With the known temperatures on each end of the coil, the heat duty for each coil can be calculated from the heat transfer theory. Since the bath is at a constant temperature, LMTD can be calculated as:


The overall film coefficient, U, for the coil can be calculated or read from the charts and tables in [...]]]></description>

Before choosing a wall thickness it is necessary to choose a pressure rating for the coil. Typically, the high-pressure coil (L1) is rated for the shut-in pressure of the well, and the low-pressure coil (L2) is rated for the maximum working pressure of the downstream equipment. There are many exceptions to this rule and reasons [...]]]></description>

Erosional flow criteria will almost always govern in choosing the diameter. Sometimes it is necessary to
check for pressure drop in the coil. Typically, pressure drop will not be important since the whole purpose of the line heater is to allow a large pressure drop that must be taken. The allowable erosional velocity is given by:

		<description><![CDATA[In order to choose the coil length and diameter, a temperature must first be chosen upstream of the choke; the higher Th the longer the coil L] and the shorter the coil L2. In Heat Transfer Theory we showed that the greater the LMTD between the gas and the bath temperature, the greater the heat [...]]]></description>
