Issues with stainless steel spiral tube halves?
Thread Content
Recently, our company is going to receive a batch of chemical processing equipment, whose outer surfaces are equipped with stainless steel spiral semi-tubes. I’d like to ask my friends: are these stainless steel spiral semi-tubes formed by rolling a whole tube into a spiral shape and then cutting it into semi-tubes, or are they first cut into semi-tubes before being rolled into spiral form? Is it possible to roll a semi-tube into a spiral shape after it has been cut in half? Everyone is welcome to offer their advice!
After slitting with a sheet rolling machine, it is pressed into shape using specialized equipment, achieving complete formation in one step
In what applications are the half-coil and full coil of spiral tubes used respectively? What are the advantages and disadvantages? Let’s discuss this in depth, haha. The entire tube doesn’t need to be welded to the cylinder, but the fixing clamps do need to be welded. Since the internal and external media mix together, the risk associated with the entire tube is somewhat reduced, right?
The cylinder section can be directly made into a semi-tube from sheet metal, while the head section is bent from pipe material into a full tube according to the size of the tubes, and then cut into semi-tubes during fabrication.
For outsourced processing, professional manufacturers will give you advice; generally, sheet metal is used
Both the half-pipes of the cylinder are bent directly from steel strips. The semi-pipe on the end cap vertebral body is generally bent from a pipe and cut on-site during installation. Very few manufacturers are able to produce semi-tubes with steel strips for manufacturing head and cone components, but the price is high; it’s not much cheaper than those made by cutting whole tubes.
The regular semi-tubes of the cylinder section are generally fabricated from strips. If the end portion is irregular, it is possible to use a whole tube and then cut it in half, which is somewhat wasteful. For this, you can find someone who is professional in this area; they are experts.
May I ask how to make the cylinder part into a half-tube?
There are manufacturers in this field; the key is to have drawing equipment. Container manufacturers generally don’t do it themselves
