Composite plate coiled tube
Thread Content
From a technical standpoint, composite plate coils are required to have only one longitudinal seam. As for small-diameter plate coils such as those with dimensions of φ168×(10+3), φ219×(8+3), φ273×(9+3), and φ325×(10+3), what methods do you use for their processing and fabrication in order to meet these requirements?
For those with a small diameter, stainless steel is used directly; for those with a larger diameter, lining tubes or surfacing welding structures can be employed. It is difficult to handle composite panels in small batches.
The connections for composite panels generally adopt a liner tube structure; otherwise, it is very difficult to wind the tubes
A stainless steel tube can be used directly.
I went to request a change to stainless steel pipes, but the design team disagreed. I don’t know why.
