STRIKO Verfahrenstechnik – Technical profile of a rupture disc, static mixer and heat exchanger manufacturer

STRIKO Verfahrenstechnik is a German manufacturer of rupture discs, rupture disc holders, burst indicators, static mixers and heat exchangers for viscous or high-viscosity media. In the Philippopoulos S.A. range, the main technical focus is on rupture discs and accessories for pressure protection.

The rupture disc range includes:

• flat metal rupture discs,
• forward acting rupture discs,
• reverse acting rupture discs,
• aseptic rupture discs,
• graphite rupture discs,
• rupture disc holders,
• pre-torqued holders,
• burst indicators and leakage sensors.

A rupture disc is a non-reclosing pressure relief device. It opens at a defined burst pressure and burst temperature, providing rapid relief of pressure. After activation, the disc must be replaced and the cause of the pressure event must be investigated.

Forward acting rupture discs operate under tensile stress. Reverse acting rupture discs operate by buckling or reversal and are often selected for higher operating ratios, vacuum resistance and cycling resistance. Graphite rupture discs are used where corrosion resistance is required. Aseptic discs are used in pharmaceutical, biotechnology, food and beverage applications where hygienic connections and cleanability are required.

The holder is part of the safety assembly. It defines centring, sealing, compression and repeatability of installation. Pre-torqued holders reduce installation errors caused by incorrect flange tightening.

Selection data must include:

• burst pressure,
• burst temperature,
• operating pressure,
• operating ratio,
• gas, liquid or two-phase relief,
• required relief area,
• corrosion conditions,
• back pressure,
• vacuum resistance,
• holder type,
• burst indicator requirement,
• PED, ISO 4126, ASME or project-specific documentation.

STRIKO static mixers and heat exchangers are used where mixing or heat transfer must occur without rotating equipment, especially in viscous media. For these products, pressure drop, viscosity, Reynolds number, material compatibility and cleanability are central design parameters.
