The heat-resistant conical silicone pipe stoppers are available in 7 sizes for the range of ID Ø 10 to 110 mm. The stoppers can be ordered by the piece.
As a backing gas or test stopper, PSP nylon pipe stoppers are the best choice. As a (low pressure) test stopper, they withstand test pressures of up to 5 Bar, depending on pipe diameter and conditions.
The PurgePlugs® stoppers set includes two nylon stoppers per pipe size between 12 and 110 mm. Indispensable for orbital welding where a pipe system needs to be quickly and hygienically capped.
The aluminium housing of these lightweight PSP pipe stoppers is resistant to various chemicals and salt water. If required, these pipe stoppers are available with heat-resistant rubbers.
Traditional steel PSP pipe stoppers can be used to temporarily shut off a pipe or as a backing gas stopper when welding with backing gas. The prerequisite is that the stopper is placed sufficiently far from the heat source.
The heavy-duty STA350 press plugs for hydro testing are available in various DN sizes with the maximum test pressure varying by diameter, ranging from 4.5 Bar to 30 Bar. The STA350 is fitted with a ball valve as standard.
The stable and robust STA360 press plugs for hydro testing are available in various DN sizes with the maximum test pressure varying by diameter, ranging from 2 Bar to 100 Bar. The STA360 is fitted with a ball valve as standard.
The PlugFast® mechanical stoppers they are designed for applications in harsh conditions such as contact with in chemicals and/or exposure to high temperatures. The orifice in the PlugFast™ stopper makes draining after testing easy.
