In actual operation, in order to ensure that the installation quality of pipeline construction equipment meets the construction requirements, targeted solutions must be taken according to the problem and its cause. The following will explain the installation of pipeline construction equipment before, during and after installation.
Here is the content list:
l Regarding the control of pipeline construction equipment before construction.
l Regarding the control of pipeline construction equipment during construction.
l Regarding the control of pipeline construction equipment after construction.
Regarding the control of pipeline construction equipment before construction.
Before construction, in order to ensure that the material of the pipeline construction equipment used meets the industrial requirements, strict inspections need to be repeated, including repeated verification and review of the construction drawings, and careful inspection of the pipeline processing drawings to ensure that the pipelines in the drawings The processing regulations and calculated data meet actual requirements.
In addition, it is necessary to check whether the pipeline construction equipment required for installation has a quality certificate and whether the specifications and models of the pipeline correspond to the certificate, and whether it meets the corresponding installation requirements of the pipeline construction equipment.
Before construction, check the pipeline construction equipment for damage and other quality defects that affect the construction. In order to get a more accurate understanding of the pipe material, professional quality inspection instruments can be used. For example, high-pressure pipelines can be detected by the monitoring method of magnetic flaw detection. Ensure that the material of pipeline construction equipment meets industrial production requirements.
In terms of capital investment in the installation of pipeline construction equipment, manpower, materials, and instruments and tools used are the main capital consumption objects. Manufacturers need to have a detailed grasp of the use of funds to reduce costs as much as possible without affecting the quality of the project. When selecting manpower, low-skilled workers should be employed for jobs with low technical requirements. When selecting materials, pipeline construction equipment is often selected for comparison. Before construction, it is also necessary to conduct professional skills training for construction personnel to enhance their work skills.
Regarding the control of pipeline construction equipment during construction.
During the installation process, when the pipe is cut according to the drawings, it is necessary to use the corresponding operating tools and methods to cut according to the construction requirements and the pipe material to avoid damage to the pipe. When connecting pipes, the main construction methods are hot bending and cold bending.
Hot bending is performed in the pipeline construction equipment installation process after heating treatment, specialized functional personnel make it deform according to the construction requirements; cold bending is carried out at room temperature, the pipeline construction equipment deforms according to the construction requirements. Since heating will cause mechanical deformation of the pipeline, cold bending processing methods are mostly used in the construction process. In hot bending, different heating fuels, heating pipeline construction equipment, and heating techniques must be used according to different pipeline materials and construction requirements, and the heating temperature must be strictly controlled.
The hot-bent pipes must be maintained after installation to ensure their quality and durability. When welding, due to the different materials of the pipeline and the different connection methods of the pipeline during the laying process, the welding tools and techniques selected will be different. The welding technology requires high requirements, and the construction personnel need to have good experience and technology to make the pipeline can be Therefore, experienced technicians should be selected for the welding process during the installation of pipeline construction equipment, and professional equipment should be used for testing after the welding is completed to see if seamless welding has been achieved to meet the engineering requirements.
Regarding the control of pipeline construction equipment after construction.
After the completion of the pipeline construction equipment, quality inspection and maintenance of the pipeline are required. When performing quality inspections, professional monitoring equipment is generally used, such as radiographic inspection, which can achieve non-destructive inspection. When the test is in progress, a unified test standard shall be adopted in compliance with the relevant technical standards, with special attention to whether the units used are unified.
After the pipeline construction equipment is installed, in order to better ensure the quality of the pipeline, it needs to be treated with anti-corrosion treatment. Generally, paint is applied to isolate the pipeline and the air in the water and oxygen from chemical reaction and rust. Extend the service life of the pipeline, and also improve the safety of operations for those who perform production operations.
Pipeline construction equipment is widely used in industrial production and has strict quality requirements. Due to the different pipeline construction equipment used in different industrial production environments, it is easy to have some problems during the installation process, which will affect the quality of the installation project. To ensure pipeline construction the installation quality of equipment meets the requirements of industrial production, and the installation process needs to be carried out in strict accordance with the construction requirements.
When using the tank welding machine, the operator puts the lamp tube into the fixture, presses the start button, the two pressing cylinders descend to position the workpiece in the ultrasonic mold cavity, and then the ultrasonic welding head acts to trigger the ultrasonic wave, and the welding head carries out the workpiece. After welding and welding, the cylinder drives the upper die to reset, the pressing cylinder rises, and the operator takes out the workpiece to complete one operation.

Automatic vertical welder is high-efficiency automatic welding equipment that uses current feedback closed-loop control of vehicle lift. The thickness of the welded joint can be up to 50mm at one time. Mainly used for thick plate welding in petroleum, chemical, blast furnace, shipbuilding and other industries. EGW vertical gas electric welding machine is a kind of high-efficiency automatic welding equipment improved according to the current feedback closed-loop control welding trolley. The main feature of automatic vertical welder is that the thickness is from 10mm to 50mm in one pass of forced water cooling. At the same time, the molten pool level is automatically controlled, and the wire extension length is automatically adjusted. Small size and light weight welding trolley, flexible and modular, easy to update and easy to use. Widely used in petroleum, chemical, blast furnace thick plate welding and shipbuilding industries.
In most cases, the EGW used in the tank welding machine uses carbon dioxide gas as a protective gas, but sometimes pure argon, argon carbon dioxide mixed gas, argon oxygen mixed gas, and argon helium mixed gas are used. Welding wire is often made of flux wire that creates slag and provides an aesthetically pleasing weld, but sometimes solid wire is used.
Tank welding machine surrounds the molten pool with the base metal end and copper lining or refractory lining material, and can perform vertical upward welding while preventing dripping of molten metal, so it can be welded in a single pass (single operation) Welding of thick plates. Its applications include welding of vertical butt joints such as ship side outer panels, bridge construction, storage tanks, pressure vessels, etc.
Tank welding machine is usually used for welding thicker materials such as low carbon steel and medium carbon steel, and can also be used for welding austenitic stainless steel and other metal alloys. The thickness of the plate is 12~80mm the most suitable. If it is larger than 80mm, it is difficult to obtain a sufficient and good protective effect, resulting in pores in the weld, uneven penetration and incomplete penetration. The length of the welded joint is generally unlimited. Single-layer welding is the most commonly used welding method, but multi-layer welding can also be used.

The welding machine for large storage tanks is a kind of tank in which oil, natural gas and other energy sources are stored. Because the tank body is too large, it cannot be shaped at once. It is made of steel plates and spliced together, so a welding machine is required in the splicing process. Although manual welding is the simplest and most direct method, it has high cost and low welding speed. Therefore, the automatic tank welding machine is widely used.
