The method described above is a repair method for mechanical damage found during construction. As for leakage in the operating state (not yet broken), bolts are generally used between the upper and lower sleeves, and there is an annular sealing ring inside the sleeve. Between the spiral steel pipe body and the sleeve, the oil and gas will not leak out, and the longitudinal direction is also sealed.
