Harwood Engineering Co., Inc.

Harwood Engineering offers a comprehensive range of high pressure components and testing services for superior performance and long lasting durability. Harwood tubing, valves, fittings, adapters, transducers, and safety assemblies required for industrial grade systems guarantee precision measurements and reliable standards. Harwood’s standard high pressure components have remained at the forefront of the industry since 1948. Premium materials and exacting standards are a hallmark of Harwood. Proper metallurgy, strength, finish and quality ensure long service lifespan without fatigue, while a full range of sizes and styles of standard components ensures accurate control and optimized operation.

This pressure vessel was originally developed for geologists who require pressures up to 14 kilobar and temperatures of up to 1500oC in the working cavity, using inert gas as the pressure medium. It has closures on both ends of the cylinder. The top closure carries a pressure port for 200, 000 psi. The bottom closure carries 4 lead thrus for power (allowing 3 zones for heating) and 4 thermocouple lead thrus (allowing the 3 thermocouples to separately monitor each of the zones). Pictured to the right is an example supplied with a water-jacket and trunnion mount. This internally heated pressure vessel (IHPV) may also be used as a normal pressure vessel by removing the furnace. With the furnace in place, the working cavity is ½” diameter by 2-½” long. Without the furnace, the working cavity extends to 2-½” diameter by 8-½” between closures. This vessel may be used for either gas or liquid as a general purpose test vessel. Other porting options are also available for the closures.

We recognize that many institutions or organizations looking to invest in pressure testing equipment, research and development projects have unique needs and often find themselves searching for a confident and established all-in-one supplier. Here at Harwood Engineering we offer to customized high pressure generating systems, test vessels or reaction chambers, measurement devices, and other specialized tools. Harwood is confidant that our state-of-the-art technology and dedicated team of high pressure experts can provide a customized solution for your pressure testing needs.
