ASTM D7863-17 评估液体对流传热系统的标准指南

5.1 The reported values of convective heat transfer coefficients are somewhat dependent upon measurement technique and it is therefore the purpose of this guide to focus on methods to provide accurate measures of heat transfer and precise methods of reporting. The benefit of developing such a guide is to provide a well-understood basis by which heat transfer performance of fluids may be accurately compared and reported. 5.2 For comparison of heat transfer performance of heat transfer fluids, measurement methods and test apparatus should be identical, but in reality heat transfer rigs show differences from rig to rig. Therefore, methods discussed in the guide are generally restricted to the use of heated tubes that have wall temperatures higher than the bulk fluid temperature and with turbulent flow conditions. 5.3 Similar test methods are found in the technical literature, however it is generally left to the user to report results in a format of their choosing and therefore direct comparisons of results can be challenging. 1.1 This guide covers general information, without specific limits, for selecting methods for evaluating the heating and cooling performance of liquids used to transfer heat where forced convection is the primary mode for heat transfer. Further, methods of comparison are presented to effectively and easily distinguish performance characteristics of the heat transfer fluids. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

EN 12178:2016 制冷系统和热泵-液位指示装置-要求,试验和作标记

This European Standard specifies safety requirements, safety factors, test methods, test pressures and marking of liquid level indicating devices, referred to throughout this standard as "level indicators", for use in refrigerating systems and heat pumps. It applies to devices connected to refrigerant vessels (e. g. on high-pressure liquid receivers, intercoolers and low-pressure receivers) and to devices connected to other parts of a refrigerating system (e. g. oil-level sight glasses on a compressor). This European Standard applies to those types of level indicators that are direct and indirect reading devices (e. g. sight glasses, frosting tubes), and includes electrical and pneumatic indicators. This European Standard describes the procedure to be followed when designing (by calculation or by an experimental design method) level indicator parts subjected to pressure as well as the criteria to be used for the selection of materials. This European Standard applies to the design of level indicators with respect to pressure containment and describes methods by which the reduced impact values at lower temperatures may be taken into account in a safe manner. It also gives guidance on some aspects of application and installation.

ASTM C1696-12 工业热绝缘系统标准指南

When choosing a thermal insulation product or combination of products, physical, chemical and mechanical properties and the significance of those properties should be considered. ASTM test methods are usually performed under laboratory conditions and may not accurately represent field conditions depending on process temperature, environment, and operating conditions. Performance results obtained using ASTM test methods can be used to determine compliance of materials to specifications but do not necessarily predict installed performance. Values stated in the ASTM material standards are those that apply to the majority of materials and not to any specific product; other tested values may exist for specific material applications. Design of thermal insulation systems requires the understanding of process requirements, temperature control, heat loss criteria, control of thermal shock, and mechanical forces on insulation generated by thermal gradients and wind environmental conditions. Sometimes, the mechanical design of piping and equipment needs to be modified to support insulation adequately and provide for insulation weatherproofing. Process requirements may dictate the control of critical temperature to prevent freezing, maintain viscosity, or minimize internal corrosion. When handling heat transfer fluids such as ethylene oxide or hot oils, the selection of insulation materials and the insulation system design becomes critical. whereby If these fluids are absorb in insulation materials, the fluid flash point could be below the fluid operating temperature. Specified heat gain or heat loss and acceptable surface temperatures could also dictate thermal design of insulation systems. Environmental corrosivity, high wind, and extreme ambient temperatures affect the selection of weatherproofing and methods of its securement. A combination of these factors plays a significant role in the selection of insulation materials and application methods to provide long-lasting trouble-free service. Application methods are generally defined by the purchaser's specifications. However, some specialty insulation systems, such as prefabricated insulation panels for ductwork, precipitators, and tanks, will also have supplemental installation requirements specified by the insulation system manufacturer. defined by the specification of the manufacturer. In any application of thermal insulation, the insulation requires protection of some type, be it protection from the elements such as rain, snow, sleet, wind, ultraviolet solar radiation, protection from external forces that can cause mechanical damage, vapor passage, fire, chemical attack, or any combination of these. This protection can be provided in by metal, plastic, coated or laminated composites or both, mastic coatings, or a combination of the above depending upon the application, service, and economic requirements. Considering the enormous overall cost of a new facility, and comparing the initial cost of the insulated portion as a small percentage of that overall cost with the substantially increased operating cost as a result of inefficient insulation protection, it is common sense to provide only the best insulation system available and the best protection for that long-term investment consistent with the appropriate design and economic requirements. Usually a new facility is very expensive and the initial cost of the insulation portion is a small percentage of that overall cost. However, increased operating costs can result from inefficient protection. Bid invitations should contain information necessary to determine how guarantees of materials and application will be resolved. It is recommended that the purchaser provide a quality assurance program that defines the inspection of all materials, material safety data sheets (MSDS), and specific application procedures before and during progress of the insulation work. During contrac.......

The “Allowable Stress Design” method has long been used for the design of steel structures in the United States. 13233 Recently, the probability-based Load and Resistance Factor Design (LRFD) criteria have been successfully applied to the structural design of hot-rolled steel shapes and built-up member^.^ The AIS1 LRFD Specification is being developed as well for the design of structural members cold-formed from carbon and low alloy steel^.^ The LRFD criteria offer an improved approach for the design of steel structures because they involve probabilistic considerations for uncertain variables in the design formulas.
