Abstract
The utility model provides a pipeline used for transporting petroleum and natural gas, which comprises a pipe body, wherein two ends of the pipe body are connected with stainless steel transition sections, and the stainless steel transition sections are 300mm-320mm in length. According to the pipeline used for transporting petroleum and natural gas, the two ends of the pipeline are connected with the stainless steel transition sections, the pipelines are in abutting joint in installation, waste heat of welding will not affect anti-corrosion properties inside the pipelines, anti-corrosion properties of welding areas are remained unchanged, mediums are guaranteed to be transported normally after the pipeline takes service, and maintenance frequency of the pipeline is greatly reduced.
Description
Technical field
The utility model relates to a kind of pipeline, particularly a kind of pipeline that is used for the transfer oil rock gas.
Background technique
The existing pipeline that is used for the transfer oil natural gas comprises body, at the internal surface of body spraying organic coating, forms the anticorrosive paint layer, is used for anticorrosion to body.Tube and tube butt joint during installation; In the welding region vicinity; Because receive the influence of welding thermal cycle, the anticorrosive paint layer of this place's internal surface suffers destruction to a certain degree, has reduced preset coating antiseptic performance; This zone is the corrosion-resistant weakness in the fed sheet of a media process, and about 80% body leaks and occurs in here.
Summary of the invention
Near the pipeline that is used for the transfer oil rock gas that the purpose of the utility model provides surface, a kind of pipe end endoporus place is welding heat affected when not docked, antiseptic property is good, the tube and tube joint is difficult for taking place leakage phenomenon the welding region overcomes the deficiency of existing technology.
The pipeline that is used for the transfer oil rock gas of the utility model comprises body, is connected to the stainless steel changeover portion at the two ends of body, and the length of described stainless steel changeover portion is 300 millimeters～320 millimeters.
The utility model is used for the pipeline of transfer oil rock gas; Owing to be connected to the stainless steel changeover portion at the body two ends; Tube and tube butt joint during installation, the welding waste heat does not influence the antiseptic property of organic coating in it, and the antiseptic power of welding region is remained unchanged; Guaranteed after the piping erection the normal conveying of medium is greatly reduced the maintenance frequency of pipeline.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
As shown in Figure 1: 1 is the body of transfer oil natural gas, is connected to stainless steel changeover portion 2 at the two ends of body 1, on the inwall of body 1, is coated with organic coating, forms the anticorrosive paint layer, is used for anticorrosion to body 1.The stainless steel changeover portion 2 at two ends is along the axial length A of body 1, and the heat that when butt welding, produces does not exert an influence to the organic coating beyond the stainless steel changeover portion 2 and is advisable, and can between 300 millimeters～320 millimeters, select.Be welding between stainless steel changeover portion 2 and the body 1, connect through weld seam 3.In order to keep the intact of anticorrosive paint layer, must carry out the soldering of stainless steel changeover portion 2 earlier.
Tube and tube butt joint during installation, the welding waste heat does not influence the antiseptic property of contiguous organic coating in it, makes the antiseptic power of welding region unaffected, has guaranteed after the piping erection the normal conveying of medium has been reduced the maintenance frequency of pipeline significantly.
