Title:
ONLINE CONTINUOUS PRODUCTION PREPARATION METHOD FOR CONCENTRIC CONTINUOUS OIL PIPE
Document Type and Number:
WIPO Patent Application WO/2019/174093
Kind Code:
A1
Abstract:
Provided in the present invention are an online continuous production preparation method for a concentric continuous oil pipe, the overall coil of a prepared continuous inner pipe being guided into an outer pipe before the outer pipe is coiled and formed. The inner pipe winds around a production roller and horizontally enters guide machine frames by means of a pipe inverter; a plurality of the guide machine frames are arranged at the upper part of an outer pipe winding machine; and the inner pipe enters guide curve rails by means of the guide machine frames, is curved in the guide curve rails, and horizontally extends into the outer pipe before being coiled and formed. By means of the present invention, the deficiencies in a conventional concentric continuous oil pipe production method may be avoided effectively, the degree of dependence on space and operation is low, additional auxiliary heavy equipment is not required, the implementation process is simple, the efficiency is high, the cost is low, and the method is safe and reliable.
