Subcategories of Pressure Control and Explosion Protection Equipment

Rupture Disc (Rupture Disc / Burst Disc)

Rupture discs are critical devices that protect equipment from overpressure. They operate instantly when pressure exceeds the allowable limit, preventing damage to tanks, pipelines, and process equipment. Atieh Pardazan Sharif designs these discs according to ASME, API, and ISO standards to ensure fast, reliable, and safe operation.

Flame Arrester (Flame Arrester)

Flame arresters prevent flame propagation into process lines and storage tanks. They safely cool and quench sparks or flames, preventing chain explosions within the system. Their use is essential in storage tanks for flammable materials, vapor and gas lines, and petrochemical units. Atieh Pardazan Sharif provides these devices with heat- and corrosion-resistant materials and optimized hydraulic designs.

Explosion Door (Explosion Door) and Explosion Vent (Explosion Vent)

Explosion doors and vents are designed to rapidly release energy and pressure in case of an explosion, protecting buildings and equipment. These systems are engineered based on precise calculations of explosion load, operating pressure, and type of gas or vapor, and can be installed on tanks, ducts, and process lines. High-quality materials and engineering design ensure rapid and safe operation.

Emergency Relief Vent

Emergency relief vents are designed to manage sudden, unpredictable pressure increases. They activate automatically, preventing damage to tanks and process equipment. Atieh Pardazan Sharif designs and installs these systems in compliance with API 520 and API 526 standards, ensuring personnel and equipment safety.

Breather Valve / Pressure-Vacuum Relief Valve

Breather valves or pressure/vacuum relief valves protect storage tanks from excessive pressure or vacuum. They allow ambient air to enter or exit safely without risking explosion or tank damage. Precision-controlled pressure, corrosion resistance, and easy adjustability provide stable and reliable operation.

Rim Vent Valve and Vacuum Breaker Valve

Rim vent and vacuum breaker valves control internal tank pressure and prevent excessive vacuum or pressure. They are installed in chemical, oil, and gas storage lines and provide complete process safety with corrosion-resistant structures and precise mechanical design. Proper operation extends the life of tanks and ancillary equipment and reduces operational risks.

Gauge Hatch / Thief Hatch

Sampling and gauging valves allow operators to safely sample and monitor tank and process line conditions without interrupting production. They are especially critical in petrochemical units, flammable material storage, and sensitive process lines. Atieh Pardazan Sharif designs these devices with safety, accessibility, and reliable sealing in mind.
