Press connection technology vs traditional jointing methods
Industry Insight: Supplied by Viega UK
With the summer shutdown upon us, Viega UK explores the benefits of press connection technology vs traditional jointing methods.
To demonstrate the time-saving and installation speed of press connection technology, Viega commissioned independent testing by BSRIA under laboratory conditions, where their Megapress press connection system was compared to three alternative pipe connection methods.
Viega Megapress is the first press system for thick-walled steel that connects pipes with various surfaces up to 4” in seconds without requiring a hot works permit. The range is available at all Smith Brothers locations and online here.

Benefits of Using Viega Megapress vs. Traditional Welding
In the realm of the highly time-bound summer maintenance programmes, efficiency and reliability are paramount. Traditionally, welding, threading and screwing have been the go-to methods for joining steel pipes. However, press connection has emerged as a strong contender, offering distinct advantages in terms of time and cost savings. This report explores the benefits of using press connection technology compared to traditional methods.
Speed and Efficiency
Installation Time: One of the most significant advantages of press connection jointing over welding is the drastic reduction in installation time. Welding requires meticulous preparation followed by the actual welding process, which is time-consuming and requires cooling periods. In contrast, Megapress fittings can be installed in a fraction of the time. The cold press technology allows for quick connections without the need for welding, threading, or grooving, making it a highly efficient choice for both new installations and repairs.
No Hot Works: Welding often necessitates specific conditions, such as a controlled environment to prevent contamination and to ensure safety due to the open flame involved. Press connection systems do not require such stringent conditions, allowing installations to proceed without delays caused by environmental constraints. This advantage is particularly beneficial in existing buildings where creating a welding-safe environment can be challenging and disruptive.
Cost Savings
Labour Costs: The saying goes that time is money, and the efficiency of press connection system tested (Viega Megapress) translates directly into labour savings. The reduced installation time means that projects can be completed faster and more efficiently, decreasing not only the number of man-hours but also less labour required onsite. This is especially important in large-scale projects where labour costs constitute a significant portion of the budget. Moreover, the skill level required to operate a Pressgun is generally lower than that needed for proficient welding, allowing for a more flexible and cost-effective workforce.
Reduced Downtime: In commercial and industrial settings, downtime can be costly. The faster installation time press connection jointing offers means that systems can be up and running quicker compared to traditional install methods. This minimisation of downtime is crucial in environments where operational continuity is essential, such as hospitals, manufacturing plants, and commercial buildings.
Safety and Reliability
Enhanced Safety: Welding poses significant safety risks. These risks necessitate comprehensive safety measures and protective equipment, which add to the overall cost and complexity of the project. Press connection systems eliminate these hazards, offering a safer alternative for workers. The cold-press method used does not involve heat or open flames, significantly reducing the risk of injury and enhancing overall site safety.
Consistent Quality: The reliability of the tested Megapress system is another critical benefit. Welding requires a high level of skill to ensure consistent, high-quality joints. Variations in technique or environmental conditions can lead to weak or defective welds. Press connection fittings, however, provide consistent and reliable connections with every press, reducing the likelihood of leaks or failures. This consistency is crucial for maintaining the integrity of piping systems over the long term.
Conclusion
In summary, press connection systems offer significant advantages over traditional welding methods for steel pipes, particularly in terms of time and cost savings. The speed and efficiency of installation, coupled with reduced labour and material costs, make press connection an attractive option for many projects. Additionally, enhanced safety and consistent quality further bolster its appeal. As the construction and maintenance industries continue to seek ways to improve efficiency and reduce costs, especially during the timebound school shutdown window, press connection systems and notably Viega’s tested Megapress systems stand out as a robust solution for steel pipe installations.
