unit sizes provided in the table 1 and table 2 is in mm, but the size of pipes in the chart is in inch. 1 inch= , 1 ft. = , 1 gallon/m= /m. Water velocity should not be greater than 2
Various types of pipe fittings are available in pluing systems for different purposes and functions. A pipe fitting is used in pluing system to join multiple pipes of same size or different sizes, to regulate the flow or to measure the flow. They are made up of
The pipes used to transport potable drinking water in a home pluing system use different materials than those used for the pipes carrying drain water. Your home may have a pluing system that uses all one type of material for the water supply pipes, but don''t be surprised to find several types of pipes, especially in older homes that have seen many repairs or updates.
In Table 4, the head loss drops rapidly as the ID increases. For example, transporting water through a pipe results in 16.2 feet of head loss, while a 6 inch pipe has a head loss of only 1.1 feet. This reduction in pipeline head loss allows for the selection of a Puhui Pipe manufacturer in China
WSAA Water Supply Code of Australia specifies a minimum diameter of DN100 for all water supply systems which incorporates a fire service (excluding cul de sacs) and allows DN63 PE for mains in cul de sacs serviced by fire hydrants on adjacent mains.
Here''s a detailed list of the different types of pluing pipes and tubing used in residential house pluing systems. We include an explanation for what each type is used for along with a HDPE equal tee example of each. At the end check out a pipe size chart for sizing info.
