Embodiment 1

[0080] Take 5.5MPa, 190.5mm inner diameter, and 205mm outer diameter glass fiber pipe 30 with pressurized opening as an example, and the opening diameter is 150mm.

[0081] 1. The fiberglass pipe 30 is reinforced with pressure-opened pipe sections. Determine the 300 mm of the reinforced pipe section with pressure drilling, and grind the surface of the glass fiber pipe 30 to make the surface of the glass fiber pipe 30 rough, and the thickness of the grinding is not more than 0.2 mm. The connecting pipe section 20 with an inner diameter of 155mm is buckled at the pre-opening position of the glass fiber pipe 30 in the middle of the pipe section. Adopt the same type of glass fiber cloth (positioning belt) as the glass fiber pipe 30, and evenly smear the mixed solution of the glass fiber pipe 30 in the original production process of liquid epoxy resin and curing agent on the glass fiber cloth, press the glass fiber pipe 30 According to the requirements of the production process, t...

Abstract

The invention provides an auxiliary device for opening holes for glass fiber pipes, comprising: a sealing sleeve, which is arranged coaxially with the glass fiber pipe, and the sealing sleeve is detachably hugged on the outside of the glass fiber pipe, The pipe wall of the sealing sleeve has a through hole for avoiding the punching tool; the sealing member is arranged on the sealing sleeve, and the sealing member is located at both ends of the sealing sleeve; the connecting part, the connecting part and the The sealing sleeve is connected and communicated with the opening. Before drilling the glass fiber tube, the sealing sleeve is set on the outside of the glass fiber tube, and further sealed by the seal to ensure the sealing of the pre-punched glass fiber tube. Pass the punching tool through the opening to punch holes in the fiberglass tube, and the pressure oil overflowing from the glass fiber tube will be effectively sealed by the sealing sleeve, so as to avoid the pressure oil spraying out and causing safety hazards. The hole opening auxiliary device in the present invention can punch a glass fiber pipe that works normally.

Description

technical field [0001] The invention relates to the technical field of oil and gas exploitation, in particular to an auxiliary device for opening holes for glass fiber pipes. Background technique [0002] High-pressure fiberglass pipes (referred to as fiberglass pipes 30 ) are often used in oil field sites. [0003] Compared with steel pipes, high-pressure fiberglass pipes are widely used in oil field production sites because of their strong corrosion resistance, fast construction speed, and low construction cost. [0004] In the prior art, when the branch pipeline is installed on the original high-pressure fiberglass pipe, production and processing must be stopped to avoid potential safety hazards caused by high-pressure oil spraying. [0005] In the prior art, there are the following problems in stopping production and processing branch pipelines: [0006] 1. The construction steps are complicated and the construction efficiency is low; [0007] 2. It takes a long time ...
