A brief discussion on what requirements the specifications and appearance quality of high-precision cold drawn tubes need to meet?
No matter what product is produced, there are relevant regulations to define it, including product size, specifications, quality, etc. Only qualified products can be launched into the market for use. Taking high-precision cold drawn tubes as an example, what requirements do the specifications and appearance quality of this product need to meet?
In terms of diameter, the diameter can be controlled between 6 and 200mm; and the wall thickness can also be maintained between 0.5 and 21mm. It can be seen that there are many choices for product specifications.
Regarding the surface quality of high-precision cold-drawn pipes, in addition to not having some obvious defects, such as cracks, folds, crazing, cracks, rolling folds, delamination, etc., the negative deviation of the pipe wall thickness and outer diameter must not exceed the specified range. Only after meeting all the above requirements can it be considered a qualified product.
