Fluid Flow Imagery

In keeping with our corporate mandate and vision of "Change is Good" - we are always looking for a "better mousetrap"! We strive to continually improve within all facets of our business to provide you the ultimate in state-of-the-art products, quality and customer service.

We have recently updated our methodology of determining pressure drop calculations for our custom engineered design projects. It enables us to model flow through strainers and valves to accurately determine the pressure drop for any fluid travelling through stainless perf or mesh, to any design condition.

With this new Computational Fluid Dynamics software we are able to run comprehensive fluid flow and heat transfer simulations through our products, providing us with invaluable data on any number of technical aspects, from pressure drop to velocity magnitude, as is shown below.

Another great program tool we have acquired in the recent past gives us the capability to create "3D" computerized product models. This allows our Sure Flow Engineering Department to provide a better illustration of the installation, flow and positioning of our custom engineered products. Take a look at our new online "3D Corner" accessible at which features a variety of 3D product model videos!

Sure Flow Equipment Inc. is IS0 9001 :2000 Certified and holds an IS0 9001 :2000 Certificate of Registration from the Global Certification Network, and all products are designed and manufactured to ASME Section VIII, Div 1, Current Edition with U and UM Code Stamp available.

New Products - Butterfly Valve Seat Designs

VITON® (Fluorocarbon Rubber, abv. EPDM)
Viton® is more expensive than EPDM so is used as an alternate elastomer when required. It has excellent resistance to mineral acids, oils and many aliphatic and aromatic hydrocarbons. Viton® is weak on sodium hydroxide.
Useful temperature range: 0°F to 350°F

TEFLON PTFE (Polytetrafluoroethylene)
PTFE is almost totally insoluable and chemically inert. It has high temperature resistance. Teflon PTFE ball seats, because of natural lubricity, require no lubrication. Teflon PTFE diaphragms and flange gaskets are used in the most severe chemical resistance applications.
Useful temperature range: 0°F to 250°F

Sure Flow PMI Analyzer

Sure Flow PMI Analyzer As part of our continuous quality improvement and to allow us to have complete traceability of all materials, Sure Flow has added the usage of a PMI, or Positive Material Identification (PMI), hand held alloy analyzer to validate raw materials. Our new test equipment allows Sure Flow to perform shop floor tests to ensure materials provided to us for fabrication meet the material specifications and avoids the necessity of additional inspection by our customers. This is just one more example of Sure Flow Equipment’s commitment to providing quality products.
