There are a number of benefits with this type of element and they offer high flow rates with very low pressure drops.

Conversion Chart - Some useful conversions

Duplex Stainless Steels Duplex Stainless Steels are unlike the 300 (Austenitic) and 400 (Ferritic) series of stainless steels in that they have a structure consisting of approximately equal amounts of both ferrite and austenite. Therefore, they are often referred to as ferritic-austenitic stainless steels. With a chromium content ranging from 18 to 28 percent, they have improved passivity compared to standard grades. The nickel content ranges from 4.5 to 8 percent which is insufficient to promote a complete austenitic crystal structure, hence the mixed ferrite-austenite structure. Most grades contain molybdenum in the range of 2.5 to 4 percent plus small amounts of nitrogen – enhancing both strength and pitting resistance.

Flanges - A flange is designed to connect sections of pipe, or to join a pipe to an assembly such as a pressure vessel, valve or pump. Flanges are joined by bolting, and sealing is completed with the use of gaskets, and fixed to the piping system by welding or threading.

JIC Fittings - JIC Fittings and Adaptors provide a straightforward, positive, mechanical seal. They have been used for many years for reliable sealing in commercial, industrial and military applications. They are proven to supply dependable, reusable connections under a wide range of operating conditions including extremes of vibration, temperature and shock.

Heat Exchanger, Condensor & Boiling Tubes - Useful technical datasheet

Hygienic and Tube - Prochem is well established as a supplier to the food industry. A comprehensive range of BSM, Tri-clover and buttweld fittings and valves are available throughout Australia, complete with welded and annealed polished tubes to suit. 

Indent Service

King Instrument Company - King Instrument Company offers a comprehensive line of variable area flow metres including acrylic, polysulfone, glass and metal tube metres. Optional alarms and 4-20 mA transmitter available on selected models. See more technical information on ICEweb's Flow page.

Manual Sample Systems - Due to the growing complexity of the industrial processes in general and more specific for processes in the (petro)chemical and pharmaceutical industries, the need for tests and analyses increases continuously. The need for representative samples plays a critical role in ensuring product verification. Yet sampling directly from the process often includes the risk of exposure to the operator, as well as contamination and pollution to the environment. The Manual Sample Systems method reduces such risks with its patented design and simple method of operation.

NPT Fittings - NPT fittings are designed for high-pressure (class 3000 - class 6000) applications, and have a distinctive profile for maximum strength. All NPT products are checked with calibrated gauges during the manufacturing process and each batch is further confirmed as being in compliance with the international thread standard. Before they are released into the market, each item is subject to a final visual and dimensional inspection by thread profiling. Materials used comply with ASTM A403 or A182.

O'Brien Tracepak - The economical choice to field fabrication - Maintenance free TRACEPAK not only saves money and time during the installation process, but it ensures consistent, repeatable performance. Field fabrication requires a pipe fitter to lay out, measure, cut, dress, bend and install the tubing. Next the tracer (steam or electric) has to be installed and insulation put on the tubing. Finally, a weatherproof covering needs to be applied over the insulation. Clearly the economics of the TRACEPAK system versus field fabrication are significant.

O'Brien Analytical - TrueTube is a family of tubing products developed to provide best-of-breed performance in sample transport for process and emissions analyzers. O’Brien Analytical starts with select grade tubing and enhances its physical characteristics to improve dry-down, adsorption and corrosion resistance. This is achieved by controlling surface roughness, cleanliness, surface chemistry and reactive contaminants.

Offshore Oil and Gas Speciality Valves - Pacson Valves - These are high integrity valves specifically designed for the Oil and Gas Industry.

Offshore Oil and Gas Speciality Valves - ATC Actuators - The heart of the ATC actuator design is the revolutionary torque conversion mechanism combined with the integrated actuator spring. The simple operating principle offers a combination of high efficiency and small displacement, thereby creating greater design flexibility and improved reliability. This design flexibility, combined with the innovative integration of all actuator parts, results in the most compact actuator available in the market. In virtually all applications, irrespective of hydraulic or pneumatic supply, the ATC actuator diameter is smaller than the Face-to-Face dimension of the valve.

Specialist Valving Solutions - BSM - Hard to obtain valves need specialist engineering.  These valves are manufactured  in a wide range of exotic materials to tight specifications..
