How Does It Work?  

Internal Modulation
This unique patented design assures precise steam control and produces predictable results based on the position of the stem plug. A variable-area steam nozzle meters steam flow at the point where steam and liquid first contact and mix. This technique eliminates the need for an external steam control valve and provide efficient heating control to your process.

Choked Flow

Choked flow is the phenomenon of accelerating a vapor to maximum velocity by creating a pressure differential through an engineered nozzle. Establishing choked flow precisely controls the heating of the liquid by metering the steam flow. Because of this metered flow, your steam is used efficiently; providing effective heat control to your water.

An Overview of Sanitary Fittings

A lot goes into creating and maintaining a sanitary process, regardless of whether you are in food, beverage or pharmaceutical manufacturing.  The requirements to meet 3A, FDA and other sanitary guidelines are especially demanding.  Everything that the product touches, from pumps to tanks to piping, it is engineered to eliminate crevices that can create and harbor bacteria. Let’s tip our hat to the sanitary fitting, that is definetely one of the most useful pieces of equipment in your plant.

Sanitary Fittings 

A sanitary fitting connects different sections of your process – piping to pumps to heat exchangers and lastly to tanks.  A sanitary fitting is 2 ferrules, a gasket and a tri-clamp to hold them together. 

 A groove on the face of the ferrule provides a seat for the gasket.  The clamp provides the mechanical force to compress the gasket between the 2 ferrules.  Our hand tightens the clamp and we use torque tools to ensure a constant amount of force and eliminate over-tightening. 

 In sanitary processing, these fittings are more popular because they are easy to assemble, extremely easy to clean, leak-free and, when assembled correctly, have no small nooks or crannies to harbor bacteria.

The clamped union is the critical element for evaluating pipe pressure capacity.  Be certain your pressure ratings are for the union – not just the clamp.

Clamp Fittings 

Clamp style fittings are most popular because they offer easy assembly and breakdown of process lines and equipment.  They are available in 304 and 316L stainless steel in sizes ½” through 12”.

Weld Fittings 

Weld fittings is what we use are on permanent installations where process piping and equipment can be cleaned in place (CIP) and removal of the system components is not required.  We offer weld fittings in nominal tube sizes from ½” through 8” in both 304 and 316L stainless steel. Uniform wall thickness for ½” through 3” sizes measures 0.065.  In 4” size, wall thickness measures 0.083.  In both 6” and 8” sizes, wall thickness measures 0.109. It meets all 3A requirements. 

Bevel Seat Fittings 

We use bevel seat fittings on process equipment and piping to ensure rigidity of the system which is extremely important. Bevel seat unions consist of a threaded bevel ferrule mated with a plain bevel ferrule. We offer both in 304 or 316L stainless steel.  Bevel seat fittings meet all 3A requirements and are available in 1” through 4” sizes.

Gasket Selections

An again, 2 ferrules, a gasket and a clamp make up the tri-clamp fittings. Gasket selection is key to ensuring a leakproof connection.  The most common gasket materials are:

  • BUNA – nitrile rubber (NBR); a copolymer of butadiene and acrylonitrile
  • EPDM – ethylene propylene diene rubber
  • FPM – flourinated propylene monomer, commonly sold under the trade name Viton®
  • PTFE – polytetrafluoroethylene elastomer, commonly sold under the trade name Teflon®

For additional information on gaskets, check out our Elastomer Compability Guide and our Basic Elastomer Characteristics Guide.

Before tightening the clamp, make sure the gasket is seated properly into the seats of both ferrules.  Misalignment of the gasket is one of the main causes of leaks in tri-clamp fittings.

Solving Separation Anxiety with Systems Controls

One would expect a systems control integrator to understand equipment controls.  But what happens when your controls integrator also understands the process?

You get an improved production process, reduced maintenance, and more productivity!

Separator with Systems Controls 

A beverage producer in SC uses a separator as part of a hot tea fill process.  The original separator program forced the bowl to spin down when flow was not detected after several minutes.  The customer deemed that the time to spin down and then speed back up to processing speed was too long. He was losing too much production time.

The original integrator who installed the hot fill line changed the separator controls which allowed the separator to spin. Even when tea was not flowing, the separator would spin.  Because of the continuous spin of the bowl it created excessive heat, leading to a breakdown of the bowl gaskets. The gasket wear created a flow path around the seals to the solids discharge port on the separator.     

The customer then contacted M.G. Newell for help.  Our Newell Automation engineer installed a flow switch and timer on the outlet of the pump feeding the separator and then added a water circuit that allowed water to flow through the separator and to the drain.  He also programmed the system to allow automated butterfly valves to open when tea flow was not detected for the timer set point.  The water would flow to the separator inlet, through the separator and then dump to drain until the flow requirement was met.

After three months, the life of the bowl gaskets has increased 4-fold. The plant no longer has unplanned downtime due to gasket failure.  This has resulted in increased productivity and reduced maintenance costs.

Our Newell Automation team has a goal to understand the purpose behind the process.  They work with our process engineers to troubleshoot and streamline the process.  Contact one of our associates today to see how We Make It Work Better.

Carlton Scale

Attached pipes are the crucial difference between tank scales and other industrial scales such as platforms. As a tank scale is loaded, it deflects downwards pulling with it the attached pipes which apply an increasing upward force. This reduces the amount of weight registered by the load cells effectively reducing the sensitivity of the scale. Metrology can be seriously impacted if the scale is not designed and calibrated correctly.

Ideally, calibration is done by applying test weights which exercise the scale support-structure and piping, thus simulating normal scale operation exactly.

