Hot Isostatic Presses

Avure: your low-risk provider Customers rely on Avure Technologies for the superior engineering that results in highly reliable HIP systems that operate around the clock with service lives of tens of thousands of cycles. Using modularized sub-systems and furnaces with a wide variety of options, we work closely with you to identify specific needs and design a press that meets all your performance requirements. We have project management down to a fine art, and take pride in delivering your HIP system to spec, on time and at the quoted cost, as we have done with more than 1,000 isostatic presses in our installed base.

Unmatched durabilityMore than 90% of Avure HIPs installed over the last 40 years are still in operation. Our exclusive QUINTUS® pre-stressed wire wound vessel and frame concept is the safest, most durable and lowest weight pressure contain-ment system ever designed. And our HIP furnaces, properly operated and maintained, will last for a decade or more of intense use.

It all adds up to the lowest total cost of own-ership offered by any HIP manufacturer. Why else would the world’s leading user of HIP presses buy almost all their production HIP systems from Avure?

First in technical innovationsFor more than 50 years, Avure and its pred-ecessor companies ASEA and ABB have led the industry in advancing HIP technology: • The first systems to successfully produce man-made industrial diamonds • The first fully pre-stressed wire-wound pressure containment system • The first Uniform Rapid Cooling furnaces for dramatically reduced cycle times and HIP heat treatment • Proprietary software and internal sensors for precise, highly repeatable processing • The largest, most cost-efficient HIP systems ever built

Little wonder that, year after year, Avure leads the industry by far in the number of HIP systems sold and installed.

What ourcustomerssay:

Hot Isostatic Pressing: a proven process for high-performance partsFor decades, Hot Isostatic Pressing (HIP) has been used successfully by manu-facturers around the world to form and densify containerized powder shapes and containerless metal, ceramic and plastic parts. With typical pressures from 1,035 to 3,100 bar (15,000 to 45,000 psi) and temperatures up to 2,200°C (3,990°F), HIP can achieve 100% of maximum theoretical density and improve the ductility and fatigue resistance of critical, high-performance materials. HIPped components are often of net shape or near net shape configuration.

Common applications include:• Defect healing of castings • Consolidation of powder metal and ceramic parts• Diffusion bonding

Today, HIP is expanding into new applications such as: • Very large castings• Very large HIP clad P/M to solid or P/M to P/M wear components• Metal injection molded parts.• Large P/M parts to replace extended-delivery forgings.

QUINTUS® wire-wound and pre-stressed designEvery Avure HIP features a vessel and yoke frame that are fully pre-stessed 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 maxi-mum operating pressure, eliminating tensile loads and preventing crack propaga-tion 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-break” 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 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.

HIP furnacesIf the pressure vessel is the backbone of a HIP system, then the furnace is the heart. Avure has led the development of HIP furnace technology for decades, and today offers a wide range of advanced furnace designs featuring a variety of styles, excellent temperature uniformity and advanced temperature measure-ment techniques. Properly operated and maintained, an Avure furnace will perform flawlessly for more than 10 years of continuous, demanding service. Hot zone materials include steel, molybdenum, graphite and various hybrid combinations. Operating temperatures from 500 to 2,200°C (900-3,990°F) are available.

Uniform Rapid Cooling (URC)

Avure’s optional URC and quench furnaces can provide decreased cycle time, higher productivity, and even combined HIP and heat treating. It can easily cool the full workload in a medium-sized HIP from 1,260 to 300°C (2,300 to 570°F) in less than 30 minutes. In an equivalent conventional HIP system, natural cooling can take from 8 to 12 hours, well over half the typical cycle duration.

The quench furnace is equipped with a forced convection system which circulates cooler gas thoughout the work zone, and transfers the stored thermal energy out of the system through a combination of gas-to-gas and gas-to-water heat exchang-ers. This cuts total cycle time by more than 50 percent. Avure’s URC designs cool all areas of the workload uniformly, minimizing thermal distortion and non-uniform grain growth.

Broad product selection High-volume production systems. Avure offers large-capacity HIP presses that dramati-cally reduce per-unit processing costs, and is leading the development of “Mega HIPs” for even greater cost efficiency. The world’s largest press has a hot zone diameter of more than 2 m (79”), and the tech-nology exists to deliver HIPs with vessel diameters up to 3 m (118”). These giant capacities allow densi-fication of ever-larger products and batches, cutting costs and helping customers to grow their competi-tive advantage.

Mid-range/pilot plant models. Avure Mini-HIPpers® are smaller versions of our production presses, with standard vessel diam-eters of 203 and 252 mm (8 and 10”) and heights of 500 to 762 mm (19.6 to 30”). These presses are economically suited for lower volume products such as advanced ceramic wear parts, diamond cutting tools, sputtering targets and other small-batch applications.

Laboratory HIPs. These compact Mini-HIPpers® are designed for HIP research and feasibility studies. The pressure vessel, frame, electrohydraulic pump and all other sub-systems are housed in a single, space-saving cabinet. Work zone diameters range from 75 to 203 mm (3 to 8”), with heights from 125 to 305 mm (5 to 12”).

Quality and safetyAll Avure processes and procedures are conducted under a fully documented ISO-9001:2000 certified quality management program. Every press is designed and built to meet international quality and safety standards.

In the U.S., vessels and other high-pressure sub-systems can be code stamped to certify compliance with ASME, Section VIII, Division 3, and other applicable components meet UL requirements. For the European Community, the HIP system is CE marked and complies with the Pressure Equipment Directive (PED) and other applicable EU directives.

Avure also holds a certificate for the supply of pressure vessels to The People’s Republic of China. We have extensive interaction with other industry standards and safety regulations, and will design a HIP to meet all applicable requirements.

Worldwide service and supportAvure HIP systems are supported by a worldwide network of trained service technicians, sales engineers, and spares coordinators. Pre-sale support includes process analysis, feasibility studies, and ROI evaluations. Training courses based on comprehensive manuals covering equipment and processes, and test pressings at Avure’s Research Laboratory are available.

Ongoing service programs are offered, including inspection, preventive mainte-nance, process audits, and remote diagnostics. Uptime is everything so you can count on Avure for fast response to your service and repair needs.
