However, if not properly installed, the systems may perform poorly or, at the extreme worst, fail to work at all. Now, here we discuss five mistakes to be avoided during the installation of MDPE pipe fittings for a successful pipeline that will last long.
1. Selection of Wrong Size and Wrong Type of Fittings
MDPE pipe fittings are available in other sizes and forms and it becomes crucial to select the most appropriate type for a particular application. If the wrong size and type are chosen may lead to leaks, pressure drops, or even low flow rates.
To avoid this, always adhere to the manufacturer's literature in choosing the right fitting size and kind. Check and compare the diameter of the pipe which has been measured accurately and see if they fit the MDPE pipes and the fittings. Ensure that the correct connection kind is used depending on the application like socket fusion or electrofusion and that the joints have been accomplished by an experienced connecting technician.
2. Failure to Consider Enough Time for the Fusion Process
Fusion is an important stage of MDPE pipe, and failure to wait long enough for the process may lead to the formation of weaker joints which can leak. Heating and cooling times have to be standard for socket fusion and the electrofusion processes.
For socket fusion, the appropriate temperature of the pipe ends has to be reached before placing the fitting. There are many results in pressure on the system after allowing enough cooling time. Electrofusion on the other hand suggested that there is a need to monitor temperature when using electricity in heating. Precaution should be taken to stick to the heating time and never hasten the process of fusion in any way.
3. Neglecting Joint Preparation
Inadequate preparation of the joint surface results in complications like under or overgrowth of the joint, weakness of the joint and early joint failure. To eliminate this effectively, it is essential to clean and dry the MDPE pipes before joining them. Make certain that the pipe ends are cut in complete line with each other and free of sap and burs.
The end of pipes used for socket fusion should be slightly tapered to fit snugly into the fitting socket. In electrofusion, the correct position of the joint should be identified on both the fitting and the pipe before heating. Appropriate surface preparation methods will ensure excellent and tight seals as well as durable fasteners.
4. Lack of Focus on Support and Alignment
MDPE pipes must therefore be properly supported and placed to keep undue stress and strain on the interconnected joints to a minimum and in turn, fail. It is advisable not to install MDPE pipes on useless lengths greater than those advised by the manufacturer since the pipe tends to sag and consequently may be damaged.
Also, during MDPE pipe fittings installation, it is recommended that the MDPE pipes are well aligned so that there will not be stress concentrating on the joints and fittings. If pipes are buried, then refer to the manufacturer’s guidelines in terms of pipe type and depth of cover necessary to envelop the pipe from potential harm resulting from ground movement, excavation or other influences.
5. Failing to Consider Adequate Documentation/record-keeping Requirements
To sustain and debug MDPE Pipe Fittings Installation there must be documentation and record-keeping done correctly. A lack of records makes it hard to establish a problem when it occurs and correct it to avoid water leaks, loss of service, or system failure.
To prevent this always include in your records pointing to the installation including the size of pipe and fitting, fusion technique, alignment and support systems and any other important factor. Document any changes that were made in the system over time together with other paperwork to simplify the access of records in future.
Conclusion
All in all, it is necessary to understand and follow the mechanisms of MDPE pipe fittings installation to provide durable pipeline typology. Therefore by avoiding the following five mistakes, your system will be efficient and dependable and will stay strong for many years to come.
To ensure that the fusion process works effectively, remember to select the appropriate size and type of fittings, make sufficient time for fusion, clean and prepare joints correctly, ensure corresponding support and alignment and document and record appropriately. If these aspects are paid much attention, one is fully qualified to harness the numerous advantages of MDPE pipe fittings in the application.
