Mechanical Seal Support System Welding: Common Challenges and How Automation Solves Them

Introduction: Why Welds are More Important Than You Think

The mechanical seal support systems are the ones that ensure efficient functioning of the pumps and compressors. They are the barriers that stop breaking down seals, reducing the risks of a plant that may have to shut down for repairs. If the whole process is safe, and it saves a lot of money. There are many things in a system that have a significant role to play, one of which is tubes. In the system diagram, the connecting parts based on the different branches are the welds that are really essential. Imagine a plant that is losing its production not due to broken equipment, but because of just one bad welding job that led to a leak, system failure, and possibly a major accident.

What is a Mechanical Seal Support System?

The systems are designed to supply the mechanical seal with clean, cool, and properly pressurized fluid. This fluid also lubricates the seal and cools it down by taking away heat. The main job of the seal support system is to create the best environment for the seal to work in, thus the equipment will function for a longer period of time, and no costly failures will occur. These are the networks of pipes, valves, and instruments that work together to keep the main equipment running.

Why Welding is So Essential

The pressure relief features of a seal support system increase the risks of leaking. The need for high-quality connections is, therefore, paramount in shielding the leakage of high-pressure lines. In some instances, even a single leak in a joint connection can completely compromise the functional integrity of the entire system. Recommended industry standards like API 682 emphasize the importance of making high-quality connections. Therefore, the quality of mechanical seal support system welding should definitely be one of the plant’s top priorities.

The Problem: Common Issues with Manual Welding

Until recently, the only way to build these systems was manual welding. But, it has many problems that endanger safety and life. Often, we have encountered the same problems why these projects have failed. Engineers, as well as maintenance, always try to say something succinctly about the main problem of getting the correct and consistent, high-quality welds. Those problems are the top reasons for the unreliability of the plant and, consequently, associated costs. Reliability in manufacturing a mechanical seal support system is often outside the manual welding capabilities.

Challenge 1: Variations in Quality and Human Error

In manual welding, there may be variations in the quality of the weld from different welders, and, in fact, even from the same welder during a long shift. Factors such as being tired, working in an uncomfortable position, or having poor lighting can greatly affect the final weld. The result is the system sustainability that is questionable because of the added risk of unknown early failures.

Challenge 2: Material and Contamination Problems

Seal support systems are mostly made of thin-walled, specially alloyed tubing, or stainless steel. But not the type that is easy to weld. Manual welding these materials is very difficult and makes it easy to burn through the wall, or warp the tube. It can be hard to get an inside tube properly purged with an inert gas too. If it is not done right, then the inside of the weld can become oxidized. Sugar is a term that this is often referred to. These oxides are liable to break off and contaminate the seal fluid. This leads to the quick failure of the mechanical seal.

Challenge 3: Absence of Records and Documentation

It is almost impossible to gain exact data for a manual weld. You know who welded it, but you do not know the exact settings used. This is a big problem for quality control. For a well-run Quality Assurance plan, it is sometimes necessary to have detailed weld logs for all joints. Hand coding these logs is slow and often incorrect. The absence of logs means that it may only be possible to make guesses at what the root cause of a fault is.

Challenge 4: Skilled Labor Shortage and Safety Risks

Critical systems welding on high-purity needs requires a very high level of skill. Certificate welders that are capable of this work are few and far between and they often cost a lot. This can indeed delay the project. Besides, tight spots while welding near equipment can be hazardous. Workers get exposed to the electric arcs, heat, and fumes in awkward positions.

The Solution: Circular Welding Automation

In contrast to these setbacks the smart industries have introduced automation. Automated circular welding has become the most favorable option for constructing and servicing these essential systems. Circular welding is a robotic process. The welding torch stay fixed while the product rotate to be welded. There is a rotating chuck to hold the workpiece and a PLC to store the welding parameters. There are also orbital welder which welding torch rotates while the workpiece stay fixed. But orbital welder is a bit difficult to have the root pass welding by automation. There are certain limitations. Therefore, the rotating chuck type automated welding machine is currently the ideal solution for mechanical seal support system welding. The need for welds that were perfect and identical with each patch was then a huge barrier for manual welding, however, the automation welding is the most reliable option for the mechanical seal support system welds. The highest quality seal support systems often incorporate advanced construction methods to guarantee their reliability. Automation is a major part of this process.

Manual vs. Automated Welding: A Side-by-Side Look

Automation advantages are clear when you view manual and automated processes next to each other. This graph shows the difference in a direct comparison for key factors in mechanical seal support system welding which is almost at all points better for automation.

How Automation Directly Solves the Major Issues

Automated welding does not only optimize the process. It addresses the main critical problems in manual welding. It encloses distinct technical benefits that prompt to manufacture safer and more reliable systems. The automated process of mechanical seal support system welding is so precise that there is neither guesswork nor risk in connections.

Solving Consistency: The Power of the Program

In automated welding, the welder settings are controlled by settings stored in the program. The program sets the electric current, travel speed, and gas flow. The machine runs this program perfectly at every single weld. This removes all human factors. The first and last weld of the day are absolutely the same. Watching a demo of autoamted welding in action greatly helps to visualize this programmed precision work.

Solving Quality: Perfect Welds, Inside and Out

For pipe and pressure vessels welding, it’s also important to inert gas free of oxidants during the weld. This process, along with automated gas purging inside the tubes, completely removes the oxidation that is responsible for “sugaring.” The result is a perfectly smooth weld on the inside of the tube. There are no cracks or pits that dirt to hide into. The ultimate goal of any mechanical seal support system is to maintain the fluid totally pure. The best way to achieve this is the automated welding at the construction stage.

Solving Records: Data on Every Weld

Modern automated welding systems are also data recorders. They will make a detailed digital log for every weld made. This log will contain the settings you used, the date, time, and operator ID. This data can be printed or stored for quality control records. It can be linked to a specific weld on a system drawing. This ensures full records which are very important in regulated industries and for maintenance in future.

Solving Labor & Safety: Better Skills and Remote Operation

A trained operator can produce welds that meet the highest quality standards. This helps to solve the skilled welder shortage issue by utilizing the staff properly. The process is also safer. The operator only need to upload and unload the products. Then, he/she can run the weld from a safe distance using a remote control. This greatly reduces risks to workers.
