Relationship between the material of the vertical pipe of the loading crane arm and the type of chemical product
Thread Content
For loading liquid chemical products in our warehouse, a top-loading method is used; a dip pipe (scientifically known as a land-based fluid handling arm) is inserted into the holes at the top of the tank truck for loading and unloading, with the part that is inserted being called the vertical pipe. A portion of our hanging pipes is made of 304 stainless steel, and the goods being handled currently are of Class A B type. It has been suggested that stainless steel is a ferrous metal, and the tank trucks used for transporting goods are also often made of stainless steel; therefore, friction and impact between the vertical pipe and the opening of the tank truck during insertion and removal can very likely generate sparks, leading to fire and explosion accidents. The vertical pipes need to be replaced with aluminum ones. Do any of you sea friends have experience in this area? Are there any relevant standards that set requirements in this regard?
The new oil tank specifications do not specify the material for the dip pipe, but if there are concerns, it can be replaced with an aluminum alloy material
The main issue is the large number of vertical pipes that need to be replaced; without any specific reason, the company will object to the additional costs, and carrying out the replacements on-site can also affect areas such as production safety.
Currently, most of the pipes in the oil tank are made of stainless steel; there should be no major issues as long as they aren’t replaced for now
Aluminum is necessary. It’s not just a matter of safety; the operating weight can also be significantly reduced
There are those made of stainless steel and those made of aluminum; neither presents any major problems. The key is to prevent sparks from being generated due to impacts; price-friendly gaskets can be considered for cushioning purposes. Of course, the gasket must be one that does not react with the material
The hanging tube can’t reach the bottom, right? However, there are coils inside that could cause collisions, so there is a risk. We have been using stainless steel for many years. Some aluminum products are not very compatible. Prone to deformation upon impact, resulting in sticking during extension and retraction
