How to check the quality of HDPE pipes?

2019-07-28

Plumbing wouldn’t exist without pipes, would it? These void cylindrical object is responsible for the transportation of liquids, gases, slurries, powders and masses of small solids to the supporting structures in various types of systems. However, just by implementing any pipes in our homes, properties and systems will not be enough to ensure that we get the best water supply. It is because there are many different types of pipes to choose from. Although from a long list of options available, HDPE pipes in Nepal is the best option for everyone out there who is looking to get the best water supply.

PVC, metal pipes, cement pipes, water pipes, etc. several different types of pipes are used in Nepal for water supply. However, it is often found that these pipes often create several problems after used for certain amount of time. HDPE pipes in Nepal is the newest and the most advanced product in town that is designed and developed using the latest technology.

However, just using HDPE pipes also may not be enough to get the best water supply that you are looking for. Even though HDPE pipes are built using thermal technology, which isn’t used in other types of pipes, buyers should be able to choose the best HDPE pipes from the rest in order to install the best HDPE pipes and have the most effective water supply.

The performance and quality of any water supply pipes will depend on the material used, processing equipment and the technology used to construct it. A lot of companies manufacture HDPE pipes in Nepal. If you get the products blindly without any thought, you might end up with the products that was built using recycled materials. Using such techniques to manufacture HDPE pipes will reduce the cost for the manufacturer, but it comes with the cost of a hugely degraded performance of the pipes. BN Mahto Group offers the best quality HDPE pipes in Nepal which are created using the highest grade elements that perform better than others even in harsh environment conditions. Here, we have provided some ways you can identify the quality of HDPE pipes.

Appearance

We all know about the popular saying that first impression is often the last one. This implies in case of HDPE pipes too. The looks and appearance of HDPE pipes will tell us a lot about their quality and how better will it perform after being installed. Therefore, it is very important for all the buyers to have a general idea about how quality and good HDPE pipes appear in its looks. We should always remember that in good quality and sturdy pipes, the outer as well as the inner surface is smooth and even.

Buyers should check for the presence of any sort of defects in its surfaces like bubbles, dents or any other impurities. If we notice any sort of irregular and uneven pipe surface, dull looking and with clear pitting, then we should understand that we have a low quality product in front of us. By checking these simple things, if we can get the best pipes then why not do it and get the top HDPE pipe.

Milling Strips

Milling strips of the pipes can also be checked to determine the quality of HDPE pipes. The strips of quality pipes milled by welding machine is usually brighter in its looks. They also should be strong and shouldn’t break easily and can even outstand repeated folding. Good HDPE pipe’s milling strips are brighter and won’t break easily. On the contrast, low quality HDPE pipe’s milling strips adorn a darker look and easily break after repeated folding.

Not just regular pipes, but HDPE pipes in Nepal are also made using recycled materials which reduces the cost for the manufacturers. We can separate low quality strips from good ones as poor quality strips often have whitish or other colors.

Butt Welding Joint

Butt welding joints should have smooth and symmetrical turn ups around the pipe circle and the depth of the turn ups should also not be lower than the pipe surface itself. Tolerance at both sides of the excircle of welding seams should not exceed more than 10% of the overall pipe thickness. The bottom part of the turn ups should also be a little bit wider than other parts in order to provide more strength.

Impurities, small pores and damages or deformation should also be checked as presence of these things might hugely affect the overall performance of pipe. Good butt welding often comes with longer, smooth and clean turn ups. On the other hand, poor HDPE pipes will have lot of blow holes in the surface and shorter turn ups.

Break Elongation

Break elongation refers to the ratio between the lengths when the pipe was broke to its initial length. When break elongation is more, there is more flexibility in the pipe and this also helps in enhancing the overall performance of the pipe. Hence, we should maintain as much elongation as possible during breaking the HDPE pipes to get the best out of them. While checking the quality, we should also keep in mind the fact that top notch HDPE pipes can be stretched upto 3.5 times of its original length without breaking.

Oxidative Induction Time (OIT)

Oxidative Induction Time or OIT is the time for the pipes to undergo Automatic Catalytic Oxidation reaction under the presence of high temperature and oxygen levels. OIT is used to know and display the thermal degradation capacity of the HDPE pipes. This metrics and the insights it provides is crucial in all the different phases including processing, storage, welding as well as during working on it. We should opt for HDPE pipes that have a longer OIT, as longer the OIT, the better is the anti-aging capacity of those HDPE pipes.

Hence, one should not just go for any HDPE pipes just because they are better than other types of water supply pipes. A thorough checking and inspection should be made in the factors listed above before a purchase is made so that one obtains the best water supply with HDPE pipes.
