Serviceability limits

For any given appHcation of any type of valve, temperature, pressure, and corrosivity must be considered in the same manner as for the piping system itself. Valve vendors specify the temperature, pressure, and general service limitation for their valves and these are indicated in the manufacturers catalogs. [Pg.57]

The standard ASTM PCE test is relative and used extensively only for alumina—siUca refractories and raw materials (see Table 5). However, the upper service limit is generally several hundred degrees below the nominal PCE temperature because some load is generally appHed to the refractory duriag service. In addition, chemical reactions may occur that alter the composition of the hot face and therefore the softening poiat. The relationship between PCE numbers and temperature is described ia ASTM C24.

When the temperamre is lowered, rubbers become stiff and brittle. All rubbers eventually stiffen to a rigid, amorphous glass at the glass transition temperature (Tg). This temperature also indicates the low-temperature service limit of the rubber. Tg values are dependent on the structure, degree of cross-linking (vulcanization) and isomeric composition of the rubber. [Pg.580]

Federal drinking water standards for cyanide have been withdrawn and are not included in the latest publication. The Public Health Service limit for drinking water had been 200 ppb. Whether the limit was expressed as free or total cyanide was in question at the time. The fresh water aquatic cyanide criterion is 3.5 ppb as a 24-hour average, not to exceed 52 ppb at any time.

Liner types available are suitable for a wide variety of chemical services, including acids, alkalies, and various solvents. All liners are permeable to some degree, and manufacturers use various methods to vent gas out of the interspace between the liner and casing. All plastics are subject to environmental stress cracking (ESC). ESC can occur even when the liner is chemically resistant to the service. Lined pipe manufacturers should always be consulted regarding liner selections and service apph-cations. Also consult manufacturers regarding vacuum service limits. [Pg.105]

Respirators provide protection against inhaling harmful materials. Different types of respirators may be used depending on the level of protection desired. For example, supplied-air respirators (e.g., a self-contained breathing apparatus) may be required in situations where the presence of highly toxic substances is known or suspected and/or in confined spaces where it is likely that toxic vapors may accumulate. On the other hand, a full-face or half-face air-purifying respirator may be used in situations where measured air concentrations of identified substances will be reduced by the respirator below the substance s threshold limit value (TLV) and the concentration is within the service limit of the respirator (i.e., that provided by the canister). [Pg.768]

In addition to scheduling against compute nodes, the Resource Management layer should provide tools to locate and advertise services. The service location protocol4 (or SLP) provides a capability to dynamically locate services that meet desired criteria. Since a computational environment involves not only scheduling across compute nodes but also potentially the need to dynamically connect to data providers and other service elements, the SLP protocol provides an important interface to flexibly locate and connect to distributed network services, limiting explicit coupling within the system.

The first ductile-iron -valves did not comply with API standard 600 but did meet ANSI B16.5. Many petro-chemical plants and refiners are now interchanging ductile-iron valves with steel valves with a temperature service limit of 600° F. [Pg.330]
