间接式油田加热器规范（第八版

[中文适用范围]： 本规范涵盖了用于石油、天然气及其相关流体生产的油田间接式火焰加热器的设计、制造和车间测试的最低要求。它们通常位于井口和管道之间生产流线上的某个点。本规范涵盖的加热器部件包括加压线圈、外壳、加热器浴、火管和点火系统。当线圈被提供用于焊接的斜角时，加热器线圈的端接应位于第一个斜角处，或者当配件被提供为线圈的入口或出口连接时，端接于第一个配件的表面。盘管入口和出口之间的所有配件和阀门均应考虑在盘管限制内。本规范范围之外的加热器包括蒸汽和其他蒸汽发生器、再沸器、使用除水溶液以外的热介质的间接加热器、所有类型的直燃加热器、壳管束或电加热元件以及在低于低于-20°C。 [外文原描述]： This specification covers minimum requirements for the design, fabrication, and shop testing of oilfield indirect type fired heaters that are used in the production of oil, gas and associated fluid. The heaters are located at some point on the producing flowline between the wellhead and pipeline. Heater components covered by this specification include the pressurized coils, the shell, heater bath, firetube and the firing system. For purposes of this specification, the termination of a heater coil is at the first bevel when coils are furnished beveled for welding, or the face of the first fitting when fittings are furnished as the inlet or outlet connection to the coil. All fittings and valves between the inlet and outlet of the coil are to be considered within the coil limit. Heaters outside the scope of this specification include steam and other vapor generators, reboilers, indirect heaters employing heat media other than water solutions, all types of direct fired heaters, she
