SW Impreglon Will Be Exhibiting at Turbomachinery and Pump Symposia

Southwest Impreglon will be exhibiting at the 43nd Turbomachinery and 30th Pump Symposia September 23-25 in the George R Brown Convention Center, Houston TX booth 2017. 

Southwest Impreglon will be highlighting several coating technologies for turbines, reciprocating equipment, and pumps.   In particular, Impreglon 809 , Impreglon 807 Blue, Xylan®, Impreglon 445  and polyurethane coatings will be featured.

Southwest Impreglon applies proprietary Impreglon 809 aluminum-ceramic thin film coatings aluminum to provide long lasting corrosion resistance to metals operating in harsh environments up to 1200oF.  The coating system cuts costs by reducing downtime, extending service life, and slowing part wear.  This coating is especially good for extending the service life and operating efficiency of turbine blades and vanes.  Southwest Impreglon also applies Praxair SermaGard® and Alseal aluminum-ceramic coatings.

Impreglon 807 Blue is a multi-layer systems consisting of  an aluminum rich base coat, epoxy/phenolic mid-coats, and fluoropolymer top coats.  The coating provides a hard, abrasion resistant, corrosion, and chemical resistant, non-stick film that offers excellent performance up to 400oF.

Xylan® are fluoropolymer-based coatings that are formulated to prevent galling, provide lubricity, improve corrosion resistance, as well providing different colors.   Southwest Impreglon applies  numerous Xylan® coating as dry-film lubricant; however they also have many desirable secondary properties.  Xylan coatings can work under heavy loads, up to 500oF, in corrosive chemical environments, and combinations thereof.

Impreglon 445 is an epoxy coating designed to corrosive environments in the oil and gas industry.  Typical applications include sucker rods, valves, pumps, and brine water treatment and handling equipment.

Polyurethane coating are exceptional for abrasion resistance and impact resistance.  Polyurethane are often coated into pump internals to reduce the damage due to cavitation and abrasion due to pumping slurries.  Polyurethanes coatings provide a seamless alternative to rubber linings often with better service life.

Southwest Impreglon applies functional coatings for oil and gas, power generation, and chemical industries.  We apply over 300 coating systems including Xylan, Teflon, Sermagard, TSA, and Halar.  Company was founded in 1975, operates on 12 acres, and processes parts within 80,000 square feet of manufacturing space in Humble TX.

Southwest Impreglon, Inc. has increased it’s production capacities for Thermal Spray Aluminum (TSA) coatings. These sacrificial coatings provide much better corrosion resistance than paints and galvanizing. The advantages of TSA include: long term durability and protection even with a porous or breached coating, and the ability to quickly coat large parts.
Southwest Impreglon uses the “twin wire arc” method which sprays atomized molten aluminum onto a metal substrate to produce coatings which are typically 0.006” to 0.010” thick. This method offers exceptional coating bond strength.

In addition to sub-sea and marine applications, TSA is often used for corrosion protection in petrochemical plants as a solution to “corrosion under insulation” (CUI) attack. These aluminum coatings offer protection for aggressive environments containing oxygen and sulfur. These corrosive effects are enhanced for processes operating at high temperatures, leading to a faster degradation of mechanical components. TSA coatings can be used up to 1000oF.

Applications in Oil & Gas and Petrochemical Industries are:

Flare stacks
Subsea trees
Suction piles
Choke and kill lines

Contact your Southwest Impreglon, Inc. representative for more information about TSA coatings and our capabilities.

Southwest Impreglon Expands its line of VICTREX PEEK Coatings

Southwest Impreglon Expands its line of VICTREX PEEK Coatings

Southwest Impreglon has expanded its line of VICTREX PEEK-based coating systems to include thin-film dispersion formulations. Previously, VICTREX PEEK, a semi-crystalline thermoplastic and member of the polyaryletherketone (PAEK) family, was only available for application as a thick film layer of (15-25) mils.

peek-polymer-coatingsVICTREX PEEK-based coatings are durable, impact resistant and pin-hole free with outstanding chemical resistance with a continuous operating temperature of (500F(260C), UL746). The new dispersion formulations now allow for VICTREX PEEK polymer to be applied in thinner coating layers of (1.0-1.5) mils thick, while lending themselves for application on more complex metal parts with closer dimensional tolerance.

When asked how these coatings compare to fluoropolymer coatings of similar film thickness, George Butler, principal and chemist for Impreglon said “All end-use applications are different, but VICTREX PEEK polymer’s excellent fatigue resistance and general mechanical properties have been shown to outperform fluoropolymers, while the chemical resistance is vastly superior to metal components for such applications. And since we are able to formulate VICTREX PEEK with other polymers and additives, we can further improve or incorporate certain desired characteristics for our customer’s end-use applications. We have at least seven specially formulated blends that we are currently applying and the number continues to grow as we find new applications and develop new formulations to meet our customer’s needs.”

VICTREX PEEK-based coating systems currently being applied by Southwest Impreglon are shown in the chart above.

According to George Butler, President & Co-Principal, “The originall coating facility was always built with expansion in mind to better serve the company’s ever expanding customer base as well as its continual addition of new coating processes. Now that the expansion has been completed, we invite our customers to challenge us with some of their larger parts requiring coatings application.”

