Selecting HDPE pipe in Nepal has become a prominent choice for most of the people who need piping service for various purposes. Due to the vast benefits HDPE pipe provides while comparison with other types of pipes, there has been a huge surge in use of HDPE pipe in Nepal. This versatile and sturdy pipe can be used for various piping purposes like providing drinking water supply, in drainage systems, etc. and it has also become more popular due to its multi-purpose functionality.
With such rapid rise in use of HDPE pipe in Nepal, its area of application has also grown rapidly. People want to use HDPE pipes in as many ways as they can. As HDPE pipes are used in such an expanded manner now, often fitting components are used along with the HDPE pipes to make sure that the pipe perform in leak-proof and long lasting manner. Pipe fittings can also be of several types depending on the material used to build and also along with the type of joint that is to be used. Here, let us check out some of the most common materials that is used to manufacture fitting materials so that you will also be able to select the perfect pipe fitting when necessary.
Cast And Malleable Iron
These generally fall under hubless and bell-and-spigot styles. Hubless designs generally rely on couplers that secure the outer diameter of the pipe. Also known as rubber pipe couplings or rubber plumbing couplings, they are most suitable for use while transferring form one material to another one. Bell-and-spigot fittings are joined primarily with gaskets that fit inside the bell and accommodate the fitting.
This type of fitting material is very popular one for use in HDPE pipes in Nepal. Also, with both malleable and ductile fitting methods available, along with improved mechanical properties and reduced cost has only resulted in more excessive use of this fitting material.
Steel And Steel Alloys
Steel pipe fittings are generally laid over a mandrel from welded or seamless pipe. When working on pipes of small sizes, they are often threaded to match the pipe ends. As size and pressure of the pipe increases, they are welded in place using butt-weld or socket-weld methods. The welding methods are often used and suits high end works. Flanges are also used and are connected via bolts. Using flanges makes breaking the pipeline feasible and it becomes easier to do additional work like inserting valves.
Steel pipe fittings are often used in sanitary applications such as dairy and food processing organizations. They can easily be connected with quick connect clamps which enables dismantling of the pipes for cleaning purposes. Steel and metal pipe fittings are popularly used while using HDPE pipe in Nepal as they can be used in forms such as metal pipe end caps or 180 degree pipe elbows.
Nonferrous
Aluminum fittings are generally cast. These fittings are available in the same form, shapes and sizes as the steel fittings themselves. In addition, aluminum threaded fittings such as caps or nipples are also available and these also feature a combination of butt weld and socket weld connection styles. MIG & TIG processes are used to when implying aluminum fittings in the piping systems.
Aluminum pipes is also a popular option for creating hardnails, along with using in a fittings for structural applications that are of both weldable and slip-on / clamp-on varieties. Brass fittings are also available as per need of the diameter of the pipe, and are often assembled using soldering when used in HDPE pipes in Nepal.
Concrete
Concrete pipe fittings are available in a wide variety of styles as per the necessity of the piping project. Concrete pipe fittings are used with HDPE pipe in Nepal in areas like large civil projects and water control projects. While using concrete fittings, apart from using typical wye connections, specialized fittings also need to be used according to the utility hole portals and various types of vaults used. Usually with this type of connection, shouldered ends on fittings are used which are joined with the counterparts of the receiving pipe. In addition, a rubber gasket can also be used which gives a leak-proof and stronger joint.
Plastic
Plastic pipe fittings are available in both socket weld as well as threaded fitting types and is very popular choice for fittings for HDPE pipe in Nepal. Socket weld fittings are the most common choice and is usually designed to be placed chemically and its installation is quick and straightforward.
The plastic pipe fittings come in several forms such as elbows, caps, tees, reducers, wyes, couplings, unions, crossings, etc. to name a few. These fittings can also be used in case of structural use such as in case of fences, railings or furniture grade use. Apart from using plastic fittings themselves, they can also be combined and used with other type of fittings such as CPCV and ABS.
Plastic fittings are also very popular as they provide facility of easy disassembly. Hence plastic fittings are usually the top choice for using with HDPE pipes in Nepal in applications like plumbing or sink drains, which makes clearing clogs and blocks easier.
Glass
We don’t see the use of glass fittings very commonly as it is used in specialized industrial process settings. Usually, borosilicate glass is the glass material preferred over others as it provides several advantages over other materials. Borosilicate has high purity and it will not contaminate the fluids in the work process. A good level of transparency it offers also allows inspection of the process as the work carries on and the smooth surface of borosilicate also prevents the residues from gathering in the inner surface of the pipe.
Vitrified Clay
Vitrified clay fittings are also used with HDPE pipes in Nepal for typical configurations such as used for sewer pipe installations. Generally, bell-and-spigot is the preferred coupling method used in this type of fitting. An O-ring or gasket is used to seal this type of fitting joints.
Since HDPE pipe use in Nepal is so common that using HDPE pipes has almost become a sort of trend. We may also be using HDPE pipes next time any piping work needs to be done in pour homes or offices. Hence, having idea about HDPE pipe fittings will only be a good thing for everyone as fittings will most definitely used when installing HDPE pipes and you will be able to choose the right fitting according to the situation.
