The installation of pipeline construction equipment is one of the necessary parts in the pipe construction solution, and the installation and construction of pipeline construction equipment is a very important stage in project construction. Due to various factors in the project construction, there are many problems in the installation of pipeline construction equipment. To promote the improvement of the quality of industrial pipeline installation, certain measures need to be taken to control the installation quality of pipeline construction equipment to ensure the smooth construction of the project.
Here is the content list:
l Regarding the quality inspection of pipeline construction equipment installation.
l What are the quality control measures in the installation of pipeline construction equipment?
l Regarding the quality control of pipeline construction equipment after construction.
The sequence of installation of pipeline construction equipment is:
Measuring arrangement→cleaning the construction work area; construction road→conveying anticorrosion pipe→processing tank→distributing pipe→preparing nozzle; pipeline assembly→pipe assembly and welding→welding joint inspection→heat shrinkable casing (tape) bushing→ trench excavation →Appearance repair .
After the installation of pipeline construction equipment is completed, quality inspection is required. After pipeline construction equipment is installed and put into use, regular monitoring is required. Generally, radiographic inspection is used to inspect the quality of pipeline installation. This monitoring has a very good effect on the internal inspection of welded joints. It is widely used in the field of construction equipment installation. This method can also be used to make the quality of the pipeline meet the assessment standard.
Before installing pipeline construction equipment, clarify the construction plan of the construction technicians, use GB/T as the standard, and carry out construction in accordance with national standards and specifications; during the installation of pipeline construction equipment, strictly review the drawings for defects to ensure the rationality of the drawings, and the construction unit It is also necessary to make preparations for pipeline installation and construction, pipeline lumber, welding inspection, construction site management, etc.
Strictly follow the relevant requirements of pipeline construction equipment and pipeline construction requirements to improve the quality of construction. In order to ensure the quality of pipeline installation, quality control is required for key parts such as welding materials, welding processes, and welding seams to ensure pipeline construction equipment. Welding consumables, brands, specifications, etc. are required by the plan design, which are consistent with the project construction requirements to ensure the quality of installation.
① After the pipes, accessories and raw materials used for pipeline construction equipment enter the construction site, the supervisors shall check and accept them on site, and store the materials after passing the acceptance.
② Pipe joints and semi-finished products of pipeline construction equipment should be guaranteed not to be damaged during transportation and storage. When unloading, handle with care and not collide with each other; choose a flat place for stacking pipe joints.
③ The storage temperature of the rubber ring of pipeline construction equipment is between -5 and 30 degrees Celsius. It should not be exposed to ultraviolet light source and keep away from the heat source; the rubber ring and the items that easily affect the rubber ring should not be put together. If the pipeline construction equipment is being constructed In winter, hard rubber rings are not allowed.
④ For trench excavation in open-cut pipeline engineering, the section should meet the design requirements of construction quality, the original soil at the bottom of the trench should not be damaged, and the mechanical excavation should reserve a 200-300mm soil layer for manual excavation and leveling, and the bottom of the trench can be soaked by water And frost damage, if there is gravel soil, lime soil to backfill, the trench wall should be leveled to meet the requirements of construction design.
⑤ For concrete construction, when the pipe seat and flat foundation are poured in layers, the flat foundation should be shaved and rinsed; the concrete should be prevented from segregation, and the concrete should be cured after pouring.
⑥ When pipeline construction equipment is installed, visual inspection and internal cleanliness of the pipeline must be inspected.
⑦ The flexibility of pipe joints must meet the design requirements, and the rigidity must also meet the requirements.
⑧ In the stage of backfilling, the backfill height between both sides of the pipe and the top of the pipe before the hydraulic test of the pressure pipeline is greater than 0.5M, and the pressure-free pipeline shall be backfilled after the closed water test and the closed gas test have reached the standard.
After the completion of the pipeline construction equipment, the finishing work will begin. The unit needs to organize personnel to review the material documents involved in the pipeline installation, project reports, etc.; after the completion of the project, debugging and quality appraisal are required, and the pipeline professionals are organized to conduct quality appraisal of the installed pipelines. The dynamic control of the links will protect the completed pipelines.
In the later stage of the installation of pipeline construction equipment, in order to ensure the smooth completion of the project, the quality of the pipeline needs to be tested again to ensure that the pipeline installation does not have problems such as tilt and cracks, the welding parts are of good quality, and the pipeline is unobstructed. In the later period after the completion of the project, it is necessary to sort out each project data and work files involved in the pipeline construction, do a good job of archiving and backup to evaluate the quality of the pipeline, do a good job in risk control, and carry out the acceptance of pipeline construction equipment.
There are many influencing factors in the installation of pipeline construction equipmentt, so reasonable measures need to be taken to monitor and control every aspect of pipeline construction equipment. With the continuous expansion of the pipeline construction equipment construction industry, the use area is also expanding. Due to the importance of pipeline use, it is necessary to control the pipeline installation quality to ensure that the installation quality reaches the ideal standard!

The main features of tank welding machine.
l Reasonable design and free adjustment. Tank welding machines with different discharge frequencies can be selected according to different metal materials to achieve the best repair effect.
l The heat affected area is small. There is no heat input during the instant of cladding, so there is no deformation, undercut and residual stress. No partial annealing will occur, and no need to re-heat treatment after repair.
l The impact of tank welding machine is extremely small. The welding machine overcomes the impact of ordinary argon arc welding on the periphery of the work piece in the welding repair process. It is also possible to repair the work surface with no allowance.
l High repair accuracy. The surfacing thickness ranges from a few microns to a few millimeters, and only needs to be polished and polished.
l High welding strength. Due to the full penetration of the material on the surface of the work piece, a strong bonding force is produced.
l Adopt ring precision control.
How to use a tank welding machine?
l Check the connection
After completing the wiring of the tank welding machine, you must check each installed connector to confirm that it is well connected before starting to operate the equipment. Its contents include:
1. The line connection is correct and reasonable, and the grounding must meet the specified requirements
2. The magnetic work piece gripper shall not have attached metal particles and splashes on its contact surface;
3. The coiled welding cable should be unrolled before use to avoid overheating and insulation damage;
4. When it is necessary to alternately use different lengths of cables, insulating joints should be provided to ensure that useless lengths can be disconnected when not needed.
l leakage
There must not be any leakage of cooling water, shielding gas or engine oil that affects the safety of welders.
l Work suspension
When the welding work is suspended (for example, during breaks), the output terminal of the equipment or welding machine must be turned off or the power supply must be cut off.
l Mobile welding machine
When you need to move the tank welding machine, you must first cut off the power supply at its input end.
l Equipment not used
The metal electrode and carbon electrode must be removed from the welding tongs when not in use to eliminate the risk of electric shock to personnel or conductive objects. The welding tongs must be placed out of contact with persons, electrical conductors, flammable objects or compressed air bottles when not in use. The welding torch of the semi-automatic welding machine must be properly placed when not in use to avoid accidental activation of the gun body switch.
l maintain
All arc welding equipment must be maintained at any time and kept in a safe worki
