    C is more resistant to corrosion than Hastelloy C, and this is one of the reasons why many people prefer C over C The cost of the material as well as the lifespan of the material will depend on how well it can withstand different environments. There are quite a few differences in the chemical compositions of C and C There are no hardness or environmental limits on the use of Hastelloy C4 (CW-2M) in NACE MR When H2S is present the pump is required to pump both gas and liquid. In many pumps this will cause cavitation and subsequent pitting. Our rotary lobe pumps are well suited for pumping liquid containing under PPM of H2S gas.

    Some of my most interesting and gratifying projects I ever worked on were high-production geothermal pump and re-inject projects. The concept fell into my lap while working on a contract with the school district in Cedar Rapids, Iowa—and after discussion with lawyers, department of natural resources personnel, nearby residents, and others, it.

    These are Pete Port Needle & pressure gauge test & fill tools from SRS and are used to check pressure and or refill/charge the fluid on geothermal loops and ground source heat-pump systems. We offer the tools in 3 different configurations, and each configuration is available with either a 1/16" or 1/8" port needle. On either size, the port needles are /8" long from the face of the brass.

[G E Tardiff; E O Snell; United States. Department of Energy.; Lawrence Livermore Laboratory.]. This paper presents the results of a failure investigation carried out on a cast Hastelloy C pump impeller that suffered general corrosion in 32% hydrochloric acid at ambient temperature in a chemical plant.

Microscopic examination revealed that the attack was crystallographic in by: 4. Based on the corrosion rate measurements carried out by Corbett and Morrison, Crook and Caruso, and Gossett, Hastelloy C does not appear to be suitable for an application as a pump impeller in 32% HCl.

Furthermore, the hot summer temperature of Kuwait, which could reach 48 °C, will enhance the corrosion by: 4. Failure of Hastelloy C pump impeller in hydrochloric acid Article in Engineering Failure Analysis 15(5) July with Reads How we measure 'reads'.

To compare the performance of HASTELLOY® C alloy with that of other materials, it is useful to plot the mm/y lines. In the following graphs, the lines for C alloy are compared with those of two popular, austenitic stainless steels (L and SMO), and a lower-molybdenum nickel alloy (), in hydrochloric and sulfuric acids.

The most critical part of the pump for geothermal applications are usually the bowl/shaft bearings which are commonly made of bronze, rubber, or Teflon (PTFE).

With most low temperature groundwater source systems with groundwater temperatures under 85°F, the design of a geothermal water supply pumping system is close to a regular water system.

Hastelloy C, UNS N oris the most universally corrosion-resistant nickel alloy. It is widely used in various applications involving sulfuric acid of an extensive range of concentrations and temperatures.

The two isocorrosion diagrams shown below illustrate relative corrosion resistance of Hastelloy C material to. Hastelloy C alloy can be forged, hot-upset and impact extruded.

Although the alloy tends to work-harden, you can have it successfully spun, deep-drawn, press formed or punched. All of the common methods of welding can be used, although the oxyacetylene and submerged arc processes are not recommended when the fabricated item is for use in.

Nickel Alloy C/Hastelloy ® C Bar UNS N Nickel Alloy C and Hastelloy ® C, commonly known as UNS N, is generally considered the most versatile corrosion resistant alloy available, comprised of nickel, molybdenum, chromium, iron and tungsten. These elements combined results outstanding corrosion resistant properties particularly crevice and pitting, allowing for its.

Description. Hastelloy C is a nickel-molybdenum-chromium-tungsten alloy with excellent general corrosion resistance and good fabricability. The alloy should be considered for use in environments where resistance to hot contaminated mineral acids, organic and inorganic chloride-contaminated media, chlorine, formic and acetic acids, acetic, acetic anhydride, sea water and brine solutions is.

What is Hastelloy Steel. Many nickel-based steel alloys exhibit high resistance to corrosion, and Hastelloy is one of the best. In addition to outstanding resistance to all manner of pitting and cracking, parts made from Hastelloy metal blends tend to find good use across a wide range of chemical applications that might otherwise oxidize the metal.

Hastelloy Springs Description: Hastelloy spring material is a nickel-chrome-moly alloy with good corrosion resistance. Some grades add copper or tungsten for further enhancement of chemical resistance and pitting.Hastelloy C Bleaching Vessels w/Two (2) C U-Tube Bundles The B-3 alloy possesses outstanding resistance to non-oxidizing acids, such as hydrochloric acid and sulfuric acid.

The advantages of B-3 alloy over previous B-family alloys are enhanced thermal stability and improved fabrication characteristics.Features: Hastelloy C has excellent resistance to localized corrosion, stress corrosion cracking, and to both oxidizing and reducing media, thus making it suitable for a wide variety of chemical process environments, including ferric and cupric chlorides, hot contaminated media (organic and inorganic), formic and acetic acids, seawater and brine solutions.
