Davit arms turn bundle removal from a crane operation into a routine task, and they cost far less specified with the unit than retrofitted. Saddle supports, lifting lugs and sliding-saddle slot details are all sized against calculated thermal growth.
On vertical units the equivalent items are lug or skirt supports and a confirmed overhead lift route.
Where the bundle will be pulled on a schedule, a spare bundle ordered with the exchanger is the shortest path back into service: the plant swaps bundles in an afternoon and cleans the fouled one off-line. Bundle pullers and extraction rails are sized to the bundle weight and the clearance in front of the shell, and that clearance is confirmed on the layout drawing before the unit ships.
Process and Safety Fittings
Vacuum breakers where a steam space can go subatmospheric on cooldown. Sight glasses where liquid level or flow needs to be seen. Vents and drains located at the true high and low points in the installed orientation rather than where the drawing found convenient.
On sanitary units, spray balls, annular distributors and sanitary sample connections are specified alongside the exchanger so that dead-leg limits are respected.
Relief valves are sized to the shell and tube side design pressures, and a tube-side relief is specified wherever a blocked-in cold fluid can be heated by the shell. Pressure gauges and temperature gauges at the four nozzles are inexpensive and are the first thing a technician needs when performance is questioned.
Questions About Your Duty?
Call and talk it through with an engineer: 1-805-484-2992, 8am to 5pm, or send the duty through the quote form on this page.
Insulation and Instrumentation
Removable insulation jackets for personnel protection and heat conservation, designed so the bundle can still be pulled. Thermowells and pressure connections sized and located for the control scheme rather than added afterward.
Tell us the accessory list at quotation. Every one of these works better as part of the drawing than as a field modification.
Flow switches or differential pressure transmitters across the tube side give early warning of fouling, and a sacrificial anode in the channel protects copper-alloy tubes where the cooling water is aggressive. Each of these is listed on the quotation as a line item, so it can be accepted or deleted without changing the exchanger itself.
