In recent years, large-scale pipeline projects have started one after another, and the level of mechanical equipment of pipeline construction solutions has been steadily improved. However, the management of pipeline construction equipment on the construction site has not kept up with the speed of pipeline engineering and mechanical equipment updates, resulting in a high rate of equipment failure and maintenance on the construction site. High cost, low technical performance and low utilization rate. In response to these situations, explore standardized maintenance in the management of pipeline construction equipment.
Here is the content list:
l Regarding the maintenance status of pipeline construction equipment at the construction site.
l What are the specific measures to achieve standardized maintenance of pipeline construction equipment?
l How can companies ensure the effective implementation of pipeline construction equipment maintenance procedures?
l Objective conditions cause pipeline construction equipment maintenance to be unable to be carried out normally. Pipeline construction has a large geographic span, harsh construction environment, and increased equipment component wear, which directly affects the stability and reliability of the equipment, causing the mechanical equipment to lose basic performance and fail to operate normally. In addition, the current project schedule is very tight. In order to catch up with the schedule and grab the schedule, it is difficult to keep up with the daily maintenance of pipeline construction equipment.
l Subjectively neglect.The subjective factor that causes the on-site pipeline construction equipment maintenance to be unable to be carried out normally is that the relevant units and management personnel do not pay attention to the equipment management. In many construction companies, the management of the company, project management, and construction crews do not pay much attention to the management of pipeline construction equipment, believing that the equipment is just a tool for wear and tear during the construction process, which emphasizes use rather than maintenance. Many construction projects and construction units arbitrarily extend the maintenance cycle of pipeline construction equipment, reduce the grade of accessories and lubricants, so that the overhaul cycle of the engine is shortened due to human factors, project maintenance costs increase, and the cycle of equipment failures is prolonged. The technical performance of pipeline construction equipment has severely declined.
l Weak technical management capabilities.The quality of equipment maintenance has declined. First of all, many on-site management personnel's understanding of on-site maintenance of pipeline construction equipment is still at the level of "replacement of the three oil filters", and the maintenance of the engine, chassis and working devices is not included in the pipeline construction equipment. Maintenance plan in progress. Secondly, the equipment operators and maintenance personnel do not have a high level of basic skills and cannot complete the overall overhaul of pipeline construction equipment with high quality.
Repair and maintenance of pipeline construction equipmentt is very important. First of all, we must regularly check, maintain and replace vulnerable parts. WINCOO will provide manuals with the machine, such as high-performance pipeline construction equipment, automatic pipeline construction equipment, small pipeline construction equipment, high-precision pipeline construction equipment, easy-to-maintain pipeline construction equipment, etc. The following are specific measures:
① In view of the low maintenance quality of pipeline construction equipment, by compiling comprehensive, meticulous, and highly operable procedures, not only can we clarify what tasks the pipeline construction equipment operators and maintenance personnel need to do daily maintenance and secondary maintenance, but also tell them How to work.
② While compiling maintenance procedures for pipeline construction equipment, the company also compiled checklists for standardized maintenance and management of various types of pipeline construction equipment, making it the main basis for management departments at all levels to inspect pipeline construction equipment, and unify inspection standards and assessment scores. Standards to facilitate the recording, filing and review of equipment inspections and inspection results.
① Personnel training. Strengthen the learning and training of pipeline construction equipment supervisors,managers, and maintenance personnel to change their concepts, fully understand the importance of maintenance to the use of equipment, and cultivate long-term perspectives and implementation of pipeline construction equipment maintenance, and completely avoid the first phase The situation where the project "eaten" a batch of pipeline construction equipment. Through regular learning and training, the standardized equipment maintenance procedures are deeply rooted in the hearts of the people, and become the working guidelines and working habits of operators and repairers, rather than the work requirements of the superior management department. Through learning and training, to a certain extent, the sense of responsibility and dedication of managers at all levels has also been improved.
② Innovate the system of deciding people and machines. In order to mobilize the enthusiasm of equipment operators to rationally use pipeline construction equipment, earnestly maintain pipeline construction equipment, and sincerely care for pipeline construction equipment, the company strictly implements the system of determining personnel and equipment, and integrates the personnel and equipment management information system to control the attendance and equipment of the operators. The intactness of the pipeline construction equipment is linked together, and the man-hours for equipment maintenance are included in the actual man-hours of the operator.
① Increase the intensity of rewards and punishments for pipeline construction equipment inspection. In order to ensure the implementation of the standardization of pipeline construction equipment on-site maintenance, the company pays special attention to the intensity of inspection rewards and punishments for pipeline construction equipment when revising the management system.
② Link the maintenance of pipeline construction equipment with bonuses. In order to motivate the construction unit to use and maintain the pipeline construction equipment, the project department regards equipment maintenance as an important assessment index when formulating the economic responsibility system assessment, guiding the construction unit to use the maintenance pipeline construction equipment rationally, controlling the construction progress and avoiding the problem to the greatest extent.
