GPP Extreme Pressure Provides Waterjet Infrastructure

GPP offers highly engineered basic elements of any waterjet infrastructure, tubing, fittings, and valves. Ordinary plumbing systems can be successfully created with components available from hundreds of parts vendors. However, in high pressure systems, the source of componentry does make a difference. With GPP’s expertise in metallurgy, machining, and high-pressure engineering, you are assured of…

Pressure Autofrettage for Service Life Extension

The extreme water pressures used in waterjet equipment cause very large tensile (stretching) stresses at the wetted surfaces of the stainless steel high pressure parts. Repeated changes in these pressure-induced stresses from normal pump operation will eventually result in formation and growth of metal “fatigue cracks” at these same wetted surfaces, causing part failure manifested…
