Problems solved by technology

[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

Embodiment Construction

[0011] From Figure 1 to Figure 4 It can be known from the accompanying drawings of the present invention shown in the embodiment, first referring to figure 1 The structure of the lined glass steel pipe includes a seamless glass liner 5, a seamless steel pipe 4, a positioning ring 8 for fixing the size and position of the lined glass pipe 5 and the seamless steel pipe 4, the pipe head 2, Pipe clamp 3, a pipe tail 6 pull hook 7 that can ensure continuous operation in the heating furnace, and an air nozzle 1 on the rubber cap of the pipe head 2, which is used to cool the steel pipe with water and blow in compressed air after it comes out of the furnace When the front end of the glass tube 5 is cut open, and the air pressure is 0.3-0.5 kg / cm2, compressed air is blown in through the air nozzle 1, so that the outer wall of the softened glass tube 5 is firmly pressed and attached under internal pressure. On the inner wall of the steel pipe 4, it is mainly due to the peroxide layer ...

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...
