Statutory documents—These are required in many countries for obtaining permission to erect and hydro-test (and for future reference/records of the purchaser). [Pg.319]

An improperly conducted hydro-test creates 35,000 more unanticipated repairs. [Pg.64]

The destmctive hydraulic forces of mild-mannered water were displayed in a classic style on a summer evening in 1996. A Gulf Coast chemical plant had just rejuvenated a recovery tank and started a hydro-test when things went wrong. The poorly executed test added 35,000 to the repair costs. Other than embarrassment, no one was injured. In the previous 3 weeks this tank had received repairs consisting of a new floor and new walls in the lower section. [Pg.64]

The mechanics in this area wanted to do a good job and this incident occurred. How can you impress upon the craftsmen the weaknesses of low-pressure tanks The maintenance superintendent in this area wanted practical training to reduce the probability of a repeat. Concerned supervision scheduled 100 mechanics in this section of the plant to a tender tank presentation patterned after the Institution of Chemical Engineers Hazard Workshop Module The Hazards of Under and Over-Pressurizing Vessels [5]. Procedural changes for hydro-tests were also made. [Pg.68]

Process engineers who have requirements for low flow rates of chlorine can purchase chlorine in 150 pound and one-ton cylinders. These containers are veiy robust and industries have safely used them for decades. The one-ton cylinders are 2 /2 ft. (0.75 m) in diameter and just under 7 ft. (2.1 m) long with extended cylinder walls to protect the valves. Chlorine ton-cylinders are hydro-tested at 500 psig (3450 kPa gauge). [Pg.73]

Hence, a crack that is discovered after hydrotesting can grow 2.25 times its original size before causing failure. This fact illustrates the importance of hydro-testing and is based on a hydrostatic temperature that is the same as the lowest operating temperature of the vessel. [Pg.48]

The second type of pressure test is a strength or hydro test. It is used when the equipment has been modified, say by having some welding done on it, or when structural repairs have been made. Strength test pressures are generally above the equipment or system normal design pressures or relief valve set pressure. [Pg.33]
