Pipe weld purging system for the highest welding quality

Reduction of the residual oxygen content to a minimum

The inflatable forming system is characterised by its functionality: the reduction of the residual oxygen content in the forming chamber to a minimum in a short time. In contrast to conventional systems, ASS®-Prime values around 5 ppm. This enables significantly improved quality at the root of the weld seam and effectively prevents discolouration and other undesirable effects.

Efficient and time-saving processes

ASS®Prime was specially developed for efficient and time-saving processes. Thanks to the increased gas flow and the optimised design, the forming chamber is purged in the shortest possible time, reducing the purging time by up to 50% compared to conventional systems. In addition, the easy handling of the system leads to further time savings.

Example:

This became apparent with a customer who works with moulding in the food industry. Using the ASS®-Prime forming system compared to the previously used forming system, the forming time was reduced from one hour to 30 minutes. In this comparison, a time saving of 50%. This fact convinced the customer that the design of the ASS®-Prime forming system has achieved a "small" revolution in the field of forming with the impact forming method. The result is considerable cost savings and improved welding quality.

Flexible application for individual requirements:

ASS®-Prime offers flexibility and adaptability to a wide range of requirements. The side of the gas supply and the "blow-out" can be designed variably. The length of the "supply line" can be selected between 10m, 20m and 30m. The primary bag and secondary bag are connected with a 30cm or 60cm long high-quality hose. If, for example, a longer connecting hose is required when preheating pipes, this connecting hose can also be extended to meet the requirements. The sizes of the forming bags are available for internal pipe diameters from 50mm to 637mm. In addition, the bags can have different sizes, as is the case with REDUCTIONS, for example.

One system for 6 applications

With the 6 application options that have been developed, the "blow-out at the back" & "blow-out at the front" are about the possibility of adapting the blow-out direction to the respective situation.

Highest quality and durability:

ASS®-Prime is made from high-quality materials such as neoprene, which is significantly more resistant and suitable for increased pressure compared to fabric bags made from other materials on the market. This ensures a long service life and minimises the risk of damage.
