A non-seam liner glass steel pipe and assembling method

Abstract

The present invention discloses a kind of jointless steel pipe with glass inside liner and its production method. It includes the following several portions: jointless inside lining glass pipe, seamless steel pipe, positioning ring pipe head, pipe hoop, pipe tail, draw hook, pipe head rubber cap and air nozzle. Said invention adopts a í‹pressure adsorptioníŒ method to make the external surface of glass pipe be stuck to the internal surface of seamless steel pipe so as to obtain the invented product. Said invention also provides the concrete steps of the í‹pressure adsorptioníŒ method. Said invented product can be used for making oil field ground oil transmission pipline, so that it has extensive application range.

Description

technical field [0001] The invention relates to a seamless lined glass steel pipe and its assembly method Background technique [0002] In oil extraction, the wax removal in the oil well pipeline is a technical problem that must be solved, because the wax in the pipeline not only affects the production, but also increases the labor intensity of the workers in order to clean the wax in the pipeline, so that the wax removal The wax cycle is long and the operating cost is high. In recent years, some domestic oil fields are trying to change this situation. Some companies have adopted stainless steel pipes and aluminum alloy pipes, which are not only expensive, but also the inner wall of the pipe is rough, and wax still hangs on the inner wall of the pipe, making wax removal difficult. [0003] Recently, we found from the data that in Japan's oil exploitation, the oil pipe is a steel pipe lined with glass. One section, not only has many seams, but also hangs wax. The wax remova...

[0002] In oil extraction, the wax removal in the oil well pipeline is a technical problem that must be solved, because the wax in the pipeline not only affects the production, but also increases the labor intensity of the workers in order to clean the wax in the pipeline, so that the wax removal Long wax cycle and high operating costs

In recent years, some domestic oil fields are trying to change this situation. Some companies have adopted stainless steel pipes and aluminum alloy pipes, which are not only expensive, but also the inner wall of the pipe is rough, and wax is still hanging on the inner wall of the pipe, so it is still difficult to remove the wax

[0003] Recently, we found from the data that in Japan's oil exploitation, the oil pipe is a steel pipe lined with glass. One section, not only has many seams, but also hangs wax, the cycle of wax removal is long, and it is easy to be brittle, which will increase the production cost of the enterprise
