摘要

Method for settling on coil coated tube mechanically coated tube mechanically, and method for manufacturing a coated tube mechanically. Methods to settle on a tube coated coil mechanically (MLP) are described.This includes the steps of: winding the MLP (12) on a coil (10) in the complete or substantial absence of internal pressure above the ambient pressure in the MLP; uncoiling the coil MLP; align and fix the length of the MLP in complete or substantial absence of internal pressure above the pre Pressure environment.To provide a MLP to settle down; and / or the steps of: winding the MLP (12) on a coil (10) resulting in the formation of wrinkles in the MLP uncoiling the coil winding; MLP; aligning and straightening the MLP not wrapped to provide a basis for MLP having wrinkles 4 mm height, removing wrinkles. If any The EBU, while reralizando the hidroteste which is used to check the tightness of the fluid line.By minimizing the size of the wrinkles and / or particularly selecting the coating of MLP, the methods of this invention allow for winding and unwinding the rapid, safe to be implemented to provide settlement more economical, fast and secure a MLP.
