Recommendations for Stationary Boilers which is applicable to pressure vessels.
This often causes seal damage or fatigue failure and subsequent leakage bs 1515 pressure vessel can result in a major accident.
The position of addition of reactants may also be important – sub-surface and directly into an intimate mixing zone within the reactor may result in be minimisation of the generation of reaction by-products.
ASME standards recommend that pumps should be periodically monitored to detect vibration that should normally hs within prescribed limits as determined by the manufacturer. Key parameters for pump selection are the liquid to be handled, the total dynamic head, the suction and discharge heads, temperature, viscosity, vapour pressure, specific gravity, liquid corrosion characteristics, the presence of solids which may cause erosion etc.

Sign into or create your free personal account Sign in via Shibboleth What is Shibboleth? This type of equipment is a potential source of loss of containment.
There bs 1515 pressure vessel three principal methods of sealing the point at which a rotating shaft enters a pump, compressor, pressure vessel or similar equipment:. Some images exist copyright, please respect the copyright of the original author. Double block and bleed valves on fuel lines can be considered.
Consideration should also be given to the consequences of agitation failure in the design of the reaction system. For example, flammable solvents, refrigerants and heat transfer media bs 1515 pressure vessel often be replaced by non-flammable or less flammable high boiling materials. A lined vessel is usually more economical than one built of solid corrosion resistant material. Pumps are particularly vulnerable to mal-operation and poor installation practices. The description atmospheric storage is applied to any tank that vesswl designed to be used within a limited range of atmospheric pressure, either open to the atmosphere or enclosed.
BS – Boiler and Pressure Vessel engineering – Eng-Tips
There are a bs 1515 pressure vessel of functional sub-committees who deal with specific aspects and a large number of technical committees as well as many additional sub committees and working bs 1515 pressure vessel. Reactors are most often considered as pressure vessels and the mechanical design should be in accordance with the codes and standards described earlier. Lightning protection should be provided and guidance is available in BS These units can be either centrifugal or axial flow type.
Assessments should be based on: For relief systems consideration should be given to the implications of the release of reactor contents and containment and control systems may be necessary to prevent a hazardous situation from developing as a result of the discharge of a relief system.
Protection against lightning strikes on process plant located outside buildings is required since lightning is a potential ignition source especially for fires involving storage tanks. This is a typical industry sector standard containing specific guidance on the use of materials of construction for chlorine systems.

Consideration should be given to the possibility of pressure cycling in equipment and subsequent failure of the equipment due to metal fatigue. It occurs primarily at sites where there is a flow restriction or change in direction including valves, elbows, tees and bs 1515 pressure vessel.
The most important characteristics that should be considered when selecting a material of construction are summarised below: The main relevant standard is BS The strength of materials decreases with increasing temperature and therefore the maximum design temperature should take into account the strength of material used for bs 1515 pressure vessel. Value engineering assessment; Energy efficiency assessment; Reliability and availability assessment; Hazard identification and assessment; Occupational health assessment; Environmental assessment.
Heating, cooling, evaporation or condensation may all need to be considered and the equipment designed accordingly to account for the differing bs 1515 pressure vessel.
General corrosion; Crevice corrosion; Corrosion pitting; External corrosion including corrosion beneath lagging; Stress corrosion cracking; Corrosion fatigue. Systems should be in place to ensure that corrective action is taken on the identification of discrepancies between installed equipment and the design intent and to control any deviations from normal operation.
They should be sufficiently chemically resistant to the fluid contained and not be significantly affected by ageing.
Excessive loss of vapours from vent systems may result bs 1515 pressure vessel outbreathing bessel may present a hazard. Published by HSE Books Learn about subscription and purchase options. Any equipment that is to be installed should be designed to withstand the foreseeable temperature and pressure over the whole life of the plant.
It can be applied to a bs 1515 pressure vessel range of unit operations including reactors, distillation and bs 1515 pressure vessel exchange but it may involve different mechanisms and approaches having to be employed to the reaction chemistry and control systems; Substitution – this technique involves replacing a hazardous material or feature with a safer one.
Other factors which require careful consideration include; a means of in-service periodic examination i. Spherical and cylindrical vessels. Nonrefrigerated and refrigerated, American Petroleum Institute, The advice of specialist materials engineers should be sought in the event of difficult applications being identified.
Low pressure storage tanks; Pressure or refrigerated pressure storage tanks; Refrigerated storage tanks.
