Our factory uses inner-layer PTFE metal braided hoses; I’ve heard that flexible hoses are also being used nowadays. It’s available for sale there. Where is it produced, and who uses it? ， ， -
Using a filling hose, also known as a universal filling fitting, is required by safety standards. A quick search online will reveal several manufacturers. The one in Lianyungang is better.
Previously, filling was done using hoses, but now the standards prohibit the use of hoses; instead, transfer pipes are required, as can be found online
Now, dip tubes are being used for filling liquid chlorine tank trucks. In the past, flanges suitable for the tank trucks of customers who came for regular fillings were used; but now, dip tubes make the process more convenient. I know a dip tube company that I can recommend to you – Lianyungang Lianhan Petrochemical Equipment Co., Ltd. You can search for them online to get in touch.
The quality of flexible hoses also varies, so it is essential to conduct a thorough inspection.
We have been using flexible hoses for a long time; they seem to be from Lianyungang, and they perform well. Suggestion: Carbon steel is sufficient as the material ； Prepare more seals in advance ； From a process perspective, consider improvement measures to prevent wet air from being drawn into the flexible hose.
We have used the flexible hoses from Lianyungang Sanhe, Shuaibao, and Dewei – they are quite good. As long as proper maintenance is carried out and the hoses are used regularly, a set of seals can last for 3 months without any problems. A set of flexible hoses can generally last around 2 years
It is advisable to install a ball valve in front of the quick-flange connectors of the liquid chlorine loading and unloading nozzles!
Liquid chlorine is connected using a duckbill valve. Flexible hoses are widely used in logistics hubs such as ports and railways. In China, the areas with a large number of manufacturing companies are located near Lianyungang; when making a choice, it is sufficient to check whether the manufacturing company has obtained certification from CNPC or Sinopec. Ask them to provide swivel joint spare parts (seals) at the time of purchase.
Can you provide information on which manufacturers use flexible hoses to transfer liquid chlorine? How effective is it?
Lianyungang has many manufacturers of flexible hoses; for example, *** Petrochemical Equipment Co., Ltd. is one such manufacturer
