Low Pressure Tanks. Low pressure ia the coatext of tanks means tanks designed for a higher pressure than atmospheric tanks. In other words, these are relatively high pressure tanks, designed to operate from atmospheric pressure up to 15 psig (101.4 kPa). 

Pressure Vessels. High pressure tanks are vessels operating above 15 psig. These are reaHy pressure vessels and the term high pressure tank is basicaHy never used. Pressure vessels are a speciali2ed form of container treated separately from tanks by aH codes, standards, and regulations. 

Understanding how sudden pressure releases can occur is important. They can happen, for example, from ruptured high-pressure tanks, runaway reactions, flammable vapor clouds, or pressure developed from external fire. The proper design of pressure rehef systems can reduce the possibility of losses from unintended overpressure. 

Storage tanks are generally designed based upon the vapor pressure of their contents, and can range from low pressure (API-type) tanks to high pressure tanks for compressed gases or pressurized liquids.

The mandrel can be recoverable, or can be integrated in the finished part, for example, in the inner liner of high-pressure tanks. 

High-pressure tanks—a storage vessel designed to contain material at pressures above 15 psig. 

The formation of polyolefins was first discovered by the occasional and unexpected loss in pressure in high-pressure tanks containing ethylene. The tank did not seem to have a leak so the scientists cut it open and discovered white solid on the walls. Somehow the tanks occasionally contained certain impurihes that initiated free-radical polymerizahon. This was the first successful commercial polymer, and it is stiU the largest-volume polymer. 

This technique is now the primary means of producing ammonia, which can be stored in high-pressure tanks as a liquid and injected into the soil. Alternatively, the ammonia can be converted to a water-soluble salt, such as ammonium nitrate, NH4N03, that is then applied to the soil either as a solid or in solution. The mining of other nutrients, such as phosphorus and potassium, still remains an important endeavor. 

Fig. 10.1. Some common high-pressure tank fittings. The seal in the top three fittings is made by contact between the nipple in the connection and the seat in the outlet. Note the cone-shaped, round, and bullet-shaped nipples for (a), (b), and (c) respectively. The bottom connection (d) is sealed by means of a flat soft-metal gasket. Never attempt to mix outlet and connections between the various designs. Note the grooves on the connection nuts for connections (b), (c), and (d). This groove indicates a fitting with left-handed threads. (Reproduced by permission of the copyright holder, Mathe-son Gas Products, Inc.)...

Divers who ascend too quickly can develop the bends, a condition caused by the formation of nitrogen bubbles in the blood. Treatment involves placement in this high-pressure tank called a hyperbaric chamber, and a slow, controlled change to atmospheric pressure.

Abstract. The present work deals with major technical items related to defectoscopy of metallic materials - in particular, welded joints - which can be considered as constitutive for H-storage high pressure tanks such vessels must be corrosion and pressure-resistant, especially in order to avoid any infiltration by light H-atoms and, in general, H-embrittlement and Stress Corrosion Cracking (SCC) phenomena. 

The Liquid Dispensing Tank. As opposed to high-pressure tanks filled with a highly compressed gas, cryogenic gas tanks hold the liquid form of a gas and are insulated to maintain the cryogenic temperatures necessary to maintain the gas in its liquid state. 

Holographic imaging can also lead to detection of defects and has been used in detection of defects in automobile clutch plates, brake drums, gas pipelines, high-pressure tanks and turbine blades.
