The debate on whether press fit will replace welding in the next two years has been a hot topic in the piping industry. Both welding and press fit connections have advantages and disadvantages, but press fit is gaining momentum due to its numerous benefits.
Press fit connections are becoming increasingly popular in the piping industry with one of its most significant advantages over welding being its speed and cost-effectiveness. Press fit is more than 10 times faster than traditional welding methods, translating into reduced labour costs and increased productivity.
Press fit does not require hot work permits, making installation easier and more economical. This means that press fit connections can be installed quickly without shutting down an entire system for an extended period.
Another advantage of press fit connections is their ease of installation. Since no specialist skills are required to install press fit connections, it can be done by a wider range of technicians without the need to hire expert welders. This significantly reduces the time and resources required to install piping systems. Moreover, press fit connections eliminate the need for extensive preparation work that is necessary for welding. This includes cleaning, grinding, and preheating, which can add to the total cost and time of a project.
In addition to being faster and less expensive than welding, press fit also provides superior reliability. Since no heat is involved during installation, there is no risk of warping or thermal fatigue compared to welding. Press fit, originally copper, has been in use in Europe since the 1960’s and has grown to be the system of choice. Press fit is the rule, not the exception, with welding only utilised in applications where it’s absolutely necessary.
In terms of durability and reliability, press fit connections are superior to welded connections. Press fit connections are designed to expand and contract with temperature changes, reducing the risk of leaks and failures.
Press fit also offers a higher level of safety than other installation methods. The process is completely free of any hazardous fumes, flames or by-products, making it safer for both the installer and the environment. Press fit piping systems are an environmentally friendly option that helps to conserve natural resources while still providing a reliable, secure connection. The process also eliminates the need for dangerous tools and materials, such as soldering irons or adhesives.
However, welding still has its place in the piping industry, particularly when it comes to food and beverage transfer lines, high risk and critical systems, and large pipe over 6”. Welding allows for greater design flexibility and enables the creation of complex piping structures that may not be possible with press fit connections alone.
Overall, while welding is still necessary for complex structures, press fit connections are becoming increasingly popular due to their simplicity, speed, and reliability. With no hot work permits, press fit is becoming the preferred choice for many piping systems, with its quick and easy installation and increased level of safety. While it is unlikely that press fit will ever completely replace welding in the next two years, it is clear that press fit in Australia is rapidly gaining popularity and is set to become an essential part of the piping industry as it is in Europe.
