Pipes of PE pipe this one, it can be said to be widely used, and products and keywords or web site, so, based on these two points, is must pay attention to the product, and carefully for their work and study, in order to well grasp and apply, in turn, to benefit themselves, rather than nothing.

1. What is generally used to connect PE pipe and PPR pipe? If it is a small caliber pipe, and how to proceed?

PE pipe and PPR pipe, in its connection, generally speaking, is the flange connection, rather than other connection. As for the small-caliber pipe, it can be connected with tooth accessories. This way, you can connect the quality, and at the same time, have a good connection effect.

2. Do the three kinds of PVC pipe, PE pipe and PPR pipe have the same field in use?

PVC pipe, which is mainly used in drainage pipes, PE pipe, which is mainly used in the middle and low pressure natural gas pipeline and water pipeline, and PPR pipe, which is used in the building cold and hot water pipeline. Therefore, these three kinds of pipes, in the field of application, there is no cross. So, in this case, the answer is certainly no.

3. How to sample PE pipe? In addition, what is the permissible flow rate of combustible gas in the pipe?

PE pipe sampling, generally speaking, is for each batch once, if less than 5000m, then extract once, on the contrary, is a batch of sampling. If the formula or process is changed, it is necessary to re-test it. And the flow rate of combustible gas in PE pipe is stipulated not to exceed the upper limit of the pipeline pressure grade, so it is limited.

These problems, are about PE pipe this kind of pipe, and at the same time, we must know and clear, because only in this way, can let oneself learn something, rather than nothing. It's also a great learning opportunity, so make the most of it instead of wasting it.
