Due to personal work reasons, I would like to investigate the types of materials used for the pipelines carrying the electrolyte solution (30%, 80-90 degrees) in the cathodes of various enterprises. With the permission of Dafeng Chaoban, I am posting this reward notice; the deadline for submitting responses is set at one week, ending on 2009.11.1. The details requested for the reward are as follows: 1. A detailed description of how the material used by your company in this application is utilized, including things such as the service life of the PPH material, any problems that have occurred over time, whether another material has been used instead, as well as the names of the manufacturers of that material and those of your company’s own (if it’s not convenient to disclose these names, they can be sent via text message). 2. The characteristic curves of PPH, such as temperature-strength relationships and temperature-corrosion rate curves, etc. Scoring criteria: The first item provides background information, but there is no response from the manufacturer (or I did not receive a text message); only a general score will be given. For the reply, award 3–5 points of charm; if the second relevant curve is correct, grant 3 points of charm. If both criteria are met, award 5 points of charm. Please ask the other three moderators not to rate this post; to avoid too many pinned posts, please help to promote it promptly. Thank you. Any discussion-based reply that does not meet the above two criteria will be deleted directly; thank you for your cooperation.
I’ll be the first; I remember sending you a text message last time. Add charm. Haha
1# Benben Xuan: When our company was expanding, a female salesperson came to promote the use of PPH pipes as a substitute for 310S pipes. However, out of a sense of caution, our company did not adopt this product. Later, we found out that there is a chlor-alkali factory in Hebei that uses PPH pipes; I’m sorry, but after checking I’m not sure which factory it is, though it’s definitely in Hebei. Personally, I think the PPH outlet has a certain level of competitiveness. The only drawback of this outlet is that, just like PVC, it requires many supports; otherwise it sags and looks unsightly.
Our factory has used PPH pipes in the catholyte pipeline system, but the results were not satisfactory. In my opinion, there is nothing wrong with the PPH pipes themselves; however, two issues must be addressed properly during use: 1) construction issues – the welding of the pipes must be carried out strictly in accordance with the requirements； Expansion issue of the 2-pipe route. The manufacturer’s data is available for other performance curves; there’s no need to collect them
