Gas, liquid, steam, and two-phase duties do not necessarily require identical data.<\/p>\n<p>Pulsation information should also be conditional. If pressure dynamics are material, a note saying <em>pulsating service<\/em> may be insufficient; available operating-case data or pressure traces can provide a clearer engineering basis. If pulsation is not material, there is no value in adding a complex dynamic-analysis requirement merely to make the RFQ look more complete.<\/p>\n<p>Operating temperature and relieving temperature should be distinguished where they differ. Likewise, <code>Back Pressure: Yes<\/code> should be replaced with the downstream condition that actually needs review.<\/p>\n<p>The supplier response should explain <strong>why the proposed candidate fits the defined duty<\/strong>, not just provide a model number.
