Provisions

Although Division 1 has, in effect, three classes of vessels (fully radiographed, spot radiographed and no radiography) with three stress levels. Division 2 has only one class—all main seams must be fully radiographed. A number of provisions of the Division 2 code are noteworthy. [Pg.103]


The data base contains provisions for a simple augmentation by up to eight additional compounds or substitution of other compounds for those included. Binary interaction parameters necessary for calculation of fugacities in liquid mixtures are presently available for 180 pairs. [Pg.5]

The best way to deal with a hazard in a flowsheet is to remove it completely. The provision of safety systems to control the hazard is much less satisfactory. One of the principal approaches to making a process inherently safe is to limit the inventory of hazardous material, called intensification of hazardous material. The inventories we wish to avoid most of all are flashing flammable liquids or flashing toxic liquids. [Pg.262]

Beam pumping and electric submersible pumps (ESP) require a source of power. On land it may be convenient to tap into the local electricity network, or in the case of the beam pump to use a diesel powered engine. Offshore (ESP only) provision for power generation must be made to drive down hole electric pumps. [Pg.259]

Initially, if operating costs can be divided based on production throughput, the satellite development project may look attractive. However, the unit costs of the declining host field will eventually exceed income and the satellite development may not be able to support the cost of maintaining the old facilities. If the old facilities can be partly decommissioned, and provision made for part of the abandonment cost, then the satellite development may still look attractive. The satellite development option should always be compared to options for independent development. [Pg.364]

Two main types of harmonised standards can be distinguished the product standards and the horizontal standards. The latter, as their denomination indicates, contain issues of a horizontal nature, e.g. for materials or provisions relating to welding or welder approvals. These standards should be formulated in such a way as to be self-sufficient. That means it should be possible to apply them without having to use individual product standards. [Pg.938]

Finally, under the heading Specific pressure equipment requirements specific requirements are set out for equipment with a risk of overheating, for piping and, last but not least, specific quantitative requirements which set out a series of safety factors for certain pressure equipment. These latter provisions apply as a general rule which means that a manufacturer or a harmonised standard may deviate from these factors if it can be demonstrated that appropriate measures have been taken to achieve an equivalent level of safety. [Pg.942]

Comparison of the requirements and provisions of GOST 8.010-90 and terms of ISO 8402 1994 shows identity of procedures being used and we can note that these procedures are harmonised. [Pg.962]

Common rules and norms of metrologieal assuranee are specified in standards of National system for traceability assurance whieh develop and give eonerete expression to the provisions of the law. [Pg.963]

This difference looks large enough to be diagnostic of the state of the adsorbed film. However, to be consistent with the kinetic derivation of the Langmuir equation, it was necessary to suppose that the site acted as a potential box and, furthermore, that a weak adsorption bond of ifi corresponding to 1 /tq was present. With these provisions we obtain... [Pg.613]

One of us, ACA, also wishes to thank Dr David King for his provision of space, time, and a fine scientific atmosphere during a two month sabbatical leave at Imperial College, which aimed out to involve considerable work on tliis... [Pg.1224]

The autliors would like to tliank Jacek Lipkowski, Ben Ocko, Klaus Wandelt and tlieir coworkers for tlie provision of tlieir data for publication in tliis article. [Pg.2755]

An elementary account of the subject has been given in the previous Section. For the fractional distillation under diminished pressure of liquids diflfering only slightly in boiling point, a firactionating column (see Sections 11,15 and 11,17) must be used. Provision must, of course, be made for the insertion of a capillary tube into the fiask containing the mixture. This can be done by any of the following methods —... [Pg.119]

Stoppers. Those fitted with 514,519, and 524 cones are useful sizes. Stoppers with flat heads are to be preferred, since they may be stood on end when not in pse, thus avoiding contamination of the ground surface. An additional refinement is the provision of a finger grip as in Fig. II, 56,1. [Pg.212]

More recent versions of this type of probe include some refinements, such as the provision of a wick to aid evaporation of the solvent and matrix from the probe tip (Figure 13.5). Such improvements have allowed greater flow rates to be used, and rates of 1 to 10 ml/min are possible. For these sorts of low flow rates, minibore LC columns must be employed. [Pg.85]

If the events are not independent, provision must be made for this, so we define a quantity called the conditional probability. For the probability of a head given the prior event of a head, this is written Ph/h> where the first quantity in the subscript is the event under consideration and that following the slash mark is the prior condition. Thus Pj h probability of a tail following... [Pg.454]

Fertilization of ponds to increase productivity is the next level of intensity with respect to fish culture, followed by provision of supplemental feeds. Supplemental feeds are those that provide some additional nutrition but caimot be depended upon to supply all the required nutrients. Provision of complete feeds, those that do provide all of the nutrients required by the fish, translates to another increase in intensity. Associated with one or more of the stages described might be the appHcation of techniques that lead to the maintenance of good water quaUty. Examples are continuous water exchange, mechanical aeration, and the use of various chemicals used to adjust such factors as pH, alkalinity, and hardness. [Pg.16]

Provision ofHve foods is currently necessary for the early stages of many aquaculture species because acceptable prepared feeds have yet to be developed. Algae is routinely cultured for the early stages of moUuscs produced in hatcheries. Once the moUuscs are placed in growout areas, natural productivity is depended upon to provide the algae upon which the shellfish feed. [Pg.20]

Chemical Conversion. In both on-site and merchant air separation plants, special provisions must be made to remove certain impurities. The main impurity of this type is carbon monoxide, CO, which is difficult to separate from nitrogen using distiHation alone. The most common approach for CO removal is chemical conversion to CO2 using an oxidation catalyst in the feed air to the air separation unit. The additional CO2 which results, along with the CO2 from the atmosphere, is then removed by a prepuritication unit in the air separation unit. [Pg.87]
