What is the quality of large steel-lined PE storage tanks?
Thread Content
We are currently preparing to install several horizontal storage tanks with a capacity of 70 to 100m3. Carbon steel cannot be used, and stainless steel is too expensive. We want to use carbon steel lined with PE or fiberglass. From my heart, carbon steel lined with PE is more suitable and looks more formal. Is the choice of resin for fiberglass reinforced plastic reasonable and what is the construction quality? Resin is a complex mixture of components. Will there be trace reactions or collisions with the storage materials? The aging of fiberglass will affect the service life, etc. But what about steel-lined PE? What I worry about is the processing quality. What should I do if the glue comes off? Corrosion may occur, and if iron ions cannot be mixed into our materials, there will always be some worries in my mind. What is the current quality of steel-lined PE for large domestic storage tanks, and how is its application in actual production? What is the quality of steel-lined PE products from Wuxi Xinlong Company? Wait, welcome to participate in the discussion, thank you!
There is a store in Shanghai with pretty good linings. It seems to be called Shanghai Teflon, a Japanese-owned company.
There are several companies with foreign investment in rubber lining equipment, including those from Japan, Germany, and Taiwan. This technology has been around for many years now, and they will choose what kind of glue board to use based on the conditions of your container. Be sure to find a regular manufacturer to do it. Otherwise, the situation you mentioned will occur. If it is a small subcontracted factory, it is best not to do so. Now after layers of profits are peeled off, it’s hard for subcontractors to make good stuff.
Whether it is lined with polyethylene or fiberglass, be sure to find a regular manufacturer. The quality of the lining made by regular domestic manufacturers is guaranteed. You can rest assured about this. You can ask them to provide formal quality control documents and construction documents.
Not necessarily. One year we had a sulfuric acid storage tank that was required to be lined with PTFE. It turned out that it was lined in Jingxian County, Hebei Province. When it was transported to the construction site, the acceptance personnel stepped in and stepped on it. Their workmanship was not good. They used a few buckles to fix it on the steel plate, not hot melt. As a result, they were all scrapped and suffered heavy losses.
It is recommended to the poster to use rotational molding. There are several in Wuxi. Our company has used storage tanks from Wuxi Xinkaihe, and the quality is acceptable. It seems that the largest rotomolded tank is 50 cubic meters. If it is larger, you need to consult. Rotational molding is hot-melted and has a tortoise shell protective net, which is probably a bit more reliable than the "lined" one.
The person on the 6th floor said it very well. We also use that kind of container, but our container is only 30 cubic meters! I wonder if a container as big as yours will work, :)
When using PE anti-corrosion, the material temperature is required to be below 70 degrees. If the temperature exceeds 70 degrees, it will have a great impact on the lining. In addition, the price of PE anti-corrosion is much lower than that of FRP anti-corrosion. The construction quality is mainly affected by the treatment of the base layer. The rust removal inspection results of the base layer must be tracked, and then the thickness of the lining plastic and the quality of the lining plastic fit are required to be inspected. The choice of the construction unit is determined by comparing its specific construction engineering conditions and several survey results, which is very critical.
Haha, it’s interesting. You need to find a big brand to line PTFE. Although the anti-corrosion thing is strong, it is not easy to line it. Pan Zhaojin is the number one person in China for PTFE anti-corrosion. It is headquartered at Jinti, Nantong, Jiangsu, and distributed in the west of Sichuan Jinti Yongtong PTFE Anti-corrosion Technology Co., Ltd. http://www.yonton.com/product.asp?id=53
