Used Shell And Tube Heat Exchangers in Guangdong, China

1314151617

Overview

Shell and tube heat exchangers are heavy-duty industrial devices that transfer heat between fluids using a bundle of tubes inside a pressure shell. They handle high temperatures and pressures, offer many material and design options, and are common in petrochemical, power, HVAC, and process industries. Used units are attractive because tubes can be replaced, but require careful inspection for corrosion, tube wear, leaks, and code compliance before purchase.

FAQ

What should I check when buying a used shell and tube heat exchanger?

Check design specs (flow rates, pressure, temperature), materials of construction, ASME or PED stamping, service history, tubing condition (wall thickness, corrosion, pitting), tube-sheet condition, end covers, and past repairs or thermal damage.

How do I prepare a shell and tube exchanger for shipping?

Fully drain and flush fluids, isolate and tag connected piping, remove fragile internals if recommended, coat exposed metal with preservative, secure tube bundle, protect nozzle faces and lifting points, and arrange appropriate heavy-haul transport and crane services.

What maintenance is needed after purchase to ensure reliable operation?

Start with a detailed inspection and pressure/hydrostatic test. Implement a cleaning plan (chemical or mechanical descaling), inspect and test tubes for leaks, replace gaskets, monitor for fouling and corrosion, and follow periodic inspections based on service severity.
