A flowmeter shall be provided between the knock-out drum and the flare, with a straight run of at least 10 pipe diameters upstream and 5 pipe diameters downstream to ensure steady flow. 2. Steam tracing tubing must be tough enough to withstand steady heating as well as the pressure associated with steam. While these systems are fairly stable and safe when designed properly, they still require relief valves and other safety measures that can be used to address concerns such as pressure buildups . It is also necessary to be able to periodically clean the pipework to remove built-up impurities deposited on the wall of the pipe over time. Service requirements for the main pipe must also be built into the design. 查看更多2个回答 . 2人已关注
