Transportation & Shipping

Many products which exist as a gas under atmospheric pressure are transported and delivered in compressed liquefied form. Although some of these, are considered hazardous including petroleum gas (LPG), propane, butane, while others such as carbon dioxide and liquid nitrogen are not. However, both hazardous and non-hazardous liquids and gasses, transported under pressure, are ideal applications for ZOOK rupture disk for protection against over-pressure conditions.

Compressed gas transported in cylinders is generally transported in three forms including, compressed gas, liquified compressed gas, and cryogenic compressed gas. Often referred to as bottled gas, typical products transported by this method serve the medical, pharmaceutical, food, semiconductor and numerous industrial applications. Because the contents are under pressure and are sometimes hazardous materials, handling bottled gases are regulated. Rupture disks from ZOOK installed in the base of the valve between the cylinder and the valve seat provide safe release of pressure should the internal pressure exceed the mechanical limitations of the cylinder.

Ocean vessels and tankers which have integral containment compartments for transport of petroleum and other liquid products in bulk rely on ZOOK rupture disks to maintain hull integrity should an overpressure condition occur.

Hazardous materials are products that pose a risk to health, safety, and property during transportation. Hazardous materials include flammable and combustible liquids, corrosive chemicals, materials harmful to the environment, municipal, industrial and biohazard waste.

ZOOK rupture disks provide over-pressure protection for bulk liquid containers designed for oceangoing vessels.
