Safety
Every Quintus Technologies HIP features a vessel and yoke frame that are fully pre-stressed and wire-wound with high tensile cold-rolled spring steel ribbon. The pre-stressing causes the pressure vessel wall to remain in residual compression, even at maximum operating pressure, eliminating tensile loads and preventing crack propagation and brittle failure.
It is widely acknowledged to be the safest, most reliable and durable pressure containment system ever designed. The vessel meets “leak-rather-than-burst” criteria as defined in the ASME code, and typically has a calculated fatigue life of more than 20,000 cycles. Because the load-absorbing wire ribbons in the Quintus Technologies design have a tensile strength twice that of a forging, the system is lightweight and compact, with a savings in weight up to 50% compared to non wire-wound forged vessels.
Productivity
Quintus Technologies’ URC® and URQ® quench furnaces can provide decreased cycle time, higher productivity, and even combined HIP and heat treating. They can easily cool the full workload in a medium-sized HIP from 1,260 to 300°C in less than 30 minutes.

In an equivalent HIP system, natural cooling can take from 8 to 12 hours, well over half the typical cycle duration. Our URC® design cools all areas of the workload uniformly, minimizing thermal distortion and non-uniform grain growth.
