LIFE CYCLE OF DI WATER PIPELINE

Every living/nonliving thing has a life cycle. Life cycle is a very important thing in construction work because all construction works start with a huge investment. So constructed structure must provide  service for a certain period of time. The service life of structure widely depends on it's construction method, quality of work, actions on it during service life, environmental effects, changes done during it's service life, regular maintenance (not major repair). To know about the life cycle of water pipeline first I want say something about the construction material of pipeline. As we discussing about the life cycle of DI (Ductile Iron) pipeline so here I will write about Ductile Iron.

Ductile iron also known as ductile cast iron as it is advanced form of cast iron. Ductile iron retains not only all cast iron qualities but also provides more strength,toughness and ductility. The chemical composition of ductile iron is carbon, silicon, manganese, magnesium, phosphorus, sulfur, copper, iron. Ductile iron is flexible and can be bent without breaking. So as a pipeline construction material ductile iron can provide good service life. But the life cycle of pipeline not only depend on the type of pipe is used but also on how it is constructed.

The another important thing to have a good service life of pipeline is to maintain quality of joint. In case of ductile iron pipeline there are several types of joint. So before starting the construction work it is necessary to arrange training for the workers. This is the first step to prevent leakage of pipeline.

Next, during the construction work it is necessary to keep clean inside the pipeline. Never left any sand bag, wastage of food, cigarette filter inside the pipe, because when water flow inside the pipe these things will create obstruction, odor. So daily cleaning is important during construction work.

Another important thing is regular maintenance of pipeline such as valve chamber cleaning, inlet and outlet point water. checking during the natural disaster and repair if any damaged done by it, maintain the flow pressure as per specification because too much pressure will effect the joint which will result in leakage, following the operation rules exactly as directed by the constructor.

By ensuring these things I think DI pipeline for water supply will provide a same design service life and functional service life. And also the life cycle will be prevented from bad influence.

Butterfly Valve Installation and Chamber Construction

Image
How to install a Butterfly Valve and construct Chamber? Here I share some pictures describing procedures of Butterfly Valve installation and Chamber construction for 1200 mm diameter DI pipe. 1. 100mm thick cc casting with C20 concrete. Then make a layout for re-bar binding. 2. Then start re-bar binding according to drawing. In this case 16mm dia Grade 60 re-bars are used. Must maintain the c/c distance and clear cover. During bending the re-bar development length must have to maintain as per drawing. 3. When re-bar binding finish then the workmanship must be checked by the consultant. 4. After checked by the consultant start form setting. Use required size of block to maintain clear cover. Provide necessary support to prevent form failure during casting. In this case 75mm block are used.                                   5. Before casting check the slump value of concrete. Take cube for compression strength test.

Air Valve Chamber Construction

How to construct a Air Valve Chamber? Air valve in water pipeline construction is generally placed in higher position to release air maintaining the water flow through pipe smooth. Here I will tell you about the construction method of air valve chamber in case Ductile Iron Pipe. For your better understanding I have shared pictures of construction work with details. 1. Installation of All Socket Tee: First we have install the all socket tee DI pipe and joint a cutting pipe with tee. From center of tee pipe keep at least 3m clear to both sides for the ease of form setting work. After installation check the elevation of pipe and to maintain it use heavy sheet pile or H-beam and wire to hold the tee pipe.   2. After that start form setting around the Tee for concrete casting. The casting dimension is 2.2m x 2.2m x 1.7m. Keep 300mm clear at the bottom of pipe. 3. Concrete casting with C25 concrete.

COLLAR JOINT

What is Collar Joint in DI Pipeline construction? Collar joint is a type of joint which is generally used in case of DI Pipeline construction. The components of collar joint are; 1. Collar, 2. T-head bolts, 3. Gland 4. Rubber Gasket. Generally when there are different contractors work on a large pipeline construction or during bridge, culvert crossing it is not possible to carry on the work at same time which results in different segment of a same pipeline. To joint those segments we need to use collar. For this joint, it is necessary to maintain same elevation and alignment on both sides of the joint otherwise joint can not be done. To do this we need to expose both side when there is about at least 30m gap. During collar joint there are some checks we must have to perform which are gasket check, joint gap checking which is should be less than 5mm.
