It is indirectly is useful for site inspectors.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">1. GENERAL<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">1.1. SCOPE<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This Engineering Specification covers the minimum design and material requirements for steam tracing of process and utilities piping systems and equipment as shown on the P&amp;IDs, UDDs and Interconnection Drawings for process or winterization reasons for use in industrial plant.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For instrumentation, this specification covers only for in-line instrument except transmitters and local instruments such as pressure \/ level Gauges. Tracing of instrumentation shall be in accordance with Engineering Specification for Control and Instrument.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, the electric tracing and the steam tracing of piping to be supplied with the manufacturer&#8217;s proprietary or standardized equipment is not covered in this specification.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">1.2. SPECIFIC JOB REQUIREMENTS<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Specific job requirements attached here to cover modifications to this specification.
