What is a viable alternative to using rupture discs for pressure piping?

specifically with respect to pressure relieving devices on PD pumps

The only viable alternative that I know of is a rupture pin valve, which is an environmentally friendly presse reliving device. The valve only has one moving part, the piston. With its elastomer seal, the piston seals the inlet port. System pressure is measured on the face of the piston. The system pressure is then transferred to the piston, which is held in place by the pin. When the system pressure increases to the valve set pressure, the pin will buckle according to Euler’s Law of Compressed Columns. The valve will have a bubble tight seal until the pin buckles, at which time the system will have full bore relief. The valve is easily reset by removing the pressure at the valve, reseating the piston by depressing the piston stem, removing the buckled pin, and installing a new pin. The pin is external and is not affected by fluid corrosion or temperature.