This exposes the piping effect on scale sensitivity allowing it to be accounted for in the calibration process, something that cannot be achieved with any form of electrical or theoretical calibration. However, test-weight calibration can be difficult and time-consuming. Additionally, test weights are expensive and may not be available, especially for higher-capacity scales.

One to four RapidCal modules can be used, depending on the scale arrangement. They attach between anchor points on the scale and on the foundation directly below, using special hardware and threaded rod to adjust length. A hand-operated pump causes the hydraulic cylinders to retract, thus applying the downward force to the tank via the reference load cells. These load cells are connected to a separate terminal which monitors the process and provides the total load applied for calibration and/or adjustment.

The RapidCal method uses tension hydraulic cylinders to create the downward force that is measured by reference load cells. The equipment is modular; one to four calibration modules can be used depending on tank design and capacity. 

There are three main steps during design and installation: 

1. Select the number and capacity of the RapidCal modules to be used. 

2. Select the type and placement of T-anchor points on the tank.  

3. Select the type and placement of B-anchor points on the floor/base.

Magnetic Flowmeters 101

Flowmeters 101 

Magnetic Flowmeters – How They Work 

Flowmeters play a vital role in sanitary processing.  They are used to measure incoming raw materials, incoming water supply, CIP solutions, ingredients in your formulation, final product production and even waste water leaving the plant.  Considering their use in critical applications, ensuring that you are using the right type of meter with the correct level of accuracy for your application can be the difference in the quality of your product and save you thousands of dollars in lost revenue or profit.

Magnetic Flowmeters

Magnetic flowmeters (or mag meters) use Faraday’s Law of Electromagnetic Induction to determine the flow of liquid through a pipe.  This type of flowmeter works by generating a magnetic field and channeling that through the liquid in the pipe.  Faraday’s Law states that flow of a conductive liquid through the magnetic field can cause a voltage signal that electrodes are sensing on the tube walls.   When the fluid is moving faster, more voltage is generating.  The voltage generated is proportional to the movement of the liquid.  Transmitters process the voltage signal to determine liquid flow.
The signals produced by the voltage are linear with the flow.  With this, the turndown ratio is very good without sacrificing accuracy.

Pros and Cons

Since these flowmeters measure conductivity, obviously the fluids measured need to be conductive – water, acids and bases.   Low conductive liquids, such as deionized water or gases, can cause the flowmeter to turn off and/or measure zero flow.  There is no obstruction in the path of the liquid, therefore no induced pressure drop across the meter.  One other benefit of mag meters is that they are able to use gravity-fed liquids.  With gravity-fed liquids, the flowmeter orientation is vertical so that the flowmeter is completely filled with liquid.  These flow meters are sensitive to air bubbles because the meter cannot distinguish entrapped air from the liquid.  Air bubbles will cause the meter to read high.

We choose mag meters because they have no obstructions, are cost-effective and provide highly accurate volumetric flow.  Additionally, they can handle flow in either direction and are effective at low and high volume rates.

Electropolishing vs. Passivation

Electropolishing vs. Passivation

Addressing Common Misconceptions 

One of the most frequently asked questions online, “Which is better, passivation or electropolishing?” is driven by a misunderstanding of the two processes and the different roles they play. In fact, the two processes are frequently complementary and doing one without the other can result in an unreliable system requiring constant maintenance.

For some applications, treating stainless steel with both electropolishing and passivation may be necessary to maximize the metal’s resistance to corrosion and meet specific standards. Two major industry standards with stringent surface chemistry requirements that may necessitate both treatments are: SEMI (Semiconductor Equipment and Materials International) standard, which is widely used in the semiconductor and electronics manufacturing industries.

What is Electropolishing? Superior Finish and Performance

What is Passivation? Enhancing Corrosion Resistance

Identifying and Addressing Contamination or Corrosion

Electropolishing utilizes a combination of electricity and chemistry to smooth the metal’s surface by removing the metal from the peaks of any raised surfaces on a microscopic level.

The metal removal rate is controlled by the electrical settings of the electropolishing equipment, the process is repeatable for a given alloy, electrolyte concentration and conductivity, and current density combination.

A well-electropolished surface significantly reduces locations where contamination can become caught on the surface and become a point where corrosion will flourish.

Passivation, on the other hand, is a chemical treatment to enhance stainless steel’s natural passive layer which protects the underlying metal from corrosion.

The passivation chemistry removes free iron or other metallic impurities on the surface which would become a source of corrosion.

The result is a contaminant-free, chromium-rich oxide layer that is chemically inactive, or “passive.”

Early warning signs of contamination or corrosion are typically found during the regular quality control sampling and inspection of a system and, depending on the situation, can be addressed by remediation, cleaning and a passivation treatment.

However, in situations where the symptoms are missed, or not addressed, both metallic and biologic surface contamination can result in accelerated corrosion through the underlying metal. In the most serious cases, the part fails and will have to be replaced. It goes without saying that any product that has passed through this system risks being seriously compromised.

Even if the situation is caught before failure, the pitting that occurs due to corrosion will need to be repaired. This will involve mechanical polishing, followed by electropolishing and then passivation of the affected area to bring it up to the same level of protection and cleanliness as the rest of the system.

Routine Maintenance and Preventative Measures

In most cases, electropolishing will need to be performed only once and then passivated as part of commissioning a system. The result is a smooth surface, meeting the surface roughness requirement of the system, presenting fewer opportunities for internal corrosion or contamination to spread through the system to other locations, or into the product itself.

By including passivation as part of a maintenance plan, plant owners can be proactive in preventing corrosion or other contamination buildup. This decreases the likelihood of
unscheduled remediation services and aids in the longevity of the system itself.
