History of L-K Industries

Pursuit of the American Dream 

During the month of July, while we celebrate American Independence Day, we take pride that we offer a full catalog of products that are made in America. We welcome you to join us as we look at our history, a true example of  the American Dream.

In 1930, while the world economy was in the middle of the The Great Depression, Louis Hill Kennon founded L-K Pump & Valve Company in Houston, Texas on the beliefs that quality products and services are the pillars to building long-term success. Nearly 90 years later, L-K Industries continues operating on the same principles and is proud to carry such a well-respected name in the industry. We at L-K are proud that our products are still made at the headquarters in Houston, TX.

L-K has always searched for new ways to expand and provide value to its customers and in 1951, Louis Kennon and Sam Melton designed the first oil testing centrifuge, the “Melton Heated Oil Centrifuge.” In the mid 1950’s L-K moved to the facility in Houston where we currently reside and was renamed to L-K Industries, Inc. In 1962 the ASTM standards for testing crude through centrifugation were released based on the Melton Centrifuge and in 1963 the API standard was released for centrifuge testing.

In 1989, L-K Industries continued to expand its products by adding an in-house glassblowing shop to create centrifuge tubes. L-K’s next innovation was the first transport centrifuge model, enabling crude oil haulers to test crude quality before picking up a load. Our transport models continue to be one of our most popular products to this day.

In 1999, L-K designed its first laboratory centrifuge, the Benchmark 2000 and then in 2014 released it’s second lab centrifuge the Benchmark 2014, the first Class I, Division 2 certified heated oil centrifuge. Today L-K offers a full line of lab centrifuges and lab heaters designed specifically for crude oil, LP, and refined petroleum testing.

In 2016, L-K Industries acquired Miller-Weber of Texas and opened its ISO/IEC 17025 accredited calibration laboratory in the Houston manufacturing facility. L-K also manufactures precision liquid-in-glass thermometers to strict ASTM standards. The in-house calibration lab allows us to offer certified thermometers, hydrometers and centrifuge tubes to our customers.

Earlier this year L-K joined the WEST family of companies, and through the combined knowledge in all aspects of petroleum measurement  will continue to drive innovation in the industry and bring new value to our customers. Looking to the future L-K is excited to launch our next innovation, the Smart Transport Centrifuge, to be released in Q4 2019. This model will bring field crude testing into the digital age by streamlining the recording and reporting of test data through wireless and cloud storage technology.

L-K Industries continues to bring innovation to the petroleum industry and takes pride that we offer products that are made in America.

North American Custody Transfer Measurement Conference  2019

L-K will be attending NACTMC from June 18-20 in Austin, TX at the Hyatt Regency Austin.

NACTMC brings together meter manufacturers and end users in order to share information about measurement challenges in the hydrocarbon measurement industry. Speakers will also share updates in metering technologies, flow measurement research, industry standards, government regulations, and diagnostic tools. The goal of this conference is to provide information that will help the mitigate current metering challenges. L-K highly values the time spent at industry conference.

NACTMC 2019 is hosted by L-K’s fellow WEST subsidiary CEESI, who specializes in flow meter calibration. Founded in 1951, the Colorado Engineering Experiment Station, or CEESI for short, offers flow meter calibrations accredited by the National Voluntary Laboratory Accreditation Program, ISO 9001 and ISO/IEC 17025. CEESI has its main testing and calibration facility in Colorado and a natural gas facility in Iowa.

For CEESI, hosting NACTMC is a continuation of their dedication to education and learning in the flow measurement industry. CEESI regularly hosts training sessions and short courses aimed to educate industry professionals from field technicians and managers to research statisticians.

CEESI also partnered with the Pipeline Research Council International to create the Measurement Library  – a web-based collection of papers related to fluid flow management that is free to the public. Several organizations and conferences allow some portion of their papers to be downloadable by the public through the Measurement Library.