In order to ensure that pipeline construction equipment maintenance procedures can be effectively implemented, the company has formulated corresponding management systems and adopted specific measures to supervise the implementation of these systems.
l Divide maintenance responsibilities. In the management system, the corresponding responsibilities of equipment operators, pipeline construction equipment maintenance personnel, unit equipment managers, and project pipeline construction equipment managers are clarified, and these responsibilities are written into the maintenance procedures manual of each type of equipment, so that all levels of pipeline construction equipment Managers can see what they should do every day and how to record their work in the maintenance procedures.
l Promote standardized pipeline construction equipment maintenance procedures. Implement standardized equipment maintenance organization processes in each construction project to ensure smooth equipment maintenance channels and optimize the maintenance force of the entire project.
l Establish a professional maintenance team. The project department mobilizes skilled fitters, electricians, and repairers to form a professional maintenance team, which is conducive to the unified scheduling of maintenance forces for the project, and ensures low failure rate and high utilization of pipeline construction equipment.

What is the operation method of tank welding machine?
(1) Left welding method (right→left): small residual height, large width and small splash, which is easy to observe the welding seam, the welding process is stable, the gas shielding effect is good, but the depth of dissolution is shallow.
(2) Right welding method (left→right): The remaining height is large, the width is small, and the splash is large, which is convenient for observing the molten pool and the depth of the molten metal.
(3) Gun delivery method: zigzag swing.
(4) Flat fillet welding does not swing or swing slightly.
(5) The vertical angle is welded upward, and the triangular gun is used.
(6) Welding torch transition: stay on both sides of the molten pool and transition at the front 1/3 of the molten pool.
(7) Gun angle: perpendicular to the weld bead, at an angle of 80-90° along the direction of the gun.
(8) Test plate: the gap is 2.0-2.5mm, and the arc starting point is slightly smaller than the arc ending point. No blunt edge, anti-deformation 1°.
(9) To prevent defects: prevent the angle from melting - burn through the angle. No fusion between layers - pay attention to the gun angle.
The direction of the arc axis of the tank welding machine is perpendicular to the direction of the penetration depth of the weld. During welding, a water-cooled copper slider is used on the front of the weld, and a water-cooled gear row (or pad) is used on the back of the weld. The flux-cored wire is fed into the weldment and in the groove formed by the stopper, the four sides of the molten pool are constrained to realize single-sided welding and double-sided forming at one time. Tank welding machine is a high-efficiency welding technology and equipment.
In recent years, the promotion and application of tank welding machine in engineering has achieved good results, and in-depth research on the fusion welding mechanism of gas-electric vertical welding technology. Tank welding machine has good welding quality, high deposition speed and low comprehensive cost, which provides a broad prospect for the popularization and application of this efficient automatic welding technology and equipment.

Product performance characteristics of tank welding machines.
EGW vertical gas-electric tank welding machines are highly efficient automatic welding equipment, which can control the improvement of the welding frame according to the current feedback closed loop. In a water-cooled forced welding seam, the main feature of a forming is the thickness from 10mm to 50mm.
Automatic control of the molten pool level of tank welding machines and automatic adjustment of wire drawing length. Small size, light weight welding frame and easy to update flexible modularization, easy to use. Widely used in petroleum, chemical, blast furnace thick plate welding and shipbuilding industries.
Tractor tank welding machines are mobile units that can be easily transported to any workstation and are suitable for fillet and flat seams. The modular design makes it easier to expand the units with additional equipment, namely the flux supply unit and the flux recovery unit. For each tank welding machines welding process, suitable components can be combined in the best way.
Specific structural characteristics of tank welding machines.
The basic structure of the exhaust pipe ring welding machine.The assembly of the automatic welding machine is mainly composed of a pulley guard, a transmission mechanism, an observation window, a platform, a guard, and a rotating clamping mechanism.
ACL-200's small automatic welding machine specifications.Aiming at the diameter of the duct in the aero-engine is usually within φ30mm, a small automatic ring welder with the model ACL-200 produced by the American MK company is selected. Tank welding machines are mainly used for butt welding of stainless steel, carbon steel, aluminum alloy and other pipes, and welding of pipelines and pipe joints. The welding range is the outer diameter of the catheter φ6~φ50mm.
Welding technical characteristics of tank welding machines.
Cleaning and tack welding before tank welding machines. Grind the inner and outer burrs of the tube end to make the tube end flush without burrs, and wipe it clean with alcohol. Manual tungsten argon arc welding is used for positioning.If tank welding machines use inappropriate positions, the position of the welding point will deviate from the neutral line of the welding butt surface.
Because the shape of the girth welding seam is relatively regular, the tack welding point that deviates from the weld cannot be covered by the normal weld, resulting in tack welding The points are on the edge and outside of the weld, making the weld surface poorly formed. If the positioning method is adopted, this kind of situation can be effectively avoided!
