Hairpins: Double Pipe and Multitube Heat Exchangers

Cost Effective

In many applications, performance can be achieved by a single hairpin as opposed to multiple Shell & Tube exchangers, resulting in lower capital costs, as well as future maintenance.

Cyclic or Shock Service

Large-radius U-bends and all terminal connections located at the same end allows for more extreme thermal expansion without the need for an expansion joint.

Durable Baffle Cage

Baffles are welded to tie rods without “sleeves” or internal nuts.

Extreme Terminal Temperature Differential

Independent-tube sheets and closure components eliminate differential thermal expansion across a single-tube sheet design, as is typically encountered with conventional Shell & Tube.

High Pressure

Our unique closure technology allows for pressures exceeding 10,000 psi.

Large-Radius U-Bends

Easy to clean, and eliminates the need for expansion joints or packed joints.

Moveable Support Brackets

Allow shell expansion and contraction; eliminate sliding plates; slotted on all four sides for flexible installation and future additions.

Separate Tube Sheets

Handles high temperature differences and cycling more effectively.

Small Footprint

Due to the geometry of hairpins, the equipment takes up less space relative to the Shell & Tube alternative.

Temperature Cross

Ideal when a temperature cross exists, or a close temperature approach is desired due to its single-pass configuration that allows for true countercurrent flow.
