? 2. This process determines its limited performance. Generally, seamless steel pipes have low precision: uneven wall thickness, low brightness on the inner and outer surfaces of the pipe, high length cost, and pits and black spots on the inner and outer surfaces are not easy to remove; Water can be used for cleaning.

3. Detection and shaping must be done offline. Therefore, it shows its advantages in high pressure, high strength and mechanical structure materials. Stainless steel coils shall not be scrubbed with alcohol!

4. The material of the coil tube undergoes elastic and plastic strain under the action of hydrodynamic force. If the stress is large enough, the stainless steel coil will break. Clean the attention channel and interface of stainless steel coil.

?

5. Do not let the coil contact with acidic medium; Stainless steel will corrode when it meets acidic medium.