For L-K, NACTMC is an opportunity to share our knowledge with attendees as well as learn about new technology, standards and best practices in measurement.

Calibration Matters!   

Water boils at 212° F. Milk is safely pasteurized at 161° F. 98.6° F means the kids are going to school; 100° F means they’re staying home. An accurately calibrated hydrometer determines the success of a batch of craft beer. It’s also used in petroleum products to measure the standard API scale. Temperature, density, and gravity matter; calibration matters!

MWTX focuses on accreditation and conforming to relevant industry standards to ensure that customers have a high level of confidence in all calibrations performed. The ISO/IEC 17025 Calibration Laboratory is housed in the Houston manufacturing facility and offers calibration services for thermometers, hydrometers, centrifuge tubes, and centrifuges.

Key Attributes:

  • Established traceability of measurement standards and measuring instruments to the International System of Units (SI) by means of an unbroken chain of calibrations linking them to relevant primary standards of the SI units of measurement.
  • Application of procedures to estimate uncertainty of measurement for all calibrations performed and the assurance that calibration uncertainties are sufficiently small so that adequacy of measurement is not affected.

Scope of Accreditation for Miller-Weber of Texas Calibration Laboratory:

  • Temperature:-80º C to 405º C
  • Density: 0.6250 to 1.910 Relative Density (SG)
  • Gravimetric Calibration: Up to 100 ml
  • Rotational Speed: Up to 6,000 rpm

L-K Log December

 L-K Log: December 2018 

Safety Season!

December is upon us, and at L-K, that means more than just the holiday season. Amidst the hustle and bustle of meeting deadlines and wrapping up projects, it’s important to schedule safety checks for your work place, equipment, and accessories. We call it Safety Season!

An important place to start looking for safety slip-ups is with your Personal Protective Equipment (P.P.E.). Safety goggles, gloves, hardhats, masks, Flame Resistant Clothing (F.R.C.), and similar products must be checked regularly for tears, cracks, thinning, and overall wear. As P.P.E. is designed to prevent overexposure to dangerous conditions, it’s critical that these items are in working order. They’re your first line of defense!

Addressing centrifuge accessories is the next logical step in a yearly safety sweep. Inspect all glassware for chips and hairline cracks, including centrifuge tubes, cylinders, thermometers, and hydrometers. Clean excess dirt from all objects, as even small amounts can cause damage. Check ropes, tapes, power cords and the like for fraying and tearing.

Larger equipment, like the centrifuges in the Benchmark Series, should be examined thoroughly. Begin by visually inspecting the product, searching for signs of cracks, accumulated dirt or grease, and any signs of wear. Carefully check the inner bowl. Using gloves, feel cushions and shields for embedded glass, which could cause equipment failure if left in place. An ounce of prevention is worth a pound of cure!

Finally, address equipment from the holistic perspective of age and expiration. If any of the pieces are obsolete, check with L-K to see if they can be replaced by newer, more efficient models. If the calibration has expired, contact L-K. We operate MWTX (Miller-Weber of Texas) which conducts on-site manufacturing and calibration of a large variety of thermometers, hydrometers, and centrifuge tubes. Our focus on accreditation and conformance to relevant industry standards ensures that customers have a high level of confidence in all calibrations performed. The in-house ISO/IEC 17025 Calibration Laboratory offers established traceability of measurement standards and assures a sufficiently small measure of uncertainty. Click here to access the Calibration Order Form.

Additionally, our maintenance plans protect customers who have invested in Benchmark Series Centrifuges. Critical to operating longevity is the annual maintenance guaranteed by this plan. Designed to accommodate laboratory users, all scheduled maintenance is performed at the customer site. Alternatively, units can be brought in for service. Maintenance service includes diagnostic checks, tests for continuity, basic cleaning, RPM and temperature verification, rewiring (as needed), balance correction, and cosmetic touch-ups. Schedule your annual maintenance today!

From L-K to you, have a happy, healthy, and safe holiday season!