Southwest Impreglon Achieves ISO 9001:2000

Southwest Impreglon Achieves ISO 9001:2000

As of August 12, 2003, Southwest Impreglon became ISO 9001:2000 Certified. This has now replaced the obsolete ISO 9002 standard to which the company had been previously been certified.

ISO-9001-2000In speaking with Terry Bourdon-Quality Assurance Manager for Southwest Impreglon, he said meeting the criteria for the new standards was tough, but well worth the time it took to get there. Achieving certification required hours of close review and usually, revisions in the company’s quality manual, procedures, work instructions and other forms.

Asked why ISO certification was so important, he responded that “Certification was important to us because it is recognized worldwide as an accepted standard of quality. When companies can accurately document their quality systems, they can compare their systems against a recognized quality standard and improve what they offer to their customers. Also, because ISO certification is an understood standard, companies can use it to gauge and select the vendors or sub contractors they work with. Having successfully gone through the ISO review process and achieved ISO 9001:2000 certification, customers can trust that Southwest Impreglon has already asked the tough questions about its own quality systems”

Impreglon Coating Technologies Yield Breakthrough Performance in the search for Energy

Impreglon Coating Technologies Yield Breakthrough Performance in the search for Energy

As our quest for petroleum-based energy takes us deeper and deeper beneath the Earth’s crust, the technologies employed not only become more specialized, but the cost of drilling for these precious resources becomes a high-stakes enterprise few can afford to lose. Consequently, even small increases in productivity can have a big impact on the bottom line. This is especially apparent when considering the cost of drilling a moderate-sized well can easily run more than $250,000 a day, with completion times measured in weeks or even months.

oil-drillingThis is the challenge presented to engineers at Southwest Impreglon: Discover a new coating that allows ultra-sticky shale particles to release downhole and transport out via the water-based drilling fluid.

“We see challenges similar to this on a regular basis,” said Impreglon president and chief chemist, George Butler. “What we bring to bear is a team that understands how to analyze a technical problem and apply the full spectrum of available technologies to a solution – or in many cases, create new solutions.”

The problem was shale would bond so tightly to downhole equipment, drilling and mud circulation became impossible. In fact, they needed hammers and chisels to free equipment retrieved from these dense, gummy formulations.

Working in partnership with an international oil tool manufacturer, Impreglon began testing a variety of coatings, application processes and curing methods. It quickly became apparent that the oldest, and perhaps best known coating, was the most effective. “Sometimes, solutions are staring you right in the face, you need the expertise to see and apply them,” said Mr. Butler. In this case an existing technology had almost ideal characteristics, but required some innovative modification of the binding approach to match the unique demands downhole.

Coating downhole tools with Polytetrafluoroethelyne (PTFE) wasn’t a new idea. But throughout three years of testing, PTFE proved to be the most effective coating for releasing the cement like cuttings. The problem was PTFE’s relatively weak abrasion resistance and wear characteristics were more than a small problem under these extreme conditions. After hundreds of test combinations, scores of modified application processes and countless hours under laboratory and field conditions, the right formulation of abrasion resistance and PTFE’s fast release characteristics finally came together. When all the data was compared, Impreglon and downhole tool engineers were seeing performance rate increases up to fifty percent. A significant enough increase to begin patenting the process.

Due to greatly improved application techniques and a better understanding of molecular bonding at the substrate level, new coating formulations and new patents are today not nearly as rare as they were only a few years ago.

The team of petroleum and coating engineers saw superior lubricity, greater release characteristics, lower friction and excellent corrosion resistance. The results showed longer equipment life, less downtime, higher production and reduced maintenance. Impreglon’s chief chemist asserts that this isn’t an isolated case. According to Mr. Butler, coating engineers’ experience in many different fields gives them the edge in recognizing, applying, refining and proving very specific, fit-to-task solutions that are fine-tuned to many industry’s unique demands.

As with any design element, the greatest chance of success with coatings rests with design integration’s at the earliest phase. Good coating engineers can bring a wealth of process knowledge and application expertise to project designs. Coating engineers can also adapt preparation processes to any given alloy. Depending on the substrate, specific etching, treating and texturing are prerequisites to any application.

In the final analysis, the new generation of coatings provides design engineers another set of tools with which they can modify the nature of any given metal surface to fit the demands of virtually any conditions. Because, if that coating doesn’t already exist, chances are it can be formulated.

Impreglon Undergoing Expansion

Impreglon Undergoing Expansion

Southwest Impreglon is currently undergoing a construction project to expand its custom coating facility. According to George Butler, President and Co-Principal of Impreglon, the expansion is necessary in order to better serve its current and future customer base. The original coating facility was always built with expansion in mind. However, now with the addition of even more coating processes and services to its already more than 200 offerings, the company simply ran out of room.

impreglon-expansionThe anticipated completion date for new construction is October 2002 and to become fully operational sometime in April 2003. The new construction will increase the production processing area by an additional 12,000 sq. feet and will increase the large part handling and weight capacity to 10-tons. Also included in the new construction will be the addition of a larger curing furnace to facilitate the processing of the larger and heavier parts. The inside dimensions of the furnace will be 12? x 12? x 40? long and will have an 850 degree F heating capability. Also added will be larger spray booths and blast rooms appropriately sized for the processing of the larger parts.
