- Có thể sử dụng cho các mối hàn ống, co cút
- Phớt xông khí silicon thể tách rời và được sử dụng riêng biệt như một bộ phận dẫn khí hoặc bịt ống.
- Các cụm chi tiết có thể tháo lắp và sử dụng hoán đổi giữa các size, giúp giảm chi phí
Features and advantages
- Extremely short purge times resulting in valuable cost savings, typical purge times of less than 2 minutes (e.g. an 8″ pipe will purge to below 0.01% oxygen in less than 2 minutes)
- High-quality silicon sealing discs that prevent them tilting or falling over inside the pipe
- UV and temperature resistant up to 330ºC (626ºF) continuously or 450ºC (842ºF) for short periods
- Suitable for purging pipes, elbows and fittings
- The silicon seal units can be separated and used as a gas finger and pipe stopper respectively
- Fully interchangeable and individually exchangeable system, reducing cost of ownership
Nguyên lý hoạt động
Sản phẩm gồm các cặp phớt chặn gắn ở hai đầu khí vào và ra, lắp trên trục dẻo, uốn linh hoạt hoặc trục cứng. Thiết kế giúp đảm bảo
How it works
The gas inlet and outlet are provided with twin sealing discs separated by a flexible, rigid or a spring-type tube. The design guarantees that at least one disc will always remain tight to the pipe wall creating a 100% seal. The discs are UV and temperature-resistant up to 330ºC (626ºF) continuously or up to 450ºC (842ºF) for short periods. The gas is diffused into the chamber via the built-in centred diffuser and exits through the exhaust holes in the secondary twin disc unit.
This extremely short process of gas diffusion provides an equal gas flow and prevents any gas turbulence behind the weld, thereby minimising the risk of oxygen re-entering the welding chamber.
Besides the very short purging time, the double seal system also offers the possibility to cover various nominal pipe diameters by one pair of seals enabling highly economic use of the device. The double seal system can be purchased individually or in kit form for a range of pipe diameters.
