With the continuous development and progress of my country’s science and technology, my country’s demand for oil and gas resources has become greater and greater. In order to promote the development of my country’s economic construction and meet people’s normal lives, ground construction is an important link in the process of oilfield development and exploration to ensure production The key means of safety, especially the installation of pipeline construction equipment and the construction technology of gathering pipelines, play an important role.

On the characteristics of the corporate piping system.
Among all the equipment in power plant operation, pipelines are one of the most indispensable equipment, which are concentrated in EH oil pipelines, lubricating oil pipelines, jack shaft oil pipelines and boiler fuel oil pipelines. Such pipelines are generally ordinary 20 steel. Or 18-8 type stainless steel material, the related pipeline construction equipment has rich specifications and small pipe diameter.
The number of welds on the upper level of pipeline construction equipment is relatively large, and at the same time they are densely distributed; some pipeline welds are not easy to find and are relatively hidden, which often causes some problems during welding operations; especially stainless steel, which is high in chromium. Alloys and material types are unusual. Usually, when pipeline construction equipment is used, relatively large intergranular corrosion and hot cracking will occur, and the difficulty coefficient when completing welding work is relatively large.
About the characteristics of pipeline construction equipment welding.
Welding of pipeline construction equipment requires argon arc welding. For oil pipelines with a diameter of less than 60 mm or a thickness of 5 mm, the welding process for pipeline construction equipment can be full argon arc welding; if the diameter of the pipeline is greater than 60 mm If the thickness is greater than 5 mm, the relevant technicians need to change the welding process to argon arc welding bottom arc welding cover.
The key reason for this is that in stainless steel, the content of cr is already above 13%. A little carelessness will cause oxidation or excessive burning of the welding root. Therefore, when welding pipeline construction equipment, it is necessary to Argon filling or mixing of inert gas is carried out inside, so as to achieve the protective effect and ensure the welding construction quality of pipeline construction equipment.
Analyze the causes and characteristics of common problems during welding of pipeline construction equipment.
In recent years, some power plants have been shut down due to pipeline weld leaks or due to the quality of system welds. The existence of such phenomena will not only have a very bad impact on the overall operation, but also make the safety of the plant fall into threat situation.
In the construction of pipeline construction equipment welding engineering, there are two defects in welding, namely surface and internal defects. Surface problems can be discovered by the naked eye, but internal defects cannot be discovered in time by only relying on the senses. At this time, technicians and detection instruments are required to inspect pipeline construction equipment. Only through accurate inspection of the instrument can the problem be clearly known. Where is the root cause.
The welding quality of pipeline construction equipmentwill have a great impact on the operation of the unit. In other words, if the operation of the unit does not stop, it is probably because the pipeline construction equipment has welding quality problems.
Why do these problems occur in pipeline construction equipment? The reasons can be found from the following aspects:
l Because the pipeline construction equipment design unit only gave the system diagram but not the layout diagram, the construction personnel carried out the construction based on the site conditions and construction experience. The welding technicians did not know the location and quantity of the welding joints, so they could only make visual inspections or estimates based on their own experience. There will be a shortage in the number of weld inspections, which increases the probability of missing weld inspections;
l In the welding process of pipeline construction equipment, relevant technical personnel did not pay much attention to the particularity of the pipeline medium of the oil system, resulting in a low proportion of non-destructive inspections and potential safety hazards;
l When inspecting the welds of pipeline construction equipment, the relevant technicians usually only pay attention to the welds of the main parts and start the inspection, ignoring the inspection of other common welds, which may easily cause omissions;
l There are irregularities in the direction and layout of construction pipelines and brackets of pipeline construction equipment, and even stress and other reasons. As a result, the weld is not only the weakest part of the pipeline, but also the source of the first problem;
l Because the construction period of pipeline construction equipment is tight or there are requirements on the schedule, some who do not have welder skills or do not hold welder certificates will also temporarily serve as welding technicians. Such personnel who have not received professional welding training usually operate They are all conventional and ordinary welding skills. In the welding operation of pipeline construction equipment, there are problems such as insufficient sense of responsibility and low attention. At the same time, the quality of the plumber’s counterpart is not up to the standard and the awareness is relatively weak. Such problems will lead to pipeline construction equipment. There are quality problems and safety hazards in the weld joints.

With the progress of society and the development of economy, people's demand for resources is increasing.From cars that need diesel to power plants that need oil.In short, oil, natural gas and other resources have become indispensable in daily life.But conventional rail and cruise transport is slow and uncertain.Gradually, people invented the method of pipeline transportation.
The transportation volume of pipeline transportation is large. Most of the pipeline is buried in the ground, which covers less land and is less constrained by terrain and objects, thus shortening the transportation distance.Sealed transportation, safe and reliable, long-term continuous and stable operation;Easy to manage, easy to realize remote centralized monitoring.
As a result, a large number of pipeline laying work was carried out in various countries, and thus the related companies specializing in pipeline laying work were also derived.We are specialized in providing pipeline construction equipment company.
Pipeline construction process
Surveying and setting out→and cleaning the construction work belt；To construct the construction road→to transport the anticorrosive pipe→to process the groove→to redistribute the pipe→to prepare the pipe mouth；Pipeline fitting-up→pipe fitting-up and welding→welding joint inspection→heat shrinkable sleeve (tape) bushing→trench excavation→pipeline trench→pipe fitting-up;Pipeline welding→welding joint inspection →cleaning and pressure test→pipe trench backfilling→geomorphologic restoration.
The following short description gives the working procedure in outline. It can in certain details be modified when required.
Step 1. The tank bottom – plates are placed on the prepared foundation and welded together.
Step 2. The beams or lattice work of the roof are assembled and finally joined to the upper rim of the shell ring.
Step 3. The jacking equipment is installed in the tank. The plates of the second shell ring (next to the top ring) are positioned outside the first one.
Step 4. The completed part of the tank (roof and top shell ring) is lifted hydraulically to a height at which the plates of the second ring can be moved into place and the roof sheeting can be completed.
Step 5. The plates of the second shell ring are located exactly and welded together to the lower edge of the first ring.
Step 6. The plates of the third shell ring are placed outside the second shell ring.
Step 7. The completed part of the tank (roof the two uppermost shell rings) is lifted.
Step 8. The above cycle of operations is repeated until the last (bottom) shell ring is finished.
Step 9. The entire tank is lowered down to the bottom plate and welded to this.
Step 10. The lifting equipment is dismantled.
The tank construction process needs two kinds of equipment, respectively is the welding machine and the hydraulic jacking system, the welding machine is divided into the horizontal welding machine and the vertical welding machine;the hydraulic jacking system is also divided into senior hydraulic jacking system and simple hydraulic jacking system.(If your tank is bottom to top,you don’t need the hydraulic jacking system.)
